Yep. Lots of places just let them idle to heat up the oil.
I don't have heater ducts so all of the fan-blown air is passing right by the engine.

And as I'm still shaking bugs out of my tune, it idles ~1100. So it moves a bit more air than idling at 900.

Thanks for the data points. That's a big help.

As my own data point, with the CHT sensor where I've placed it, I've never seen CHT temps above 75C. Not with idling, beating on it, or highway cruising.
