Fan Controller gives off heat

[TaranScorp]

I've been researching which fan controller I should purchase and am thinking about the Sunbeam RHK-BA 5.25" Black Rheobus or a Sunbeam RHK-EX-BA 5.25" Bay Black Rheobus Extreme for my seven San Ace fans but I read some reviews on the Rheobus Extreme that it gives off a lot of heat which seems to me a little ironic. I'm getting a fan conlroller to keep the heat under controll in my computer cause of the heat my fan controller gives off?

when you downvolt,

your reducing power, but this causes strain on the power regs.

Its when you down clock, and downlock on a lot of fans where u see controllers get hot.

Is there a fan controller that doesn't get as hot. I have seven fans and I am not going to run any of them at full speed at 2600rpm. Or will the Rheobus just have to do?

I just buy fans that run around the speed I want. But I would assume anything that uses electricity gives off some heat.
