Hello. Today i bought rx470 G1 gaming. I just installed drivers, start playing BF4 and... ive got a problem. GPU hit 90 degrees after 1-2 minutes nad starter throttling ofc. The same problem in Rust, ETS2, CS:GO. Already tried reinstall drivers after uninstall&DDU old one but it doesnt work. Card hits 95 degrees once and turn off my PC. The only think which help a little was when i set power limit -10%, uv, set max temperature to 84c, and max RPM to 3,7k in Wattman. Now throttling is much lower, but it still is, and card is very loud... and hot. I dont have idea why brand new card getting so hot... spec:
