The weird thing is I left my computer idling yesterday as well, and it peported temperatures as low as 17 celcius. Same results with coretemp. Any ideas as to what may be going on? I'm not sure if they're reporting the correct temperature anymore.
Using an x3 720 on a gigabyte mobo.
I'm not familiar with that processor, and tentatively assume it is an AMD CPU.
I can tell you matter-of-factly that the following sorts of peculiarities emerged as Intel released their Penryn (Wolfdale and Yorkfield) cores. Motherboard makers who had released mobos for the earlier Conroe processors did not keep up with a change in how temperature sensors are read under the Penryn models.
It took several months before BIOS revisions showed temperature readings more in line with what one would expect with the new cores.
Further, again in the Intel context, Wolfdale and Yorkfield processors were known to be defective or "stuck" for the core sensors. They wouldn't register accurate temperatures until the core temperatures had exceeded the "stuck" values. Intel also issued a disclaimer statement that "the sensors were not meant to measure idle temperature values" -- or measure them accurately.
For the volume of thoughts I'm posting here, it probably exceeds what I should offer to an AMD user ( . . . that IS the type of processor you're using, isn't it?)
Also,
mentalcrisis00 is absolutely correct about choice of thermal monitoring software. Those that seem to give the best results are:
HWMonitor
Everest Ultimate [appropriate revisions]
Coretemp
RealTemp
SpeedFan has been notorious for misleading or inaccurate readings -- at least for several of the newer CPUs. I don't see how SpeedFan's author -- Alfredo Comparetti -- would be any more diligent updating the software for AMD cores than for those by Intel.
