Pissed off by getting a noisy fan in the ZM-F2 92mm fan (as compared to the 92mm in the CNPS7000A-Cu) I asked Zalman what the specs of the fan were:

--------
The 92mm fan ''ZM-F2'' is diffrent from the fan of CNPS7000 series.

ZM-F2 (PS92252H)
Weight : 85g +-10%
Bearing : Sleeve
Normal Mode : 2,800RPM (2,500RPM - Fan Mate 1 Max.) +-10%
Air Flow : 53CFM (44.5CFM - Fan Mate 1 Max.) +-10%
Noise Level : 36.1dB (32dB - Fan Mate 1 Max.) +-10%

Silent Mode : 1,600 RPM - RC56 connected (1,300 RPM - Fan Mate 1 connected)
Air Flow : 27CFM - RC56 connected (24CFM - Fan Mate 1 connected )
Noise Level : 20dB +-10%

The RC56 resistance connector makes ZM-F2 to run slowly as if its input voltage were about 6V.

Well, that's that, for whoever is interested. And NO I DON'T have access to any panaflos.

Those things are loud and push a TON of air at 12V. At 7V it cools at least as well as my 92mm Nexus at 12V, but is actually a bit noisier.

Even though it has pretty quiet mechanics, it's really more of a high speed fan, so you'll always at least have higher turbulance and wind noise. Noise to CFM is probably one of the best out there and the low price makes it ideal for overclockers wanting to quiet the hairdrier down a bit, but it's just too fast for silent or very quiet computing.

I use that fan all the time for rigs I build because I like the reasonable noise level and very high CFM and very low price. Excellent fan, but,0 I agree, has no place in discussions for a near silent rig.

I'm using one in my pc right now. Yes, it does push a lot of air, yes it is far too loud. It's a temporary measure, dont really want it there next week...

Whoa, I'm glad I saw this post! I was about to buy a couple of ZM-F2s thinking they were the same type fans as the one on my CNPS6000-AlCu (Which I run in 'silent' mode).

Thanks! I'll probably go for a Nexus 92mm now.

Ehm.. what in a fan can make a +-8,5g weight difference?
