Can anyone suggest a PWM compatible Fan controller that supports ideally 10 but at least 5 fans (all Corsair SP120s Performance edition)?

Also Im trying to understand wattage but im getting a bit confused, Does anyone know how much wattage is required by each fan running at full strength?

Thanks for your help in advance! :)

In theory, yes 10 fans would be able to be controlled by a single 30W channel controller BUT, the listed amperage I'm suspecting is the running amperage and not the starting amperage (fans tend to draw more amperage while starting than once running). I have no clue what the starting draw might be but it could be as high as 2.5A (30W - which would be the max per controller channel)

Thanks for that info on the wattage!! That seems really low considering alot of controllers are now doing up to between 30 and 60 watts per channel. Does this mean I would theoretically be able to run 10 fans on 1 30 watt channel at full speed? That doesnt seem right can you confirm this for me?
In regards to the controllers, I understand that all controllers will work, but I am looking specifically for a 4 pin PWM controller not a regular 3 pin, any suggestions?

Thanks for the response!

The only ones I am aware of along those lines (that aren't simply a motherboard pass-through with direct power option - which can work fine BTW) are DIY projects with the nicer one's incorporating a thermal probe for automatic adjustment
