There's an aquarium heater that has a dial on top, not a red knob. The
one with the red knob seems to be (very intelligently) limited in
temperature range.

The one with the little bar knob can be turned up to a "fish stew"
temperature by simply continuing to turn the knob.

Not a design I want for my fish tank, but perfect for my PC boards.

BTW: allow the heater to cool before  you rinse it off.
