Questions about this item

Will the fan connector on this cable need periodic replacement?

The cable uses the original 04X4416 or 04X4117 connector design for ThinkPad L440 and L540 models. It plugs directly into the motherboard header without adapters. No scheduled replacement is required unless the connector pins are physically damaged.

What thermal limit appears first when the cooling fan runs continuously?

The cable itself carries only low-voltage fan power, so it does not impose a thermal limit. The limiting factor is the fan assembly's own maximum operating temperature, which is defined by the ThinkPad L440 and L540 cooling system design.
