noisy fan and engine vibration

2011 328i E93

With the air con running, the cooling fan is loud all the time. With the air con off the fan is very quiet. But...also, the engine has a vibration at 1500 rpm with the air con on and no vibration with the air con off.

What gives here? Simply the fan having issues? Or more?

No codes, no overheating. Coolant flushed and renewed and the problem was same before and after the coolant flush. And yes I have the correct coolant.

Thnx
