I will suggest the Arctic Freezer Pro CPU kooler.... it costs 12 Euros so quite a steal. At least if this is not your main rig, this should do the job quite superbly. Unless you want to hit higher than 500 FSB with higher than 1.5V on Core 2 Duo, this kooler should do the job. My personal opinion has always been invest in a good decent cooler but dont go overboard, rather go to a higher processor in that case.... So I would definitely prefer a E6600 with Arctic freezer Pro rather than a E6300 with Tuniq if you see what I mean....
