Phenom II 955 temps

[pbmaster]

Just curious to see if mine are decent. Room temp is ~26*C, idle the CPU sits at 39 to 40*C and full 100% load under Prime 95 is sits at 49*C. "Gaming load" it sits at 45*C. Stock CPU settings. Using the Cooler Master V8 with Arctic Silver Ceramique. I was using AS5 but I was curious to see how well it spread, so I took a peek, saw it was good and replaced it with Ceramique just to see if it made a difference.

Are you reading the core temp or the CPU (socket) temp?

 

[pbmaster]

Sorry, should have mentioned that. I'm using Overdrive and Coretemp. Both report the same.

 

[WSP]

If you can add more pressure to the cpu,it might saves a couple degrees.

And also,a very thin layer of TIM is all the cpu needs.me myself using a synthetic motor oil

btw,that temps is ok though.just a little bit on the hotzone,considering your cooler

 

[legends84]

your temps is the nearly same as mine.

the temps is ok for me.. never hit 50c even load in gaming

 

[Wartz]

About the same as my 940 (if that helps), but I am at 3.6ghz.

 

[pbmaster]

I thought it was kind of warm too. I'm going to reapply today using good old AS5 instead of Ceramique. I hope I get it right this time, this thing is a pain to keep removing.
@WSP: Motor oil? That doesn't seem like a very good TIM at all..

 

[pantherx12]

Well anything liquid that dosnt evaporate will work nicely really : ] ( or corrode the metal and plastics)

believe me...I've went through many kinds of TIM. be it AS5, AS ceramique (still had 2), MX-1, MX-2, NT-H1, Chill Factor..etc and the best TIM is the motor oil

I'm using a synthetic one, Shell Advance VSX. just a drop of it is enough.

the basics of me using motor oil is:
* it sticks to the heat
* it doesn't conduct electrolit (mineral or synthetic oil)
* doesn't evaporate quickly (more boiling points than water i believe)
* very2 cheap (just dont using the used one, use a fresh one instead)
* easy to clean
* also act as a cooler beside hsf (motor oil is widely used to cool engine without water cooling)

try it, and you might surprise yourself

the downside? It cant be used in sub-zero conditions. get freeze instantly!

screen or it didnt happen^^ i wanna see temperatures!

here's the viewing pleasure ^_^

up and running crunching for 7 hours and still go on.....

how much better is it than mx-2?

I thought im one of the few who experimented heat transfer process
on my experiment too im using a blue marine grease, it beats any thermal paste on the market on my experiment, if you want sub-zero try lithium grease(white), its used to lubricate evaporator fans on a freezer

 

[WSP]

about 5-7°C cooler in my case. compare with AS ceramique, it is 3-5°C cooler

I also experimented using synthetic grease, but it gets sticks to the IHS, almost like glued to it. harder to remove hsf, and perform worse than motor oil (about 5-7°C hotter)

I never tried lithium grease, but I will soon if I got one and honestly I never seen one lol

what is hte lithium grease you mentioned in this link?

currently using AS Ceramique when doing sub-zero (DICE)

arctic ceramic ist 5 degrees hotter than ceramique ;-)

 

[pbmaster]

Fixed my temps. Remounted with some Cooler Master Thermal Fusion 400. The Ceramique had spread nicely, but there was barely any suction with it. Temps are sitting at 36*C idle and 47*C 100% load.

 

[largon]

Too bad these temps are pretty much meaningless as the one single temp sensor in Phenom II (Deneb/Heka) is quite useless as it is located in the coolest possible place on the die and is around 10ºC off anyways.

 

[pbmaster]

So you're saying right now, sitting here, my CPU is idling at 48*C? I find that hard to believe.

"However, at the same time we have some very good news for overclocking fans. The thermal sensors integrated directly into the CPU cores of the new Phenom II X4 965 processors have finally been calibrated correctly. It means that during work in nominal mode and during overclocking you can finally use not only the readings off the thermal diode beneath the CPU socket, but also the readings off the CPU itself, which are more precise and have considerably lower lag effect."
"....Unfortunately, it took AMD over 6 months to fix this issue, but we hope that we will now see correctly calibrated thermal diodes not only in the top Phenom II X4 processors, but also in other 45 nm CPUs." http://www.xbitlabs.com/articles/cpu/display/phenom-ii-x4-965_5.html

If my understanding is correct, the Phenom I had that problem. According to this the 45 nm CPUs should be fixed.

 

[largon]

Here's a little test I did back in march, soon after I got my P-II X3 720BE:

The probe bead was tucked inside Scythe Ninja baseplate, between the heatpipes. CoreTemp version 0.99.5.

 

[pbmaster]

BIOS up to date? I'm not trying to be a dick to you, but mine isn't like that. I just find it extremely hard to believe my CPU is sitting here at 46*C doing nothing but me typing. Coretemp .99.5 and Overdrive tell me it's at 36*C.

You actually misunderstood the quote, the Phenom II X4 965, the processor that just came out has fixed the issue. It wasn't done months ago when the CPU first came out. I know my x3 runs stupid low and the explanation given by largon gives insight as to why.

 

[pbmaster]

"not only in the top Phenom II X4 processors, but also in other 45 nm CPUs."

That's what I'm going off of. I still REALLY doubt my CPU has hit 70*C.

 

[largon]

pbmaster,
What are your idle clocks/vcore? Do you use Cool'n'Quiet or 3rd party apps that underclock/volt the CPU while idling?

About the xbitlabs quote; I wouldn't put much weight to their ramblings as they even refer to some silly "thermal diode beneath the CPU socket" while such things haven't existed since Socket-A.

 

[pbmaster]

No Cool and Quiet, no undervolting, no underclocking. Stock speed: 3.2 GHz. Stock volts: 1.35v. CPU cooler is the Cooler Master V8. Sitting right now at 36*C according to CoreTemp and AMD Overdrive.

 

[largon]

Admittedly 46ºC @ idle would seem less likely.
Could be sensors in early dies like mine (0851) were off and got fixed in later models...

PS. is that a typo in your system specs as it says "Phemon II"?
