But I am not AMD and I can't be 100% sure, this is just my opinion.
Next rev will have 49C\35W removed.

Thanks for clarifying this coolest ...I'm looking forward to the revision.

Hey man:
For some reason the forums where this is posted to download are down.
Can you mirror somewhere?
If the file is small, I can provide a mirror as well on my school web-space.

The server went down tonight because of a bad update, it is now back up :)
Sorry for the inconvenience

At stock, CoreTemp shows 10C higher on idle and temp than Speedfan (which seems right to me). Speedfan: 26/36 CoreTemp: 36/46

But when overclocked, CoreTemp shows 10C higher on idle and 20C higher on load :eek: than Speedfan. That really doesn't look right to me. Speedfan: 30/40 CoreTemp: 40/60

Help?

Speedfan doesn't show temp of each core.
That's a wrong way to compare.

Point taken, but I'm not really interested in comparing the values as I am comparing the temp increase.

If both cores are really increasing 20C, shouldn't speedfan which reads the temp sensor on the board show an increase of greater than 10C? My temp probe also only shows an increase of about 10C.

I've already popped off the IHS and replaced it after changing the thermal compound with arctic silver, so my temps should be better than what CoreTemp gives me. At least, I'd like to hope so :D

EDIT: The hotter core has an increase of 20C on load while the cooler core is more like 25C according to CoreTemp.
Also, I'm not knocking the program one bit. I'm just trying to figure out which one is right before my rig has a meltdown :)

this program show higher temp then other software-why?

this program shows idle temp that is 11 degress more then the temp that the MB software shows
and i understend that the core temp shuald be higher then but the is the 11 C diferent is OK?

i have TT BT

In my Experience Speedfan reads 10 degree's low on Idle and almost 20 degree's low at full load.

And if you think about it, it makes perfect sense that this reads higher than any other program as it is reading the Temperature from the Actual cores and not some sensor on the outside.

That's the kinda info I'm looking for. Thanks!

The sensor is on the outside but it is reading the output from the thermal diode inside the processor. AMD says in their white papers that the thermal diode can read as much as 14C low and that's assuming that the offset is properly applied and there is no error in the onboard sensor.

am i missing something... my 165 is naked and if i apply more pressure to diff areas on the block the two cores tempos dont change so its not a contact issue...
core 1 reading = 28C (on water this is seems good)
core 2 reading = 38c (seems a lil high)

Yes. Read through this thread. Temps such as yours are not because of faulty IHS or HS contact on DC processors. It seems to be a problem with the calibration of one of the thermal sensors.

everybody says speedfan reads lower temps than "core temp" except me ...

Hmm.. who knows. You do have watercooling though, right?

yes, external radiator o.O

Actually I also had it read lower than speedfan when i was running it on an amd 64 3000+ Idle was lower than speedfan. It was about 32 in the core temp checker while it was about 35 in speedfan.

It was the other way around on my opty 165 tho

Maybe the reason why I can't OC any more is because of the temps. Here I thought I was at 45*C when actually using this app I see I'm reaching 50*C. According to the app my TCasemax is 55*C so this all makes sense now. Guess I'm gonna adjust the RPM on my fan on my CNPS9500, I have it set really low right now (I don't like noise).

Hmm, so this means when my fan was speeding up to full @ 47*C when the room was really warm I was actually near that 55*C TCaseMax temp? Think I should get a new cooler.... or remove the IHS.... Hmm...

I love this programme. However, is there any chance of making the task bar icon when you minimize it show the CPU temperature, as opposed to having to hover over the icon? I reckon something like ATI Tool's temperature display would be awesome.

As you can see from the attached screenshot, Core Temp reports the exact same temperature as the "CPU Diode" value in Everest Ultimate Edition. Are both programs reading the same sensor or is this just a coincidence?

cool program. do we have a sticky of all these good programs? if not, we should

Both programs are reading the same sensor. It's mislabeled in Everest. The label "CPU" is actually the diode.

I kind of thought so, as that value jumps around (and skyrockets under load) alot like the CPU Diode readout did on my old Asus NF2 board. The good news, for me at least, is that I have a lot more overclocking headroom than I though I had since the "CPU" readout on Everest is always 4-5 degrees hotter than the "Diode" readout under heavy load.

BTW, MBM agrees with Everest as far as what it reports as a CPU socket temp. Is is possible that MBM is confusing socket and diode temps as well?

The bios and programs like MBM use the sensor on the motherboard to read the value of the thermal diode. CoreTemp uses the thermal sensor inside the processor for temperature readings. This sensor is used to shut down the processor in case the high temp threshold is exceeded. Until CoreTemp, and now Everest and NextSensor, no program used this sensor for temperature reporting.
