Im new to this forum, hope im welcome as well. 12 years ago I built my own aleph3 with the help of some real nice people at pass labs, now it is featured at pass diy, front page. You probably can't imagine how happy and proud I am right now. I know I messed up when I made it, I didn't know anything except I wanted something real nice, one of a kind. I thought the cooler you ran an electrical device the better. So I went overboard on the heatsinks. .07 deg. c. per w. Well, I had found out later that heat helps the devices, so I put variable resistors on the 24v dc fans and ran them as slow as possible, it was too cold. When I first made this I was going to make it dc powered, as the rail voltages lend themselves to that possibility. It was too expensive... But now, 12 years after I made it I want to go all out with what I have and can modify. I can, with the fans, safely dissapate 450w per side, I know the irf 244's cant take it, hey I'm willing to do what it takes to make the 30 wpc aleph3 dc turbo. I wanna build again. This time skys the limit, and suggestions?
