I just recently built myself a system. It has the 2600 mobile, abit nf7-s v2, and ocz 3500 2.5-2-3-11, right now, core voltage is 1.65 with 200x12. I have a zalman al-cu flower heatsink on it with artic silver 5. My power supply is an antec 430 true power. My ambient case temp is 35C and idle the cpu is 50C. My case has 2 120mm fans. I can't figure out how to get the temperature down.
