I want to buy a new heatsink for my cpu. Currently I'm running a AMD Athlon XP 2200+ t-bred (1.8 Ghz). These are the tempature: 40-45 Idle. 50-56 Full Load. The vcore is set to 1.7v, because otherwise I cant run at 2 ghz. I'm running a Thermaltake volcano 7 (copper). Here's my question: Does it cool the cpu better if i use a aluminium/copper cooler? Like this one here ....???
