beware, those fans (at least the first one) are 30 dba, which is very noisy. you may want to have a look at other ones... i don't know much, but choose one between 21-23 dba. also check cfm values (the higher the better).. check out fans from vantec, zalman, coolermaster, spirecooler and thermaltake... i don't know much brands.. you may also want to try a fan controller (there are cheap ones around) so that you can control the speed therefore the noise hope it was helpful
