im on a amd t-bird 1.2 ghz w/ volcano II heatsink, the prob is that the cpu temp is 55C/130F when im browsing the internet and im getting a lil worried. i only want to overclock to 1.33 ghz but i dont know if i should wait till i buy a better heatsink, what do you think?? btw im on an iwill kk266 and it seems petty stable except for a few crashes.
