here is a teaser. i'll post some more pictures and maybe add some more info later
[update] the image is now hosted on my uni server. it should be quite reliable so if it is down you can go screaming in panic right away.
the processor is an amd xp 2000+ (1,6 GHz)
undervolted from 1,75v to 1,70v which didn't drop the temperature much (1 deg max). but since it's running stable i kept it that way
the duct is made out of cardboard
before the duct there was a 80mm fan over the alpha and a 120mm fan at the back of the case sucking air out
now the 120mm fan in the back is sucking air out through the duct over the alpha. the fan over the alpha is removed
the temps with duct are just 1-2 degs higher than before (without duct with fan over the alpha)
to make it short i removed one fan for the price of 1-2 degs higher temps and i think that it's worth it. although i barely hear the difference ^_^;
(hadrolepton's ego: "just shut up and post the pics! think about the fame and glory you'll get when posting this in spcr!!!") yeahh... *hadrolepton mumbling to himself* ... thank you ... thanks ... oh please that was not necessary ... award of excellence yeah ... *drool* ... ... ...
note: when i said i'll add some pics later i mean like couple of weeks later not days later so don't hold your breath
