The I-Tee case I talked about elsewhere this week moves the power supply to the bottom though. Now that you mention it, that’s probably the most important thing about that case.

Oh wait, that’s a soviet submarine power plant design. I suppose they didn’t know what happens when sodium hits water…

I still don’t understand why power supplies are placed at the top of the tower, with the CPU heat sink typically right below it. This is the reverse of spot cooling – it seems that it is spot heating. There’s so much room in a case, one wonders why they did that. Planned obsolescence?

Somewhere, a hardware manufacturer is cackling hysterically…

I got a nice 750 volt shock off a piece of gear when I was in the navy. I shorted a rheostat to the side of a CRT. Zap! It put a very real fear of electricity in me.

And different models of switchers vary so much internally that IMPO this project absolutely should be left to the professionals, who are prepared to do the amount of checking required to ascertain whether or not a given heatsink is correctly insulated from high voltages: and for that matter whether or not it’s even worthwhile to do. Sometimes, as Dave F. discovered shockingly ;), switcher designers will cut corners on little things like insulating heatsinks electrically.

Besides, if someone’s thinking about water-cooling a power supply because it runs “too hot”, then it probably shouldn’t even be in the case.

Switching power supplies means that you are not only working with high currents, you are working with high frequencies as well. Not a good combination.

Anyway, the person who wrote the article must be really bored 🙂
