If you typically stall your motors for 5 minutes at 50 amps, then temperature might be of concern.
The stalling doesn't matter as much as the current; IIRC the heat generated is proportional to current.
I would be worried about getting a burn or burning something at that temperature. Plus, CIMs often run at high currents for the duration of the match; it's certainly possible to average 40-50 amps for a match.
