I thought this GPU mod was going to be pointless... Boy was I wrong!

all right so we're maybe a little late to the party on this one but uh phil's been wanting to kind of investigate the overheating memory chips inside 30 series founders edition cards specifically 3080 380 ti and 3090. so today that's what we're going to do we're going to look at the temps we're going to see what we can do to fix it we're going to tear the cards apart hopefully not rip any ribbon cables while doing it otherwise i'll oh fill another 3080 fortunately i have one the elite xg270 qg from viewsonic breaks the traditional ugly appearance of gaming monitors by providing an ultra clean design while still delivering gamers the features that they want most features like a one millisecond response time ips 165 hertz overclock display black brushed aluminum stand with tilt and swivel mouse and keyboard cable anchors and customizable subtle lighting to learn more about the xg270gq from viewsonic and to see current pricing click the link in the description below okay so here's this vram temp in this sensor panel if you guys don't know how i made one of these i'll put a link down below to our sensor panel tutorial but moving forward anyway this is all stock out of the box some might look at this and say but 96 c is totally within spec it is within spec but it's awfully close to the spec which is about 100 to 105. i mean remember those hynex chips they're samsung chips i believe samsung is what we're using in the founders edition cards but running anything at its max rated temperature for any long periods of time is going to lead to its you know life degradation sure it's within spec however if you can run it cooler you can extend the life of that product and we have apparently seen in the wild some 30 series cards that had ram failures because of the temperatures that they were running at apparently people are suddenly finding that the white squishy pad that nvidia has used for ever the last couple decades of their gpus maybe isn't quite up to the task of cooling the ram now caveat here phil did already apply thermal pads to the back side of his pcb which although there are no ram chips there there are that's the solder points and he does get transferred through that metal so he's transferring that heat to his back plate to help dissipate some of that heat so what you're seeing here with this 94 to 96 c bouncing around is with some of that heat being spread through the back plate and then removed through his case cooling mine on the other hand over here chips on the front and on the back and my temperatures although gpu core and hotspot are lower than his my ram temperature is continuously bouncing at 100 c this is also all stock except for the power limit wow that is toasty i wish i had my thermal camera kind of going right now that is very hot so when it comes to the amount of temperature now the 30 90 is also in its best case scenario because of the fact that it's on an open air test bench so you can imagine if it were an enclosed case it would probably go even higher than that and then we'd start hitting to where we're going to start getting when ram gets too hot it's a lot like an nvme ssd where you'll start to get these weird clock speed fluctuations to try and cool it down and if your ram speed is constantly fluctuating all over the place that can lead to things like micro stutters pauses other long term stutters or just jitterness in your gaming so we are looking for cooler than 94 96 because that's where his is bouncing or 100 c on mine all right so these little guys right here are magnetic that stick in there so i just take some tape oh we got all but one there we go so that way we don't lose them they're stuck to the tape now uh and they do go in specific orders if you guys were curious about that um it's been a while since i've taken one of these apart and i don't want to go watch steve's video i don't have that kind of time also this is not a tutorial on how to take this apart if you guys want to take these cards apart you are on your own to figure out who you're going to trust to teach you [Music] okay that's a lot of power delivery on the back side so here's the memory chips on the back as we were talking about right here and these are way thin and these are also the fabric type basically they're a fabric that's kind of like infused with like a thermal paste kind of a deal if anyone's curious that's why these retention plates exist again when they haven't been on nvidia cards in forever it's because with the size of the die 30 90 die and 3080 are bigger than they've been in a very long time the only way they could get enough paw a proper tension to get good cooling was to start using these retention brackets see how i cut my finger on that so it didn't fling so something people need to be cognizant of think of it as like a leaf spring in a truck it's like card to cooler ratio look at the diet look at the dye pattern the the it's not bad there's a spot that wasn't touched at all look at the cooler it's dry there and dry there and it's also very flaky look at that all right let me get this thermal paste off let me get this grease all cleaned up let me get these thermal pads off and then we'll start replacing these thermal pads normally we would apply the pads directly to the graphics card uh we're doing water blocks and stuff however the stock cooler here as you can see has these raised areas that are also machined there's still some stuff on that one that's usually that's machined um which is a perfect template for us to know where to put pads so i'm going to put pads everywhere you see this gray which will make things a lot simpler we're using the two millimeter pads that we use on our ek water blocks i'm a little concerned that if these pads are too thick that they're going to keep the gpu die for making good contact however we've already watched other folks do this with 1.5 millimeter 2 millimeter and 2.5 millimeter so we're gonna go two millimeter on the face seeing how thin the back the ones were on the back plate i think i'm gonna be fine with two millimeter across the board they will squish um if i see any sort of negative temperature improvement in terms of it goes hotter then we know that the pads might be too thick and are causing it to stand off so that the gpu die is not making good contact with the cold plate right here that's attached to the heatsink so before we button this up and uh we're not going to bore you guys with