So, in brief, 53 pages of hope, sweat and tribal dancing is ended like ROI=never.
ESP when this is what the community will have to perform to get these specs. This is a a bad dream I think.
From the link
Advanced Modifications
Soaking the heat sink in isopropyl alcohol overnight, then removing it
Removing the 6 power inductors on the board and replacing them with bigger versions with the same footprint
Desoldering the fan connector on the PCB and adding an 8-pin PCIe power connector
Adding a small heat sink to the back of the board on the LTC3884 chip
Adding a heat sink to the 6 inductors
Mounting an air blowing fan to cool the LTC3884 and the inductors
Cutting a custom copper plate from stock metal, and using SAC305 solder paste to solder it to a Thermaltake water cooling block using a toaster oven
Modifying (drilling/grinding) the stock Thermaltake water block mounting hardware to fit the VCU1525 mounting holes
Applying either Arctic Silver 5, or Conductonaut Liquid metal (gallium) to the VU9P die and mounting the water block
Building a 360mm radiator mounted with 3 x 120mm Antminer class fans
Completing the water cooling loop with a Noctua manual fan controller and water pump/hoses
So I dont think I would do this to a 300$ card let alone 4k$. Just to let you know. I could perform these task. But do I want to hack a board to that degree to make it work. How about designing it right from the get go.
