990FXA-UD3 Rev4: HWM and Speedfan Sensors?

[KevinWalter]

As the title says, I'm running a GA-990FXA-UD3 Revision 4. I currently have it paired up with an FX 6300. Quite happy with the performance so far.

However, I'm not sure how to discern temperature readings in my monitoring programs. There seem to be 3 shared readings between the two programs that are specifically monitoring motherboard sensors. Along with, of course, GPU and the CPU itself. The CPU is listed as "Core" in Speedfan, and it matches the reading listed under my processor in HWMonitor.

The other three readings are as follows:

HWM:                  SpeedFan:
System                Temp1       - 32C
CPU                     Temp2       - 39C
TMPIN2                Temp3       - 20C

The labels seems a little odd. I'm not sure why the motherboard would be displaying a CPU temp of 39C when the reading for the processor itself is around 20C at idle. Unless it's normal for what I'm assuming is the socket to be roughly 20C hotter than the chip's own sensor?

Clarification would be appreciated. Also, are there any temperature limits for these components that I may wish to avoid?

Thanks.

Yes, the core temperature is on average 10C lower than the socket depending on how well ventilated the case is.. and the core temperature reading is only accurate under load - idle temp reading is rubbish.

the core sensors on the fx series tend to be giving out too low values when youre not under load, or lets say, when youre below ~40C. thats absolutely normal and nothing to worry about. my fx8350 had a reading of sometimes like 09C core temp in idle.. but under load with higher temperatures the reading will be way more accurate. better that way, then the other way around, isnt it?

This is absolutely not normal and should have been fixed years ago. AMD too dumb to get that fixed? how embarrassing!
