Cool On Demand
The FDB 135mm fan will switch to hibernation mode automatically once the system’s load is lower than 20%. This will maintain the power supply’s stability and noise levels. The fan will begin to rotate when the system’s load is over 20%.
System Load < 20%
Zero RPM Fan Mode
When the system is under 20% load, the fan will automatically stop running to effectively reduce the system’s noise and lengthen the longevity of the fan.
System Load > 20%
When the system is above 20% load, the fan will automatically turn on to maintain optimal cooling.
Note: Zero Fan “On” position
