Show Me Your Heat-Sink'd Enclosures

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!

(time to pop that cherry. First post :sunglasses:) 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 :grimacing:

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

Small and simple but it does help a little. Planning on something larger in the future :ok_hand:

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
