CPU overheating

Intel Pentium d 925 3.0ghz processor
May 25, 2010 at 17:48:18
Specs: Windows 7, Pentium D 925 / 2ghz

I am trying to diagnose why the fan on my
heatsink is spinning so slow. I have gone into
bios and disabled 'Q Fan Control', so it should
be running at max. However it seems to max
out around 959 rpm. My cpu idles around 60C
and easily gets to 70-80C while active. I have
tried replacing the stock HSF with one I
bought at Micro Center but have the same
results. And for the record I am not over-clocking. The only thing I can figure is that it
could be my motherboard. What is the next
step in diagnostics? Should I try flashing the
BIOS at this point?

Thanks in advance for any help and advice!

"for the record I am not over-clocking"

Your CPU is only running at 2.4GHz so you're actually underclocking. Is that an attempt to lower the CPU temp?

What type of thermal material did you use between the CPU & heatsink? Are you sure you applied it correctly? Are you sure the heatsink is locked down securely?

"Your CPU is only running at 2.4GHz so you're actually

I have not done anything to intentionally lower the cpu speed. It
occasionally spikes to 3GHz but does usually remain around
2.4GHz. I imagine it is slower as a result of the high
temperature and low rpm.

I did try to replace the thermal paste on the stock HSF and
when that didnt work I bought the third party HSF and just
used the thermal paste that came with it.

I believe it is locked down securely...it is a pain in the butt to
get on.

Anyone have any idea if flashing the BIOS might help? I
looked at the revisions on ASUS's website, and one revision
says "Fix CPU Temperature abnormal when use E8000
Series CPU". I don't have an E8000, I have an older model
Pentium D 925 but this is the only thing I can think to try right
now. I have never flashed a BIOS before so I am reading up on
that...until then, anymore ideas?

think about your fan, is it giving it true put to dispose of the heat generated by ur CPU, if you have not look at the root cause of the problem and only looking for solutions then you are in the wrong place, first identify the problem, document, recovery procedures, provide method for testing, and diagnostic during observation,
treat each component separately, trust no one.
recommend possible solution procedures and document for future problem if they emerge.

The problem is NOT the BIOS. If anything, it's the heatsink installation. Here's the instructions for applying paste to a Pentium D:
