Ok what I should have said that it was reading 36c as soon as I turned it
on, but quickly rose to 52c in a matter of minutes and then sat there..

If this is the bios readings then I'd say you have a problem with the
cooler, bios, or cpu. If this is a program reading after the OS has loaded
then it may not be configured correctly

100% loaded it still shows 75c +.

Now this has to be an OS reading. And I'm also pretty sure the CPU would
shut itself down if it actually were 75C. When I lost the fan on my 3000+
the cpu shut itself down somewhere just above 61C. By the elapsed time
from seeing 61C, I'd guess it shut down somewhere around 65C. Yeah, I
watched it climb from about 40C to shutdown just to see if it would work.
It did.:-) ACtually, it was climbing so slowly I thought I could get the
fan replace before it would shut down. Didn't see any sense in manually
shutting it down just to change a dead fan.:-)

system is not over clocked and cool and quiet is enabled...

You have to do more than just enable CnQ in the bios. It requires control
software. You can download it from AMD for windows.

And 75C is going to be hot enough so you won't leave your finger there
long.:-)

Exactly. If the heatsink's too hot to touch comfortably then there's
definitely something wrong with the cooling.

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.

Actually, if the HS is hot then you know the HS is seated properly and you
just need a better fan or cooler. If it's cold and the cpu is hot then
it's a good chance the HS is not seated on the cpu properly.

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.

Ok check this out and read what it says under max temp

Well dosn't cool and quiet work by lowering the vcore voltage?????

Not going to re-enable it............ and system is quite stable.......

Sure. Lowering voltage will always lower temps.


hence the way that cool and quiet works....

And your basing this on??????

Take the side off of the case and see what happens. It sounds like you
have a problem with your case fans, taking the side of the case off will
confirm it. With the side off you should see a much lower rise in
temperature.

Agree about adjustments, but for all you know his room temp could be 30C
, it's not easy to keep a CPU cool in a hot room!

I think he stated earlier that room temp was 26C.

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.

Well I have now got Water cooling. Installed a Thermaltake Bigwater and now
have alot cooler temps.

System is now sitting at 55c (down from over 70c) fully loaded. This is with
the 12cm fan turned right down (1200RPM) and it is also alot quieter that it
was with the stock cooler on. With the fan at full speed (2400RPM) the temp
drops to 52c. The chipset temp also dropped to 37c (down from 46c when
loaded..)

When at Idle The temp drops to around 32c on both the CPU and the Chipset.

So overall the $145 water cooling system is working better than the stock
cooling fan. So this cooling system must be on of the exceptions to the "
most commercial water coolers under $200 won't work much better than air."

How hot is your room? My 4400+ CPU never goes over 40C with an ordinary
air cooling, it idles at 30C. Either you have your system in a steambath
or there is something wrong with your temperature sensors.
