my friend has it. If i recall correctly, it even does a better job on cooling than its bigger brother aero7 non lite (all copper), because bigger heatsink albeit it's aluminium. The fan might be a little loud, but at medium setting (around 3k rpm) it sounds like default amd fan, maybe quieter. For the temp, it's great, but definitely not a competitor to zalman, slk, etc. But for cheap fan it's not bad. You may want to google it to find some review, i remember seeing several reviews about this fan.
As for your 2600 chip, you must try it for yourself. If it's mult locked and not a mobile chip, maybe your barton mobile will do better. But if it's mobile barton, it might be a potential overclocker
