Fan with part# WG2CK is compatible with R720xd platform. For R720 platform we need to use FAN with part# WCRWR, 3RKJC, WPVP9 or KVN8J. I am not sure about RM4HX. Can you share a picture of part with Dell P/N RM4HX-A00.
I ended up trying the WG2CK fans prior to checking back in with this thread. I observed that while they have the same power needs (12 volts, 1.5 amps), the WG2CK fan units were capable of a higher maximum rpm (~11600) than the regular R720 fans I had worked with previously. It makes sense that the higher thermal demands of the R720xd would require higher CFM rated fans.
I'm currently back to running proper R720 fans.
Thanks for clarifying the part numbers @DELL-Shine K ; I have written them down locally so I can keep them in my toolbox for the future.

I should clarify a bit: the fan itself has Dell P/N RM4HX-A00 while the plastic housing/cartridge has Dell P/N WG2CK
