Greetings, I just got my new Processor today, and it seems to be running too hot.
I did not overclock it or change any voltages, the only thing I modified is changing the thermal grease after I noticed the bad temps, which did not help.

Everst is reporting the following:

CPU 44 °C (111 °F)
1. CPU / 1. Core 50 °C (122 °F)
1. CPU / 2. Core 50 °C (122 °F)
1. CPU / 3. Core 50 °C (122 °F)
1. CPU / 4. Core 50 °C (122 °F)


This is obviously bad. I tried letting the system cool down, but it jumped up rather fast.

Another strange thing I noticed is differing sensor values.
When I last started the PC, I went into the BIOS and looked up the CPU temp: 39°C
Right after Windows started it was at 50°C, measured with Everest, AMD Overdrive and Speedfan.

Right now it's idling at 50 - 55 °C.

Is it the thermal grease? I know they take some time to unfold their full power, but this seems to be just to much.

When I raise the CPU load to about 90%, the temp jumps to 59 °C, but it was never under 48 °C idle for longer than a second.

Edit: Using the tool of my mainboard I can fetch the BIOS sensor from within Windows now.. this one's reporting 43 - 45 at idle, and Overdrive keeps bumping on 50.. which one can I trust?

Edit2: Naww, looks like the BIOS is just measuring the case temp, not the cores..

Hello,
at what speed is your CPU-Fan running?

I think, that BIOS reads CPU-tems and Overdrive takes the Core-Temps.

That dose't look right, Cores at 50 and the over all cpu temp is only 44.. My core temp never gets higher the CPU temp. What mobo are you using? and are you using the stock heatsink/fan?

Your mobo has two thermol sensors. One is behide the cpu and this one that gives your cpu temp and the other will give your mother board or your case temp.
The BIOS reads the one behide the cpu.

First, how did you apply your thermal paste, and what paste are you using now? I was using the stock cooler on my phenom II when I first got it and it was running 43C idle with no overclock, so you should be much lower than that. As far as what temps to trust, I've been told by several here that Everest, HW Monitor, or AMD Overdrive are the ones to trust, and they all show similar numbers for me.

Check your BIOS and see if Cool N' Quiet is enabled, and disable it if it is. Turn off anything that might be throttling your cooler fan back. Also, Having higher core temps than the overall CPU temp is normal, mine does the same. Good luck!

I'm using the Gigabyte GA-MA770-DS3 Mainboard, and the stock cooler and heatsink.
The fan runs at around 3000 RPM

Cool N' Quiet was enabled, I disabled it, no change in temperatures.

I applied the thermal paste by covering a small circle in the middle and let the pressure of the heatsink spread it across the processor.
The paste used is an Arctic Cooling MX-1.

I applied it yesterday, but it at least has to help in some way..

60+ is close to dead-end, 44 is bad. I've seen people getting 28 °C in idle...
I' giving the grease some time to fire up, and if it's not good within 5 days, I'll consult my local computer store on cooling solutions :S

Here's a few thing to check.
Frist, check to see if your getting enough air flow though your case. Do this by opening the side of your case and see if theres any change.

Second, check your cpu voltage (v-core)

Temperature remains stable at 49 - 53 when case is opened.
AMD Overdrive is reporting me 1.325 volt.

This means that you probably have good case airflow, so keep it closed.
I didn't know that MX-1 was still available, is this possibly an old tube you had lying around?
The better thermal compounds are MX-2 and Arctic Silver 5.
I suggest getting a tube of either, apply it according to their instructions, and re-seat your HSF.
Your voltage is well within range, the 940 can go up to 1.50v.

I agree with Nemesis
Your getting good air flow and your voltage looks good. So it either old thermol paste or your not appling it right or both.

I also agree you should get a new tube. I like arctic silver myself but MX-2 will do the trick too. Just make sure to realy clean off all the old stuff first. this will help make sure you get good contact.

If this still dose't help then the only thing I can think of is getting a aftermarket heatsink.

The thermal paste was new, I purchased it with the processor. MX-1 is rare, but it had good reviews, I'll try another one anyways, thanks!

can somebody help me.
i'm a newbie here
a week ago i bought a phenom II x4 940 BE, i used corsair vx550watt PSU, two hard drive, using vga on board ati 3200.
my board is ECS AMD780GMA-Ultra black series.

when i check the core temp (with everest, AMD Overdrive, and speed fan) they all show average 70'C, the lowest i ever saw is around 62'C. when at high load it around 84'C

is it dangerous??

i use a stock heatsink+fan. fan rotates at 2800rpm

any idea/suggesstion of what should i do?

Hi

I have the same mother GA-MA770-DS4 with the Phenom II 940 processor and experience the same temps of over 50deg idle. Using the stock thermal paste provided.

I also opened my case and it dropped to about 49deg.

I'm considering the cooling solution from Noctua. Don't want a nice noisy CPU cooler.

Cheers

I have the Noctua cooler and still get temps of up to 50 at idle and almost 60 at semi-load. I'm pretty sure the core temp sensors in a batch of these Phenom IIs are dodgy, given then number of threads about strange temps (some as high as 80), but unless AMD makes a statement about it, we'll never know...

Im having exactly the same reading 50-53 degrees idle (not overclocked).
Thats because you have set the power options in control panel to a High performance plan, and thats normal, remember high performance means more voltage per core along with more speed clock, try to change it to a power save mode and You'll see a temp drop as well as clock speed, however if you want to run your processor at maximum capability, needs to be under high performance plan.
So if you want to low the temps and keep high performance, just get another fan different than the stock and do not overclock unless u do it balanced

I had the same problem. Here is how I fixed it. If you are using Vista or now Win 7, make sure that your power options are set to "balanced" and not high performance---the latter of which which keeps the processor running at maximum. Also, if you have an Asus board you probably have the "Cool and Quiet" option in the bios. Enable that and download the Cool and Quiet utility from Asus and run that. My CPU was idling at 120-140F, but now is idling at 111F. Good luck!

I have very similar problems according to cpuid at idle cpu@44c and cores 1-4 43c and stock fan @ 4299 rpm when running web surf around 50c but running an online game of 8ball club billiards it will climb to 66c with fan @ 6490 rpm and not OC'd just stock @ 3.0 GHz . I removed stock thermal grease pad (it was running about 50c@idle) and used artic silver 5@ 3/4 bb size that dropped it 6 degrees. So I will definitely get me a better cpu cooler
