Has anyone out there purchased one of the Fujitsu-Siemens motherboards with motherboard-based fan regulation? You can read about them here
. (Click on "premium features".)
How about the Asus motherboards with "QFan" technology? Has anyone used one of them
It would be great to see a comparison of these two technologies/motherboard types from the silent computing perspective. The F-S boards seem really respected for their stability and to be seriously committed to acoustic management. The Asus boards seem generally more feature-rich (possibly allowing underclocking or undervolting, or memory tweaks), but QFan is a new thing for them, whereas F-S has apparently been doing its thing for a long while. The Asus boards seem a little less expensive and a lot easier to find, whereas the F-S boards are apparently available from only a few vendors (in the US, just Silicon Acoustics, Sharka Corp., and Ambient Computing, as far as I know).
So does anyone actually have any have any of these motherboards? Any comments on whether the fan-control technology is worthwhile or not? I kind of have the impression that while these features might be great for casual users who just want their computer a bit quieter, they don't really seem to be necessary for someone who could just use a bunch of 5V Panasonics instead.
