@Bruce.Qin, would it be possible to add the fanless heatsink to the store as well?
There are situations when one would want a fanless SBC instead, but needs the 64 GB eMMC version. See here for instance: Spare vanilla fanless heatsink for Odyssey X86J4105
I know the fan can be disconnected in the fan version, but the heatsink is smaller and won’t be as efficient with fan off as the true fanless version.
