Coolerguys Thermal Fan Controller
Temperature controlled on/off switch

Great to control power to fans in your home heater or even your computer case!

Thermal sensor will turn the connected fans on at ~87°F (30°C) and leave them running until the temperature drops below ~80°F (27°C)
External probe (450mm / 18 inch in length) so that you can monitor the temperature away from the controller
Female 4 pin Molex on one side and (2) 3 pin male on the other.

If you are using this outside of a computer it requires an AC-DC adapter that has both 5V and 12V DC lines, this 2A adapter (Item #
840556029977) is currently the only one we carry that meets this requirement

Supply Voltage: 12v & 5v DC, separate lines
- Turn on temperature ~87°F (30°C)
- Turn off ~80°F (27°C)
- Can natively control 2 fans, you can add more fans using 3pin Y splitters but you must keep the combined power draw under 1000ma (1.0A)
- Green LED power light (always on)
- Size: 82 x 35 x 17mm / 3.22 x 1.37 x 0.66in

These controllers output power to 3pin 12v devices, if you want to use a device that has a 4pin molex connector you will need to buy an adapter for each device which can be found here

Probe length: 450mm / 18in
