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! :)

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!

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)

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
