The SKETCHIEST CPU Cooler

so you got this computer that you gotta cool this looks like a fairly simple problem to solve right i mean intel doesn't even include copper slugs in the middle of their hunk of aluminum heatsinks anymore so why is it then that we pay actual money to cool our processors i mean in the case of the stock one i guess you don't really pay for it it comes in the box for nothing but maybe you broke it or something so today's mission is to build our own cooling heatsink [Music] i buy power and msi's new lineup of gaming laptops feature intel 7th generation core i7 processors check them out at the link below so with the mission of creating our very own linus tech tips heatsink i set off for a discussion with the linus media group engineering and stuffed animal taxidermy division they went away for a couple of days and then returned proudly producing a hacksaw a block of aluminum and a stack of papers full of pictures of elon musk over which in crayon it said just raw dogget at which point i really began to wonder what exactly it is that i paid these people for and got to work i guess [Music] so the basic principle of an aluminum heatsink is actually pretty straightforward you've got this little heat generating doodad right here and you need to take that heat and you've got to spread it out then you've got to dissipate it to the air so what you need is a thermally conductive material so the engineering department did manage to get that far we've got a hunk of aluminum which has excellent thermal conductivity and then what you need is you have to increase its surface area so if all we did was take this and stick it on top of a cpu what we'd effectively do is we would spread the heat but we would spread it throughout this block without actually achieving any of our cooling goals so once we've got this spreading the heat we've got to increase the surface area and the way that apparently they intend for me to do that i mean at least they have the decency to get a fresh blade for the hacksaw is to throw the block in the vise and just start sawing out fins i've been informed that this is the good one whatever that means so we're gonna do a practice cut on this other hunk of aluminum see just how accurate we can get here the more fins and the thinner the better okay unless we have all the time in the world and we assign absolutely zero value to it that's clearly not a way to go about it so back to the engineering department they brainstormed and came up with a new solution let's arm linus with power tools so i've never used a reciprocating saw and it's plugged in but it looks really fun so uh safety first kids exciting wd-40 on here wow we made as much progress in like four seconds as we did before okay that's not so hard let's do the real thing see here's my like 10 minutes of hacksawing there's my like 10 seconds of uh reciprocal sawing okay screw it yeah okay [Music] how many blades did you say we have unplugged to change the blade have a lot more respect for what cooler master does i think that what we really need is like a constant flow of wd-40 almost we are definitely making faster progress now so not having not trying to cut the entire thing at once keeps the blade from uh getting so gunked up with metal gonna be really careful we only have one blade left almost there she's got to finish up one last one so we found that this stuff uh fluid film actually does a better job of lubricating the blade which would have been great to know because it's just generally a lot less nasty than wd-40 that's the stuff that smells by the way [Music] almost there [Music] holy crap i think the only thing more epic than the diy heatsink we've created is the mess that we've created i mean this is like i don't know if it's like a pound of aluminum but boy howdy is it ever a lot of aluminum i guess you better clean this up look at this oh there's wd-40 all over it this stuff is hard to pick up okay we are actually getting pretty close to being ready to try out mounting this baby after a little bit of washing and a little bit of filing just to take some of the really rough edges off of it so we don't hurt ourselves while we're working on it we are going to devise some kind of mounting system now that's the kind of thing that you're probably thinking to yourself d linus surely you guys thought of that before you started to which i would reply [Music] it can't be that bad right yes my friends it's zip tie time again so we're gonna throw on our usual icy diamond thermal compound we are going to plunk that bad boy down on there and we are going to figure out how to zip tie it on you know what let's get some hot glue going on here too elina's tech tips project is truly not complete without hot glue so in terms of mounting for this puppy we're just going to kind of just going to kind of yolo it i mean were you really expecting anything else [Music] there we go okay so the hot glue fan is on if we ran this through the holes on the fan it was albert einstein who said that there's a fine line between idiot and genius comments are going to be full of he said no such thing what the crap what kind of cheap ass zip tie breaks just like that let me get these oh they're generic so this is it moment of truth time well posts that's a good sign cpu temperature sitting at 25 degrees we've got eye to load it up let's get our sensors going here idle temperatures not bad and it's not like the fan is working really hard either check this out check this out it's just barely spinning see that so let's go ahead and hit it with a stress test cpu package is sitting at 74 degrees but i think we've leveled off success [Music] for three dollars worth of aluminum and a fan that we found some old 80 millimeter silver stone fan we were able to okay hold on a minute so it's been running for about eight minutes now and the victory is less complete than we at first thought so there's some good stuff to take away here we're still running above the base speed of the i7 6700k but we are not turbo boosting to the max anymore so you can see we're actually getting some cpu throttling and overheating detected here our cpu package is up around 98 degrees celsius and if you put your hands on the heatsink it is pretty toasty but the computer doesn't turn off it does run so there you have it we did what we set out to do we made our own heatsink is it as good as the one that intel puts in the box no but intel doesn't put a heatsink in the box for their unlocked k-series processors anymore so this if you have an unlimited amount of time and enough money to buy literally a power tool just to make it but for some reason not enough money to just buy heatsink okay we don't know what the point of it was but it was fun wasn't it even the name vpn makes browsing the internet privately and in a more open manner sound kind of like techy and difficult but with tunnelbear it is so easy they've got applications for android ios mac pc even a chrome extension and it makes it as simple as pressing one button and then boom your connection gets encrypted with aes 256 bit encryption and oh by the way tunnelbear does not log any of your activity and it changes up the location that you appear to be browsing the internet from so online websites and services will think you're someone else from somewhere else but don't take my word for it you guys can try it out for nothing by heading over to tunnelbear.com ltt where when you sign up for an unlimited account you can save 10 percent so thanks for watching guys if you disliked this

description also down there is our merch store retest shirts like this one and our community forum which you should totally join now that you're done doing all that stuff you're probably wondering what to watch next so check out our recent video maybe it's recent i don't know youtube kind of picks one to suggest to you so the odds of you liking it are actually pretty good [Music]
