There are other features that are distinctive for a good radiator fan. A. If the fan rotor is equipped with large and more flat blades, then it is a pressure optimized fan. So a fan mounted in front of the radiator will be a “pusher” fan: blowing air over the radiator with a positive pressure. To learn more about our Cookie Policy and how to manage cookies. The Rear or Exhaust side (the side that the air comes out of) of our fans will always be the side that houses the fan motor.

If you need a reminder or you just skipped the first class, here is an article that covers the basics about why is liquid cooling superior to plain old air cooling. The offset is normal and expected; a 4-pin header will support both 3 and 4 pin fans. Visit our shop and find out more about our high-static pressure computer cooling fans, designed and built primarily for highest-performance computer liquid cooling systems. Since you only supply power, there is a controller in the fan that senses rotor position and commutates the motor accordingly. For the final front-mounted configuration, the radiator had a gap between the 200mm fans, with no radiator fans mounted. The radiator fan gets mounted to the radiator by using a screw that mounts through the entire fan (in one side, out the other). for your computer case and CPU cooling radiator.
