Fan Noise

There are quite a few people in the Ubiquiti forums asking about the fan noise level of the UniFi Switch family. Keep in mind these are an enterprise-class device, and as such are intended to be rack mounted in a server room or data closet, and not used in the average home. However, Ubiquiti have attempted to reduce the amount of fan noise the switch generates by using variable speed fans that change in response to thermal activity within the unit.

The switch draws air in from the right using two small intake fans, passes the air over the internal boards and components, and exhausts the air on the left using two small outlet fans. While this is an efficient cooling design, small fans at high speeds are inherently noisy.

For those interested, I have taken some sound level measurements of the switch when idle (nothing plugged in) in a quite room. The room temperature was a constant 20°C (68°F), and the fans in the switch were running at their minimum speed.

Ubiquiti Unifi Switch 48: Fan Noise

Location Distance Level
Front 1 metre 34dB
Back 1 metre 34dB
Right (intake) 1 metre 36dB
Left (outlet) 1 metre 35dB
Above 1 metre 37dB
Room Ambient 1 metre 20dB

These levels are on par with normal personal computer fan noise, however, keep in mind that these are minimum levels when the switch is idle.

These measurements are not highly scientific and were taken on a smartphone using a free but popular sound level application. All samples were taken over the period of 60 seconds at a distance of 1 metre (3.3 feet) from the source.
