Hi,

I have ordered one SFF21E and one SFF21D. While the D is near silent, the E is quite loud!
I would not even consider it a low noise fan. Is it defective, or is the E really that much louder?
(Is Scythe ok at replacing defective fans?)

Thx!

Unrelated: Oiling my old Nexus and old scythe fans had no impact :(

When running at full speed, any 120 mm 1200 rpm fan (like the E version of S-FLEX) will make noise by creating turbulence. The S-FLEX should become inaudible somewhere between 500 and 700 rpm, depending on your hearing. This model is useful, if you want the system to be inaudible when not doing much, but the components are too hot for low fan speeds when stressed.