doing the same thing on the 3080 it's just the 3080 won't have as much as it's going on in the back i mean maybe it will already did thermal pads i don't did you do these too like the no okay if we have enough pads we'll see if we can get the back sides of the power delivery cooled um but anyway all cleaned off from here you can see the indentations where they were expecting stuff to be cool so they just put like a right so we'll see how well this works all right so here's what we're dealing with um i changed the pads again off camera because these pads were too thick which just like i was worried might happen it was causing the cold plate to not touch the die fully which meant we under load immediately had the hot spot go to 105 c which means the fan go to full speed it fully throttle itself so i took these off i then switched the two millimeter pads to the one millimeter pad our core temps are amazing this is near water block temps our hot spot is at 67. so tendency difference between our our gpu temperature hotspot but our ram is still at 100 c it'll actually go as high as 104 at times sometimes 102. so now we're thinking that the 1ml pads might be slightly too thin the problem is i don't have any 1.5 millimeter pads that i know of i'm running out of pads to do this with and then not like or have enough left to do fills [Music] all right so with enough trial and error getting the height set just right and even stacking some pads we've got some improvements here my memory is bouncing between 86 and 88 the longer the test runs it does start to climb as you might expect because the fan curve is maxing out at 59 so eventually the cur it does start to go above it but from 100 c or the previous run like you guys saw but up to 104 c that's about a 20 c drop from there 59c on the core 69 on the hot spot on the core so there's definitely an improvement to be had now that we've figured out the proper height we can go ahead and do fills the core temperature drop though i i firmly believe that's the kingpin paste right there because the paste you guys saw was having to scrape it off it was super like cementy oh i also use really thick pads on the back plate i have a theory that my back uh memory pads were not touching the back plate at all which then meant the thermal pads that were on there were acting like insulators making the back memory hot and of course that heat's going to transfer 360 through the card through the pcb onto both sides of the chips causing it to go as hot as it was but still 60c on the core 70 on the hot spot 86 on the ram but when we were seeing that 104 degrees with the pads not touching right we were at 100 fan curve when we were testing that as well and so that clearly was not working now that we've got the height sort of figured out and yes uh 1.6 millimeters or so is about the proper height which we don't have those thermal pads so we had to stack thermal pads and before you say that those that doesn't work clearly it's working it would be more efficient if we had the proper thickness of pad we're going to go ahead now do phil's card and then we'll see uh whether or not i kill his so not really much of a change if anything we're actually two degrees hotter on the ram on the 3080 with the same stacked ram pads that we did on 3090 there could be some variance there between the heights right okay so we just stopped the video there because this is the next day now phil took his graphics card home and he was like hey it's actually worse he was hitting 105 c memory temp at home which is a little bit hotter environment than here in the warehouse although it is 72 in here right now so it's not that much warmer or colder i guess but he was like yeah he would he would load up you know his uh rocket league and was seeing 105 c and we're not in gaming so he's like i think something's wrong so here's what we did we brought it back here i took it apart i used the thermal pads that came off the stock strix cooler without which are the gray squishy nice and squishy ones and check this out this is what we're getting now 63.7 on the hot on the uh die 75 on the hot spot 80 c on the memory 20 celsius drop from the 100 he was like getting near before obviously 25 dropped from where it was with the bad pads now we forg we set this up we're like let's let the temperature run and we forgot about it we went and we're watching videos and we were eating lunch and we were just bsing and here's your proof of how long this is running so when it comes to those temperatures adc on the memory clearly it's doing its job and the reason why the core came down remember we were at 69 to 70 c on the core inside of port royal now we're down to 63. we dropped set almost 7c about 7c on that because of the fact that my theory is that the stand the pads were not squishing down on the ram properly uh which was causing the the cooling plate or the cold plate to not touch the core heart like firm enough that way it was a little bit warmer it was good contact but not the best contact which is why we saw he saw a temperature reduction even on that last install thermal pace but we saw even more now but it needs to have extra squish on the thermal pads for the memory on this now i feel like i want to redo my 3090 with these pads as well my 3090 is also only hitting adc as it is right now so i kind of feel like it's not necessary so if you're using a 3080 i recommend it getting those gelled pads that the gray ones that are thick and squishy stealing them from a graphics card that maybe you don't need anymore or whatever because any of them are gonna be better than that white fabrics putty crap that nvidia uses obviously you can see these temps are better the core temps reduction obviously is through using really good thermal paste like we're using the kingpin stuff the kpx which is obviously um a lot better in my opinion than what the hard cnet stuff wasn't a video was using so better thermal paste better thermal pads you can see now i mean like the memory is already back down to 36 c so it got its job done anyway guys thanks for watching i know we're a little late to this particular mod but um phil was like i don't kind of want to look into this because he noticed his attempts were getting too high and i never even paid attention to the 30 90s now we got two of these founders edition cards that are now cured of the nvidia curse with those white pads that they've been using forever alright guys thanks for watching as always we'll see in the next one
