Genuine Dell OEM Motherboard with Soldered i3-4005U

This is a genuine Dell OEM system board carrying the Dell part number 27C5F. It arrives with an on-board Intel Core i3-4005U processor running at 1.7 GHz and integrated Intel graphics. The board is built as a direct replacement for the mainboard inside specific Inspiron laptops. It suits repair technicians or owners restoring a failed unit to working order.

Sustained Thermal Behaviour in Thin Chassis

Because the processor is soldered directly to the board, thermal performance depends entirely on the laptop's original cooling assembly and fan curve. Under prolonged load the dual-core chip will throttle to stay within its designed envelope, so clock speeds settle below the 1.7 GHz maximum. The integrated graphics share the same thermal budget, limiting extended 3D or video workloads. Expect stable operation for typical office tasks but reduced frequencies during continuous heavy use.

Direct Replacement for Inspiron 14 5458 15 5558 17

This motherboard replaces the original system board in Inspiron 14 5458, Inspiron 15 5558 and Inspiron 17 5758 models that shipped with integrated Intel graphics only. It will not fit variants that use discrete graphics or a different part number. The upgrade is worth it when the existing board has failed or when a verified 27C5F board restores full function at lower cost than a new laptop. Buyers needing discrete graphics support or a different CPU cannot use this part.

Domande su questo articolo

How much power does the on-board i3-4005U at 1.7GHz draw during sustained load in an Inspiron 5558?

The i3-4005U is a 15 W TDP processor; the motherboard's VRM and cooling are designed for that thermal envelope in the listed chassis.

Which existing parts from my Inspiron 15 5558 with Intel graphics must be reused for this 27C5F board to work?

You will reuse your display panel, keyboard, battery, storage drive, memory modules, wireless card, heatsink assembly and bottom case.

Will this 27C5F board fit and function in my older Inspiron 14 5458 that currently runs an i3-4005U with integrated graphics?

Yes — the 27C5F is a direct replacement for the 5458, 5558 and 5758 models when they are equipped with Intel integrated graphics.
