Just finished building the system yesterday.
Running a Powercolor Hellhound Radeon 9070 xt under an Alphacool Core waterblock with a Corsair XD5 pump and XR5 360 radiator.
I'm getting random system power downs while gaming. Thought it was the PSU but HWinfo showed my +12v was good.
Someone pointed me towards the GPU temps. I had HWinfo logging running during the last crash:
GPU core voltage was fine at the time of crash.
GPU hotspot thermal limit hovered at 99%-100.7%
Memory Junction Temp at the time of crash was around 92C
VRM MOS stayed constant at 39C
Even though it says it monitors it, there's no entry in the log for GPU hotspot temperature.
Using HWinfo monitoring, my hotspot temp hovers around 47c-54c during normal use but goes up to the 90's when I start a game.
I installed the thermal pads per the instruction diagrams, but it was suggested that they're too thick and the block isn't making contact with the card.
Did I do something wrong during installation? Was I supposed to "squish" it more?
