If you have a computer fan that sounds like the bearing has been replaced with gravel, there may actually be a simple fix. All you need is a screw driver, a small pick, and some lubricant. In this instructable, I repair my GPU fan. However, the process should be nearly identical for any fan in your PC.

Step 1: Remove Fan

I repaired my GPU fan. First, find the screws holding the fan in place, and remove them so that you can access both sides of the fan freely. Now is a good time to clean up all the dust that's been collecting around the fan. Some canned air will work nicely.
<p>Hello! Many thanks for these tutorials! I have one more question. What can be the cause of noisy fan. I have just bought new fan to my PC (http://hardware.be/power-supply/dell/450-18455.html) and when I turn on computer I hear crazy sound. What it can be! CAn it be problem with fan or maybe unsuccesful replacement of it?</p>
<p>What if there is nothing exposed other than the fan housing when you remove the sticker? Then you need to head on over to my new article. </p><p>http://www.instructables.com/id/Noisy-Computer-Fan-Repair/</p>
What to do if there is no split ring?
There should be some kind of clip holding the axle in place.
Thanks for this instructable. I'm doing <a href="http://nexedgeaz.com" rel="nofollow">computer repair in Chandler AZ</a> and the fans are one thing that I have hardest time with. Thanks again.
Thanks for sharing this. We've been looking into someone who can do <a href="http://abstechnologies.net/" rel="nofollow">computer repair in Taunton</a>. But now that I think about it, it would be really nice and a lot cheaper to do it myself. Thanks for the help.
Great instructable! My laptop seems to suck up everything in its wake, and I have to disassemble my fan once every few months, no matter how careful I am. I was really nervous the first time, but I couldn't afford real <a href="http://nexedgeaz.com" rel="nofollow">computer repair</a> help, so I had a friend walk me through it. Now, I use this process all of the time. I'm sending this on to a few friends. You're able to break it down much more easily than I can.
Thanks for sharing your info. I enjoyed reading your article. Have a great day. <br><a href="http://www.promotionalcanvasbags.com.au/" rel="nofollow">Wholesale Cotton Bags</a> <br>
Great tutorial. Very helpful. My GPU Cooler works like new. Thanks
would sewing maching lube work too?
If you can get in there and wipe the crud out the bearing, it works that much better.<br />
&nbsp;Awesome to see someone else that figured out how to open computer fans right up!
great instructable! my servers cpu fan sounds like theres a gun fight goin on inside my pc lol
That would be awesome! :D<br />
or it could be all the dust mites having a nuclear war in there :O
you should also blast the "fins" with compressed air to get the dust off
For that I useubbing alcohol.
thanks for this. i had a slow fan on a drive enclosure and the tip to take off the sticker was the one that set me up. thanks a lot.
You can also use sewing machine oil on a Q-tip.But use no more than one drop for each part.Shaft gets one drop with Q-tip and bearing gets one drop straight from the bottle.
Use grease instead of oil and it'll last longer
Actually for computer fans oil would work better. In all reality, most computer fans will never really need any sort of lubrication. I've re-oiled the fans on my computer that runs 24/7 only once in the past 3 years
I've used oil and oil and oil and then switched to grease and never had to re-do them.
wow, how old and how often is your computer on?
My computer started with a 486 and its been upgraded a part here and a part there for 15 or so years. I think the floppy is still original. :P
correct: how to repair most GPU fans... any idea on normal,cpu or power supply fans?they sound like 7 years old vacuums(not pc's)...
The process should be nearly identical for any fan in your PC. Just remove the fan, remove the sticker, remove the split ring, lubricate, and reassemble.
thanks for reply
