Best fan bearing type?

post #1 of 15
Thread Starter 
Looking at 120mm case fans here, and I'm just wondering what is the best bearing type (will last the longest) for "install and forget" installations. In other words, no lubrication or any other preventative maintenance will be done on the fan, except maybe the occasional dust removal.

2 ball? Sleeve? SSO? Something else?

Ball? I know that sleeve is the cheapest.

Well that's what I thought too, but then I see these $15 sleeve fans and it made me wonder...

Ball is long lasting thou any type will make noise after sometime. Especially ball bearing tends to click at some specific RPMs if you control their speed biggrin.gif I'm liking my AKASA Viper but I use it on CPU cooler biggrin.gif

Is ball the longest lasting out of all of them? I'm assuming 2 ball is better than 1?

There's also:

Hydraulic
Hydro Wave
Nanoflux Bearing
SSO
Twister
Rifle
1 Ball, 1 Sleeve
Ever Lubricate
Fluid Dynamic

Lulz, didn't realize that.

So 2-ball is the absolute best of the best bearing design?

I always thought FDB (fluid dynamic bearings) were superior fans. I am not saying they are though, just wanted to mention the option. They are definitely a premium priced fan.

I've always thought that these "enlobal bearing" fans from enermax have potential.

http://www.xoxide.com/enermax-marathon-enlobal-fan-120mm.html

The fan hovers in a magnetic field and does not actually make any contact with the stationary parts. They don't move a whole lot of air though. I've been meaning to buy one and try it out. Technically these should last almost forever considering that there is no bearing to wear out.

Strangely I have never heard much praise about them. Opinions always seem to be mixed when I read reviews. I just wish somebody would take the Gentle Typhoon's blades and put them on this bearing/motor.

Some of the above are variations (in some form or another) of a sleeve bearing. Some high quality FDB fans are just as good as BB fans.
