Push & pull yates Vs 1 tribewerk. (push pull yates = cheaper solution still).

I can already predict the answer.

*hint* im getting rid of my san aces in favor of push pull yates.
Nothing wrong with yates or push/pull for that matter on any fan, just keep in mind the extra sound sources will increase noise level:

For example one fan that produces 45db on a radiator.
3 fans = 49.8dB
6 fans = 52.8dB
etc..

Here is a handy little calculator for playing around with that:

If you look at the noise vs. CFM charts, I'm not sure push/pull is nessarily better than a single stronger fan though. If we're having to step up 3 dB for push/pull, alot of fans could get a good 45% more air flow at higher volts for 3 dB more sound. So, you may get more performance from a single stronger fan than two weaker ones in push/pull...it may have a different sound quality though..
