If you go into Afterburner you can see the Fan Speed (%) slider just below the Memory Clock slider. Make sure it is on AUTO (click Auto button it should show a green light).
Then click Settings > Fan > TICK "Enable user defined software automatic fan control".
Change the graph to make your GPU fan run at 100% from around 60 c
I have mine on a gradual climb from 50% to 100% fan speed between 40 and 60 c
I also changed another setting which may help if the PSU is unstable at high temps. Go back one window to the General tab and under Safety Properties tick "Force constant voltage".
These haven't totally stopped the reboots but I can now play for at least 15-20mins without any problems. Last night I played for around 30mins and didn't have any reboots.
Hope this helps
Adam
