If you're going for pressure the Ultra Kazes are great, if you want reasonable acoustics, the S-Flex series, Kama Flex series or Yate Loon 12SLs (~1200-1350 RM on a controller) are superior. The maximum RPM you want for a quiet setup is around 800-1000 RPM.

Panaflo are incredibly hit-and miss in retail, so be careful.

I usually buy my fans at Performance-PCs because they come pre-sleeved.
