80 mm exhaust fan and 120 mm intake fan enhance the air flow inside NUUO PSU
 
NUUO with 2 Fans   Regular single fan PSU  
   
Additional intake fan increase the airflow inside the case The additional intake fan works accordingly to the 120 mm fan on NUUO
 
 
 
 
   
     
   
 
Temperature Monitor Fan controller controls the 80 mm fan and senses the temperature inside NUUO.
 
 
 
*When NUUO is not connected to the controller, the fans will be temperature regulated and operate automatically to cool down the PSU.  
 
 
By switching the knob on the Control Panel, NUUO Series PSU provides 3 modes to set the fan on NUUO PSU working efficiently and quietly.
 
 
  AUTO Mode¡G

You can switch the knob to "Auto", and the 80mm fan controlled by Control Panel will adjust its speed according to the temperature inside NUUO.
 
 
Smart Protection Mode¡G

You can switch the knob to "Low", and the 80mm fan controlled by Control Panel will operate at lowest speed until the temperature inside NUUO exceeds the threshold when NUUO Smart Protection System automatically raises the fan speed to protect NUUO. By this way NUUO PSU works quietly if power consumption is under 60% load.
 
   
 
Manual Mode¡G

You can adjust fan speed manually by the knob. Adjusting the fan speed manually provides users the flexibility to "manage" PSU airflow as well as noise. For example, you may make the fan work at the highest speed to ensure the maximum airflow when overclocking. Or you may make the fan work at low speed to ensure the silent environment when watching movie or sleeping.
