Questions about this item

Does the fan assembly use the same connector and mounting points as the original DFS5K123043630 part?

Yes, the replacement includes both CPU and GPU fans built to match the DFS5K123043630 part number and the FL05 layout for the listed ThinkBook models.

Will this dual-fan unit fit inside the 14-inch ThinkBook chassis without modification?

The kit is made for the 14S-IWL, 14S-IML, K4-IWL, S540-14IWL and 6Pro-14IWL series, so it aligns with the existing screw holes and clearance in those chassis.

What is the correct order for installing the CPU and GPU fans so the cables reach the motherboard headers?

Route the GPU fan cable first along the rear channel, then seat the CPU fan; reversing the order leaves the CPU cable too short to plug in.
