筆記本散熱器大橫評！ 一半都是智商稅？！ | 筆吧評測室

It's been really hot this summer Here in Shanghai, there are yellow and orange warnings for high temperatures. I've heard that North China has broken several heat records in a row. It's not just people who can't handle it. The computers can't take it either. Especially the poor heat dissipation of the game book. It's 90 degrees or 100 degrees when you play games. It's like adding insult to injury. No, no, no. It's adding fuel to the fire So all kinds of laptop coolers are on hot sale again. But so many coolers How to choose? In order to figure out this problem We have purchased N kinds of coolers at our own expense from the price, temperature, power consumption, noise, compatibility, etc. Compatibility, etc. We have tested them in detail Evaluation is not easy Please give us your praise first We'll start right away Before buying a cooler First of all, you need to know where the cooling bottleneck of a laptop is. Most of the current coolers Most coolers are designed to enhance cooling by increasing the air intake of the laptop. So if your computer is already a bottleneck in the air Then the cooler will be more effective On the other hand, if it's not an air intake bottleneck But if it's not the air bottleneck, but the heat pipes, silicone grease and so on. The effect will be less effective. It's easy to check. Just lay the laptop flat in the oven once and then bake it again with a bottle cap or something. And compare the results. We've got two gaming laptops. One is a 2021 G15 Razorback. It's an air intake bottleneck. After the cushioning of the fuselage. CPU power consumption is 1W higher The graphics card is 10W higher And the temperatures no longer hit the wall. And the 2023 Aurora Pro intake bottleneck is less pronounced Only the CPU power consumption is 6W higher with the pad up The graphics card, on the other hand, is virtually unchanged Then briefly introduce the contestants in this issue Currently, laptop coolers can be roughly categorized into Passive cooling and active cooling two categories Passive cooling has a simple structure The price is also cheap However, it can only provide basic cooling effect The active cooler has many different types There's this fan mount with fan for less than 30 bucks There's the classic side-vented cooling There are also more expensive ones like these semiconductor coolers and pressurized air cooling bases. And on top of that. We have prepared one more thing As a special guest to compete with them Let's take a look at them one by one The first one to introduce is of course our bottle cap method. The principle is very simple It's simply padding the machine to increase air intake. Works well for machines that have their own short footrests It's very good value for money, portability and compatibility The only drawback is that it may not be very stable The only other disadvantage is that it may not be very stable, and it may not look very high-class. So, I'd recommend these collapsible caps over a bottle cap that costs nothing at all. I recommend these foldable feet. It's glued to the laptop with 3M adhesive on the bottom. The angle of the cushion is similar to the bottle cap But the stability is much better Usually can be folded up without affecting the portability The price of such a pair of foot mats is 5~20 dollars It's a low-cost yet elegant solution. We used it to measure the results of the previous cushion. However, it's not as effective in controlling keyboard temperature. Even due to the increased power consumption of the core. The surface temperature of the G15 is still rising. Next up is this M-shaped folding stand. It also increases air intake by raising the end of the stand. Compared to bottle caps and folding feet It's a little less portable The advantage is that the angle of the stand can be adjusted So many people will adjust it to a big angle To relieve cervical fatigue This kind of stand also ranges from 9.9 to over 20 dollars I suggest to choose this kind of metal material It's more sturdy Or pay more for a "high end bracket" such as the Saver. The workmanship is much better But the price is many times higher. As far as cooling goes On the G15 The stand is better than the feet CPU power consumption is 2W more The graphics card is almost 4 degrees lower And on the Aurora Pro it's the other way around But it's still better than laying it flat Not much effect on the surface temperature There's also a special type of grill This solution, although at first glance it looks very pheasant But the real-world results are surprisingly good On the Aurora Pro CPU power consumption is only 1W different from the folding footpad But the graphics card is 2 degrees lower On the G15, it's even more obvious Both the CPU power consumption and graphics card temperature are ahead It seems that the effect of raising the whole laptop It's better to raise the whole laptop than just the rear. Of course, it doesn't work on surface temperatures either. But there's a problem with this grill. It's just that with the laptop elevated. It's not easy to use the keyboard So it's better to use it with an external keyboard. This way you can store some small things underneath the stand. Price The one we tested was bought for 8.8 dollars from Poundland. But I really don't recommend it Because its overall strength is very low It doesn't feel like it can hold a heavy gaming laptop. Like this $18.80 "advanced" grill. Much more stable A little more colorful, too These passive cooling stands In short, they just hold the computer up in various positions. There's nothing fancy about them But when it comes to active coolers, they are all different. There are different types of fans and cooling methods. First is this most common The most common is this one with a fan on the bottom It's not much more expensive than the previous ones. The Taobao pop-up [Core IceZone] in this test is only 26.9 yuan Basically in the same price range Its improvement over the ordinary bracket is the addition