Griffin radiator and twin fans still running at 190-200?

I think mine is 65. Chrome alternator. If I have issues I will just trade it up for a 100 amp version. I will keep posting here until I get it right and let you guys know what I find. I fixed the battery negative cable so tomorrow I am going to go for a short cruise and get a new inspection sticker. So that will be the maiden voyage with the new radiator and spal fans. Hoping it will surprise me. Spal told me that the sending unit I have is 185 degrees on and 165 degrees off. They have a higher one as well but they told me it is better to have them running constantly while the car is running. So I guess it will never see the 165...

The information you're getting from SPAL is pretty interesting, and not in a good way. It's not better to have the fans running all the time. They should cycle on and off as needed, and they shouldn't be on at all when you're maintaining a constant speed that's much faster than 30 mph. The radiator should be able to handle that without the fans in most conditions.

To me, if the fans are running all the time it either means the radiator is too small or the fans don't put out enough CFM. You should be able to have the fans kick on at 200, cool the car down to 185, then shut off. If you're cruising, they should be able to stay off and the radiator do the work. The whole point of the electric fans is that they aren't running all the time, you're not wasting power driving a fan that you don't need. You should be able to set them to maintain the operating temperature you want, so the car stays in that range.
