case cooling

[Bin_Lagered]

im in the process of completely revamping my case cooling as im getting a new case to replace my old poxy one. atm my cooling consists of 1x80mm out (back), 2x60mm in (front), pci blower out and volcano hsf

im thinking about doing a bit of ducting also, probly to the side panel.

Is ducting cool air in or hot air out the best method?

i have heard hot air out is good as it improves your case temps but this will require changing fan directions i imagine.

also when using a duct is it better to have positive or negative air pressure inside the case?

It is better to extract the heat out of the case, as the component beside CPU (NB/Mosfet) will have longer life as it don't have to feel the hot air coming from the CPU...
