How Often Should I Replace My Computer Case Fans

post #1 of 12
Thread Starter 
It's been a year now since I built my computer. I have a few fans in the front of the chassis. Is there a sign that indicates I should get new fans.

Weird noises or just plain dead..
Chassis fans are not something that would fall in basic maintenance, not until they break completely..

Some people like to open them up and lubricate them depending on the bearings they use, etc.. I think that's a waste of time..

Maybe if you want more quieter fans. Or lower temps but I'm guessing that has to do a lot with the airflow I'm your case. I'm no expert though

Till their dead? Case fans aren't like other components, you can pretty much ride them till their dead.

You'd know if a fan needs replacement...it will either not turn at all or turn really slow. Though make sure that it isn't a fan controller issue before you replace the fan. They should spin easily with your finger too when the power is off as well.

I've never heard one make noise that wasn't physically broken, but I'd consider any unusual noise bad.

All you can do is oil the bearing occasionally, honestly for your average run of the mill cheap fan it's not even worth it. if you have some expensive fans then it I might consider it.. The main thing to ensuring long life of your fans is to keep them clean. Dust build up on the blades causes an uneven revolution, putting more pressure on one point of the axle/bearing than the other causing uneven wear. drastically reducing the life span of your fan. There are guides on here that show how to oil bearings if you choose to do so. thumb.gif

I've had the same case fans for 7 years, if that tells you anything.

What kind of music does your fan play? I'm sure it has learned a tune or two considering its age.

When they stop functioning normally.

Don't know why else, other than deciding to upgrade.

When they die. They usually last quite a few years. Some companies have even 6 year warranties.
If you want quieter operation or better airflow it's worth it to upgrade the fans thumb.gif
