Panasonic and KDK are same company and the remote control fans, the PCBs will hum eventually and even if you replace the faulty capacitor, it will only stay quiet for a while then the hum will be back.
My living room KDK is squealing and such so I'm going to replace with a basic regulator controlled fan.
Though honestly I'm tempted to try the Panasonic DC motor fans but will look at the price first.
