As of the topic other than fitting the biggest heat sink and all its upgrades and not using power boosting upgrades? , I’m just toying around with this duelist super heavy corvette which makes the Elite mods a bit easy but I have a major problem with heat (so I don’t use the duelist much I still like the nippy patcom) , ie when fitting :
6+ assault cannons
or
6 AM PBC
or
10 Rapid fire PBC
or
10 assault cannons
I find my ship melts and I can only fire in half second bursts , though to actually be able to finish cargo ship escorts in a reasonable time I need all that fire power (took me 45 minutes to finish off a pair of heavies in the tug once in a circle of death when I’d run out of disrupters)
