For motorsport we use the probe style pyrometer as we want to know the tyre carcus temperature, infrared guns show the surface/skin temperature.  Cheers Gary |

And I've decided to put that 8"-tall amp onto a 15" shelf, so it will be no warmer than if it were in free air. If I wanted to put it on my "standard double-wide" stand, I'd need to use some washers to create some clearance above it (the DW stand supports are 8" tall).
I may ultimately do that, but with a 9 & 7/16 inch tall McIntosh MC205 coming in, I'll need the 15" tall supports anyway.

Keep your equipment as cool as possible. Most chips are rated to 85C for local ambient temperature. Most electrolytic capacitors (think power supplies) also use 85C caps. Caps are the major item that are effected by heat and one of the most critical components of a power amplifier. For every 10 degrees C rise in temperature the life of the cap will decrease by a factor of 2. Chips are more effected by thermal cycle (mismatch of various materials co-efficient of thermal expansion). If you are operating anywhere near the thermal shutdown temperature your equipment's life is severely shortened. If you equipment is in an enclosed cabinet, it will get much hotter than on an open shelf and a cabinet cooling fan is most wise.

I got a free bonus fan from the HVAC system. Up from the floor and deflected by the bottom glass plate of my HT rack system, so no temp. Extremes.
Besides that the Sunfire amplifiers are some of the coolest cucumbers 🥒 on the face of the planet 🌍!
