Not cooling!

Why did you flake out at only 215? THAT is not hot

What are you running for a pressure cap?

Is it puking coolant?

"Let's talk" about these fans. There is a LOT of junk.

A REAL fan uses a LOT of power They have to have the blades turning the correct direction and THEY NEED TO SHROUD THE ENTIRE CORE

Also, if you are going, say, 40 or better AND ARE NOT running with a 40 mph tailwind, the thing should cool regardless of fans
