You moved the PC. Different environment means different air flow and temperatures. Check the air flow.
Does it mean that if temperature in room grow for higher,the MHs drop?
yes. also check your OC, 39 sounds like standard clocked or the said thermal throttle. but the bypass still works so driver should be fine.
Use DDU remove drivers, reboot , install drivers should help.
