Spray a water hose on the condenser when the pressures are high. Does it drop like a rock?

Are the replacement fans OEM or aftermarket? Just replaced my cooling fan with a very good quality OEM supplier aftermarket (definitely not Chinese rubbish) and that solved a comp noise issue i used to experience for good. Can now feel a lot more airflow with the hood open than before. Quality control is critical with these parts.

You need to be careful with aftermarket fans. Some of them allow you to wire them in reverse rotation. Some of them mount with different types of mounting that will allow them to rub on the condenser and radiator. Some of them do not have the proper CFM ratings. SDometimes you are better off biting the bullet and getting the OEM fans.

Don't know why all OP posts disappeared at once, but my brand new cooling fan unit is marketed by Valeo and equipped with a made in Spain Nidec Corporation (Japanese company, likely OEM supplier) motor. Don't know what kind of motors OP's brand uses either.

Might be from the recent attempt to update the forum software. IT got an error so reverted back.
