best type of processor fan??

[surfactant]

I am using a big 92mm fan on my AMD XP and thermalright copper heatsink. Which type of fan is better, longer lasting and better performing, a dual ball bearing or "sleeve" type of fan??? any help appreciated. Mark

IIRC, sleeve is typically quieter and dual bearing typically longer lasting and more reliable (and more normally used for higher RPM [faster blade rotation] fans).

in practise though, you might be better off asking specifically for what you want, e.g. "XP2200+ oc to 2000mhz, need a super high performance fan, not bothered about noise" (or whatever), since brands and models vary significantly.

usual reccomendations i think are the low rpm panaflo's for a quiet to mid-speed reliable fan. delta or vantec Tornado if you're deaf (and have deaf family, pets, possibly neighbours) etc., though if you ask no doubt you'll find out


edit: presuming thats a SLK900 (or up), you probably could use a pretty quiet panaflo and still have room for overclocking, so long as your case ventilation is decent.

Not in my experience. I don't think the bearing type affects the noise, as much as blade design, fan size, and rpms do. Dying bearings though, will definitely affect the noise, and as you mentioned, sleeve bearing fans tend not to last as long.
I only use ball bearing fans now, or Panaflo's "hydrowave" bearing.

point of second paragraph was to indicate you cant just assume a sleeve fan is quiet etc., and going for specific brand + model is a better way about it. wasnt too clear though, is now
