The abnormal noise of the device is caused by the low-load protection mechanism imported, which does not affect the device performance. You only need to add POE terminals to eliminate the noise.

May I know whether there is noise from switch 1 or switch 2? Is the POE terminal connected to a noisy switch?

Hello, All the devices the gateway and the switches contribute to the fan noise. The 2 NBS3200 switches are the loudest. I will order a the NBS5200 non-POE switch, will take several months to arrive in the USA.
I am reviewing the new fanless Ruijie switch RG-S2915-24GT4MS-L but the specs are the same as the Reyee NBS3200 or NBS5200 switches.
I am not able to RMA the switches being in the USA. I can replace the fans with noctua models to reduce the noise.
Thanking you in advance.

The maximum POE power consumption of the NBS3200 is 370W. If the POE power consumption is greater than 10W, the device does not emit abnormal sound.

Have you ever tried to connect a POE terminal to the downlink switch? As long as the power consumption is greater than 10W, the issue will not appear.

The 2nd switch does not have any POE devices plus POE has been disabled on every port. The fan noise is still present.

I mean you should connect to POE device to this noisy switch( 2nd switch) so that it consumes more than 10W to avoid this problem.

The 2nd switch with no POE devices has the same fan volume/noise as the 1st switch with the POE devices.
