Sorry, aig, but Zalman F3's use sleeve bearings, not Sony FB bearings, and seem wear out rather quickly.....at least in the five I've used. Three had bearing failures within 6 months, the last two are about a year old and are making horrible noises when spinning up.
The S-Flex fans I've got in use, five to be exact, have been in use for well over a year with only a whisper from them. (Three S-Flex "E" and two S-Flex "F" fans.....the F's are on a rad and two of the E's are rad mounted, the other E is a case intake fan.)
Spend the money up front, the longevity and superior undervolting ability of the S-Flex fans move them way above the Zalmans or Yate-Loons, IMHO.
