I have a couple of heatsinks that I pulled off a junkyard forklift battery charger.
They have large fins, but ALSO two holes running the long direction through the base of the heatsink.
These heatsinks could be used for aircooling, but would be a snap for converting to liquid-cooling as well!
If anyone is planning a High-AMP version of the controller, keep an eye for for heatsinks that could potentially be liquid-cooled as well.
