I bought these to replace 18 year old thermal pads on my GPU and Gamecube CPU. In truth, the stock pads were still in great shape, but I cleaned the inside of the console anyway, so I figured changing the pads wouldn't hurt. I chose pads with a thickness of 2 mm. The bearing pads were about 1.5mm. But to be on the safe side, I chose 2 mm. They worked great. The pads are easy to cut, sticky enough to stay in place but can be adjusted if needed. These are not self-adhesive pads but due to their composition they have a slight stickiness which makes them ideal when you want to adjust something. So far the Gamecube works like a cucumber. Highly recommended.
