Caspers Electronics Fan Switches

Caspers Electronics Cooling Fan Control Modules

Caspers Electronics electric fan control switches are easy to install and allow you to turn your car's electric coolant fans on manually, yet still retain stock fan operation. Stock cooling fans are set to activate at 215 degrees F, which is too hot for high performance use. The easiest way to optimize the performance of your car is to run it at a lower operating temperature. So, if you're sitting in traffic or at the track waiting in the staging lanes between rounds, you can activate your fans early to keep your engine operating efficiently and producing as much power as possible. Lowering your engine's operating temperature will not only increase performance, but it will also increase reliability and engine life by decreasing the stress caused by heat fatigue.
