In tackling your cases cooling needs, there is no one fan fits all. Each of the two 140mm fans in the MasterFan Pro series provides a specific air cooling solution while all being fitted with multiple layers of our exclusive noise reduction technology and adjustable speed profiles. Put together, they work in harmony to cool your entire case and its components. Air Pressure fans are ideal for funneling concentrated air short distances at hot components or tight spaces. Recommended for use on the front panel to penetrate mesh wiring and tightly packed HDDs.


  • Fan blade design inspired by helicopters. They move the air less distance but pack more force into the space in front of the fan.

Speed Profiles

  • Switch between three curve profiles for your preferred mix of silence and speed.

Quiet Spin

  • Exclusive technology stabilizes the driver that spins the blades, reducing clicks and noisy vibrations.

Noise Absorption

  • Rubber mounting inserts on the frame absorb fan rattle

Jam Protection

  • Automatically stops the fan motor if jammed by objects.
