Hi Vanush, turning the device off sounds like an odd solution for a temperature problem. Also, usually you're experiencing frequency drift with temperature, which can, if your receiver architecture can't correct, will lead to degraded SNR.
Thermal noise will only significantly increase if the temperature shift is not negligible compared to the effective equiv. noise temperatures of your system, which /should/ be dominated by the first amplifier stage. So if I'd suggest anything, it would be just adding a cooler/fan/peltier element to that, and see if your performance measurably increases, just to verify it's a temperature problem at all.
