Yup... I even pulled the wiring apart today to make sure I was using the high speed winding. And I was......

It has been really hot here, but this thing ran these temps when it was cooler too.

It's definitely pulling heat out of the rad. The controller works as advertised. It comes on slow speed until it heats up, then it runs on high. It never wavers off high speed though, since I have the cut in speed set for 180 or so, and it isn't able to cool it down that far.

As I said, regardless of thermostat rating, no thermostat etc., it'll run 195 all day sitting still. It's when it's moving is when it creeps up. Exactly opposite of what it did with the mechanical fan. Even the low/high temps are the same! Today, I got caught in a thunderstorm, and it was POURING (my poor car!) and it ran at 195 during the rain. As soon as it stopped, it crept up quickly to 210. I pulled in my driveway, let it idle a minute, and the temp was coming back down.

Mixture is good too (I run an LM1 all the time). I have to recheck my timing...... although the odds of it slipping at the exact time I changed the radiator and fan is like winning the lottery.
