Well, the shock isn't much, considering the heat paths into the motor. But I have a problem with using so much freeze spray - it is mildly dangerous (as much as, say, WD-40) and isn't healthy to breathe. Instead, fans (such as those on Victors, or the larger ones in the KoP) can be mounted to blow air across the motors at all times, this will make a definite difference.
But, it is hard to argue with cold-in-a-can, I don't have anything that can compare.

This is not ideal; either the cables are damaged (if hot in spots only), undersized (if hot along their length), or have loose connections (if the connections are hot). This definitely affects the power the motors can see and use. Avoid bundling wires up too tightly; allow some space around them for cooling

The grease used is probably good to well over 200C, the bearings don't get that hot. No worries there.
last year we were able to mount our victors directly under the CIM motor, the airflow helped keep it cooler. Then again, Lunacy was not hard on the drivetrain.
