Expand Post »

i appologize if this is in the wrong section. Lately my computer fan has been turning on and when it runs it is very loud. I let my copmuter sit over night and i turned it on and within 10 minutes the fan came on and is loud as can be.

Have you tried taking it out and cleaning off the dust? Blow it out with some air too.

Clean it!

I use a soft bristled, clean paint brush to dust off, then a plunger type camp mattress inflater to blow the dust out of the case. If the fan is still loud, try carefully peeling back the sticker, and applying a single drop of sewing machine oil to the tiny hole you'll see above the spindle. If that doesn't help - replace the fan as a matter of urgency.

I've had the same problem a couple of months ago.. a couple of bangs against the computer solved it though. I'll try cleaning my computer as well.

If that happens, it probably indicates a fan that's working its way forward on the bearing. If that's the case, the fan should be replaced anyway, because it'll fail sooner rather than later.

What are your computer stats? and if you know what motherboard you have, then the motherboard manufacturer ususally has a untility that lets you monitor system values like cpu temperature, fan speed, voltage etc.

If you're 'banging' your computer while it's running, you are probably damaging the platters in your hard drive!

Bearing wear is a problem with cheap DC fans, noise is a major symptom. Actually you can replace the fan yourself, based on the physical measurements and the current rating--it's pretty easy. Most are 80mm x 80 mm square x 25mm thick. This is a pretty typical power supply replacement fan. You may be able to find a similar one locally at a computer store or trade show.

Make sure the supply is unplugged for an hour or more before you open it to discharge the capacitors.

Does it really need to be this long? I thought that's why motherboards had those little lights on them-- to tell when the power in the system has been discharged.

Usually, all I do is unplug the system, and then hold the power button in for about 10 seconds, and then crack things open. Have I just been lucky up to this point? I've never been zapped, or anything...

That's fine for working on the inrenals of the system itself, Alex, but when you're cracking open the power supply unit itself it pays to be quite a bit more cautious. There's some rather big-ass capacitors inside power units!
