Just clariying, you have one fan that never runs, and you have one fan that runs with the A/C on or while the engine is cooling off when hot.

Questions:
1) Does the fan run fast with the A/C on, or slow? Fast = very noisy, slow = somewhat less noisy.
2) Does the fan run fast with the engine cooling down, or slow?
3) Or does it run at the same speed, and you can't tell if fast or slow.
4) With the hot engine off, A/C off, and the fan running in cool down mode, turn the ignition on.
a) Does the fan speed up?
b) Does the fan stay the same?
c) Does the fan stop.

This info will help pin down the problem.
