P4 CPU upgrade lets fan rev up!
I just sucessfully upgraded my stock 3 GHz system with a 3.8 GHz (2Mb cache/64-bit). The machine started right up, didn't even halt for the BIOS to show the new processor data. And in the Windows Performance rating the cpu is now as fast as the memory (4.5) and not the only bottleneck anymore.
BUT with that came an annoying issue: the big main fan that also cools the heat sink runs at a much higher rpm level now. I used arctic silver thermal paste between cpu and heat sink and I am sure I did that right. The old cpu had some crappy old paste on it that forsure didn't do a better job.
Could it be that the new cpu is running at a higher temperature level triggering the fan to rev higher? Or could anything be wrong with the cpu? I got it used on ebay from a trustworthy seller, it was used but tested and has a 1 year warranty.
The only thing I could think of was resetting the BIOS by removing the cmos battery in hopes that this would kinda recalibrate the fan control, but to no avail. That said I don't see any chance to modify the fan rpm level through the BIOS, it has no such settings whatsoever.
Oh and should you propose next thing to do for me is getting a program to measure the actual cpu temp: so far there is none out there that is able to handle P4 cpu's due to their missing digital thermal sensor. I had just gone through that recently even being in contact with some of the developers. They keep working on it but would not want to raise my hopes.
Any other ideas....? I would be bummed if I had to go back to the 3GHz just because of that!
