In our home, we utilize a couple of
Legion 18 network racks. These particular 18U network racks are designed to be compact, making them suitable for placement in closets or offices. Additionally, they come equipped with built-in cooling features, specifically two 120mm fans located at the top of the rack.
However, while the built-in cooling is a valuable feature, I couldn't help but notice that the noise generated by the fans can be quite noticeable, particularly in quieter environments. One of the main reasons for this is that the fan speed is fixed; there's only an on/off switch available. Consequently, you can either turn the fans off entirely or run them at their default, relatively loud speed. This limitation led me to seek out replacement fans for the rack.

After conducting some research, I decided to opt for the
AC Infinity Rack ROOF Fan Kit. This kit includes two 120mm fans that can be connected to a provided fan controller, which, in turn, connects to a power source. The fan controller offers precise control over the fan speed, allowing for quieter operation.
