I got these to press in the space between fins on aluminum heat sink on the back of an MPPT solar charge controller. I am running it at its max so to help keep it cooler these thermostats, in parallel for backup, click on to run a cooling fan. They click on at close to 45C which is about 350 watts on the controller. The controller is rated at 550 watts so it is doing very well.

I had bought 2 of the 12volt power units (from China) and the units work very well with one exception the fan noise on these are horrible. Saw a YouTube post of how to fix the fan noise. With the switch you can run in inline with the fan, and then place the thermal sensor on the transistor heat sink, this will keep the fan off until a desired temperature is reached and then the fan will turn on. These are set at 45 C for on and 33 C for off. Under load the my 12volt power supply never reaches 45 C it never peaks above 33 C so why is the fan constantly on? Well here you go away to eliminate the fan noise but not loose cooling when required
