Seeing is believing - but I don't know what you hope to accomplish anyway. A clean and functional a/c system won't reach the threshold for fan operation at cruise unless something is terribly wrong with it. Off and your static pressures don't usually exceed 100 psi. Most of the old ones don't reach pressure because the juice is gone. The rebuilt and new function as advertised and your coolant temps are cooler (at idle) because you don't make cold air if you let the high side gyrate out of control (which will overheat the coolant). A/c is relatively simple and safe - until you start monkeying with pressures. That's when some end up with a hole in the hood - others get seriously hurt.
