Hi Jussi,

The tube temperature is the main concern, not the exhaust air 
temperature (unless you worry about damaging the cabinet or something 
next to the cabinet).

No, but the tube seals are especially critical. You need to measure 
the seal temperature. The air temperature coming out of the cabinet 
tells you nothing about the tube safety.

You should measure the seal temp with a temperature sensitive crayon 
or paint.
