Google reckons it's the PCH (Platform Control Hub).
Re: SSD temps - both HWInfo and WD's own software. Each only reports one temp for each drive.
Maybe you should give CrystalDiskInfo a download and see if the temp reading there matches up with what the other two say? Just checked and it defo shows the flash memory temp and not the controller.
One other thing and this is for any GE66 owners out there, during your Timespy runs are you able to get the GPU core to go higher than 1,750 or so? It boosts higher than that during the demo part of the benchmark, but for the actual benchmark I can't seem to get it higher than 1,750 or so no matter what I do, yet during games it can go as high as 2,050. It's very strange.
