After installing a case fan, the temperature only goes to 83C if I run it without flags.
Running with -v -w 256 (or 128) gives me a lower hashrate, but also a lower temperature (79C).
Haven't tweaked other settings yet.
Is the CCC power control as good as undervolting with Afterburner or Trixx?
i got the same exact card as you. just use my settings like in the screenshot. use -8% power and well your GPU mhz will vary.
good luck man.
However, it went back to near 90C.
With the GPU clock lowered to 1150, I can do 500Mhash/s in the mid-80Cs.
