I see that there are small waterblocks available that use 3mm ID tubing, but I'd prefer to cool the whole board at once with a larger block that can accept G1/4 fittings.
I found that someone was kind enough to upload CAD files for a 2nd gen Pi monoblock here: https://www.raspberrypi.org/forums/view ... 3&t=106079
Can somebody do the same for the RPi 4?
