Questions about this item

Does the fan arrive alone or with screws and thermal paste included?

The part ships as the cooling fan unit only; mounting hardware and thermal compound are not included and must be sourced separately.

My laptop is a Lenovo X1 Carbon 12th Gen 21KC — which MPN matches it?

Both MPNs 5H41M43389 and 5H41M43388 are listed as direct replacements for the X1 Carbon 12th Gen 21KC and 21KD models.

Will this fan fit the X1 2-in-1 Gen 9 21KE without modification?

Yes, the same fan is specified for the X1 2-in-1 Gen 9 21KE and 21KF, so it installs in the original mounting points.
