Me? I've been comparing CoreTemp to the temps in HWMonitor and AMD Overdrive (both of which agree with each other). The display the Core temps and TMPIN0, TMPIN1 & TMPIN2 temps. I'm assuming (well, hoping) that TMPIN1 is the CPU temp.
The TMPIN1 temps are usually 12-15*C higher than the 'Core' temps.

From my own experiments, I found CoreTemp whithout any offset to read exactly the same as AMD Overdrive, right throughout the idle/load range. So yes they're definitely reading from the same sensor and interpretting the data the same. Trouble is, if CoreTemp and AOD are to be believed, my CPU max loads out at about 30C, LOL!

Surely that would be the core temps though, not TMPIN1 temps?
Which is why people add the offests as I don't think it's the core temps you need to monitor.

your right.

CoreTemp and AMD Overdrive reads the same fake reading under the core temp readings.

you shouldn't be monitoring the core temp reading.

tmpin0 or tmpin1 reading is the true CPU temp reading....

Yes the core temps. I think these relate to the actual CPU temperature but just need an offset to be interpretted properly. I don't know what TMPIN0/1/2 are reading TBH. They seem to vary from mobo to mobo and chip to chip. On mine, TMPIN0 reads higher than TMPIN1, which is about 10C lower than the core temps.

try EVEREST Ultimate Edition, it may label it as cpu temp

^ Also I notice that the core temp readings react very quickly when the CPU load changes but the TMPIN0 figure tends to drift up and down much more slowly. This suggests that TMPIN0 is reading a mobo heatsink or socket sensor and that the "core readings" are in fact more reflective of the CPU temperature. TMPIN1 and 2 figures do not appear to change regardless of CPU load.

pswfps · 13 Nov 2010 at 22:10

@gareth170 - the TMPIN0 is labelled "CPU" in both HWMonitor and Everest Ult, I just don't feel confident that they are reading what you think they are.

pswfps · 13 Nov 2010 at 22:11

Anyway, when it come to OCing, if it doesn't fall over then it aint too hot!

My 1055T has an 9-11deg offset between core temp and TMPIN1 which I believe is the CPU socket temp (gigabyte board). This is the one that reacts quickly to exiting prime. I have today put the computer into a Lian Li V1000 plus II case which has terrific airflow and I have reasonable cable management.
My idle temps at stock speed are core16C TMPIN1 26C, prime 50 minutes temps are core 30C, TMPIN1 41C the room temperature was about 20C.
I am using a thermalright ultra 120 extreme with an apache fan and a 120mm front inlet and a 120mm exhaust at rear. All fans peak at abour 1000rpm.

gareth170 · 13 Nov 2010 at 22:22

well this is mine.

temin1 reacts more quickly on mine. also i'm going on what amd told me. not to monitor the core temp reading, only monitor the cpu temp.

GoogalyMoogaly · 13 Nov 2010 at 22:22

Guess it must vary from motherboard to motherboard a bit. Like gareth170 I'm using a Gigabyte motherboard. All three values (TMPIN0, TMPIN1 and TMPIN2) all seem to change with CPU load, TMPIN1 seems most directly related as it reacts quickest in both directions.

@gareth170 - I don't suppose you know what each of the TMPIN0, TMPIN1 and TMPIN2 monitor on Gigabyte boards? (Assuming it'll be standard across the Gigabyte AM3 range?)

Thanks.

the 7 and 8 series are the same temp layout.

TMPIN0 = motherboard temp, TMPIN1 = cpu temp and TMPIN2 = motherboard NB chipset or the case temp.

it's your choice on what reading u want to believe.

but i know 100% tmpin1 is the true cpu temp reading on gigabyte board..

also i'm just going by what amd told me..

yeah thats right, tmpin1 = cpu temp

Hagar · 13 Nov 2010 at 22:47

I have done a lot of testing with and without OC. I also am 100% confident that TMPIN1 is the CPU or CPU socket temperature and that if you keep this within the permitted CPU temperature, in my case 62C you will be OK.

andy,

andy,

I've got the 95W version of the 1055T which I think has a max of 72C. not sure if that means it should run cooler or just has a higher maximum.

Does TMPIN1 react as fast as the "Core Temperature" readings though?

pswfps · 13 Nov 2010 at 23:37

Dear Gareth,

Correct, as long as you are within the voltage and temperature guidelines you are ok. The temperature that should be monitored is the overall CPU temperature, not the core temp.

Best regards,
Jesse

AMD Global Customer Care

Gareth,
You'd expect them to say that because the PhenomII does not have core temp sensors.
Did they offer any advice on how to actually measure the CPU temperature? Consider that their own AOD software returns the same figures as the HDMonitor "Core Temps" so again this adds weight to these being the correct base figure to use. The TMPIN0/1/2 figures are more than likely just socket/chipset temperatures on the motherboard.

Martini1991 · 13 Nov 2010 at 23:38

Don't listen to us.
We don't care.
You monitor what YOU want to.

The "core temp" is wrong. Deal with it.
