Interesting. But would that apply to cpu chips then? Its metal on metal. How i see the heatsink is it pull the heat from the motor and is quickly cooled down by the surface area of thr finsJust get a 40x40x10 Rocket alloy fan like @dure16 stated and use a Fan mount only. Pretty much plug and play.
Toss that stocker Heat sink altogether. It is useless. Air blowing directly at the motor is best. Faster, more sustained cooling results . My temp gun doesn't lie.
A motor's alloy Can is already a Heat sink by design. A Heat sink is just Bling, and keeps the motor from cooling faster. What matters most is fast thermal transfer. Why add even more metal mass of a Heat sink to cool down?? They don't even fit precisely enough to motors. In theory it works. Just not in practice.
Want even more cooling, just run doubles of this fan with a double fan mount or 2 single fan mounts, one for each, Space, Clearance and Length of motor permitting.
>>>A heat sink alone without ANY fan could offer a slight benefit over having nothing at all.
Then it seems easy enough to simply mount a fan to a HS. I get it. Arrma does that as many other brands do.
It's just far from the best setup at all.
That is a good questionWhat is a good fan mount to place the fan on top of the motor?
That's a more nuanced discussion than we're getting into here unfortunately. Heat is spread through contact (conduction, or touching between two solid pieces) and convection (fluid like air or water moving across a surface). Convection is better over larger surface areas, which is why CPUs use a heatsink to effectively increase area, but they also have to use a thermal interface medium (thermal compound) between the CPU and heatsink in order provide the best conduction heat transfer. Metal to metal is not a good way to conduct heat, which is why the arrma heatsink is not the best option. You could make it better by using some sort of thermal pad, but that's another discussion for another day.Interesting. But would that apply to cpu chips then? Its metal on metal.

Something like this works fine.What is a good fan mount to place the fan on top of the motor?
