When we check the temperature on that switch, it shows the MAC sensor at 33', and the PHY at 29' both are reporting as good.
We trend the temperature in SolarWinds via a Universal Device Poller that queries OID
1.3.6.1.4.1.674.10895.5000.2.6132.1.1.43.1.8.1.5

That confirms this. Is there any way, we can turn this reporting off? We can use Solarwinds to warn us if there is a large temperature change. Otherwise we get an email every time the fans speed up or slow down.
The switches are in a server room that is regulated at 20c. There is 2U under and above each of the switchs.
