Recently I've upgraded to an 8800GT, got a new Biostar nForce4 board, and new 600W Rosewill PSU. Yes I know Biostar and Rosewill aren't exactly top quality, but they should get the job done. Long story short, failing Antec PSU fried old DFI mobo and 6800GT.
Here I am now, thinking I'm finally back up and running, but I start getting random shutdowns. They're due to the mobo's auto shutdown protection. At a limit of 60C it wont even finish booting windows. At 70C limit I can game for 2 hours, quit to desktop, go downstairs for ten minutes, come back and its shut down (in other words, HUH?). I've got three 120mm case fans all running at FULL blast, 2 of them getting full power from 4pin molex and one in the PSU set to High. MBM5 and speedfan both report an idle CPU temp of 93C, chipset 70C, and PWMIC 127C. The CPU and chipset heatsinks are both cool to the touch on idle. I guess this means either the sensors are wrong or each heatsink is failing to do ANY cooling and is instead insulating (doubt that. 1 factory installed, one self). I guess I will feel them under load next...
GPU idles at a mind-soothing 48C. Aside from disabling the auto-shutdown protection, what can I do here? Thoughts on the validity of the temp sensors? Thanks.
EDIT: Further testing reveals Prime95 + Compressing a DVD = heatsinks become warm to the touch, temps reported do not change.
