✅ Confirmed Compatibility

Compatibility applies only to systems whose original fans carry both exact ND part markings and DC 5V 0.50A labels. A model-name match alone is insufficient because multiple fan revisions and voltages exist within this chassis family.

⚙️ Fit Notes

• These fans are side-specific and are not interchangeable with each other.
• ND55C99-21A08 is the CPU-side fan. ND55C0A-21A09 is the companion fan commonly marketed as the GPU-side fan.
• “GPU-side” is a positional marketplace description. This platform uses integrated graphics and does not require a discrete graphics processor.
• Confirm both original fan labels read DC 5V 0.50A. Do not install this kit in a system equipped with 12V fans.
• Compare the connector keying, wire order, cable length, mounting tabs and blower outlet shape before installation.
• N12234-001 is the complete fan-and-heat-sink assembly. This listing includes the two loose fans only.
• Not interchangeable with L36046-001 used in the older 13-AE platform.
• Not interchangeable with M22180-001 or M22181-001 used in the earlier 14-EA platform.
• Do not substitute N47948-001, N49282-001, EG50050S1-CM50-S9A or EG50050S1-CM60-S9A; those belong to different 15-FE and 15-FH platforms.
• Disconnect external power and the internal battery before servicing the cooling system.
• If the heat sink is removed, clean away the old compound and apply fresh thermal grease before reassembly.
