i saw the second motherboard fan, and i think also the infinity(or fatality, forgot what it was called) motherboard has it, but i ment a direct cpu exhaust, not a "close" to the cpu, one, thats why i was surprised , i know a bit related one, i was it in a btx case i think but that was a mod, which i have to admit is quite nice, basically someone used acrylic sheets to separate the cpu from the rest of the components, so only the intake to the cpu fan was abve the acrylic part, and the rest was ducted to the top exhaust fan, that thing looked weird, but i guess it did what it was ment to do, and the guy had a direct vent going from a bottom side fan towards his gpu card, and that air did get exhausted to the back(i think it was one of the 1900 series cards) so only bacically the other 2 (1 front, 1 side) fan did cool teh rest of components, and i guess the psu, so his temps were rather looking good on all components lol
actually i was thinking about making a small duct from my upper side fan to go directly to my cpu fan, but im not shoor if that wil bring the temps down by a lot (cost/benefit problem
) and i was thinking about ducting mu botom side fan to move the exterior air directly to the (or close to the ) intake of my gpu, that whould bring the temps down bu atleast couple of degrees, hopefully, ....has anyone done so maby?
