🔴 Efficient Cooling Solution: Derale 16795 PWM Fan Controller in Vibrant Red Review

Works exactly as advertised. Easy enough to plug in, bit odd to me that it goes straight to the battery, no power switching at all, but so far it hasn't caused any battery issues. Has a nice constant fan overclock and the same when the fan slows down. It's EASY to adjust to your desired temperature range and seems to stay consistent. I'm a bit disappointed that the module isn't well sealed against moisture and possible water damage, but I've installed it in a location where it should be…

Was on my Jeep TJ for about 8 months powered by a Lincoln Mk VII fan which I put on the radiator. The first one I ordered was DOA and I had to return it, the second one I ordered lasted 8 months but then suddenly died while driving and my check lights went on and I was about 240 degrees Fahrenheit. Coolant Temperature I IMMEDIATELY shut off the engine and pulled to the curb. Luckily my buddy came and pulled me and I checked things until I proved the controller was dead. To return home I…

I installed this product using the supplied wiring diagram in combination with a powerful 2 stage Derale fan. In the original configuration, the fan turned on immediately after starting the car, and not at operating temperature as expected. Initially, the air conditioning lock worked as intended. Then one day, for no known reason, the fan stopped working. I was lucky enough to get a replacement from Revain as the 30 day refund period had expired but it was still under the manufacturer's…

First, I'm always optimistic. I see bad reviews about such devices and think that people installed it or RTFM wrong and therefore have bad experience. I installed a dual derale fan shroud on my ZJ and am happy with it. So I jumped at the chance to buy their high performance PWM fan controller for $180. I was very excited to give my generator a much needed break and get some fuel economy back. I received the device on Sunday. It was nice and heavy, looked good and came with everything needed to…

I'm split 50/50 on this product. The controller itself is great. The rest, including the probe, is garbage. In my experience this is an amazing example of a Derale product. The included temperature sensor doesn't seem to work well in aluminum heatsinks - if at all. Ignoring the fact that "pluggable" sensors are generally a bad idea. Poor quality connectors - consider a clearance sale at any discount auto parts store. The supplied primary wire is a very lightly stranded, VERY stiff wire. Poor…
