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 the M4300-52G. Both M4300-48Xs have an operating temperature of 73C (stated max. in GUI is 75C). The case fans are running so slow that I can't fell air exhausting from the case and the fans on the PSUs are running. Is this normal for these switches? I would expect the M4300-48Xs to operate at a similar temperature as the M4300-52G. Plus the fans on the M4300-48Xs are operating way slower air flow wise than the M4300-52G. I hope someone has some ideas? Firmware on all 3 is - 12.0.7.15, B1.0.0.11 .

Hi jpass022 Thank you for all your messages. I am sorry that you encountered an issue with a power supply unit with no fans apparently working. NETGEAR M4300 switches have a functional fail rate that is extremely low as we are striving for maximum quality, but a defect can happen during transport etc. You followed the right process by opening a ticket at NETGEAR Technical Support, as your problem will be assessed and you are entitled to a lifetime next-business-day replacement for any hardware defect like that. Your ideas about firmware are great, but for your information, fan speeds aren't controlled by a software image in a switch firmware, this is not a PC motherboard. Again, if your PSU is defect, we shall replace it. Please send me your ticket (case number) by private message so that I can see why you say that NETGEAR is slow to respond to you. This forum is a Community forum only, hence it is important to log a case at NETGEAR Technical Support when there is a technical issue. Regards,

Hi John thank you, I have escalated your case, a Technical Support agent will contact you. Laurent Masia

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'm very disappointed so far, but hoping for better from Netgear...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?

Hey I'm perfectly aware - as I said, thuis is a desktop consumer feature carried forward while scale-up REadyNAS OS 6 to bigger rack mounted platform. That's why it's in place. Not because e.g. the Netgear switches are coming with such a feature.

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 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...
