That's one of the things we were discussing last night with a few other owners at the car show. It can't hurt anything to drive the water pump a little quicker.

Electric Fan is cranking in the right direction, it blows air out the back on the driveway and will suck a paper towel in the nose up against the radiator.

It will cool 3-5 degrees briefly by revving the idle. Then it continues to climb. One thing to note about the flow. Let's say I heat it up to 100C, then shut it off but leave the electric fan on. After about 3 minutes of the fan cooling the radiator if I start it, it immediately drops down 10* as it sucks the cooler water in out of the radiator. I can kill it, wait a couple minutes and do it again, and I can get from 100* down to 80* in 5-7 minutes like this. So I think that suggests I am getting good flow, no?
