I wouldn't have said it if I didn't know for a fact it was true.
I'm not saying there aren't better fans out there - there are. They just aren't the ones that people think they are.
For example, the guy that mentioned the FM121, that's the exact same blade and housing design we use as the default exhaust fan on the 600T. They may have upgraded the motor or bearings, I don't know. But I know the fan blades, and fan housing are identical.
The stock fan that comes with H60 is a great fan - you'd have a hard time finding a better fan under $10 at the same RPM (1700) that will outperform it. Sure, you could go spend $15-$20 and beat it, but for the price, it's just about the best at that RPM. You could also buy a cheaper, higher RPM fan and beat it, but you'd sacrifice noise levels.
The H80 and H100 fans are rated from 900 RPM to 2700 RPM. The "High Performance" mode puts the fans on a curve from 1600 RPM to 2700 RPM (+/- 10%) and the static pressure is monstrous - over 7mm/H2O at max RPM. For pushing through radiators, they kick ass.
In order to maintain civility, I won't mention fans that sucked in our testing - but I'll just say there were some real surprises. Some fans did a lot better than expected, too. The golf-ball dimpled fan from an unnamed manufacturer we tested had really good static pressure as well. Probably not because of the dimples, but nonetheless it made a good radiator fan.
