Derale PWM Adjustable Fan Controller Kit Probe Style160-210 Degrees # DER-16795

Hello, i use the derale adjustable fan controller, on mostly every resto I've done that use thermo fans, the soft start of the derale fan controller, is perfect when using msd distributor electronic spark devices, over the years many msd device's have been damaged by power spikes from the thermo fan start up.. i personally wouldn't use anything else!!
