I've been trying to modify my 3090 for a while, but a quick search for thermal pads brings up results that are either out of stock or asking for exorbitant amounts. I decided to try them as the thermal performance is very similar to Thermalites but at a much cheaper price. I've used them for VRM in combination with some thinner ones for VRAM and temperatures dropped by 20C at +14% power cap. and respectable Undervolt. Definitely recommend them!
