A couple times at Idle, with a depleted battery, I noticed my voltage regulator was getting hotter faster than my alternator casing was, from a cold start.

Last time at ~ 52 amps into battery at 550 rpm, it got upto 125.4F at Idle. That is as hot as I've seen it.

The thermocouple is epoxied to the additional heatsink I epoxied to the underside of the Transpo 540hd.

I do not have the VR under hood, but under dashboard, and ventilation is obstructed.

Enter 60 MM fan.
Might be overkill.
