That being the case, I removed the heat sink - which didn't look
very dusty - and cleaned it thoroughly.
The thermal transfer paste looked kind of sickly, so I went to
Radio Shack and bought some new paste. Went for the cheaper
white stuff at $3.50 instead of the $12.00 silver on the
assumption that marketing was at work there.
Scraped both sides clean, applied the new paste, re-fastened the
heat sink... and no change. GPU still at 60C.
Eyeballed the heat sink fan and it is working. SpeedFan says
it's turning at about 1,400 RPM. Fan's 2-5 in SpeedFan's list
are all at zero RPM... but looking into the box, I don't see any
other fans on the mobo.
Temps of the two internal hard drives are in the low thirties.
Temp of a hard drive in a SATA sled is 29.
- Are my assumptions correct?
- Did I make a mistake by chincing out on the thermal
- Might there be other reasons for the high CPU temp?
