The Logisys Pyramid Thermal Fan Controller (Blue) has been DISCONTINUED....Please see our other fan controllers for an updated selection.
The blue Logisys Pyramid Thermal Fan Controller is a very useful accessory for any system. The Pyramid has all of the features of a baybus/rheobus without any of the work. The system works by using a thermal sensor that can be placed anywhere in your system. You can hook the Pyramid up to anywhere from 3 - 6 fans not exceeding 24 watts. These fans must be all linked together and hooked up to the Pyramid. The Pyramid will control the RPM of the fans according to the temperature sensored by the thermal probe.