of two fans at the bottom Can be blown upwards Further increase the air intake of the notebook However, in practice, the improvement is very limited. The core heat dissipation is almost the same as the front grill. The surface temperature is about two degrees lower It's barely perceptible. （I think the reason is that the airflow is too small. Although we got the high revving deluxe version But the actual airflow is not much Just enough to hold up a Kleenex. In terms of noise Its body noise is 45.2dB It's a relatively quiet level The addition of this device will not increase the noise level of the laptop. Overall This cooler is a bit of a dud First of all, its cooling effect is not much better than the passive cooling bracket. And the portability is poor Plus it's just a little too roughly made In the front, you can get an all-metal stand for 20 bucks. But for 20 bucks, you can only get a plastic one. The durability is a concern. Of course, there are high-end models It's also a bit more expensive In addition to the regular fan bracket There are also some special coolers Like this one The turbo cooler that looks like a cassette oven It also enhances cooling by blowing air into the bottom of the laptop Due to the barrel shape of the design It's a bit more portable than a regular fan base There is an adjustable slot at the bottom of the cooler It can be used to fit different sizes of laptops You can also put your cell phone or tablet on it. You can even stand it up As a small USB fan. However, the compatibility of this cooler is very problematic. In theory. Our laptops should be on the front card slot But if your laptop has a rear power connector The plug will conflict with the radiator. Besides, its cooling performance in the real world is not satisfactory. The power consumption and temperature are not only worse than the Core IceZone. It's even worse than a purely passive cooling grill. The problem lies mainly in the air ducts. This cooler has an upper air intake The air comes out from the bottom Once you meet the current mainstream tail-end ventilator. It's like sucking in the hot air that's just been discharged. The surface temperature Aurora Pro will be slightly lower G15 is almost the same Its body noise is 49.8dB (may) slightly increase the overall noise of the gaming laptop but it's still acceptable In terms of real-world data Green Giant's cooler doesn't do so well as a cassette-style furnace. Plus the $110 asking price It falls into the non-recommended category If it's paired with a non-tail outlet, non-power rear mounted machine Then it should be a bit more adaptable Measured two coolers with fans I feel that the effect is not very good ah Is there a more powerful air-cooled cooler? There is one in our tests It's the pressurized air cooler represented by Old Horse. Its principle is slightly different from the conventional air-cooling Others just blow air into the bottom of the computer. It has memory foam between the computer and the fan. It's sealed. It's like "disliking" the air directly. In addition, its airflow is also very large Even if you put your laptop on it without turning it on. The air outlet can even blow up paper towels. Let's take a look at the result. At the highest speed Aurora Pro's graphics card dropped 11.8 degrees The CPU is only down 1 degree. But it's no longer hitting the wall Power consumption increased to 55W from 38W in the flat The effect of G15 is more obvious Graphics card dropped 21 degrees Power consumption also increased by 10W CPU dropped 12.5 degrees Power consumption also increased by 10W The surface temperature drop is also very dramatic The center area of the Aurora Pro dropped almost 10 degrees. The G15 is almost as good as a standby. But this cooling effect does not come without a price. That is the horrible noise The noise level of this cooler is 70dB at full speed. It's louder than any gaming laptop we've ever tested. After placing the laptop Because the air vents are blocked The overall noise drops to about 65dB But it's still very noisy We recorded a video For your information. So, we also tested it at half RPM. The results were good. Only a small increase in temperature The power consumption remains the same. The surface temperature increased slightly. But it still kills all the coolers in front of it. At the same time, the overall noise level drops to 58dB. which is barely acceptable If you need a very powerful If you can save an old gaming laptop's cooler. This would be the strongest model we've tested. But it's got its drawbacks. Besides the noise. It's not very portable It weighs 1.6kg Only suitable for fixed scenes The exterior is also very rugged Feels like a better match for Shenzhou's gaming laptop The price of around $300 is also on the expensive side of all the players There's one last thing I'm worried about. After all, it's pressurizing air into the laptop. It's going to increase the speed of the fan. And if it's idle, it'll turn into a generator. "reverse power" to the motherboard. This may affect the life of the fan. I have no way to verify this. I hope those who have used them can tell me about them. After talking about these blowing coolers. There's another product that was popular a few years ago that's worth trying. It's this extractor style radiator Unlike other competitors. It needs to be fixed on the side air outlet of the laptop when using it To increase airflow by pumping air outward So the advantages and disadvantages of this type of cooler are also obvious When encountering a laptop with only side vents or a laptop where the side vents dominate It's very effective However, in recent years, most of the gaming laptops have four air vents. And the airflow is mainly from the rear This radiator would be easy to deflate In real-world testing This cooler does nothing to improve the core cooling of the Aurora Pro and G15. It doesn't improve the core cooling of the Aurora Pro and the G15. Individually, it's not as effective as a folding footpad After extracting