    Bearings or sleeves for fans?

    I am not sure wether or not there is really a difference. I was just curious if one method was better then the other. I have heard that bearings last longer, not sure if this is hear say or not. Bah who needs fans when there is H20! Woot!

    Absolutely go for bearings, doube ball bearing vs a cheap plastic sleeve. More dependable, longer life and quieter.

    Actually from what I have hear the sleeve bearings are a tiny bit quieter, but they do not last anywhere new as long. Most bearing fans have one sleave and one bearing. Dual bearing fans are a bit more expensive and are primarily used for servers as they are designed to run for 70-100 thousand hours average. Sleave plus bearing last about 40-60 thousand and sleave last about 20-30 thousand.

    Bearings: Louder but better dealing wth heat.

    Sleeve: Generally quieter but durability/longevity is affected if near a heat source...
