Sometimes more of a buzz

Even so, it is horrible and I want it to stop.

I cleaned out the dust as best I can, but how do I clean a computer fan and rebalance it?

    Are you talking about the CPU heatsinkfan, case fans, or the power-supply fans? Is this a custom rig, Or from a place like Dell or Gateway?

    With case fans you'll want to use short bursts of compressed air with the can held upright and make sure all case fans are secure in their housings. If the clicking persists might be time to spend $20-$30 (depending on how many and the quality) and just get some new case fans.

    If it is the CPU heat-sink-fan, you can also used compressed air to ensure there isn't dust obstructing its normal operation, but if the fan is properly secured to the CPU fan housing and devoid of dust and random shit you either have to get a new hsf, or if the computer is still under warranty, send it in and have the manufacturer take care of it.

    If it is the power supply fan, you can either return it to the manufacturer for repair if its under warranty or still within its RMA period. Or buy a new one and toss it in yourself.

    If it is an old comp, no longer under warranty and you feel comfortable enough, you get can hsf combos pretty cheap online for some decent gear and then install it yourself. If you are not comfortable, and don't know anyone you trust to do it for you, I suppose you could take it to a PC repair shop and have them perform the work. I don't like to suggest this route as my personal experiences and those from friends and associates of mine have been negative in regards to service and pricing, but this is just my experience and you might have a grand old time with this route.

    Two more things, turning the comp off, unplugging it, after using compressed air, you can lightly tap on the center of the fan mechanism. You might knock the fan back into place if it is off kilter. Though, with time and more usage, it's pretty likely whatever fan is doing this will jostle loose again due to vibrations. As well, if this is a custom rig with custom HSF and you or someone that built it for you has tinkered with the RPMs of the cpu fan, you might check into the manufacture recommend speed setting for the type of use this rig gets, and then go into bios and either speed it up or slow it down, based on what they recommend. If you are not familiar with this or worried about changing a setting you shouldn't, I'd let someone who knows what they are doing perform this for you.


    As for re-balancing the fan, I have no solid experience with this, and, for the most part, just replace parts that are acting up.

    Is there a wire leaning against it? When you put the side of your case on, it might be pushing a wire into the fan. When you open it up you won't see it. Runt he computer while the case is open and see if you can physically see anything near the fan.

    I am very very very sure it is the PSU fan.

    No easy way about this huh.

    Also my case has a clear side so I can tell there are no wires :P

    Well, the easiest thing would be to replace / RMA the power supply then.

    If you want to try and solve things yourself, and think that maybe the fan just might be a little rigid or dusty, I highly recommend trying to oil it yourself. Go to the grocery store and grab yourself a can of 3-in-1 oil (DO NOT use WD40 for this!) and then try to oil the fan by peeling back the sticker on the offending fan and adding a drop of oil. There's a good tutorial here. I've used this trick on case fans before, but never a CPU fan. It still might work.

    It's a bad bearing in the fan motor, and nothing you do will fix it. Replace it if you hate the noise, or just let it die and replace it then.


    First google result on 'fan bearing' has some decent info if you care.

    Disclaimer: You probably don't want to do this. I have, and didn't die, for reasons that haven't been adequately explored.

    Aside from dremeling off a big hunk of my PSU's case so my DVD drive could extend INTO the PSU and actually fit in the computer, I removed the fan from mine because where it was sitting it was expelling air directly into a case wall (also I wanted to use it elsewhere). It had a totally standard snap-off power connector. All the screws involved were Philips head. If it's a bad fan that's making the noise, it's terribly easy to take it out.

    Just, you know, MAKE SURE IT'S UNPLUGGED BEFORE YOU TRY ANYTHING LIKE THAT IF INDEED YOU WOULD DO SO.

    The thing about a PSU is that it still holds a considerable charge even when unplugged. It's those round thingys (capacitors). But yes, feel free to take it apart and check. Just be mindful.


    Related - I saw a similar issue last week. when I opened the PSU open to check the fan, I noticed that a few of the capacitors were swollen and one was leaking. Probably due to overheating because of the fan not working correctly. If you see anything similar forget the fan and replace the whole thing. I got one off newegg for $45 with shipping.

    That's capacitor plague. But you're right, a bad fan will accelerate the problem.
