Since the HP update, a dogfight between two small ships (in my case a <500 mass fighter against an isanth cc) is tediously long and painfull
I don't know about big ships combat (I have so much less big ships) it looks like it overheats when the ship took a big amount of block damage, but this amount is scaled down so it overheats only when the ship is damaged enough and it sounds good
But for small ships you have to target every block system until nearly nothing remains. For an isanth it took me several minutes with this weapon setup: 2x beam/-/exp damage pert tick: 2'000 x2
(this weapon setup is actually scary for a fighter, I can barely power it and it takes most of the place inside the hull)
While in this time the isanth had time to take my shields down even with the laughtable small weapon setup it has, and in the end I was badly damaged even if I had my systems waaay more beefed up than this poor isanth.
So I think the basic % of blocks that needs to be destroyed in order to overheat the smallest of ships must be scaled down a lot
