M4300-48X Running Temperature high
I have a switch stack with the M4300-52G on top aand the 2 M4300-48X underneath. The M4300-52G operating temperature is 54C (stated max. in GUI is 90C). I can fell the air exhausting from the fans on...
I am also amazed after going through the 1147 page CLI manual for the M4300-48X that this switch does not have user selectable cooling profiles the sames as my ReadyNASs do.
I don't think that's normal - open a support ticket via https://my.netgear.com/

Network switches are - different from some (typically desktop) NAS - not operated in noise sensitive areas, and are configured to the best cooling possible. For some (smaller) M4300 models the fan algorithm was changed with a recent update towards non-rotating fans at lower to average temperatures, don't think this should apply to your versions.
I have opened a ticket, but no real help yet. I've done more testing in to the problem and the fans on the netgear labeled PSUs don't turn on when the swirch is powered up. But I happen to have a non-Netgear labeled compatible PSU that I installed to test how it reacts and the non-Netgear labeled PSU fan does operate when powered up. So I'm still dazed and confused that my new high end and expensive switches are having such basic issues with no quick solution as of yet. I also own Netgear's high end rack NASs and at least they have user selectable cooling profiles built in the firmware. I'm very disappointed so far, but hoping for better from Netgear...

The PSU fan on the M4300 I have at hand here does spin-up when power is applied - something is wring there.

Forget this part, in the switch world there is no such control - and on ReadyNAS it's a feature that came from the small desktop systems as part of the software and feature standardisation. In a dense rack config, and with average to high NAS usage, you won't have much of a choice - as the adjacent boxes will bring a lot of heat, too.
LaurentMa do you have an idea what is going wrong there with the OPs M4300?
Just to show you I'm not talking crazy, the attached photo is a ReadyNAS 4312X, a rack mounted Datacenter grade NAS. Not a Desktop Unit... I included the drives in the photo so you know this isn't a desktop unit.
