Speeds range from 1200 RPM idle start speed to 2400 RPM at full speed. SXT80 fans have a thermal sensor that detects the temperature and tells the fan how fast to run. The sensor should be located on or near the heat source for optimal performance. When the sensor detects heat above 77°F the fan speed will begin to increase.The fan will reach full speed of 2400 RPM at 104°F. Fan Controller User sets the controller's on and off temps to start and stop the system. Typical start temp is about 80-85F. Off temp at or slightly above room temp. These settings can be adjusted for optimal performance. The controller has a temp sensor that should be located on or near the heat source, or can be located at the top of the cabinet for an ambient reading. This temp is displayed on the controller during operation for easy monitoring. Or, the display can be shut off during operation. (See Operating instructions) Each of the 4 fan power connectors are numbered 1 thru 4 corresponding to the front panel LED indicators. When the LED's are on that fan will be on. When the LED's are off those fans will be off. Global setting: Front panel LED's for fans 1-4 are all on. Individual setting: Front panel LED on for one fan at a time. Temperature Sensor Place the temperature probe where you want it to detect the temperature. It can be left as is on the panel for an ambient temp. Or it can be placed at the top of a cabinet or above a hot component. Try to avoid placing the probe where the fans will blow directly on it. For best results, locate the probe where it will detect the most heat.
