I also mean in regard to the min/max settings... and a high-value of
+4°C for mainboard temperature doesn't seem to make much sense either.
Whatever, I'm positively surprised that it actually works - that I get a
read-out at all.

I'll give that a try (I'm not at my amd64 box at the moment), thanks.

He, I'm not that stupid to be running at static fan settings ;) I wrote
a small php script that scales from 100 at 30°C to 255 at 42°C or
something. It's not perfect, but it works and seems to be reliable - I
ran a full load test with some maple computations and it kept cpu
temperature at about 37-38 °C.

I know that it's usually not a good idea to write such a script on my
own when there are better solutions already available, but my
understanding from e.g. the fancontrol manpage was that it needs the fan
rpm readout - and that doesn't work (yet).
