do i need to purchase thermal paste, or anything else to assemble in T450s?

Question

Accepted Answer

This cooling fan with heatsink comes pre-installed with thermal paste on the copper cooling block.
You do not need to buy extra thermal paste or other assembly materials to install it on ThinkPad T440S / T450S laptop.
Just remove your old cooling module and mount this unit directly, then fasten the screws and plug the fan power cable.
