9800 Pro Overheating CPU?

Can somebody help me out? I'm sure this is a bit OT but here goes:

I have a P4 2.5G, Asus MoBo (P4T533-C) with 512M RIMM 1066, No
Overclocking, Intel Fan and cooler on the P4, an extra 8cm case fan and a
dual fan Power Supply (400W).

Used to have a Geforce 4 Ti 4400, just bought a 9800 Pro, delighted with the
improvement but...

My CPU now overheats quite a bit when I'm playing games: Unreal II or F1C
can take it to around 60 degrees Celcius (140 Farenheit). Im am sure this is
not a case of the 9800 overheating (this is why I say the post is a bit OT)
because: 1-the9800 cooler is never too hot to touch and 2-the Motherboard
doesn't heat much, it stays at around 42 degrees Celcius (108 Farenheit).

I've tried to readjust the coupling between the fan/heatsink and the CPU and
it did not improve. I've checked the 3.3, 5 and 12V tensions and they are
within limits, the PC can be on for hours with the CPU temp around 43C, as
soon as I fire up Unreal II here comes the heat.

As I see it, the GF4 did not cause any probs because it was "slower" than
the CPU and the P4 had to sort of "wait" for it, the 9800 Pro is a rocket
and pulls the CPU to the limits.

Any suggestions? is 60C (140F) acceptable? Intel says the P4s perform an
auto-shutdown at 80C, this has actually happened to me a couple of times,
its probably better now with the readjustment in the heatsink but 60C???
(shoud I worry?).

TIA

60 should be OK, but you'd probably feel better if it was around 55 or less.
The one case fan you have, where is it and how is it blowing? For one fan
I'd have it in the rear blowing hot air out. For a second fan, in the front
blowing in.

One thing, while adjusting settings in the BIOS your CPU is at 100% load (no
idling), so leave it on the temperature screen for a while and see how hot
it gets when the video card isn't doing anything.

A max temp of 60C is nothing to worry about on a P4, and Unreal II will push
any card and cpu to the hot end of the spectrum. I can run my modded and
overclocked Radeon 9500/9700 to 330/297 in any other game. It will lock up
after an hour or two of U2 at anything above 325/290.
 
The Radeon is actually cooler than the GeForce FX 5900, so I doubt it's
the cause.

One case fan is not so great really. Two exhaust fans would better. A
front fan won't cool a case as well as a rear one will, because it really
won't change airflow comming out of the case. I have 5 fans on my case
currently, and my Athlon 2400 gets up to about 42 degrees maximum. 60
dergrees is probably OK for a Pentium IV, though, although it'd be great if
it were at least 5 degrees cooler. The components inside are no doubt
getting warmer and will shortern their lifespans theoretically, but if this
is worth it is hard to tell because you could be just shortening them from
10 years to 5 years, etc., which really won't matter.

Another option would be to replace the fan with a high airflow fan, but
then you are looking at alot more noise.

I have a GF4 and noticed similar behavior, so it's not just
the 9800Pro doing it. It seems that, when sitting at the Windows
desktop, the CPU is idle most of the time, so the CPU temp stays low.
With any app or game that significant increases the processor load,
the CPU is busier and generates more heat. So the CPU is probably the
culprit, and not the video card. If the video card was generating too
much heat, then there would a general increase in the temperature
inside the case, which should show up as an increase in the
motherboard temperature.

60 C is probably not too outrageous (or at least I hope not,
since my 2.8 GHz CPU also approaches that temp at full load). What's
more worrisome, though, is if you're hitting the temp where the CPU is
shutting down. The CPU shouldn't be running that hot, so you may need
a better CPU cooler.

BTW, I'm seriously considering the exact same upgrade (4400 =>
9800Pro) and was curious how significant the improvement was. Is it
pretty noticeable during gameplay, or just with benchmarks? Is the
difference just appreciable at higher resolutions or in newer games?
I'd like to be able to easily notice that I have a newer video card if
I spend over $300 on it. Thanks for any advice you can give.

After I swapped my GF4 Ti4200 to a 9800pro my mb temps went up about 6
degrees celcius. The 9800pro does run hot compared to a GF4. But it is
still well within the safe limit. My cpu is idle at 38cel and mb about
34cel. My mb temp used to be 28 at idle with the GF4 and same cpu. I
guess if I had a GF4 Ti4600 it may have been closer to the 9800pro
temps though.
 
Thanks for the tips guys. I replaced the Intel Heatsink and Fan for a
new one (Thermaltake with adjustable fan speed) Keeping the fan at
6000 rpm got the temperatures down quite a bit (a bit noisy
though...).

As for the question bellow: In my case changing from a 4400 to a 9800
Pro allowed me start using 2xAA and Anisotropic Filtering making the
games look much better. I still run all my games (FPS and Sims only)
at 1280x1024x32 @75Hz.

The improvement in quality was fantastic with EA Sports Sims (F1 2000,
F1C) and Unreal II, in both cases frame rates improved a bit also.

In Nascar Season 2003 the image looks better but the frame rates went
down slightly (from 90s to 80s).

I've never done a benchmark so I don't have exact figures.

I don't regret spending the money ($400 in my case) but I am a
stickler for image quality, specially in driving games.

Hope this helps.

Same here with the temperature rise from GF4 Ti4200. I didn't think
ATI cards made more heat.
