PTM7950 by CSGR 40x40x0.25mm Phase Change Material & K5 PRO 20g Thermal Paste Set – Top Recommended Cooling Solution for PCs & Consoles

After 3 months of usage, I try another PTM product.It turns out that another PTM is 1~2C cooler on core and 2~3C cooler on hotspot and the fan speed is 100rpm lower on desktop GPU and 1~2 gear lower on my laptop.I'm not sure why the difference between these two PTMs. This is still good. But there is a better one.=====1 40x40mm is good for 1 10750H, RTX2070 and RTX3080Ti(desktop). It's like a sheet of American cheese. You can piece it together.I limited 10750H to 30~35W before. After PTM, I can increase to 45W and temp is about the same while running Timespy.Both PTM7950 and K5pro are applied on RTX2070, VRM and VRAM. GPU temp is about 2~4C lower. But delta of hotspot and GPU is further 2C lower. That's much better than some popular thermal pastes. I applied way too much K5 on VRM and VRAM, and that 20g K5pro should be good for 3 sets of RTX2070(laptop).PTM7950 on RTX3080Ti only, no K5pro. RTX3080Ti is 1~2C lower but fan is also 200rpm lower. Delta of hotspot drops to 6~8c. It was 8~11C before.Btw, PTM7950 does need a few heat cycles to get better performance.
