Im thinking about changing my hs/f because the 7000rpm fan (actually runs at about 7400) is so noisy. But I had also thought about modding my case and putting in two Sunon 120mm 108cfm fans at 42dba each. Will I be able to hear my volcano 6cu+ over the new case fans, or is it worth replacing it? Im not really happy with my temps either. Athlon XP 1600 on Asus A7V266, 48c idle 53c full load.
