Lenovo ThinkCentre M.2 2280 SSD Kit III — 4XF1C39743
Mounting hardware, not a driveM.2 2280Heatsink + carrier + stopperGenuine Lenovo option
The Lenovo ThinkCentre M.2 2280 SSD Kit III, option part number 4XF1C39743, is the mechanical hardware that turns an empty onboard M.2 slot into a usable one. Lenovo ships several ThinkCentre and ThinkStation models with a second M.2 2280 position on the board but without the parts that hold a drive in it, and this kit supplies exactly those parts: the M.2 2280 heatsink assembly, the carrier that sits underneath the drive, and the M.2 bracket with its stopper. It is a genuine Lenovo option, so it lines up with the factory mounting points instead of being improvised. What it is not is an SSD — the drive itself is a separate purchase.
Compatibility — check before buying:
This kit contains no SSD. It is the heatsink, carrier and stopper needed to fit an M.2 2280 drive into an empty onboard M.2 slot on a supported Lenovo system — the drive is bought separately. Lenovo’s own documentation shows 4XF1C39743 as the M.2 heatsink and bracket part for the ThinkStation P2 Tower, P3 Tower, P358, P360, P360 Ultra, P340 Tower and P340 SFF. For the ThinkCentre side, Lenovo describes the option only as being for “selected ThinkCentre and ThinkStation” machines and publishes no model list, so we do not print one. Two further points that change an order: the heatsink assembly is documented as supporting one-sided M.2 drives, so a double-sided module is outside its stated support; and it fits 2280 only. Send us the machine type of your system — the four-character MT code on the label — and we will check the slot and the kit against Lenovo’s parts list before you order.
Best For
✓ A supported ThinkStation or ThinkCentre with a bare second M.2 slot
✓ Adding a second NVMe drive to a factory single-drive configuration
✓ In-warranty machines where a genuine Lenovo option is preferred
✓ Fleet upgrades that must match Lenovo service documentation
✓ Replacing a heatsink or stopper lost during a previous service
✓ Workstations where a bare M.2 drive would otherwise run unshielded
Key Features
The parts the slot was missing
A bare M.2 slot on a Lenovo board has no retention hardware and no heat spreader. This kit is what makes the slot usable: the 2280 heatsink and its carrier, the lower carrier component, and the bracket with stopper that locates and retains the drive. Lenovo’s own service instructions call the kit out by this part number.
Genuine Lenovo, so it matches the chassis
Third-party heatsinks are sized for a generic motherboard, not for the airflow path and clearances inside a ThinkStation or ThinkCentre. Because 4XF1C39743 is the option Lenovo lists against these systems, it seats on the factory standoffs and clears the surrounding components without modification.
Passive cooling for the added drive
The kit is mechanical and passive — a heatsink assembly, not a fan. An NVMe SSD dropped into a bare slot with nothing on top of it will throttle sooner under sustained writes; with the heatsink fitted, the drive has a metal path to shed that heat into the case airflow. Note that Lenovo documents support for one-sided M.2 drives.
Technical Specifications
Frequently Asked Questions
Singular Expert Insight
The trap here is the name. “M.2 2280 SSD Kit III” sounds like a drive and is not one — it is the bracket, carrier and heatsink that a factory-empty Lenovo M.2 slot needs before any drive can be fitted. Order it together with the SSD, not instead of one, and check that the drive you pick is a one-sided 2280 module. For the drive itself, our internal SSDs range covers the M.2 2280 NVMe models that go in this slot, and if you are weighing an internal upgrade against simply adding capacity outside the machine, the external SSDs section is the alternative that needs no kit and no disassembly at all.
Buyer’s Guide
Buy it if
Your ThinkStation or ThinkCentre has an empty onboard M.2 2280 slot with no heatsink or stopper fitted, you want the genuine Lenovo option rather than a generic bracket, and you are buying the SSD alongside it.
Skip it if
You expected a drive — there is none in this box. Your M.2 slot is already populated and has its hardware. Or your intended SSD is double-sided or a length other than 2280.
Also consider
An M.2 2280 NVMe SSD to go with it, or a generic M.2 heatsink if your machine is not one of the systems Lenovo documents for this kit and you only need cooling rather than factory retention hardware.
