Question Unbelievable fan

This fan is claimed to have 90CFM and 19Dba and is kind of cheap... I couldn't find the fan on the coolermasters website either. I'm going to guess this is a typo. being that no other fans come close to this CFM : DBA ratio...

Thats the R4. I use one, but it's 19db at the lowest RPM. More like 36 or 40 at full RPM. It's a nice fan though. I use it on my Megahalems cooler.

Correct. The dBA is MUCH higher than the rating, at full speed. The fan itself makes for a good case fan, though there's still better, especially on restrictive surfaces.

I had tested that fan against the Scythe S-Flex G (75cfm @ 1900rpm) and the S-Flex G air-pressure was greater than the CoolerMaster. I was trying to decide between the two to see which one I was going to use with my Megahalems. CoolerMaster was placed back in the closet
