Normal Temp for AMD Phenom II

[gibsonfirebird12]

Hello,

I can't seem to find this anywhere in my manual or on the AMD website.

What is the normal idle and medium load temp for an AMD Phenom II 945?

Thanks,
Tim

Well, I just underclocked my CPU to 2.8GHZ, and with the stock cooler, Idle is 30C, Med Load is 42C-45C, High load is about 50C-55C. My temps drop by 8C-15C with my Arctic Cooling Freezer 7 Pro Rev.2

On stock cooling I would expect 45C depending on room temp.

Mine with aftermarket cooling idles at 35C.

Load I would expect 55-60C on stock.

Aftermarket for me is 45-50C.

These aren't usually supplied in the manuals etc since they vary depending on the case, location and airflow. Any temp below 70-75 is good. The 945 you have if it is the lower wattage version, get some aftermarket cooling and you'll get very nice temps out of it and you'll be able to run the fan slower, thus quieter.

AMD specifications for the 3 flavors of the PhII 945


Edit: I fergit .... Here is a C2:

I'm pretty handy with volt tweakin' --- might be tough to match that

Thanks for the reply...I just recently changed my thermal compound, and I've never done it before...my cpu is idling at 42c. do you think this is a good idle temp?

It is most important to compare your temps with your Vcore -- these things are relative.

As you experiment with your tweaking keep a small spreadsheet and note at idle and load:

1) Clock Speed
2) Vcore
3) Temps

With that experimenting you will find your sweet spot, beyond where additional clock speed requires an 'outlier' bump in volts, and which results in a corresponding leap in temperatures that does not follow in an incremental fashion.

You will have hit the volt wall where the CPU struggles to gain more clock speed without giving it inordinate increases in voltage (that result in quickly rising temps).

Did you do the 'small rice grain' of TIM ?

Sorry, I am slightly new to all this. I have a Vcore reading on my computer, and an RPM reading (clock speed)...the rest of what you're talking about kind of stumps me, not sure what, "small rice grain" of TIM is...More info would be helpful, thanks. Sorry for the n00b questions.

Sorry, I really don't understand what you're trying to say...

I looked up small rice grain of TIM (i didn't know what TIM stood for ), I did not use this method. I read online that if you have a square, you should just spread it out.

Basically, I replaced my mobo and had to reapply TIM. I wiped the old one clean with isopropyl alcohol, and spread a paper thin layer on it. I noticed my idle speed went up about 10 c.

So today, I went back and put more paste on, also by spreading it. It went back down the 10 that it went up.

If my temp is ok now, do you think the paste is okay?

 

[Wisecracker]

I'm not a big fan of the 'spread it thin' method ... beneath the heat shield the actual cpu die looks something like this ...

from Tom's

Most heat shields are somewhat concave to flat, and the AMD latching mechanism on the HSF supplies good pressure to level the TIM in the area of the CPU die.

As long as your temps are within the specs listed above you are okay --- but poor installation of the TIM will increase temps and reduce over-clocking headroom.

Okay, thank you. I am idling around 30 c. If I see my temps go up more than that over time, I will reinstall with grain of rice.

If that happens, then there is something new wrong, since TIM does not magically disappear or change that significantly.

If that happens, look into dust buildup.
