Temperature / fans X440-G2

Temperature / fans X440-G2

Hello,
I'm trying to deploy an X440-G2 switch but I meet a problem with the equipment

When I plug in an AP 7522 for example, after 5min I have the fans racing and making a monster noise, with a temperature rising up (I only have two ports plugged in on the switch) another POE equipment causes the same thing... This is the first time I have deployed an X440 switch, has anyone ever meet this problem?
Switch faulty?
I am in version 22.7.1.2, I was able to find on the Hub similar topics but that indicated that they were fixed with a version 22.7.1.2.

Thank for your help

Sounds like this issue.....
https://gtacknowledge.extremenetworks.com/articles/Solution/Fan-Speed

  • When providing PoE to fewer than 6 devices, the fan speed on X440-G2 PoE models rises to over 15,000 RPM.
  • Upon exceeding 6 connected PoE devices, the fan speed begins to fall back to normal levels.


Thx to @Anton Sax for working together with the GTAC on this issue....

Are you boiling the switch in hot water? It says 92.94 degrees Celsius!!! Ok, that may be a faulty sensor or the I2C bus not working as expected, so please verify for us that this switch isn't burning hot!
