i have a r9 390 i am wondering when on idle running two monitors it runs at 60 Degrees celsuis and on full load about 74 Degrees with fans at 58 Percent is that normal? my 380 use to run about 15 degrees lower
Your idle temp at 60c is kinda high. I'd expect more around 40-45 with dual monitors IDLE. Your full load temp is GREAT! My 290x will get into the low 90s when pushed hard. Not to worry though as the cards will throttle if things get too hot.
If you want more specific comparisons you'd need to tell us about your case and fans, which of the hundreds+- of 390 version make and models you have along with your room temperature.
