Computer keeps going really loud

This morning my computer seems to be much louder than normal. It sounds like a fan, and seems to be the one in the power supply.

It is a constant drone, then stops for a few seconds, then starts again.

What are you temps like?

timmillwood · 10 Aug 2011 at 10:28

Temps are really low.
CPU 29c
Motherboard 27c

All I am doing list listening to music and copying files over network.

Wonder if it could do with a clean or something? It's only a month old though. If I suck the vacuum nossle in the psu fan hole would it do any harm?

Naa i always hoover my fans...i have a dusty room lol. Same happened to me last week. Fans were mega loud. Now they are normal.....strange

Dont shout at me for suggesting this, but you havn't left a DVD in the drive have you as these will tend to spin up now and then and can sound like noisy fans?

Maybe ambient room temperature is higher so fans working harder to keep that cool?

I don't have a DVD drive

CD or Blu-Ray drive?

There might be some surface dust on the pc, you could use a small new (clean) paintbrush and some compressed air to give the whole thing a decent clean. I wouldn't recommend dismantling the PSU, but you can blow air into it.

It's possible it's got a defective fan or you've got dirt in the bearings or something.

Similar thing is happening to one of my graphics cards, but I'm too lazy to do anything about it.

I'd RMA if it happened with something that's only a month old.

Same happened to me, I had to kick my computer to level the fan. Not the most sophisticated way, but it worked. If that doesn't work, get some anti static lube for the fan, take it off and give if a thin layer. I went and bought thermaltake hydro brearings and they are quiet as a mouse. Noctua do a really good silent fan too. You might end up spending about £20 on fans if you replace the whole case, but it's worth it.

Open the case up, clean everything out. If you can still hear it, find out what fan it is. Push down on the middle of the fan to stop it, if the sound continues, then it's not that fan, try another one.
