Andy,
We cannot make blanket statements on removing fans without some additional discussion. Teams may not be able to make the needed calculations to determine heat rise in the devices, air flow through an enclosed space or temperature dissipation in a match. The reality is that each team utilization is different and varies from match to match. Although the FET "ON" resistance is very low (.012 ohm) it still dissipates some heat. Due to the design of the Victor, the case of the FETs are shielded somewhat from ambient airflow so every milliwatt dissipated by the device does not get transferred to the ambient air. Referring to the IRL3103 spec sheet, the junction to ambient thermal resistance is 62 degrees C/Watt. Let's fudge that to 100 C/W due to the fact that the case is partially enclosed, and let's further increase it for the heat rise in the other electronics and wiring inside the Victor and the fact that 6 devices at a time are dissipating the same heat, and I am guessing the thermal resistance has now climbed to at least 150 or even 200 C/W. So as you can see, even small power can raise the junction temperature over a two minute match to a point where the device can no longer suppport even low currents. With the device trying to get rid of just one watt, the junction temperature has exceeded the max temperature specified by the manufacturer. By just calculating the derating factor for temperature the 94 watt max is reduced to 0.2 watts.
I will agree with you that it is unlikely a globe motor would cause an issue in light duty but stall current is still over 20 amps. I feel more confidant recommending teams keep the fans as a blanket statement. It will be the least costly alternative in the long run.
