Quark 125b help please

[pullinteef]

Does anyone have really good knowledge of how 125b settings affect the heat of the ESC and motor? I've using one for 2 years now, really smooth and works great, but with my 1512/2D/S I can't gear above 12/46 (calculates to ~32mph) on an RC8 without things getting pretty hot (at 14/46 I thermalled after 7 minutes and motor was at 190ish) But I see other people geared for 40 mph saying things run fine. I've been running with no fans forever to simplify things and it does run great, just not crazy fast in the long 180' back straight at our track. BTW we run 15min mains and it makes it fine at 12/46 but I've had the motor up to 190-200 a couple of times now and don't like doing that. (I have one of the Neu's thats hard to turn the shaft by hand, not the newer ones that rotate easily)

So back to my original question, which settings affect ESC and motor heat? Such as:

Battery Selection:
Lipo high = hotter ESC and motor
Lipo Normal = cooler ESC and motor (I assume, but are these right?)

Does custom cutoff voltage make a difference like on the MM (I use one in 1/10 4WD)

Drag Brake higher = Hotter ESC (I think), Motor (?)

Torque Selection = This I really am unsure of, does "smooth initial torque" draw some of the energy out of the system and actually make the ESC hotter?
