Hi,

I got my computer back and it seems that it's very noisy (it was that way when I got it the first time anyay) . I've got a Coolermaster case for it, but yet, the fan seems quite loud and the temperature of the CPU is about 51 degrees.

What temperature should it ideally be and what can I do to reduce the fan noise?

Thanks

Temp depends on the cpu, some run hotter than others, is 51 deg idle or under load?

Do you have any case fans or just the cpu fan?

Get some compressed air and give the case + fans a good clean out (I recommend doing this outside as it can be a bit dustier than you expect) zip ties are also good things, clean up the cables a little so you get better air flow.

got it back from where?? a repair shop ? Oh yes, I remember fans clogged heavily right? That may have actuall damaged the bearings in your CPU cooler.
open the case with power on-- try to determine what is making that noise. if it's the heatsink fan-- you should replace the heatsink.

try this, take the little sticker off hte cover of the CPU cooling fan, there should be some motor bearings visible. spray a little 3-in-1 oil, or soem WD40 in it, use only A DROP. it should help loosen up the bearings.

You might be best taking the CPU fan off before doing that as I don't imagine over spray would be too good for the components.

I don't think I would be the best person to do that (taking the computer apart etc)

I think it could be a case problem? What do you think, is that a possibility?

You need not fear opening your case--having the shop do it for minor problems is expensive/time-consuming...unless it is still under warranty.

Fan noise is an easy fix-- usually.(as long as it's not the PSU-fan) It can be anything from a failing CPU fan, to a wire dangling in it as it spins, to an incorrectly positioned wire-tie. With a Coolermaster case I doubt it's a case problem-- even if it's a noisy case-fan... they are mounted internally.

If you just got this back from the shop-- call them and ask them why it's still noisy-- I would not deal with a shop that would not suggest a fan-replacement when it is noisy already.If your CPU fan fails-- you could fry your processor. Ditto the PSU...It needs to be investigated. It is perfectly safe to run a PC with the cover off --with common sense of course-- to observe what is going on. You need to be able to do this --to clean-out the dust once in a while.

The pics in this tutorial can help you with part ID/what the inside looks like.
