hi all sifus, newbie 1st time overclocking here...i oc'd my sapphire 7850 oc from 920/1250 to 1050/1300 and when i run the msi kombuster and furmark stress tests i get 71' on full load...it's stable over the temp but i was wondering if this is safe for the graphic card? and i set the fan profile to spin at 85% speed at 60'...should i be worried? thank you