the heat Aurora Pro's surface temperature dropped But it's useless for G15 Due to its small size and high speed It is also noisy Overall about 56dB It feels like this radiator is a tear in the eye of the times It used to be very versatile But in front of the more and more complicated laptop cooling design nowadays It's not enough anymore At a price of about 80 dollars If it's an old-fashioned side-vented computer can still be considered Recent years of multi-outlet laptop is really not recommended In addition to the above conventional air-cooled coolers In recent years, a semiconductor cooler has become popular The promotional page is written all over the place. "Ice porcelain superconducting technology "58 degrees" and so on. We also bought a test The core of this radiator is a semiconductor cooling pad Its operating principle is the Peltier effect When the electric current passes through two different materials connected in series to the electric couple According to the direction of the current The contact point will appear heat absorption or exothermic phenomenon According to this principle, the corresponding semiconductor materials are connected in series. It is possible to make this kind of cooling And heat at the same time. And then put the cold end close to the laptop And put a fan on the hot end to dissipate the heat. It's a semiconductor cooler. Specifically on the actual product There are three kinds of heat sinks that I've bought. The first one is the Biazza. There's a cooler in the center. Surrounded by a bunch of fans. It feels like an upgrade from the previous model with fan brackets The problem with this cooler is that the cooling pads are rigid. There's no way to make effective contact with the laptop The second one is more of a modified version of the pressurized air cooling. The center is recessed to provide a relatively airtight seal. There are two air inlets and a fan at the back The center cooler has a spring underneath. So the fit is a little better than the one above However, it's not very compatible. Although it says it supports up to 21 inches But in reality A 15.6" G15 would be blocking part of the air intake And the 5V2.5A power supply specification is also a bit too low for a semiconductor cooler It's worth mentioning that This appears to be a male-molded product Under several different brands Under several different brands, you can find similar designs Let's take a look at the results For Biazza. On the Aurora Pro Core cooling not as good as folding feet On the G15 it's a little better than a folding footpad But it's only 50 50 with the $27 Core IceZone The other cooler is the opposite The Aurora Pro is on a better par with it It's on the same level as the Core IceZone The G15's air intake is too much blocked. The heat dissipation is seriously regressed Obviously not as good as the footpad It's even almost as good as laying flat On the surface temperature Only the Aurora Pro with the H6 cooled down about 2 degrees Other combinations are basically unchanged Noise The Biazza is a little noisier Overall These two coolers are very mediocre They go back and forth with the bottle caps and the feet Combined with a price tag of over 200 Falls into the category of not worth buying at all After testing the two duds. I've almost lost faith in the semiconductor cooling category. Can't we find a working product in this field? I don't believe it So, I spent another 799 dollars From Lenovo's website. "Lenovo's website, and got this SAVIOR TEC Thermal Deck. The principle is different. Other semiconductor coolers just stick the cooling pads on the laptop. Instead, it connects the fan to the cooler. This way the air is cooler than room temperature. It's a little more reliable than the first two. Looks good. How does it work in practice? In two words. Not so good. With the Aurora Pro CPU temperature and power consumption is similar to the previous Core IceZone. Graphics card temperature is 1.4 degrees lower Barely ahead With the G15, it's barely a difference. Again, it doesn't do much to lower the surface temperature. In contrast to the cooling effect. It's ridiculously noisy. It's 66.6dB. With the addition of the machine, it's also 63dB. It's second only to the old horse's pressurized air cooling. And the sound is sharp It's very uncomfortable. Although it offers 4 air speeds to choose from But the highest speeds don't do much to dissipate the heat. The lower speeds don't make much sense. It's a purely IQ-taxed product. It cost me 799 dollars For the sake of my self-funded help for everyone to step on the pitfalls I hope you'll give me a trifecta to get back my blood. Of course I can't step on this pit for nothing Now that I'm here. Well, it's got to be taken apart and studied. Remove the cooling fins and the deflector. It's easy to see what's wrong. I thought these copper fins were the cold end of the cooler. To cool the air coming out of the vents. It's actually the opposite. They're actually connected to the hot end. And these sparse pieces up here are the cold end. This leads to The cold end doesn't have enough contact area with the air Very limited cooling effect on the outlet air How bad is it? At 25 degrees room temperature In the highest gear The air temperature at the vents can only be reduced by about two degrees This ...... Feels like it's not as good as turning down the air conditioner by two degrees In fact, the surface of its cooler can drop below 15 degrees But because of the heat transfer efficiency The air vents can't cool down at all Also, there's something wrong with the design of the fan. It splits the airflow from the fan into two parts. The top half blows the cold end of the cooler The bottom half blows the hot end of the cooler It's like one fan doing two jobs. The result is that the actual airflow is very limited And only less than half of the whole bracket can produce air. I feel that the design of this cooling deck is still a good idea. But when it comes to the actual product, it's full