I am trying to increase the amount of air to be taken into my desktop. i have 2 fans on the front of the case blowing air in, and 4 fans blowing air out (2 on top, 1 on the back, and the psu on the back) If i double stack 2 fans together with about an inch of a gap, will this fry my connectors? or should i buy another Hard Drive Fan Bay to blow air in?
if by double stack fans you mean put one on top of the other blowing the same direction then dont do it....it actually decreases airflow...one fan impedes the other....there is a reason you never see this in peoples rigs. even with an inch gap between the two I wouldnt do it...if you are looking to increase your airflow replace the current fans with higher cfm ones.
Do you have the option to add fans to the side panel? When buying fans you can look at the specifacations to see what the cfm and db arre to know what the fan is capable of. You can get higher cfm fans but you may also be adding more fan noise to the case as well so paying attention to the db's will help with not adding too much noaise.
