Direct Replacement Board

This motherboard is a genuine Dell system board built for the Inspiron 14 (3458) laptop. It arrives with an on-board Intel Core i3-4005U processor already soldered in place. The part is intended for owners who need to swap a failed board in that exact model. Matching the Dell part number PX1X6 before purchase is essential.

Sustained Thermal Behaviour

The integrated CPU runs at a base frequency of 1.7GHz and shares the laptop's cooling assembly. Because the processor is fixed to the board, thermal performance depends entirely on the original heatsink, fan and chassis airflow. Under continuous load the system will throttle according to the factory firmware limits designed for this 14-inch form factor.

Integrated Build Practicalities

All core logic and graphics are embedded on the board, so no separate CPU socket or discrete GPU connector exists. Replacement therefore means transferring the existing memory modules, storage drives and wireless card onto the new board. The layout matches the Inspiron 14 (3458) mounting points and I/O cut-outs exactly, allowing a straightforward swap when the part number is verified.
