^ what Ecky said. I want to have control over when the car is shut off and when it is not, and not have it just randomly autostop on me in the middle of an intersection or when I'm not prepared for it.

----------

Ordered an Arctic F9 92-mm fan for the Meanwell and some thermal paste for getting it permanently mounted. Plan is to mount the meanwell on it's side once the new fan is installed.

Meanwell shuts off below 900 RPM most of the time, and with a moderate load shuts down below 1000 RPM, and with a heavier load shuts down below 1100 RPM. Car still starts fine even if the meanwell is off for a while. I did some driving on dirt roads and around some mobile home parks today at slow speeds in 4th gear right around 800-850 RPM (getting over 100 MPG) with the meanwell off for about 3 miles/10 minutes. Voltage didn't really drop much so no big deal. Even with the occasional times when the meanwell doesn't power on my 12V battery is staying charged much better than with the stock DC-DC.
