Proton persona sv 2014.
When on aircond, immediately u can hear the aircond fan is on, u feel slightly more vibrations.
Is it normal ? I remember when my car is new , the aircond fan is loud too, the radiator fan is very very much more quieter.
Any method to reduce the aircond fan noise and vibration ? Can I unplug it? There is still a backup radiator fan.

There is still a backup radiator fan. Unplugging it will risk overheating. Could be a fan motor on its way out or it might be as simple as loose fan motor/fan shroud.

There is still a backup radiator fan. i think is the famous issue for persona and exora. From far i can tell ur ac is running. damn loud.. radiator fan doesnt differ much also. when the engine is too hot. system will still allow the fan to run after u off the engine. On the up side, you get cold air.. no complaint on the ac temp right?

all car like that . persona is best coz its uses 2 fan instead of one , if one broken another will support it. vibration coz engine mounting out and please service aircond not just clean filter change oil compressor . for your FYI exora and myvi more loud than persona

It’s the design fault I guess. I did further observation , the aircond fan is loud and vibrates more than the radiator fan , and the radiator is attached directly to the car frame without mounts and thus we can feel the vibrations in the car.

When only the radiator fan is running , not much noise n vibrations , when the aircond fan kicks in obviously noise started and more vibrations.

I think I better give up lol. Unless I can do some custom modifications like adding mounts to the fan.

Aren't most (if not all) Campro engine Protons have rather loud aircon fans 'naturally'?

i think can change to some quiet radiator fans, or to say the motor of the radiator. just need to find the right size and fitting
