cpu over heating

[Guest]

i can see that there could be lots of reasons why a cpu could be overheating
first it was because the fan was not pushed in all the way
but now i cant guess at what to do
am using the intel pentium 4 processor 520, 2.8ghz the one that comes with a
fan
and my power supply is an atx 12v true power supply with 380 watts
and i have another low speed 120mm fan that meets intels 3ghx system cooling
standards
so, ...maybe i need a bigger power supply any suggestions would be helpful

Is the fan running? You say overheating, what makes you say overheating?
So is this a new PC you built? Maybe a little info, because this sounds
like we just walked into the room, and we hear you talking to yourself.

Your power supply should be ok! How is the extra fan air-flow oriented?

On AMD processors at least the fan is fixed/screwed to the heatsink so "the
fan was not pushed in all the way" does not compute.

If the heatsink and heatsink compound/label isn't installed exactly right it
will overheat.

Presumably you can see the fan going round?

 

[CWatters]

Was there a "heatsink compound label" on the heatsink? Was there a film
cover over this label and did you remove it?

You don't need a larger power supply. There are several possible
reasons for your CPU overheating.

1) Fan on the CPU heatsink is not running.
2) Fan or heatsink or both are inadequate for the requirements.
3) Thermal paste has been improperly applied between the heatsink
and CPU.
4) Interior case temperature is too high.
5) CPU is overclocked.

In your case, I'd guess it's either that the fan isn't running, or
the thermal paste was either badly applied, or omitted entirely.

I'm interested in hearing the replies you get. I am fighting the same
problem. My system is using a P4 2.8ghz/PC800 processor. It freezes at
about 54 degrees C. I purchased a high efficiency copper heatsink and fan
and it brought the temp down about 3 degrees over the stock heatsink but if
I try hard, I can still get the temp up to 54C. It idles at 38C.

The program that I use to monitor the temps can be found here:

In your case it sounds like not moveing the hot air out of the box, or
air circulation blockage around the CPU.
