Sorry, I misread your e-mail yesterday - I thought you're asking why we don't use a case _with_ a fan. The only issue with passive cooling is that we need to make a good contact between UmTRX and a case. And this requires careful selection of a proper case and design of mounting. Again - if you or someone else want to take on this task - we'd be happy use it. > To my knowledge, theres no special cooling considerations taken into > account for any of the USRP's?
