I have a rock 5b and even at idle it puts out a pretty impressive amount of heat. I’m running the passively cooled case from radxa and while I don’t encounter any slowdown I can’t possibly imagine the uconsole case shedding enough thermal energy, or holding it when the 3588 is really humming along, it’s a beast.
I have a banana pi cm4 with an amlogic a311d (6-core 2.2ghz , Mali gpu) that I have tested inside the uconsole. I haven’t figured out how to patch the kernel for the display but even that gets hot to the touch and uncomfortable when using over hdmi.
I’m not here to tell you it’s not possible or anything but I’ve just abandoned my efforts personally for a rk3588 and decided to enjoy the cm4. Even over clocked to 2ghz it doesn’t get anywhere near as hot as the a311d, so I can’t imagine the 3588.
If it’s something you want to pursue there are 3d printed backs with a LiPo battery and a cutout for a HSF.
