Sry, i am a newbie here. I got a gigabyte 8600GT with Zalman fan. When my system is idle, the temperature is 57C and when i run some games, the temperature is about 65C. My question is, do i need to spend extra money to get a better cooler for the card? Or this temperature is enough(don wan my card to burn off when i overclock)

thx in advance

ok thx. I overclock my card, my default core is 600, temperature around 57. When i overclock until like 650, when max load, the temperature is around 72. But now i facing another problem, when i use ATI tools to overclock and scan for artifacts, at 660, it got some artifacts, but, i tried to run 3dmark03 game test 4, it is still smooth, no artifacts. Should i continue to OC? or should i stop and lower it??

ok, thx a lot for the guidance
