I'm having a tough time keeping the temp on my CPU down. System is a P4 3.40
LGA775 - 2 SATA drives - 2G RAM GeForce 7600/512 video card - no
overclocking. Mobo is Intel 915GAV

I have 4 case fans, 600W PS fan and Arctic Cooler heatsink with fan.
Actually system is fairly quiet. Processor idles at 60C - mobo at about 38C.
If I run an application like MS FlightSimulator which uses 100% processor
time - temp goes up to 73 - 76C and mobo stays around 40C. I've replaced the
heatsink - cleaned both the processor and the sink - use Arctic Silver 5 as
directed and just can't get the temp down. Other than noticing the temp, it
doesn't seem to affect anything but I imagine it's shortening the life of
the CPU. BTW, I ran Intel system monitor and Speedfan and they agree.

Should I really be concerned and what else can I try? Any recommendations on
a better heatsink solutions?

Thanx,

I also have high temperature with Pentium Prescott. It goes above 70 Celsius
lately, which is above design temperature. However, the system has been
running for 2 years now without any problems... In practice it doesn't seem
to matter too much if temperature is a bit high. Never heard of a blown up
processor because of heat.
 
Heat is what kills the processor over time. Higher the temperature, the
shorter the life expectancy. The only question is will it quit before
you are done using it.
 
something I try is to use Task Manager and reduce the priorityof the offending program.

does not always work, but worth a try.

Make sure that all cables are secured and out of the way.
Be sure each fan is working to move air in and out of the
case and not work against each other. Generally you'll draw
air in at the front lower area and exhaust it out the top
rear. You may need some baffles or internal ducts to be
sure the air is not forming an eddy at the CPU.

If you have a sheet of clear plastic and some "smoke" you
can watch the air-flow pattern inside the case. Be sure the
room air temperature and space around the computer is not
obstructed,

If all that is correct, you might consider switching to a
water cooling system.

Hello Vic
Joined a bit late but I have these sites in a saved folder - used them to
help build current system - hope they help. But a chap with your experience
has probably already come across them.

http://www.pcworld.com/article/id,122111-page,1/article.html

http://www.nonoise.org/resource/pcnoise/poweroid/poweroid.htm

The above were the only two sites out of a dozen or more that I could
understand ;-)

Check out these Prescott cases with the CPU vents.

<http://www.newegg.com/Product/Produ...t+case&Submit=ENE&N=0&Ntk=all&Go.x=11&Go.y=35>

These vents obstruct the heat from the GPU (video card)
 
A bit of progress - actually a combination of suggestions. Changed the air
direction in one of the fans, rerouted cables and now it operates within
spec. At full load it varies between 68C and 71C - that's a 4C improvement.
However the system temp has increased to 42C under full load.

I ordered a Thermaltake liquid cooler - may be the easiest way to go.

Thanx for the help!

Hello Vic
That still seems way too hot for my liking - liquid cooling seems
over-kill - if it goes wrong you will need a good plumber :-).
I remember reading, in a couple of gaming forums, where leakage has caused
havoc - something to consider perhaps.
Looking at your case from the front elevation, do you have a circular inlet
in the left side, about two thirds up and a couple of inches from the back?
On my case, this is the removable side panel - attached on the inside is a
tube which sits about 1/2 inch from the GPU fan when the panel is in place.
I selected this case re the inlet being juxtaposed to the CPU fan.

This is the only intake on my case - the fan is a 120mm gig. ultra-silent
runner(that in itself is a misuse of the English language).
In hindsight, I think I should have got the retail version P4 which had its
own fan/sink.
A friend has a P4 3.2 with no extra fans and that runs cooler than mine.
I have a single 80mm rear extract fan(which makes more noise than anything
else). I have a 650 power unit with a single 120mm fan(did have same with 2
X 80 but was no use whatsoever-that ran hot in itself).
With two different monitoring softwares, used over the past 6 months, at
high usage running FS2002/2004, the temp CPU peaks at 45-48c.
Using a very sensitive scientific heat probe inside the case I get a lower
reading???? in front of the small rear case extract fan, which is mounted in
line with the CPU fan. The power unit is just above - all three cannot be
more than 3-4 inches from each other.
I have the P4 (650) - 64 bit ready - LGA775 etc etc - prob same as yours.
I have no other fans - now if you had said you had a 478pin Prescott, which
I had previously, then I would expect 65-70c which I used to get, playing
patience.
Hope this helps in some small way

You're welcome. You'll be happy with the coolness and quiet
of the liquid cooled machine.
