Okay, test results.

12V (2500RPM) numbers:
82CFM @ 43.9dBA

10V (~2250RPM) numbers:
73CFM @ 40.9dBA

Few notes...the fan never gets really quiet, even at 5V. Makes this rasping/grinding noise, might not be noticeable in a case though. The turbulence noise is especially bad above 8V...below that the motor noise takes over. And most of all...even the 2500RPM version doesn't hit 90CFM. Interpolating from this data, the 2000RPM version should move approximately 65-66CFM and at an unpleasant ~38dBA.

Of all the fans I've tested so far on this testbed...the best performance at ~19dBA was the Yate Loon D12SL-12 @ 5V moving just under 26CFM (@19.3dBA). My previous tests can be found in the stickies of both the Liquid Cooling and Air Cooling sections.

In other news, I'm shocked at how bad this fan is...
