Ambient temp increase with tube amp


This is my first tube amp: Cary SQI-100. Who out there in audio land can shed some light on how hot these get? Factors? Placement, etc?
My thermostat is set at 72 and I recorded a temp of 93-101 at the bottom of the shelf above the amp. The amp is set up on open shelves in an alcove.
Temp recorded after trying a pair of new LRS for a couple of hours. I doubt that I'll keep these even though they sound great. I compared these with my Heresy IVs.  Might not be the best amp for the LRS? Volume with the Heresy IV's ~8 o'clock and about 3 o'clock with the LRS for the same listening level.

If it's actually a Cary SLI-100 I assume it has 4 KT150s...like having 4 100 watt lightbulbs under a shelf...they're supposed to be hot. My power amp is a far smaller single ended thing with only 2 power tubes and I give it and my tube preamp (4 tubes) lots of room in an open rack...
