i have an athlon xp 2000+. i have been using a volcano 6cu+, and it has been cooling ok, but the thing is really loud. i do have lots of fans in my case, but i tried unplugging most of them and the sound didn't change much. is this the reason for my noise problem? if so what is a good heatsink for this chip? i would like something that isnt too cheap but i dont want to spend too much. thanks for any help
