Clutch temperature...
Regardless of temperature whether it is cool or incinerating temp; the lowest temperature revealed will be when you can run the engine at it's rated rpms.
Rated rpms: The rpms the engine makes its maximum horsepower at. 800R = 8150 rpms
If you run the engine higher than rated rpms [example 8400] the system temperature will increase.
If you run the engine lower than rated rpms [example 8000] the system temperature will increase.
So regardless of temperature you measure, whether its hot or cold or warm or burning or freezing - The lowest temperature you'll measure is when having calibration allow the engine to run at "rated rpms" on a sustained wide open throttle pull.
You will find and efficient clutch setup will reveal temperatures;
Hottest temperature is on primary stationary sheave [engine sheave]
Next coolest is the primary sliding sheave
Next coolest are the secondary sheaves.
Some will even find that primary sliding and secondary are cool vs. the engine stationary sheave.
The combustion heat is transmit through the crankshaft into the crank stub and onto the stationary sheave.
The sliding sheave is disconnected from the engine, the disconnection is at the inner sheave bushing....little if no heat will transmit through a bushing - the heat transfer goes through the belt.
Heat in the primary is caused by the belt moving along the sheave faces at a slower rate than full capacity and usually when the engine cannot run at its rated rpms.
If you are calibrating the system to run the engine at "rated rpms" - The belt will travel along the sheave face the quickest when the clutches are calibrated to run at rated rpms. Lower or higher than rated, the belt will not travel at the optimum rate.
