The Prolimatech Megahalems have very densely packed fins like the TRUE. This means that you need a fan with a high static pressure rating. Look for the 120mm x 38mm, rather than the 120mm x 25mm fans. The Scythe Ultra Kaze is an example.
What is a "high static pressure" ? You mean the CFM? Why won’t a 120-25mm fan do a good job?
ULTRA KAZE looks good, but I don’t want it to be the loudest part in my PC, will I be able to tune it down using BIOS or something?
I was looking at the S-Flex SFF21G 75 CFM/35 DBA 1900RPM But its 120-25mm
