Top mount, tail mount, bottom mount… Heat sinks are becoming more and more popular as we push those amps. We’re all for aesthetics here so let’s see some photos of those cleanly mounted, heat sink’d escs!

Who else is making them?
Love how nicely that lined up
(time to pop that cherry. First post 
) thanks for getting this rolling @Venom121212
What’s the general rule of thumb for when to add a heat sink?
I’ve been riding without one for a while but it hasn’t been too hot out and I haven’t pushed any boundaries yet. 12s5p p42a mtb.
Welcome!
VESC tool’s mosfer cutoff start temp is 85°C and hard cutoff with a fault thrown is at 100°C by default.
Personally, I don’t like a hard fault being thrown so I raise that one up to a temp I’ll never hit. Cutoff start temp I abuse and let the esc get too hot so I won’t share my number just yet 
If you start thermal throttling you know it’s time for a heatsink
If you have telemetry it’s easy to see, but for me, it was blatant throttling on my GoFoc retro lol
The power cuts way down
3d printed top plate made for dual ESCape heatsink
yes i broke my METR antenna 
Recently did a repair on a heatsinked enclosure I bought second hand:
Still need to hit it with some paint!
Man I remember seeing this one and loving it. Falling in love all over again 
Thanks! I’m quite proud of it,
maybe someday i’ll buy a new unity and i’ll trim down the extra antispark’s cm,
that would look a lot slimer on the board
Can you share the STL for that?
Yeah, I’ll try and remember to stick it on thingiverse this evening.
Thanks! Your fix is
