I have a gigabyte 6600gtvp. I swapped out the old passive heatsink and put a zalaman cooler on with artic silver. It idles around 50 C and gets to 65 C max. The temperatures in my room are about sub 30C (about 70F). Would it be safe to overclock the card and to what speeds are stable. The card came stock as standard 500mHz and the memory is 1100mHz. Thanks
