Installing fans is really one of the easier parts of building a computer. You simply must remember which direction you want the air to be blowing and where you want the wires to go. It is made easier still with items like the tool less Anti-Vibration mounts that Noctua has included.
*When installing fans the air is always going to come out of the side with the frame that the motor is mounted to.
Since we have such a variety, I installed all three of the 120mm’s as well as the 2 140mm fans. First step, simply align the fan holes with the mounting holes in your case.
Now while holding the fan in place with one hand place one of the rubber mounts through the holes into the fan.
The mount simply needs to be pulled hard all the way through until the cone shaped nub is on the inside part or the fan mounting area.
In about five minutes I had both 140mm fans installed in the top of our test case.
Next I put two of the 120mm fans in the front of the test case. This case employs tool less fan mounts. I simply had to remove the rubber anti-vibration pieces from the ends so they would fit and slide them into place.
Lastly I replaced the rear fan with our final Noctua 120mm PWM fan. Since this fan is PWM I decided to attach it to the CPU_FAN header on the motherboard and control it that way. While I could have used the easy rubber mounts here, I decided for testing purposes to use fan screws. They turned in easily and didn’t cause too much damage to the hole. This is good as some fans use a more brittle plastic and the screw hole becomes less and less useable over time. That shouldn’t be the case with these Noctua fans.
