there isnt a floor to how cold they should go
(at least til the point that the processor would crack but you wouldnt be able to reach that unless you have liquid nitrogen or something)
but too hot isnt good

I checked all over AMD's website but the documents they offer do not contain the complete thermal data for their chips. Intel, however does provides this data
here in this pdf. On pages 75-76, it describes the operating temperature range and in table 5-1, they state that the lower limit temperature is 5°C.
Cold temperatures are NOT good for electronic equipment. Most retail mobile devices (most notably cell phones, digital cameras, mp3 players) have a temperature range listed in their manual which the player should not exceed.
In addition, only under very controlled conditions will a certain material exhibit superconducting properties, but only specific condcutors will behave as such.
Too cold is bad, too hot is bad. ALSO, ignoring the lower-temperature limit from a real-time electronic effect sense, going above or below the operating temperatures will physically, not electronically, destroy the constituent components of device. In other words, you'll have fractures, open circuits, short circuits, etc. etc.
Sorry, I just gave a long presentation and am still in "educate" mode.
Owl, I'm unde the impression that Speedfan just reads data from the hardware itself. Your BIOS and Speedfan should give you the same readout since they are both interpreting the same sensor signals. I might be wrong about this thoigh, so don't hold it against me if I am. You would need to install a second thermal sensor in order to verify the true temperatures, but I don't think unembedded thermal sensors can yield very precise readings.
