Once the back-plate screws are removed, there are another 14 screws holding the PCB to the cooler. Three of the screws are smaller than the rest and screw into the motor for the fan. The other eleven screws attach the cooler to the PCB. There are also 2 smaller screws on the mounting bracket that help to secure the cooler. Once the screws are removed, there are 2 plugs on the cooler. The first is for the lighting and the second for the fan. Once unplugged, you can remove the cooler.
The cold plate is a full cover plate. However, it has a plastic cover over it with cut outs for the GPU, HBM2 memory and the power delivery. Speaking of the HBM, or High Bandwidth Memory, its much larger than GDDR5 or GDDR5X memory. There are also thermal pads over the memory and power delivery. You can also see the back side of the motor for the fan. I did attempt to remove the shroud to see the heat sink, but felt I may damage it. It didn’t want to come off.
