Which temp is the right one?
Monitoring CPU temperature
Tuesday, October 23, 2007 by Bebi Bulma | Discussion: PC Hardware
I rebuild my machine recently and having reinstalled Speedfan it nicely labeled everything for me (had to label them myself last time). However, it's showing me two different sensors: CPU and Core. I'm not sure which one is actually the proper readout for my CPU temp, and when I was trying to research it I found someone that said: "A very important note. Never use CPU temp to see how hot your CPU is. Use Core temp."
There's a huge difference between the readings for the CPU and Core temperatures.
Any ideas as to which one I should be using? I tried opening a bunch of junk to see which one went up, and they both did.
AMD Athlon 64 X2 Dual Core 4800+ Socket AM2 Brisbane 2.51GHz
MSI K9A Platinum AM2 ATI CrossFire Radeon Xpress 3200 ATX AMD Motherboard

Err, well that won't help me much considering the desklet I use to monitor all this stuff requires speedfan. 
This is what coretemp shows me:
From the readme: "The latest 65nm BH-G1 and DH-G1 revisions give inaccurate readings." Can't seem to find which one mine is....I just know mine is a 65nm. [link]

Doesn't help much to have the wrong temps either...... 
Run that other app just to see what your temps really are so you know what you're looking for.

Just use the CPU temp. That mid to high 30 range is perfectly acceptable for a high end closed system.

So basically they're both displaying the wrong temps? Someone on the AMD forums mentioned that about the Brisbane core. 
And ROFL and not actually LOOKING at the screenshot to see the details of my CPU.
Been a long day (damn fires).

Not necessarily.....everything seems to be high, including your HD's, but they all fall into an acceptable range. As long as the CPU temp is rising and falling on load, then I think it's close enough. Once you get use to the temp fluctuations, you'll be able to see a problem should it arise.

Well it has been warm here lately, and this is about the average temp from the previous build as well.

I think your CPU temp. is the right one! 15C is not much so you will need a very good cooling to get it.

Excluding the HD's, none of those temps appear correct.
