Sunbeam fan controller hot to touch?

Is it just my fan controller that is hot?

Might need some details here: Which sunbeam controller is it exactly? Is it a Sunbeam rheobus or Theta controller?

If it's a rheobus I'm pretty sure that's normal as it uses rheostats to control fan speeds and they release excess heat into the surrounding air. Make sure you're not overloading any of your controller's channels, and mount a fan behind it if possible.

If it's a Theta software-controller, I haven't the faintest idea why it would be heating up. Pretty sure those are PWM controllers somewhat like the hardware controller that I use..

Like grumperfish said rheostats dump the extra current as heat. So the lower speed you set the fan, the more heat your rheobus will create.

If a PWM unit not sure what to say.

Just checked mine (the one that comes with hte PSU)

Cool as a cucumber, thats in the fridge.
