ack... the fan noise in my QS800 is really beginning to irritate me; it's louder than the combined 5 fans i have running in my ancient OC'd celeron300A. so i've decided to replace the power supply fan and that giant one inside the case that blows to the side. so i'm wondering if anyone knows the size of those two fans? which fans should i get? i've researched a bit and found panaflo seems to be the favorite among mac mod'ers, but doubt i'll be able to get them here. the other fan is the vantec stealth fans...? so any opinions or suggestions?
