Thanks very much, Copper. What kind of ambient temperatures do you have? Is the rig sensitive to hot weather? The key, clearly, is having an open space so you get natural convection to carry away the heat. Does undervolting also affect the kinds of Northbridge temps you get? Presumably this won't be...

First it's good to see Copper's posting, and I hope that somewhere on this site there are pictures of his fanless solutions -- last time I looked the pictures were down. I agree with Wim that it's worth looking hard at the SD11G5. But I want to dissent on a couple of things. First, swapping the fan ...

SpeedFan's temperature readings should let you compare the effects of different cooling strategies, rather than relying on touch. Record temperature figures for a whole usage cycle -- from a cold start through several hours of use. I bet half the HD's heat loss is through the metal top, so as you no...

Any system can be made less noisy up to a point (and even stock Zens aren't that quiet!), but as far as I understand it, the key noise-reducing innovation the Zen has that other shuttles don't is the external powerbrick.

The combination of hype and amateurishness on Sonica's site doesn't inspire confidence. Despite all that computing power they apparently lack a spell-checker ("proclame," "challange," "equiped"), and the writing is obscure. What exactly is their innovation -- a better fan controller?
