CPU overheating issue

You may have to clean and re apply the thermal paste on the CPU. Check out NewEGG.com on YoutTube on how to do it right.
Done that twice over - the second link is the paste before I've clipped the heatsink on, not too thick, but with a large and consistent surface area. I think.
What thermal paste are you using? I see the processor is an AMD, what series? It may not apply to your situation, but here is a link that might help. http://www.arcticsilver.com/amd_appl...n_method.html#
Spire 420 thermal paste, came with the new heatsink. Also, the heatsink specs are http://www.spire-corp.com/main/produ...sp?ProdID=1140 , the CPU is a fairly oldish Athlon x2 dual core at 2.1Ghz. Anyway, I've reapplied the thermal paste again, much thinner this time, and it helped a bit. What's the generally "safe" temperature range for a CPU to work in, anyway?
What kind of temps are you getting now? I would try to keep max temp well below 60C under full load
for best performance, of course temps will vary per cpu.
It easily hits the seventies when the CPU usage gets intensive, but I'm asking more from the damage prevention aspect.
Something that just occurred to me - the heatsink clips in to place rather easily, without much pressure needed. Could that be the problem? There are little "rungs" on each side of the clip, should I try to move each side by a step so as to put more pressure with the clipped sink, or would that risk punching the CPU through the motherboard?
There should definitely be some pressure involved but just enough to keep it evenly and firmly seated.
Also the layer of thermal paste should be very thin. Basically all it is supposed to do is fill in the micro pits the two surfaces. It should be more of a film than a coating. If you use too much it acts as an insulator rather than a conductor.
Don't count your weasels before they pop dink!
Did that, didn't help much. Is there a functional difference between applying the paste on the heatsink or the chip itself? I'm guessing not, but I've reached the "no stupid questions" point.
That's a pretty old MB if its socket AM2. The CPU might be just showing signs of age.
It looks like there is too much thermal paste on there. Have you tried sticking the old one back on and seeing if you have any issues? Its possible the newer one isn't cutting the mustard.

i have always said with thermal paste less is more,as thin as a layer as possible.

1) There shoud be pressure. Positive pressure upon the CPU/cooler to keep a good contact beween the surfaces. Most motherboards bend under the pressure, these days, in fact. It's rather alarming the first time you see it...
2) You need a *small* amount of the goop. Spreading it with a business card is a good idea, just a thin amount on the CPU itself, and a clean surface of the cooler. You have entirely too much on that cpu, if you ask me, in the second picture.
3) You said the cooler has a 3 pin connector... and that connector is put where... on the motherboard? It's possible that the motherboard can't compensate correctly, or fast enough, with a non-stock cooler. You may need to use a separate temperature controller or a manual fan controller to fix this issue, unless you can get Speedfan to run those fans directly, and then set it to ramp the fans up faster/sooner.
Exceptin' those, there shouldn't be any issues, so if you do all that, including just simply running the cooler fan at 'screaming', and the temps aren't good, the cpu is probably trash, or the sensors are.
/Like the Gigabyte brand, exclusive to them for my own personal needs... but haven't been an AMD fan in years... Temps are one of the reasons.

Alright, so... I've got an overheating CPU problem.
A quick rundown... replaced my old and grindy CPU fan with a new one... except when the CPU runs at full or near capacity {for example, when running, oh, a game of some sort}, the temperature gradually creeps up, and keeps creeping up indefinitely - or until the CPU starts screaming in pre-shutdown agony.
Stuff that might bear mentioning;
The fan only has three connector pins instead of four. However, since it came with the heatsink itself, I assumed it shouldn't be a problem.
The specs on the box say that it should go up to ~3K RPM, but SpeedFan never reported it going more than 2K-ish.
Once the CPU eases off, the temperature quickly drops back into fifties and gradually down into upper thirties.
There's a consistent layer of thermal paste across the chip. There's a bit of horizontal wiggle room with the heatsink clipped in place, but it seems to fit snugly against the chip anyway.

Any ideas? This constant game of "I'm not touching youuuuu!" is starting to get on my nerves.
