Thx.
I don't know, try a piece of both at the same time and measure all around the motor, find out where is hottest, then try some tape on there.

On my old Nosram, the endbell is hottest despit being plastic, on my hacker I have black duct tape, on my new Vector X12 I point it straight through the cooling holes to try and measure inside (was still only getting 52degC)

As for people saying you need to run them near the temp limit, I'm afraid I belive that's crap.

You need to motor running where it's producing the most useable torque and rev's if that happens to be at a lower temp, then so be it.

Remember, heat increases resistance so the hotter the motor, the less efficient it is....BUT, is that reduced efficiency producing grunt or being wasted!
