UNSOLVED
successful conversion of XPS 730X H2C cooler to Dell air cooler
prerequisite: acquire a chipset air cooler
unplug H2C power from MCB
remove the entire H2C and motherboard from case (easier to dissemble outside case)
unscrew heat spreader retainer screws on back side of mobo
detach H2C along with heat spreader from mobo
use small flat blade screw driver or a blunt tweezer to gently pry the H2C chipset cold plate from the chipset heatsink
reinstall heat spreader pipes to mobo
install chipset air cooler
reinstall mobo in case
apply front cpu shroud and Dell air cooler to cpu
Dell thermal control app automatically detects H2C is gone and new cpu cooler present

reusing XPS 730X H2C on LGA115# socket or LGA2011 socket, is it possible?
LGA2011 is definitely possible. user had validated it. I think it uses M4 studs to mount on LGA2011 socket which has built in M4 nuts.
remove Dell LGA1366 mounting screw and screw holder. you are left w plain liquid pump slots for new mounting hardware.
The chipset cold plate would not be installed. it would just hang in free air.
benefit of H2C is lower noise controlled by 730X thermal control.

by the way
Assembly,Carrier,Theater Lightning,730X. $29.99 This is a part often hiding corroded AA batteries and making it difficult to clean.
It is possible to rewire the 3V DC power from 2XAA batteries to a spare 3.3 V of sata power line, thus eliminating the need to use 2AA batteries and avoid battery corrosion issue down the line.

H2C was working prior to conversion, but was afraid it might leak or break down one day. do not want to face a headache down the road. change to air cooler now. easier to upgrade to modern mobo cooler later on if plan to go down that path.
