TSUJ Kepler-C72J-OYS-0394 4010 Cooling Fan

This TSUJ 4010 fan provides silent cooling for compatible 2-in-1 laptop accessories. It operates on a 12V DC supply and draws 0.8W of power. The three-wire design supports speed monitoring for system management. Buyers needing a different voltage or a four-wire PWM connector cannot use this model.

Straightforward 3-Wire Installation

The fan connects via a standard three-wire header for power, ground and tachometer signal. Polarity must be observed to avoid damage to the unit or the motherboard header. The compact 4cm frame fits tight internal spaces but offers no mounting screws in the package. Builders without a spare 12V header or suitable clearance should verify compatibility first.
