Four-line connector for ASUS notebooks

This internal power cable uses a four-line connector designed for ASUS A40J, A42J, A42JR, A42JV, X42J, K42J, P42J, K42JR and K42 series notebooks. It links the motherboard to the CPU cooling fan and radiator assembly. The part is supplied new and matches the original pin layout for these models.

Connector restores cooling function

The four-line interface carries both power and speed-control signals so the fan can respond to thermal load. Without the correct cable the cooler cannot operate, leading to overheating or boot failure. This cable replaces a damaged or missing original and restores normal cooling operation.

Questions about this item

How often should the 4-line fan connector be inspected for dust buildup?

Check the connector and fan blades every few months; compressed air removes dust that can restrict airflow and strain the motor.

What typically limits continuous cooling performance first?

Dust accumulation on the heatsink fins reduces airflow before the fan motor reaches its thermal limit.
