Prior to today my G0704 motor would heat up to 140F after running a few minutes at say 1800 RPM in 90F Florida temperatures.
Took care of that with a couple of heat sinks I machined yesterday and a 56 cfm 120 volt pancake. The fan is drawing off the hot air and pulling air through the mill motor. Today the mill has been running nearly continuously for 6 hours in 90F heat. The highest temperature I noted exiting the motor was 102F. I will probably add an additional 4 more sinks for motor next week.
