I bought the OEM AMD Athlon 3200+ Venice that comes with a heatsink and fan. The fan is really loud I want to replace just the fan. But what size is the fan? 80mm? I am guessing that's what it is. I was looking at the XP-90, but that thing costs like ~$35 + quiet fan and I will also need to buy the thermal paste remover. So it's gonna run me up about $50. So I will just give this fan thing a try.
