What are cpu cooling bearings and what types are there?

[L10YD357]

I see that there is something called bearing type on cpu coolers. I am building a budget amd gaming pc, my build includes:

mobo - asus ma970 le r2.0
cpu - amd quad core either fx or phenom series
gpu - hd radeon h7770
ram - Crucial 4GB Ballistix Smart Tracer

1. What are they, what do they do?
2. What types are there?
3. Any differences between each type?

Thanks

Hmmmm.....Frankly does it matter? I think you should just look for coolers based on real world performance and noise levels.
