P4 3.0 Cpu cooling advice.

3k rpm is where the stock fan is supposed to run. You should compare the
bios temp and the windows monitoring temp immediately after a cold boot and
again after idling for a few minutes to see how close they are.

If the cpu is actually at 80C, it's probably because the hsf wasn't
installed properly. Remove it, scrape off the thermal pad with a plastic
knife to avoid scratching, use rubbing alcohol to get rid of the sticky
residue, and spread a paper-thin layer of thermal paste (the $2 Radio Shack
stuff will do if you don't have anything better lying around.) Carefully
remount the cooler and try again.

The stock cooler is usually adequate to 3ghz, but a good aftermarket cooler
like the Vantec Aeroflow ($24 shipped from <a rel="nofollow" style='text-decoration: none;' href="http://www.11cb.com" target="_blank">www.11cb.com</a>) will reduce temps
noticeably. There are reviews and comparisons of various models at

Literally paper thin? I spread mine with a razor blade as someone else
recommended and the layer is probably half that thick. Which is better? I
have a zalman flower and idle temps are around 48-54c. P4-3.06g.

As I write this I notice that the Core temp is 41C , system is 36C on
the stock HS/fan. I have put MSI core center in user mode with the fan
turned up to full. Its OK now whilst I'm doing little, but when I push
yje CPU, say when I'm rendering Digital video. It still pops up to
70C+, I've ordered a Vantec Aeroflow, hopefully this will improve
things a little.

I'm using the Aeroflow on my 3.06 and am very pleased with the
results. Not only improved cooling, but it cut the fan noise by 75%. The
stock cpu fan sounded like a 737 ready for takeoff when under a load.
However, installing the Vantec/Aeroflow heatsink wasn't the easiest on my
GigaByte mobo. Had a hell of a time with the lockdown clips.

Temp seems high to me at idle. I have the same motherboard and a P4
2.4C clocked at 3.0 stock heat sink and fan. My idle temp is 30c.
What kind of case? number and size case fans?
Does taking the side panel off lower the cpu temp?
I found case ventilation makes a big difference. My case came with 2
120mm fans. Had to cut out the perforated metal where the fans are to
get good air flow.
I don't think the system temp sensor on that motherboard is accurate.
Mine shows the system temp higher than the cpu temp. That can't be.
The temp of the air blowing out the exhaust fan is the same temp as
the cpu at idle.

Just some things to think about.

My mainboard shows two temps; sys temp and CPU temp. (DFI LanParty 875Pro)
When i am running some heavy stuff, the CPU is 49 degrees, the sys temp is
41. When i go to idle, the CPU quickly goes to 31 degrees, while the sys
temp stays around 34.

I think the sys temp is the temp of the northbridge, which is passively
cooled. This makes it less hard to believe the temps are accurate, i
think...

The problem seems to be in what the expectations are for that temp sensor: as in
what one thinks it should be/is monitoring.

I just installed the Vantec yesterday and have noticed a 8-10.f drop in the
cpu and little fan noise.
Go for it.

Tony,
Take a look at <a rel="nofollow" style='text-decoration: none;' href="http://mbm.livewiredev.com/" target="_blank">http://mbm.livewiredev.com/</a>

I have been running Mother Board Moniter for several months and use it to
keep track of my liquid cooled CPU set up
(http://www.nathanlandry.com/LiquidCool)

Remember to use individual temp measurements mainly for before/after
comparison, rather than absolute figures for comparisons between other
people's boards. There are often claims of very high or very low temps.

The very high temps can be caused by miss-seating of the heatsink,
but very low temps can come from having a cold room or simply the
variations between motherboard sensors. A 10% tolerance is not that
unreasonable, and a tiny but finite percentage of boards may be 15-20%.

So for the same 36oC actual temperature, one could read 40oC re +10%
over, and the extremely rare 20% error board could be read it as 29oC.


Where MBM is excellent is comparing various changes to a cooling
system, such as using intake wire-grills to replace a restrictive intake,
or rerouting cables - often forgotten but can be a big help.