of flaws. It's just a half-baked product It seems that none of these semiconductor coolers perform well on gaming laptops So is there a possibility Is that their cooling power is too low for a gaming laptop? Wouldn't it be better if they were replaced by thin and light computers Wouldn't it be better? Holding on to the last ray of hope I found this extraordinary Go 14 for testing. When it's laying flat The power consumption of the grill is 40W About a quarter of a gaming laptop The bottom also fits the radiator's cooling fins. After this measurement A couple of radiators are better than a passive cooling grill. But it's not much better. At most, the CPU power consumption has increased by 2W. It's still 100 degrees Surface temperature did not drop much As you can see Even for a thin and light notebook with a power consumption of more than 40W The effect of these coolers is still not obvious My guess. Probably only fanless laptops like the MacBook Air and MateBook X fanless laptops like that They're only effective with them Other laptops are really a no-brainer After testing so many coolers My overall feeling is a bit disappointing Except for the noisy pressurized air cooling of the old horse There is nothing that works particularly well Is this the end of the road for external cooling? Don't forget. We have one more thing in store for you this time. That's Mijia air purifier Although it's not designed for laptops But it has a huge airflow and relatively flat air vents. It's perfect for use as a cooling base. We grilled the machine at the highest setting We can see Its effect on core cooling is almost the same as the old horse's highest speed. It's all a core drop of a dozen degrees It also comes with a power consumption increase for the CPU Its advantage lies mainly in noise and surface temperature In terms of noise In the highest gear is only a little higher than the old horse in half speed Far lower than the full speed of the old horse And the surface temperature is undoubtedly the MVP. It's cooler than the old horse at the highest speed. The computer is freezing cold This is mainly because The old horse can only blow air from underneath the machine The air purifier has air coming out from all sides. The air flows better. All in all, it's not a very practical solution. But at least it helps us to validate one possibility. Power can really work wonders. Many of the previous radiators are limited by size, power and cost. The airflow can not be done That's why the effect is mediocre But in front of the purifier this absolute air volume Even without targeted optimization Even without optimization, it still dissipates heat very well. Well, after all these measurements. I'm sure everyone's head is spinning. Let me briefly summarize the purchase advice For most of you who are not particularly demanding I still give priority to the bottle cap method Or this kind of folding foot mats that cost more than ten dollars or so It can be the lowest cost The highest portability and compatibility Provides decent cooling Can be unbeatable in terms of price performance ratio While other passive cooling mounts The effect is similar to the bottle cap The main thing is to provide an additional function to support the computer For laptops in fixed positions may be more comfortable to use It is also recommended When it comes to active cooling Like this Taobao Jinduoduo pop-up stand with fan It does dissipate heat a little better than a purely passive mount But it's only a little bit better It doesn't have that quantitative to qualitative effect. Considering the cheaper price It's not exactly an IQ tax I can only say that it's not a bad deal if you buy it I still prefer the front passive cooling bracket. At least they're better for the price. The turbo and extractor type coolers like Green Giant and IETS. are not as compatible as the others. It's a little out of date. There used to be a lot of laptops with a single side vent. Like the old Flying Fortress. ThinkPad, etc. But in the last few years. Gaming laptops have gone to four vents. Thin and light laptops are basically screen vents. The two of them can't cope with the current mainstream machines. Only some old computers can still be adapted to a little bit. Semiconductor cooling radiator is the least recommended category in my test. They were the most numerous and expensive of the products tested. And none of them can beat them. The best of them are just like ordinary fan mounts that cost a couple of dollars. I can only say that semiconductor cooling is still very immature in laptops. Most of the existing products are IQ tax. Do not buy Finally, there's one more thing worth considering It's a pressurized air cooler like the Old Horse. Its advantages and disadvantages are very prominent The heat dissipation effect is much better than other products For some machines that are highly affected by the temperature wall It can significantly improve performance But it's noisy And portability is almost non-existent It is only recommended for those who have a fixed machine Users who are not sensitive to noise To be honest. I didn't expect this video to be so long when I first made it I hope this much data can bring you some help Finally, I would like to remind everyone These external coolers can only play a secondary role. The heat dissipation of a laptop is still largely dependent on its own strengths Gaming notebooks like the G15, where the graphics card is originally limited by a temperature wall After installing a cooler, it can drop a few degrees no longer hit the wall It's already an obvious improvement It's not realistic to expect to rely on the cooler to achieve a comeback In addition For older machines Fan dust accumulation and silicone grease aging can also affect heat dissipation You might want to try dusting and changing the silicone grease. It's probably a lot better than these heat sinks. Well, that's all there is to the video. If you like it, why don't you give us a long press to like it?
