Heatsinker's driving me crazy

Since some days ago, I've noticed the CPU fan is spinning at the max speed (a bit higher than 5200RPM). In some very rare cases it deccelerates, but most of time it's flying.

The CPU and system zones are quite ok. The CPU fan is always at max, don't caring if the system is under high load or not.

I know I should replace my heatsinker with a better one (can you suggest a model? great), but is there something I can do in the meanwhile? I guess this is not a software issue, right? (last thing I've done at hardware-level with the PC: installed a video card).

The vibration is annoying. It's like a thousand of bees in my room. LOL!
 
Did you use thermal paste on the CPU or use the thermal pad that comes on the stock cooler? It sounds like you might not have good contact between the CPU and heatsink. Also, try using Speedfan to manually adjust fan speeds at different temps, just be careful not to set them too low and burn it. I wouldn't feel comfortable running a processor above 45C idle considering what it does to CPU life.

I'd recommend one of the Zalman 7000 or 7700 series coolers with AS5 paste myself. I'm very happy with mine.
 
You kind of have to tell us what board you have. ;)
 
I've used the stock cooler thermal paste. The machine was assembled about six months ago. This kind of problems are new.

Speedfan don't seems to change anything. Also, it makes hang my existing monitor program forever (requiring reboot).

I'm using an Intel D865GBF....

Everything is Intel here (they should give me a free t-shirt or something :D)

I will try to change the thermal paste first. Is there any special consideration? some FAQ about this? to scrap the CPU scares me....:(
 
i have this sorta old coolermaster fan from 2002 and it spins at 7000 rpm constantly, sounds like an airplane
 
Don't scrape the CPU to get the paste off!!

AS makes stuff to remove it, or use rubbing alcohol. Don't touch the pins. They bend easier than they look...

You may want to lap the HSF and\or CPU but personally, I think that's what thermal paste is for and it's unnecessary in most cases.

EDIT: Lapping is unnecessary in most cases, not thermal paste.
 
Ok, I will try to follow those COMPLEX instructions.

Hey Bastian, could you explain what you mean with "to lap"/"lapping"? sorry, I don't get it....English is not my mommy lang.

Just forgot it! time after install the video card, I had to replace the PSU, so THIS is the most recent hardware upgrade I've done on my PC. So I ask, could the new power have influence on the issue?
 
'Lapping' is basically sanding down the surfaces of the heatsink and\or processor that are designed to transfer heat such as the bottom of the heatsink assembly or the surface of the CPU.

As I said before, it's usually only necessary in the more rare situations where you can actually see or feel indentations, or worse, bumps in the surface of either. Some will say that it should always be done no matter what, but that's simply not true. If you can tell that your surfaces are smooth and can't find any irregularities in the metal then there's no need to do it.

I don't like the idea of scraping the labeling off my CPU anyway. Seems like it would kill any resale value that it might otherwire have retained...
