a small 5V fan works fine in the Arizona heat.

I just bought 5 of these from Robby. I was running my SD70 and SD45 (MU'ed) on Saturday (at a reasonable 50-60% speed) and after about 5-10 minutes the LM-4S-G modules overheated. The conditions were direct sunlight, 88*f, high humidity. I even shortened the train from 35 cars down to 25, turned sound off, slowed the train down, etc. Still got the module overheat warnings on both locomotives. I'll try to remember to report back with the results after installing these and when I run them again in similar conditions.

FYI, here's the link to the manufactures page for this item https://www.ovrailcar.com/online-store/Rail-Pro-Bracket-Mount-with-Fan-and-Heat-Sink-p376391580

Preliminary results: I installed one in my SD70 that was overheating badly (the USAT motors pull more current than Aristo, so I figured it would be a good locomotive to test first). 90*, cloudy, 50% humidity. I ran it by itself at 100% throttle for about 15 minutes. Albeit not the same conditions as this past weekend (not pulling a load, not sunny), the temperature hovered right around the "GOOD" line on the controller. I even grabbed onto the coupler for a good 30 seconds at a time to shoot the motor current up, did that quite a few times. The temp still stayed around the "GOOD" line. More to come when I have an opportunity to run it on a hot sunny day, but so far it seems promising that my overheating woes will be solved with this thing.
