All of the chips in the USRP are specified over at least the 0-70C
range.  At room temperature the USRP can run all-out continuously for
days at a time.  Any enclosure should take the power consumption of the
system into account.  This can be as high as 15-18 Watts depending on
what daughterboards you use.

An enclosure for the USRP will be released some time in the next 2


I run my USRP+DBS_RX combination inside a styrofoam cooler box, in order to stabilize the temperature. With a room temperature near 20C, it runs at about 38C. I run the USRP+DBS_RX more-or-less continuously for radio astronomy applications. In my application tiny temperature-induced gain variations can be a real problem, hence the need to stabilize the temperature.
