I'm thinking of saving a few bob and getting an oem venice 3000 instead of the retail - lowestonweb do it for £82.29 delivered. versus most prices for the a64 3000 retail that saves me £25. What would be the best cheap heatsink and fan to go with this processor if i want to overclock it to around 2ghz - 2.2ghz? It must be quiet as well - below 28db! Anyone?
