Make Your EdgeSwitch Quieter by Replacing the Standard Fans 

The fans in switches from Ubiquiti (both Edge and UniFi) are rather noisy. You can replace the fans in your switch with much quieter ones. I chose fans from Noctua, which are known for their quality and quietness.
I used two Noctua NF-A4x20 FLX fans, which you can purchase from Amazon via the affiliate link.
