Maxamps water cooled lipo packs

But it doesn't apply to motors, does it? What about car motors? Do I increase the efficiency by cooling it with a fan or the magnets still dissipate the same amount or power as heat?

So what's about the perfect temperature for lipos?

Motors dissipate the same amount of heat regardless of any type of cooling. Actively cooling a motor can help shed that heat to prevent it from building up to the point where magnet damage can occur. However, if a quality motor is used, efficiency is higher, and there is less wasted heat to begin with.

Using a fan to remove motor heat is not a good idea if that is the only way to run it without having it overheat. The motor should be able to run without added active cooling with no problems. If not, the the motor is too small or simply wrong for the application.

IIRC, right around 90-95*F.
