Just saw some Cougar brand Vortex Fluid Dynamic Bearing fans.

http://www.newegg.com/Product/Produc...=1&name=COUGAR

The 14cm version is pretty expensive(23 each!
)
But the Fluid Dynamic Bearing is really promising and seems like people are pretty happy with these fans, however I doubt that they are as quiet as Cougar claims....

Any input on these?

The numbers on their 120mm fan are impossible, so I wouldn't trust any of their numbers.

A TY-140 is the best 140mm fan. This looks to be similar at least in blade shape. Also, the TY-140 is much cheaper.

The TY-140 have 120mm mounting holes which I can't use on my case.

Plus the TY-140 have sleeve bearing if I'm not mistaken, which is not as good as FDB bearing, and that's why they are priced much cheaper.

The TY-140 has FDB.

I've tried their 120mm PWM version...

comparing with my prior enermax magma this fan wins.
comparing with my delta FFC when my delta spins at 1300 RPM (PWM controlled), again this fan wins.

would love this fan, only if I haven't tried those 38mm beast

I recently installed the 120mm 1200 rpm version and it's working very well in horizontal mounting blowing up. It's astronomically quieter than my previous CPU fan which was a 120mm Sunon KD1212PTB3-6A 2400rpm 69cfm 35.5db

It's to be expected going from 2400rpm to 1200rpm and the fact that the Sunon was ball-bearing and this is FDB. What's impressive is the fact that my temps are the same and considering this thing puts out much less air than the Sunon I'm impressed.

There must be something to the design:

For sure the db ratings are off. I'm ballparking at 1200 and 1500 rpm they are probably around 20-28db if not a bit higher.
