I just recently rebuilt an old computer. The new case had a couple of extra fan slots, so I took some fans from an old power supply... problem was that they were filthy.

I discovered that disassembling them for detailed cleaning was a snap. I had two, so I filmed the second one using my new overhead camera jig.

 Don't know if anyone still reads this, but what type of grease did you use? and how often should you "change the oil" in it?
I can't say nothing but <strong>WOW!</strong><br/>Well, a few words more: thanks to this Instructable I feel pretty dumb now. I had a problem with a PC fan and I unmount it but I've never been brave enough to really disassemble it.<br/>Actually I never thought to remove the so-called &quot;dust seal&quot; (never seen that logo sticker as a &quot;dust seal&quot; actually) so I've never been able to notice the so-called &quot;retaining washer&quot;.<br/>So, as I was saying, I feel pretty dumb thanks to this instructable, because cleaning a PC fan like this is really an EASY task to accomplish. At least my fan is twisting again as new! :-)<br/>Thanks, klee27x!<br/>
I'm glad I could help! "...but I've never been brave enough to really disassemble it." - Having old, broken, and/or redundant stuff is the best way to overcome that hurdle. For instance, it's amazing how much I have learned about DIY car repair now that I have a second mode of transportation. Before that, I was stuck handing over my wallet to the experts. :)
Getting that retaining clip out is a pain and sometimes they break, I just stuff some grease in behind the rubber seal and it works its way in while spinning.
just wash it with water without disassembly, let it dry and it's inished!
Well, I suppose that's fine if it works for you. I wouldn't do it, because any water that gets inside the motor housing is going to stick around for a very, very long time. On a fan that is this dirty, relubing the bearing is also not a bad idea in and of itself.
that's alot like changing your oil without changing the filter, yes, its easier, but it's going to cause problems in the long run.
what is a running rap?
Oops. Supposed to read "running tap."
