For the past 2 weeks I've been experiencing a temp issue with my system. One afternoon I heard one of my systems fan kick in. They are set for Cool N Quiet mode only to come on at FULL speed if the system has excessive heat issues. This is set in my ASUS Bios. They are designated by 2 port assignments on the motherboard. Then I ran SIW to see what the temps were I saw the video card with a elevated temp reading of 52c. This is not normal behavior for this card for my system. It usually runs about 40-45c under full load. I'm not a gamer just interested in full HD. Upon further observation the Video card would heat up to these unusually high temps even in idle. This would in turn heat up the rest of the system and the fans would kick in. They spin hard for a few seconds and return to normal.
I assumed maybe something happened to the compound on the passively cooled heatsink and not dissipating the heat correctly on the video card. So I purchased another video card. The new video card arrived and I installed it. This new video card has active cooling with a fan encased in a compartment. I'm fully aware that the new video card would run at higher temps but not at the temps of the previous card which were 50-62c.
What I discovered after installation of the video card that I could no longer see the CPU temps in SIW, SpeedFan or Everest Ultimate Edition. I doubled checked in the BIOS and saw the temps registering in there but no when I'm in the Win7. Before all of this happened I could see everything fine and was normal. I've come to the conclusion its either the PSU, Mobo or CPU which are all new. The CPU being the oldest by a few weeks. I've also re-installed Win7 to make sure it wasn't with Win7 and maybe a corrupted file. It was a shot in the dark. Below is my system configuration:
AMD Phenom II x4 920
Dominator Memory DDR2 1066 2x2GB, Dual Channel Mode
PSU: ABS 700W
Old Video: XFE 8600 GT, New Video: GTX 260
OS: Win 7, x64 b7000, Now: Build 7077
Also, I'm thinking of purchase a new FULL Tower case to give these components more room to breath and place more fans.
Can someone explain to me what happened to the CPU temps even though I can see them in the BIOS?
Thanks for your time & attention,
