[QUOTE="Tob, post: 16314767, member: 83412"] I tried the Derale unit, ignoring all the advice against it across the web and bought one anyway as the features sounded too good to pass up. Sure enough, I had the same issue others ran into - the tape on temperature sensor (and I had the latest one made available). The fans simply wouldn't come on at 200+. Tested everything, all good. Sensor was in range. Bought another sensor, same issue. Derale tech suggested what I had already tried - moving it up on the cold side until it would work. I was damn near the top of the radiator and it was still activating way too late. I bailed. The Derale sensor is attached at the cold side using 3M two sided tape. Under the tape is a small circuit board. I could heat the sensor up with a heat gun and the fans would activate just fine. I also wasn't big on wiring the control unit direct to battery hot and ground. The Autocoolguy runs hot leads from the battery to the fans and then the grounds from each fan run to the control unit. In addition, it uses a traditional coolant sensor that is located in the coolant stream (on the cool side). The controller connectors are bigger as well which is something I felt the Derale left a bit to be desired. [/QUOTE]
