I had a 3000 rpm fixed speed 3 pin delta delta it was between 2800 and 3000 rpm . quieter then the stock and kept the gear cool enough to go to freq 350. I think it is 148 cfm at 3000 rpm
Any idea on the model number of that fan? Trying to go by CFM and dBA on spec sheets I'm scouring... and when I start spec hunting I tend to go overboard.
and well... I went a little crazy...
I ordered a ridiculous SAN ACE 120 fan model 9SX1212P1K001.. (available from Mouser, Newark, Element14, Farnell, Arrow and Sager)
Here is a video of an older model Aluminum Sanyo Denki 6000 RPM fan...
