Internal Cooling Fan (Jamicon JF1238B2HR-R)
The internal axial fan uses ball bearings that can develop axial play or lubricant breakdown over high-duty cycles, leading to rotor imbalance. Because the fan is hard-mounted to the steel chassis, these mechanical eccentricities translate into an audible rattle against the housing. Replacing the fan restores the mechanical balance of the cooling system.

Victron Fan PWM Retrofit Kit
This kit is an official OEM engineering fix designed to dampen the PWM signal frequency that controls the fan speed. On older units, the PWM frequency causes the fan motor to vibrate aggressively at low RPMs, which can be interpreted as a rattle or high-frequency chatter. Installing this kit addresses the electromechanical root cause of the vibration.
