My only question is since it looks like it is made of metal and the max power is 55W why do they need such a large fan?
A small one moving minimal air should be more then enough to cool it.
Lower RPM to keep the noise down as much as possible?
Still with that size and weight, taking into account the other costs for the components I wonder why they didn't go for more TH, to keep the consumption in check?
Anyhow, let's be happy that those toys are still being produced for fun, I don't think there is anyone planning to make money mining with it!
