Inside Out


Project Passive

In order to have more cold air around the voltage regulators, and components in general, I decided to turn the insides out. This way the heatsinks would be against each other, and they would create a "convection tunnel" in the middle. I also built a different kind of attachment for the PSU. It is bit fugly, but at least the PCB isn´t bent anymore.

Something had to be done about the wires. I covered the wire for the graphics card with a showerhose, and made voltage rails out of thick, anodised aluminum rods. Here you can also see the third heatpipe for the graphics card. It is continued with a fourth heatpipe to the other side, in the PSU heatsink.

Here you can see the slim slot-in DVD drive, as well as the HDD in its silencing box. I knew from the start that boxing in the PSU was a bad idea. But since it was mounted with the PCB outwards, I had no other way of making it safe. I knew it would drastically shorten the lifetime of the PSU, since other components like capasitors don´t much like heat.

At the time I was in a hurry to get the case ready for Assembly '07, so I didn´t much care if the PSU wouldn't last long. But alas, it lasted even less than I thought. I used the computer fine for a while, but when I moved it to a better location for taking pictures in a better lighting, the PSU broke. A little capacitor flew out with a bright flash and a loud bang. It might have been the heat, or maybe the bending of the PCB. But the most probable reason is a short circuit caused by a speck of aluminum, from all the drilling and sawing.

Even though I knew Antec power supplies to be generally bad, I bought one anyway. Well, I was in a hurry, and a friend happenened to have a NeoHe 430W for sale, so I bought it to replace the Fortron. The Antec was physically better suited for the job, as it had large heatsinks, and the heatpipes could be made to fit in between the fins. Finally I covered the PSU with a meshplate to give it proper ventilation. I´m sorry that I don´t have more pictures about this, but as I said, I was in a hurry.
