Mac Pro 4,1 Liquid Cooling Plans :)

I'm looking to trade my Hackintosh in for a real Mojave capable Mac for the peace of mind it will bring. I have bought a 4,1 and a Xeon X5680, I plan on transferring over all my RAM sticks and my GPU...However, any computer I own absolutely must be liquid cooled come hell or high water (no pun :p)

Now I Have been looking for ways to do this from pictures alone and at first it looks exceptionally difficult as the MOSFET's are cooled via the stock heatsink assembly as is the CPU Northbridge, also I suspect that if the Mac doesn't detect the temp sensors and integrated fan it might throw a wobbly upon boot, and the Mac Pro uses custom hole spacings... however I believe I have come up with a solution that satisfies all these criteria, is simple, and requires no custom mounting hardware.



As can be seen, the standard heat-sink module already contains a Mac-Pro CPU mount, it also contains an integrated water block of sorts and a MOSFET cooling block, my plan is to separate the thick solid bottom mount from the heatsink assembly on top of it, remove the heatsink fins then cut down the copper heat-pipes. then attach neoprene tubing to them and run all three pipes in parallel to a reservoir and radiator elsewhere.

Here is the amount I am planning on cutting of the top of the Heatsink to gain access to the heat-pipes.

Do you think this sounds like a viable method for water cooling the Mac Pro?
The only thing I'm worried about is that the heat pipes terminate in the middle of the Copper block and don't pass straight through, other wise the heat-pipes will have excellent water-cooling abilities due to the rough porous surface inside of them.

Yeah I read one, I didn't see the other two, I'm on the fence where this is concerned due to the heat-pipe situation, If the heat pipes are continuous then I will 100% do this and spice it up with a 3D Printed sleeve etc but I have to find out first before potentially destroying my only cooling solution for my computer, going to see if any are for sale in the UK.

Brilliant I'm seeing they are on sale for £20 :)

If you want to go liquid cooling and willing to mangle the heatsinks, maybe it would make sense to just do a custom case and try to get enough sensors and such so it doesn't yell?

It would be interesting to see a cMP submurged in something like Novec.

Thats the exact reason I'm doing it this way, with this method I'm able to leave the sensors on the existing mount. I would love to see that though.
