How-To Quiet Noisy Case/PSU Fans

Do your case and/or PSU fans suddenly become noisy when you turn on your PC and do they eventually quiet down, in most cases, the fan is not going bad, just a little TLC is needed.

This quick guide will show you how to quiet down those noisy fans.

Tools needed;
1. Phillips head screwdriver
2. Exacto or Utility knife
3. One small bottle of;

Yes, it's gun oil and it works great with no harm to the fan and it only costs a couple bucks.
WD40 is not recommended.

1. Remove the noisy little bugger from the case and clean off any dirt/dust.


2. Place the fan on your work space with the label side up;


3. With the exacto or utility knife carefully peel back the label, (don't have to remove it completely) til the center is exposed.


4. Carefully place 1 (one) tiny drop of the RemOil where indicated by the arrow.
5. Replace the label, place it back in the PC and your done.

The PSU fans, a little more involved, but the same process as above.
The PSU has 2 parts, 1st part is the base, where all the components/board are attached, the 2nd part are the sides and top (1 piece).
1. Remove the PSU from the PC case.
2. Remove the 4 small Phillips head screws and carefully slide the case up to expose the inside to access the fan
3. If it only has 1 fan, then it's most likely hard wired to the board, (2 fans, one can be unplugged) so remove the 2 or 4 screws holding it in place and proceed with the above steps.
4. Put it all back together and fire up your machine.

Your fans should now be completely quiet, maybe even quieter than before.

Just a couple of additions.

1. don't do it if your pc has been security sealed as part of a warranty package, ask the warranty folk first as it will be considered tampering.
2. regular clearing of dust externally with a vaccum cleaner can also prevent issues.

Be careful with the vacuum cleaner, it can sometimes discharged static electricity and fry you components. There's plenty of horror stories out there about it.

Ditto, ya beat me to it bassfisher6522.

The tip was also not intended for new PC's.

True but you wouldn't get a static charge from sucking the dust out externally as the case is earthed... obviously for people that open the case up, use a can of specialist air duster to blow the dust out, making sure you wear a mask as can be nasty to inhale.

used a blow dryer with no heat to blow dust out, goes everywhere (outside) those little aeosol cans get into nooks and crannies nicely tho, tried 3 in 1 oil works good on fans too

agree, better to use blow dryer

And how, exactly, does a vacuum or a blow dryer quiet down a noisy fan? But, if you all insist on discharging static electricity in to your mobo, have at-it.

first you remove the dust bunnies that are impeding air flow around your fan, then if it's running ok but still noisy, a nice program i found:
