Recently I put arctic silver 5 on and I was able to overclock to 2.8 ghz (probably couldve before) but I learn more and more everytime I read about it. Anyways, I got arctic silver, and a zalman 7000 cu led heatsink. I idle at 35c at 2.8 ghz (1.57vcore) but its not stable cause cs freezes very fast after loading. I want to know if i buy a new heatsink (cps9500, big typhoon, or the scythe ninja, would it lower my idle temp? I dont think it would, But im not sure, so thats my main question, If i upgraded, would i get a lower idle temp + be stable? Thanks guys.
