@CamaroZL1Guy , welcome to the Community.
HP no longer has the pump or fan available on HP PartSurfer: https://partsurfer.hp.com/Search.aspx?searchText=2HJ35AA
It does list the part # for the complete cooler. You can look for the model # of the fan on the pump and buy one with the same specifications. Otherwise, you will most likely have to buy the complete cooler.
