I don't usually write reviews but I will forward this review to anyone who needs help. I haven't been happy with heavy mining, although it's within reach and certainly better than the 95C I've seen on air. My GPU also ran at 40C with a block. So I knew it was a contact issue or cheap pads. I bought the 1.5mm pads, the same ones that came with the block, and changed the setup with them. My memory temp is now around 66-68C. This is a huge improvement and will certainly help extend the life of the card. It's really hard to cut but I used a paper cutting table with a sharp blade to cut it to size, there's more than enough material for a 3080 and I'm pretty sure it's for a 3090. Also, it's a beautiful piece and well worth removing and reinstalling the water block. Good price too!
