I've changed my rig completely, again. This time, the PSU is ducted!
The original trick with the harddrive I did on the other thread
, turned out to be terrible (here's what it used to look like
). I hadn't noticed that the strings holding the harddrive were letting vibrations get to the case. The entire case was "humming"! Yikes. I figured out a better way using foam.
Temps: are looking good. M/B: 37°, HD: 33°. Bad part about the Zalman7000Alcu is that it's failry loud. I'm running it at ultra-low voltages, but that makes the cpu hot: between 55° at 5V and 65°/71° at 3V/2.5V (big difference in noise through subtle changes in fan speed). I've opted for 3V, 65° is safe enough for me & a sweet spot in noise/cooling. This is at 2GHZ/Athlon T-Bred 2400+, while folding, ambient room temp 22°.
Good news is that the PSU is getting fresh/cool air through the duct. The duct was fairly simple: Carefully measuring & cut out some cardboard. I made sure the cardboard is covering as much as it can, so that no hot air from the cpu can "go up" to the psu. The harder part was getting the cardboard in. Proud of this duct.
