I've been trying to find out alittle about OC'ing this old system to get more out of it. Looks as though I cant OC my processor, but I have downloaded ATI tool, and it seems I may be able to OC my ATI X1600 PRO AGP 512 MB card. Still not sure how yet, but my first problem is heat. It's running hot at Idle so I am looking into cooling it before I start OC'ing the card. I can place another case fan to move more air, but I am looking into card coolers. Any good suggestions? I have looked at two online so far.. Arctic Cooling ATI VGA Silencer 1 ( rev.2) Zalman VF700-CU Copper VGA Card Cooler. I dont think Iwant to go to water since this old system will only be around another year before I go custom built. any suggestions on a cooling unit?
