very LOUD computer...

**Axegrinder** · #1 4th Mar 2008, 02:19 PM

Hi all.

I bought a pc off a mate of mine, just as a computer to experiment with, turned it on and it was incredibly loud...the only fans on it are the psu fan and the cpu fan.

Specs are:

Pentium 4 1.5ghz (skt 478)
608mb of ram
Gigabyte GA-8SIMLH mobo
2x 20GB hard drives (Western digital and seagate)
Windows XP.

And the question is?

It gets on my nerves after a short while. Also i forgot to put there is a slight grinding noise coming from somwhere, but the noise is so loud it makes it hard to dtermine which fan it is.

Pull 'em both. Clean and re-install.

it may not even be a fan. try taking them off the power, and see if you hear the noise or not. if you still hear it, it's likely from a cd-drive or a hard drive.

if you don't hear it, then it's one or the other. and from there you just plug one or the other in. not hard to figure out.

Also would you think the psu is working overtime? Its is only 250w after all.

**redden137** · #7 4th Mar 2008, 02:58 PM

clean the fans as much as you can see if it makes any difference,
if the noise level stays the same even after windows has booted up and youve left it for 5 mins id say it prob is the psu

I did clean the cpu heatsink/fan, as there was alot of dust buildup, yet it was still horribly noisy.

**redden137** · #9 4th Mar 2008, 03:16 PM

some p4 fans are on start up
did you get to hear the psu?

The bearings go too, if it is one of the fans just replace it.

**kanoakavirus** · #11 4th Mar 2008, 05:37 PM

try putting oil in the bearings for an inexpensive quick fix

if its only the 2 fans, and there annoying you that much, just replace them with low noise fans.

**kanoakavirus** · #13 5th Mar 2008, 05:47 AM

What does it sound like? grinding, vibrating, or sorta like a hoover?

**DanBex** · #14 5th Mar 2008, 05:50 AM

he said above theres a slight grinding noise coming from somewhere lol.

Hi all.

I replaced the 250w psu with a 400w psu today. And there was a slight grinding noise when booting but that dissapeared aftter a few seconds, the computer is still rather noisy so i presume the cpu fan is to blame.

Temps are:

Mobo 31c
CPU 32c
CPU fan speed 5273 rpm (too fast?)
