120mm Fan Testing on an MCR120 Radiator Round 6

[jalyst]

Looks like the high speed versions will be sold in US markets very soon......but only non-PWM by the looks of it

Yeah it sux hard....
It's looking more like I'll have to get it from you, if you're still offering?

You can see in a video I made for bing....the PWM version runs at about 2400rpm at the lowest duty cycle with Gigabytes CPU header....but with a proper PWM controller, at 0% duty cycle, the PWM version will run at about 1000PRM.....so, if you want the best, petition Scythe for the PWM version

What does "lowest duty cycle" mean?
What is a "proper" PWM controller?

Aren't recent top-end motherboards sophisticated multi-fan (pwm) controllers themselves?
Or are there still much better stand-alone controllers out there?

I'd prefer not to have "yet another device" in my build.
Especially one that takes up one 3.5" or 5.25" bay...

But if it offers much better reliability/flexibility than a mobo...
Then I'd be prepared to fork-out for a top-notch one.

Sorry for the million and one n00b questions
