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 Pi spends all of its time around 55°C in a 20-25°C room. Main server idles at 47°C. Those aren’t worrying temps.
Yeah I know my desktop is idling around 60. Yet I’d rather have it a bit less warm on the passively cooled device ;)
