The sensor is located on the case (not near the exhaust) of the server. With the structure of my appartment this is the only place I can realistically put my Server but sadly also the hottest place in my appartment.
The outside temperature is supposed to reach 36°C today so I expect the ambient temp for the server to rise another 2-3 degrees.
My server rack is located in an uninsulated attic with two tiny windows. I haven’t measured the ambient temperature but I think it’s over 40°C. Yesterday one drive in my storage server reached 65°C - so for today I have shut it off until the rain comes. Fun times.
Ouch, I will defenelty check on the system temps once I get home. Although I can’t really shut the whole thing off, maybe I can at least spin down the drive pool and kill all containers relying on that.
