Ultra 6 Fan speed

I think evan is saying that the CPU temperature isn't used to throttle fan speeds unless it is > 50C I don't think its useful to display incorrect temperatures. Instead I would say "CPU temperature: ok" when the temperature reading is < 50

Erm the thermal readings are not incorrect, they are not the most accurate true, but on other atom chipsets (i have observed) its usually within a few degrees. Sure it's not accurate enough for thermal protection, but it is enough to know whether your cpu is running at near 30 or near 40. If I for instance observe a sudden increase in temperature it might mean the unit needs to be cleaned, or some other event that needs checking out. It's a useful tool, and I think it's a bad idea to delete information, sure the 50C threshold read should be there as well, but as an addition not instead of the thermal readings.

But my original problem were the fan speeds so lets get back to that, if CPU temperature is not used to control fan speeds what is? Because it really is quite annoying that my RPM speeds has increased at least 100 without system or harddrive temperatures changing AND ambient temperature dropping. Something must control that fan :)

edit: if the Readynas does not have a thermal temperature meter like other chipsets then disregard the above (i assume that it has both thermal diode and the DTS thing)
