New AMD FX-8350 - Temperature question

I just installed an 8350 with no issues, but when I checked HWMonitor for temps, I got this:

There's quite a bit of disparity between the "CPU" temp and core temps. I've always heard that the core temps are more accurate, but I live in South Texas, and it's hard to believe I'm getting temps in the mid-20s.

Is there an issue I don't know about regarding FX chip temp sensors, or do these suckers just run really cool? I upgraded from an 1100t...

Core Temp is only showing the CPU temp, not the individual cores...

Does it not do this for certain CPUs?

This is got to be one of the most wildly guessed at readings I have ever seen. The single CPU temp is going to be the only one you want to pay attention to. If you google "CPUID CPU vs Core Temp" you will get as many guesses with no solid answers anywhere I could find. The most realistic thing I found was on an AnAnand Tech forum stating that the correct values are only attainable on a very few Intel CPU's. My best guess would be that it is a delta of differential between two specific but, unfortunately unknown values. If anyone can actually point us to a specific answer as to the Core temps relative value it would be most appreciated. I am going to keep looking, I will post again if I find a solid answer! But as a rule, the individual core temps are not the true value as some people with standard water cooling have actually attained 0C! Not possible. So stick with the higher CPU temp and ignore the individual core temps until someone tells us what it actually represents!
 


Simple, the higher value displayed in cpuid is the CPU Case temp while the core temp value is the average of the cpu's internal sensors. The value to look at is the internal one taken from core temp so long as the cpu case temp does not get out of hand.
 


Yes it displays different processors information in different formats. For you it's only displaying one internal sensor.

+1. AMD cpu's have one temp sensor for the cores and that is reflected against all core read temperature read-outs irrespective of the software you are using. The cpu temp you see in HW monitor is the cpu socket temp that your mother board is picking from a temperature sensor in your mobo's cpu socket.

That temp is usually higher as the socket is not air vented like the cpu header is by the heatsink fan. Add to that the fact that AMD temp sensors seem to have a negative offset (sometimes reporting core temps lower than ambient temps with stock heat sinks....I mean what in the world is that??) at least my room mate's 8120 does that.

So the gist of it all is that your system is actually behaving normally.
