RTX 3090 (and 3080) Owners! CHANGE Your Stock Thermal Pads! (Guide, Tips, Results) w/ Dr. JimRPG

RTX 3090 Owners - have you had problems with your memory temperatures? Me too! After testing it out using various GPU settings (default/undervolting/underclocking), trying in various games to max out the memory temps in games like Skyrim, MS Flight Sim 2020, Cyberpunk 2077, Red Dead Redemption 2, and even putting on a cheap fan and heatsink, I noticed the temps were getting worse. And it was finally time to do the thermal pad mod, and I'm glad I did. The aftermarket pads are much better than the factory ones. Obviously this will depend on what the AIB Board Partner uses, I only have an MSI RTX 3090 Ventus 3X so I can't tell what temps will be on other cards, but if you are struggling with memory temps, its worth considering swapping out the thermal pads. Use my guide and tips to help you, make sure to check out all the other videos on youtube so you're well informed before doing the mod!
