or u can get those PSU with temperature controlled fan, so that when the load is low, the fan in the PSU will automatically spin slower to reduce noise.
there is a brand call be-quiet...the fans actually will carry on spinning for 3 minutes after shut down, this is to remove the heat in the casing quickly to lengthen the life of the components
my superflower psu is temperature controlled with manual speed override, even on low speed its noisier than my gigabyte cpu cooler, so i think brand matters and i chose the wrong brand/model... any recommendations on locally available ones welcome.
