On the recent Athlons the max temp has been a range from 55 to something in the 60s/70s.

The "see what temp it fails at" method won't work because the temp you end up finding will be pretty high (probably in the 90s), and those temps will cause damage in the long term.

If the things run off 5v or 12v it should be straightforward. Those are the two voltages provided in the standard connector used for drives and stuff. Just to connect them backwards, or else you'll toast something.

Doing it in the BIOS does save power, about 2w for an Intel. I doubt disabling it in Windows would make as big of a difference.

Some BIOS's have an option called CKE Power Down, which may be enabled to begin with (my laptop does it automatically). It puts the ram into standby when it's not being used, and that reduces power to a fraction of a watt.

You have to remember that there's not much you can do with P3 SpeedStep to begin with, you only have to hardcoded settings to choose from. There's an Intel utility for SpeedStep. I got it from the laptop maker's site, not sure if there's another place to d/l it. http://www.intel.com/support/processo...

If you don't mind used you can find a laptop (with or without LCD depending on how old) for around 100-150. Considering the 9w idle I got out of my old P3-based E500, it should be interesting. I would recommend the bottom half of a Dell D600, those are very common and have undervoltable Pentium Ms.

The 5200+ would be the fastest, because of the cache, it being 90nm (the 65nm chips are slightly slower even with the same cache), and likelihood of higher overclock. The Brisbanes would use less power and thus be cooler. It is not a huge difference though. The difference between each model of Brisb...

Well if you must buy new, a desktop would be cheaper.

Aside from performance that's the only advantage I can think of, power wise. Since this is Silent PC Review, a desktop has several advantages on that front (lots of space for bigger heatsinks and noise dampening),

As I recall it was the only way to get old GPUs to work on lower voltage and get lower power consumption.
Underclocking (and some limited undervolting) is controllable via software on most new GPUs.

The desktop Core 2's also step down when power is not needed.

Basically there is less of a need for mobile processors because of the above.

Did you also consider AMD processors? They also step down, and there is a cheaper motherboard selection.
