  • On-board 1.7 GHz Core i3-4005U dual-core processor integrated
  • Discrete Nvidia graphics built onto the system board
  • Exact-fit part number K2WKN matches factory specification
  • Ready for 14-inch chassis with Nvidia graphics configuration

Genuine Dell OEM replacement board

This motherboard is a genuine Dell OEM system board carrying part number K2WKN. It integrates an Intel Core i3-4005U dual-core processor running at 1.7GHz alongside discrete Nvidia graphics. The board is built specifically for the Inspiron 14-3458 laptop chassis.

Sustained workload behaviour

With the soldered 1.7GHz Core i3-4005U and discrete GPU sharing the thermal solution, clock speeds will settle to a steady state under prolonged load rather than holding peak turbo. The dual-core design handles everyday multitasking and light content tasks consistently within its power envelope.

Thermals, noise and power in normal use

The laptop cooling assembly manages heat from both the CPU and discrete graphics, so fan activity rises smoothly as combined load increases. In typical office or media use the system runs quietly, drawing only the power needed for the integrated processor and dedicated GPU.

Questions about this item

How loud and hot does the K2WKN board with its on-board 1.7 GHz i3-4005U get during all-day use?

The board uses the original Inspiron 3458 cooling design, so noise and heat stay at the levels Dell engineered for this 14-inch chassis.

What existing parts from my Inspiron 3458 must I keep to make the K2WKN motherboard work?

You need your original display panel, keyboard, battery, AC adapter and bottom case; the board includes the CPU and discrete Nvidia graphics already soldered on.

Will the K2WKN board fit and run in my older Inspiron 3458 that currently uses integrated graphics only?

No — this board is built for 3458 models that shipped with discrete Nvidia graphics, so it will not match the integrated-graphics chassis.
