Better to use an angled aluminium stand with a Mac notebook. The typical powered cooling pad's designed for Windows notebooks don't really do much due to the design of Mac's.
The angle of the stand will slightly increase the Mac's convection and the aluminium will wick away heat from the base plate. If you do opt for a powered cooling pad, look for one with a large single fan and can push 100CFM or better.
You can also augment an aluminium stand with a USB fan placed at the side of the MBP and or use an application such as
Mac Fan Control to manually increase fan RPM. Bottom line is the Intel based Mac's run hot by design, the Apple Silicon Mac's I wouldn't worry as they remain physically cool unless under full load for extensive periods of time.
