This applies to the Platinum Compounder and Platinum TwinTrak Pro & other Class A units
This is not a problem - these are class A devices so will generate heat. The units are designed to work while running hot and so the heat is not a problem, even on long sessions.
With any class A equipment it is important not to cover any of the air vents and it is advisable to leave a least 1U of rack space to allow heat to dissipate. Especially if there is a whole rack of class A equipment.
