I am currently using a dragon orb 3+ to cool my XP 1800+. The idle temps are 38 and at full load it hits 44. My only problem is with the noise. When I'm trying to work on this computer, its unbearable. I am planning on replacing it with the thermaltake AX-7. What is the quietest fan I could get that would keep the same temperatures that I have now? Would a vantec stealth cut it? Thanks.
