Hi I'm building a lab bench power supply and was wondering about the thermal design i have ordered a heatsink which should be adequite for the task . The question is how to install it, would it be best to install it with the fins sticking out of the back of my PSU and keep the ambient temperature mostly equal to the room temperature. Or would it be best to install the heatsink with the fins in the case and having a higher ambient but create airflow with a fan and possibly another fan pumping the hot air out of the case. it is worth noting that i plan to install both a voltae regulator(T0-220) and a power transistor(TO-3) on the heatsink.
I have tried google and youtube but can't find much on the topic.
Thanks in advance to anyone willing to help or maybe point me to a resource for this kind of knowledge.
