Which thermal pads are actually going to save my GPU because honestly seeing 106C on my VRAM junction temps is making me lose sleep and I need to fix this before the weekend. I finally opened up my Gigabyte 3080 and the stock pads look like literal oily bandages, it is so gross and leaky. I am stuck between getting the Gelid Solutions GP-Ultimate ones or maybe the Thermalright Extreme Odyssey II. I also saw some people talking about Kritical Pads because they come pre-cut for specific cards which sounds amazing because I am super clumsy with a hobby knife and I dont want to mess up the measurements and short something out.
The Gelids seem to be the gold standard for being soft enough to compress but I keep reading that the Thermalrights have a higher thermal conductivity rating like 12.8 W/mk or something? But then people say the Thermalrights are stiff as a board and if they dont compress enough then my GPU core wont even touch the cold plate and then I have a whole different nightmare on my hands where the core hits 90C instantly. I have about fifty bucks to spend on this and I really need to order them tonight so they get here by Friday because I have a big video project due Monday and I cant have my PC crashing every twenty minutes because of thermal throttling.
If I go with the Gelids are they gonna bleed silicone oil all over my PCB in six months? I saw some horror stories on reddit about that. But then the Thermalright ones are so stiff they might crack the board if I tighten the screws too much... or maybe I'm overthinking it? My card is the 3080 Gaming OC and it is just a heater right now. Should I just play it safe with the Gelid Extremes or is the Odyssey II worth the risk for the better temps? I'm just really nervous about tearing this thing apart and making it worse than it already is...
I had issues with the Thermalright Extreme Odyssey II 12.8 W/mK because they were stiff as rocks and unfortunately ruined my core contact. Switched to Gelid Solutions GP-Ultimate 15W/mK but they werent as good as expected since they leaked oil everywhere after two months.
^ This. Also, in my experience fixing dozens of 30-series cards, everyone obsesses over W/mK but ignores Shore hardness. If pads are too firm, you lose core contact. I once saw a board flex because someone used pads that were basically bricks.
> honestly seeing 106C on my VRAM junction temps is making me lose sleep ^ This. Also, I feel your pain... those Gigabyte stock pads are the absolute worst. I had the same oily bandage situation with my 30-series card and it was honestly disgusting. If you're really nervous about the stiffness of the Odyssey ones, you might want to consider Thermalright Valor Odin 15 W/mK Thermal Pad instead. They are quite a bit softer than the Odyssey II so you won't have such a hard time getting the core to actually touch the cold plate. But tbh, if you're worried about being clumsy with a knife, you should really look at thermal putty. I switched to Upsiren U6 Pro Thermal Putty for my last rebuild and it's basically cheat mode. You don't have to worry about if the gap is 2mm or 2.5mm or whatever weird thickness Gigabyte used that day. You just roll little balls of it, stick them on the VRAM, and the pressure from the cooler squishes it to the perfect height. No risk of cracking the board or lifting the core because it just deforms naturally. Just make sure to grab some MG Chemicals 99.9% Isopropyl Alcohol to get that oily residue off the PCB first. If you don't clean it properly the new stuff might not seat right or transfer heat well. Take it slow and maybe watch a teardown video for your specific Gaming OC model one more time before you dive in. You'll get it fixed in time for your project!
