Series 7 NP700Z3AH Fan noise -abnormally loud?

[motherfo]

Something I forgot to ask previously: Is the HDD 5400 rpm or 7200 rpm? The latter tend to be slightly noisier. Also, how is the HDD fitted into the chassis? Is it metal to metal or are there any rubber pads?

7200rpm Hitachi. I'm starting to think this is the source of the problem.

I was referring to the temps you got with your own paste, which I assume is the mx-4 paste. I am a litte surprised because you get 78-81C with prime95 and my own readings (with mx-2) were around 91C after 10 minutes.

Yep. Arctic cooling mx-4. Great stuff. Cleaned with articlean first.

7200rpm Hitachi. I'm starting to think this is the source of the problem.

Try listening carefully close to the front left corner. The photo shows that the HDD is a tight fit in the chassis (no space for any rubber pads) which would help amplify any noise. The fan is blowing out the back which should reduce the fan noise slightly (depending on what you have behind the computer.
