Hey guys im new here
Decided to add to this..
Yesterday i got my 2600 barton to run stable at 2.51ghz @ 1.80volts
Got some hefty cooling on it aswell.. the heatsink is from a thermaltake silent boost and iv replaced the thermaltake fan with a vantec tornado that i can control the speed of with my akasa fan pro
idle temp with that fan is about...40*c and when im playing games i crank the speed up a bit and the temp duznt really budge to far. Had to stick a little fan on my northbridge chip tho cause i decided it was a bit warmer than i liked (34*c)
For those of u that r unfermiliar wiv that fan, at full speed it spins at 5000 and a bit rpm and shift 80 odd cfm of air

.. can get kinda noisey tho
