Review on Derale 16759 Adjustable Fan Controller by George Miller

Revainrating 4 out of 5

Works as advertised.

It works as advertised but if you are running a large fan with it I will need to add a larger relay controlled by this fan controller. Also, I've had issues with flat tips on high current relays corroding, creating resistance that generates heat that eventually melts the relay socket. So I connect the wires directly to the relay terminals after coating them with a large amount of silicone dielectric grease. Then I cover the tips and bottom of the relay with Dip It plastic coating. It seems to have solved the problem.

Pros
  • Fan and parts
Cons
  • Not as thick as other options
