Hi. Very interesting. So what are your peak temps during heavy use?
Hi. Im back with a lot more test results.
Ok so I was wrong. I don't know why my temps were so high when I first installed the NVMe and the thermal pad that comes with the Maximus XII hero.
When I removed the thermal pad and the "heatsink" (that metal piece that covers the NVMe) my temps didn't really improve much. Only by like 3-5 degrees c. Because of this I decided to do some real testing. I have free time today so I said "why not?". I downloaded CrystalDiskMark (already had crystaldiskinfo) and decided to benchmark my NVMe. Long story short my NVMe hit 80c while doing the write test. This was with no heatsink cover or thermal pad just out in the open.
So after seeing this I decided to disconnect my PC remove the GPU (to be able to get to the NVMe) and reinstall the thermal pad and heatsink (the metal plate/cover).
However, this time I installed it in a different way. What I did this time was to actually remove the thermal pad off the metal shield/heatsink/plate (whatever its called) and put the thermal pad directly on the NVMe itself that way I know I have 100% coverage over it. I did have to make a small cut to the thermal pad as it was too long. Once I cut it to a perfect size (to cover the NVMe perfectly) I went ahead and carefully place it onto the NVMe itself.
After this I put back the metal plate/heatsink, screwed it in and placed back the ROG logo over the RGB LEDs.
I also made sure to tighten up the screws kinda "tight". The first time I installed the NVMe and I placed the metal plate/heatsink with the thermalpad stuck to it over the NVMe I didn't tighten the screws too much I left them kinda loose because I didn't want smash the NVMe (yes I know kinda silly but it was my first time installing a heatsink and thermalpad over a NVMe).
Anyways after all this I put the PC back together blah blah blah and ran CrystalDiskMark once again. I ran the whole benchmark (benches the read and write speeds of the drive) and I was shocked to see a MASSIVE improvement in temps.
I went from a max of 80c to a max of 45c after this. A huge improvement. Before I forget, I also left the sticker on the Samsung 970 evo plus. I simply just put the thermal pad over the little sticker.
Im very happy with the results now.
Having the thermal pad and metal plate/heatsink on the NVMe makes a huge difference. I don't think I have anything to worry about while i'm gaming even if the NVMe is right under the GPU.
I noticed the NVMe only gets hot when it's writing, not so much when it's reading. So while i'm playng Final Fantasy XIV or Resident Evil 2 Remake it's only reading and not writing.
Thanks to everyone who posted here and offered advice. I hope this can help anyone else who's curious or is having issues.
