What White Ice said. Plus, if you use the B connector they can cool the bike after you turn it off. If you're worried about it running too long when you park the bike, you can always flip the switch on the fan unit itself to turn it off.

Head temp and oil temp are 2 seperate measurments (don't confuse them).
I have the wards fans, they work, I have the temp switch it turns on at 185degrees cylinder head temp and shuts off at the same temp. The fans run for maybe 1 minute after shut down to bring the bike to 185 degrees head temp, then with heat soak the heads will get back over 185 and the fan comes on and shuts off, usually a 2 cycle for me here in MA. No issues with battery drain.

Yeah, I get that, and I'm not confused but since you brought it up, what is your oil temp at when your heads are 185 out of curiousity?

I do not use the Wards cooling fan, but have the HD Parade fan.
It has the thermo switch mounted to the inboard side of the backing plate of the
Air-cleaner. It worked great for the first couple years .The fan only would come on if I was sitting in +70 degree weather and ideling for more than 5 minutes (traffic jam or Border lines) the thermo switch does work.
I broke a wire and decided to put a switch in and have no problems forgetting if it is on or not.
Two different fan types and two different opinions.

If some of you think that flipping the switch on and off is the way to go, then have at it. You will likely heat damage your fans over time, put excessive wear on the mechanical switch, and disallow the fans to operate at their maximum potential.
The Thermal Switch is $20 shipped. A moron can install it. (like me!)

it depends, I have a 10 row oil cooler also, usually my oil temp never goes above 228 degrees, the fans have turned on at 200 degree oil temp, but have had them cycle on and off at oil temps 220-228..

Perfectly normal. Head temps and oil temps are different at any given time you want to measure them. The fans cool the heads. Sounds like the thermal switch is doing it's job well. It's very normal for the fans to run while riding down the road when ever your head temp reaches the turn-on temp which is around 185 degrees plus/minus a few degrees.

I bought the switch with the intention of using it, but thought that keeping the heads cool would be a better scenario than waiting until they come up to 190 degrees. If not, i'll install that switch tonight, I know it's a breeze to put in.
