The Zalman ZM-MFC3 multiple fan controller allows you to monitor and control up to 4 different fans. The feature that really sets the MFC3 apart from other conventional fan controllers is that it displays real-time power load and consumption. The display was designed to ensure maximum viewing angles, perfect for cases that aren't in your direct view to be seen quickly and clearly. Four temperature probes allow for monitoring of 4 separate components. All the functions are easily adjusted and controlled via the large jog dial wheel.
