We plan To run the Odrive continues at around 100A. Do anyone have any suggestions on water cooling which can be used on the mosfets?

I would suggest to try air cooling first, because you will need airflow over the board anyway even if you watercool. The reason is that a lot of heat is conducted into the PCB copper polygons from the FETs.
That said, should you really want to watercool anyway, I would recommend something like this. It’s a little bigger than would be ideal, but it’s what I could find.
You can zip-tie it in this orientation:
Thanks @madcowswe!
So a combo would be a good solution? a watecooling block + a small fan for the pcb?
But I will look for something smaller than that
Water cooling the epoxy would be a bad idea.these mosfets are designed to be cooled from the metal plate underneath instead of water cooling from above.
And you will not have a good result bcz epoxy is not a good conductive of heat.
My suggestion:
find better mosfet in the same package or design pcb to use to247 or to220 mosfets.
Hi all, maybe you could try this
Thermoelectric Peltier Refrigeration, maybe better than a huge block of Aluminum
