Direct replacement for Inspiron 14 5485 and 15 5585
This genuine Dell OEM motherboard carries the FNM6F part number and fits both the 14-inch 5485 and 15-inch 5585 chassis. It ships new with an integrated AMD Ryzen 5 3500 quad-core processor clocked at 2.1 GHz. The board is intended for owners restoring a failed unit or technicians performing board-level service on these specific models.
Sustained workload behaviour
The soldered Ryzen 5 3500 and built-in Radeon Vega graphics share the same thermal envelope, so clock speeds settle to a steady state under prolonged compute or media tasks. DDR4 memory support keeps data throughput consistent during extended multitasking sessions. The fixed CPU configuration means performance ceiling is defined by the 3500 silicon rather than a replaceable module.
Thermals, noise and power draw in normal use
Cooling performance depends entirely on the original laptop fan and heatsink assembly attached to this board. Power consumption follows the 3500 TDP profile, so battery runtime and acoustic output remain comparable to the factory configuration. No additional power circuitry is present beyond the standard Dell implementation for these Inspiron platforms.

คำถามเกี่ยวกับสินค้านี้
How much heat and power draw should I expect from the Ryzen 5 3500 running at 2.1 GHz all day?
The integrated Ryzen 5 3500 quad-core processor at 2.1 GHz is designed for efficient everyday workloads, and the motherboard's thermal layout matches the original Dell Inspiron 14 5485 and 15 5585 cooling solution.
Which existing parts from my Inspiron 14 5485 or 15 5585 must I reuse for this motherboard to work?
You will need to keep your DDR4 memory modules, display panel, keyboard, trackpad, battery, storage drives and chassis, as this board only replaces the main logic unit with the soldered Ryzen 5 3500 CPU and Radeon Vega graphics.
Will my current DDR4 RAM and M.2 SSD work without changes on this replacement board?
Yes, the board uses the same DDR4 memory slots and storage connectors as the original Inspiron 14 5485 and 15 5585, so your existing RAM sticks and M.2 drive will be recognised immediately.
