SAPPHIRE R9 290X 4GB GDDR5
21226-00-40G
First of all the noise
omg..,
when fan speed exceeds 65% the noise really is like a jet engine

our 5year old dish washer makes 50% less noise xD

Currently running it @ 60% fanspeed ~3280rpm with household fan blowing into open case and 86c
engine 927 mem 1250 powertune 30 tc 32765
with my asus r9270x-dc2t-2gd5 (464kh/s 73c)

Is there room to improve without getting the fan speed / temperatures much higher?
