Temp of Dual core system

I have recently built the following computer :

AMD dual core 64 bit 4200+
ASUS 8AN-SLI mobo
2 gig Hynix DDR ram
256Meg 6600GT Pcie vid card
250Gig SATA-II Maxtor HD (16meg buffer)
Thermaltake 450 W power supply

this sits in a Full tower case with a fan sucking cool air in at the front.
and a second fan at the back blowing warm air out of the case.

Now when at idle the CPU temp sits around 52c and the mobo chipset around
39c

When fully loaded, with both cores reporting 100% loading (running 2 seti
programs at once) the CPU temp shoots right up to around 79c

Are these typical temps for the dual core? or is there a problem.

The CPU is using the standard AMD heat sink and fan that came with the CPU.
and was installed using the stock thermal pad that came with it.


Has anyone had any experiance with water cooling.. Have had a look at a
Thermaltake unit and may just invest in one.

Those temperatures are way to high. I have a 4400+, with both cores
running at 100% the highest I've seen it go it 40C. Are you sure that your
case fans aren't fighting each other? As a quick check unplug one fan and
see what happens to your temperatures.

You must have a big problem. I have a brand new x2 3800+ dual core and using
cool and quiet I am running at 20C right now. I have never got this core to
get above 37C. It replaced a clawhammer 3500+ that would idle at 29C and go
up to 51C at full load. This dual core runs so cool I question wether I even
need cool and quiet running.

Have you loaded the processor driver and enabled Cool n' Quiet, both under
the BIOS and under windows?

Sounds like you have not enabled Cool n' Quiet, and the processor is running
at full voltage and frequency all the time.

My dual core, with the standard CPU cooler, rarely goes above 40 degrees. I
have only two 120mm fans, one intake and one output. I am running 4 HDD and
two opticals.

There's a problem, but probably with your temp sensors, as the cpu would
have shut itself down long before reaching 79C I think. Either that are
you don't have the cpu cooler on correct.

The CPU is using the standard AMD heat sink and fan that came with the
CPU. and was installed using the stock thermal pad that came with it.

Plenty good enough.

most commercial water coolers under $200 won't work much better than air.
Forget it. You don't need water cooling. Just find an fix the problem. If
the cpu cooler is mounted correctly, I'd suggest a bios update. Some
bioses reported wrong temps. Or if you're using a program to read the
temps, it could be configured for the wrong sensors.

Done . got the lattest bios

Bios is reporting the same as ASUS probe..

did a little test...

Turned the computer off and let is sit for 3 hours to cool down...

On start up I went into bios and checked the temps, and the bios showed that
the cpu temp was sitting at 36c. the ambient temp was 23c, so I think the
bios is reading the temp wrong..

Maybe your fan is on backwards.

Hi, you said at idle your case temperature is 39C thats way too high, try
cooling the case more, just make sure you have more exhaust fans than intake
or equal CPM in and out. Never more intake CFM than exhaust. Higher case
temps or amibient temps push your cpu temp that much higher.

May have solved the problem. happened to find the AMD spec page for the
processor and it said that the max temp was 49-71deg c.



It also gave details of all the operating specs.. including vcore. Which it
listed as being between 1.3v and 1.35v.



Checked mine and it was running at between 1.37v and 1.4v. Had a look in the
bios setting and it was set to auto for the voltage settings.



Changed that to manual and set the voltage for 1.3v. After rebooting had a
look and was surprised to see the same value being reported for vcore
(1.37v).



Decided to check the bios again and found that it was still set the way I
had. But this time I disabled the cool and quiet function. Did the old
reboot and what do you know.. Vcore now reporting as 1.34v and the temp had
dropped..



Went back into bios and set the vcore lower to 1.25v and rebooted..



Vcore now showing 1.29v and the temp has come down again.



Ran the seti program and have had it running now for 2 hours and the max
temp is now 64degc (well inside AMD's temp range)



So it looks like it was a combination of the cool and quiet and the AUTO
setting in the BIOS causing the problem..



Still may look at a water cooler to see If I can get the temp down a little
more.

Max temp would be a single number, not a range. I think it's called T-case
temp. Ahh, so now you use Tcontrol 70C max for dual core.

You should have left that alone.

You're flirting with instability, not to mention CnQ didn't function on my
old hammer core when I changed vcore.

Vcore now showing 1.29v and the temp has come down again.

Sure. Lowering voltage will always lower temps.

Ran the seti program and have had it running now for 2 hours and the max
temp is now 64degc (well inside AMD's temp range)

No, I'd call well inside the range at about 50C or less.:-)

So it looks like it was a combination of the cool and quiet and the AUTO
setting in the BIOS causing the problem..

To be honest, you didn't fix the problem. you made adjustments to decrease
the temp. Under load that CPU shouldn't go over 50C.
