Is 80-90 degrees @ stock considered acceptable WITH aftermarket cooling?
This is a joke i thought they fixed this with the 290 back in 2013 when i had one but NOOOOOOOOOOOOOO
polaris better solve this or im done for good.
please provide more information about the specific model of r9 390 and describe your systems airflow.
Aftermarket cooling with temps of 80/90o?
Either the Aftermarket cooler is rubbish, you haven't installed it correctly, or you have damaged the chip. The 390 isnt a heat problem card, and I trust these temps are after some time at 100% load right? If so its a little hot but normal for a stock air cooler so go back and reinstall your aftermarket cooler with ample thermal paste on the naked GPU die (as opposed to a CPU with a cap needing very little in comparison, often overlooked). Most likely your issue here.
Polaris will be very light on power, because its a baby GPU.
Perfectly acceptable, anything 94c or lower is safe. If you want lower temperatures, increase the fan speed using Overdrive.
