Does your fan have RPM Monitoring capability?  To tell, look at your power lead, and see if it has a yellow wire along with the red and black wires.  If that's the case, you should be able to see the RPM speed through Sandra, that is if your motherboard actually supports that kind of monitoring.
Usually, lower rotational speeds mean a hotter processor.  Regular case fans dont have the power to push the required amount of air through the heatsink.  If this fan is a case fan, you might want to reconsider buying a fan that's specifically made for a processor.  Put simply, get a fan that has a higher rotational speed, and you might be able to cool your system better.

Oh BTW, using a Tornado is nice on an Athlon XP chip, making a rheostat to control the speed is quite easy if you know how to solder.

is it possible the fan is just hitting a cable when it spins i've heard of that happening

Tornado is nice on any processor out there right now as long as there's a rheostat. Why can't people ditch the myth that AXPs run hot? If you want hot, go get a Socket 775 Prescott.

If you get a Tornado, get some sort of fan control method. You'll need it.

This motherboard has one, but I actually don't care much about fan noise as I always wear closed-ear headphones anyway. The processor fan I have right now is supposed to be pretty loud at 47dba, but I got used to it within a week of getting it and have had it for three years now.

Why do you people forget to clean your computers out once a month. All it takes is a can of compressed air, that you can get at any decent computer shop for $4.00 usd. ...that reminds me...

I normally do, it's just that I had missed the area between the fan and the heatsink since it's a chore to put the fan back on with the model I have. Bad idea in hindsight, but oh well.

Do you know how much these fan filters cost? What effect do they have on the fans' power?

[kasperl]

It is not 2cm radius, it might be just 3 cm diameter, but not more.

The fan is at 6600RPM, but it varies by about 200 RPM each time I check. The temp went down to 32 C today, which is about 10C above envirment temp. I can't set the RPM, only check it.

Anyway, new PC is on the way, I just configured it, paying only 250 euro myself, getting an AMD64 3k+, a gig of RAM, and a Radeon 9800 Pro.

its entirely possible, i had it happen a few times. some manufacturers do not like to ziptie everything together to keep such phenomena from occuring.

I agree, though those thoroughbreds run *hot* compared to the Bartons.

Another thing.. when wiggling around the HSF, did you possibly lose contact between the proc and die on the chip?  If you did, the thermal compound may be shot, which would need to be replaced for optimal cooling, but seeing as it's dropping again, the compound probably is working properly.  That is, if this could be causing any of the problem at all.

Actually, Thouroughbreds at the same clock speed produce less heat than Bartons (when both are stock). But the 68w put off by a 2700+ pales in comparison to the 103+ put off by a Prescott, and the 89w put off by a S939 or S940 Athlon 64.

No, I immediately cleared all the cables. Not that stupid.

[Flipside]

Being a smoker isn't condusive to keeping your computer fan free of gunk, I can testify to that. One of the reasons I'm trying to quit

[kasperl]

Don't smoke, but I can't say I vacuum this place every day either.

Because it's no myth. For their time they did run very hot. 50-55 degrees celcius is the normal operating temp. for those things.

just had to make sure, because, you know, that would be the most logical explanation

[kasperl]

First thing I did when I heared the noise was power down the PC, open up the case, and clear the cables another cm.

That would be the fault of the heatsink, then. Realistically, unless you're talking about Palaminos, the AXPs run cooler than their Intel competitors by about 10w.

Or just poor airflow in general.

My XP2800+ runs at 38C idle, and tops out at 49C full load.  Hell, at one time I got it down to 30C (I have a screenshot to prove this) just by opening the window at night (it was pretty cool outside....though the only reason I had the window open was because the motor on the A/C unit blew.).
