Hi there. Can anyone advise on quiet and efficient case fans? I've been running my set-up for a couple of years now (overclocked Athlon etc) but it's so noisy I think that my neighbours can hear it late at night. My current case I bought from Overclock and it has 6 fans on it in total, I'm only using 4 of them (1 on back of case, 1 on processor and 2 on the top of the unit. When checking my CPU temperature only runs at 35c so I am tempted to turn off one of the top case fans or even replace them with quieter models. Any advice or recommendations would be great, I don't really want to buy a new case.
