Flexdrive... what side/components to heatsink?

I'm planning on running a flexdrive @ 1.25A or more.

What components on the chip need heatsinking?
I know the IC on the backside will need heatsinked and maybe the resistors.
What about the inductor on the topside or the little black thing between the capacitors on the topside? Anywhere else?

I want long duty cycles. I was going to use copper blocks and Arctic Alumina because it's not conductive/capacative and I plan on getting it everywhere. :D The 445nm diode will have an aixiz copper head mounted inside a larger copper heatsink too - so the diode should be cooled well.

hey,

what i do is coat the opposite side to the inductor and pot with thermal adhesive so it forms a insulation barrier to the driver heatsink, then while its still wet attach your driver heatsink to that side and let it sit for a while to set.

Copper driver heatsinks work really well too!
