I forgot to resise the pic...brb
The heatsink is a big TO220 transistor h.s...that I cut with a hacksaw, and lapped...but left the side edges rough for more surface area the pic is a b4 and after pic in pic. Has helped in stability..and I will do it on all my future boards...this mod was easy, because I have nothing in the way..the h.s could have been taller, and it wouldn't interfere with anything in the case..although I would not make one any bigger than this one here.
one caviat though, I used too much arctic silver thermal epoxy, and came close to having it run all over the connections of the chip..as the pic will plainly show. This one is easy but be warned that gluing a h.s to a chipset is permanent, and you should make several "dry" fittings first b4 adding the glue
