140mm fan #1 - Xigmatek XAF-F1452:

This is the first ever 140mm fan to be tested on the brand new rig. The fan is 140mm in diameter but comes wtih 120mm mounting holes. Fear not though, as they include four little extending arms that you can use if your chassis only has spacing for a 140mm fan. It also comes with an uncommon Aeronautical Oil System bearing which I know not much about, but apprently it has a much longer life span than the bearings of the included heatsink fan (150k hours compared to 40K hours).
The RPM is very consistent in every single operating mode so naturaly the acoustics are just as good and are not likely to change rapidly.
Besides that, I can't really tell you how well or bad the fan is performing since it's the first one to be tested, so we'll see how it'll stack up with the competition.
PS: Don't compare the results of any 140mm fans to any 120mm fans. They're tested using different hardware and equipment so a direct comparison is totaly pointless.
PPS: I'll make a chart as soon as I've tested five 140mm fans, so be patient.
