I have an A7N8X-X with an AMD 2500 barton boxed and I reach 30°C wth the MB
and 53°C with thew CPU. Is it OK? How much are the max temp?
Thanks
Fabio
 
FWIW my XP2000 on a A7V333 hovers at 55C on the cpu and 27C with the
case. So I would guess your temps are looking fine.

I have seen mine go upto 64C in the heat of summer, but thats a rare
occurance.

Fabio,
I'm thinking of buying that board, how do you like it and where did you get
it.
thanks,
George

It's ok if u do have a lot of heat in your room!

I do have between 48 and 51 with your same CPU overclocked at 2000 185@185.

Mainboard is A7N8X-E.
 
That is toooo much, unless u do live in the inferno!!! :-)))

Really? What should I expect? I have a Zalman 6000Cu heatsink and MBM
reports the diode as 64C after a 100% CPU task and the room temp is
25C....

Ignore that, the temps are fine, unless you're a hardcore cooling
maniac. :) The latest Athlon XP (Barton) are supposed to function in
temps up to 85°C, and the older ones up to 90°C.

If you get 64°C in summer, you're cool. ;)
 
It works fine but I am not an "expert" of motherboards and overclocking. I
bought it in Italy.

Totally don't, and I'm not a hardware cooling maniac, I do simply use AMD
fan in a good case on a safe room on an smart overclocked CPU! :-)

If Harry get so high temperature, it means he do have some BASIC cooling
problems, like CPU cooler with dust, not well fixed, and/or his case have
bad design, there is no hair flow inside it, and so on.

This do not mean it's good to run the CPU at 64. U can have more system
instability, u can risk components fail and finally u can be sure your cpu
last a lot less compared to a well cooled cpu.

The case has 2 80mm exhaust fans at the rear. Their is one 120mm fan
at the front blowing into the case. The PSU has 2 fans that push the
air out of the case too.

The CPU has a Zalman Cu6000 heatsink with Artic Silver 5. The HSF was
cleaned with Iso Alcohol and a very thin layer of AS5 applied.

In a room with a temp of 25C the case temp stays at around 27C. The
CPU diode reports 55C at idle. Under load the CPU will rise to a max.
of 60C. On a hot day (room temp 27C) the temp. reaches 64C

Tell me what more I can do to reduce the temp.? And I dont want water
cooling or jet engine fans either......

Harry
 
I confirm. Unless the roomtemp is 45 °C you shouldn't reach 64 °C on the CPU
die diode.

As a rule of thumb, with a good cooling (and/or an open case if needed), the
__ difference __ between the ambiance and the die temp shouldn't exceed 20
°C.

A CPU temp without giving the room temp is useless. Except versus the temp
ratings (ie. 85°C) for the safe operating area.

The greater the difference, the better. OTOH, cycling the die over a great
amplitude isn't good as well. It induces fatigue inside the die soldering or
gluing.

Review your PC internal cooling. I guess in your case, the chipset reaches
more than 60 °C on the heatsink. Place a thermocouple and see ! This means
probably around +75°C on its die. Moreover if the airflow inside the case
isn't correct, the CPU is warmed by the chipset, warming the chipset in
turn. Endless loop leading to a very long stabilization when the CPU use
decrease from 100% to a fraction.

Open a hole close to the CPU in the rear panel, suck warm air from this hole
and inject fresh air in front of the chipset/CPU through the side panel.
It's magic ! You'll win 20°C on the CPU die. A 120 mm fan with a reduces
speed will be both efficient and silent but more expensive than a 80 mm fan.
That's the price to pay for quietness!.

Have fun.
 
In addition, are you sure you aren't blowing the hot air coming from the
hard disks onto the chipset and the CPU ?
I optimized the cooling in my computer using a large sheet of cardboard with
a fan mounted on it. I moved this sheet in front of the disks, the CPU, the
chipset and the middle of the board. The best place is just in front of both
of CPU & chipset. The CPU temp decreased of 10°C, the chipset temp fell down
of 22 °C !

Now, the side panel is open, the 120 mm fan is operational (dunno the speed
but low because silent).
CPU is 46 / 49 °C (idle / full load), room temp is +27°C, Socket is +37°C,
MoBo is +32 °C, IDE disk is +27°C, SCSI disk is +38°C (placed on the top of
the case where the cooling isn't optimized yet).

These temp are reported by MBM5 and +/- 2 to 3 °C accurate.
Don't forget the acuracy of the measurements when you say the CPU is 64 °C
it could be 69 °C !!!!! depending on the means you're using.

The PSU fan should such air from the top of the processor, blowing it
outside. Obviously you have hot spots inside the case.

Check the correct direction of the air flow, like Aldo Suggest.

Also double check volgage (is your CPU maybe overvolted?), have u applyed
a thin layer of CPU paste between your cooler and the cpu? Are u sure
there is no space between the die of the CPU and your cooler?

If u do have a original AMD fan, please try it. THis things are cheap but
they are engineered by AMD especially for AMD processors and in my
experience they work great.

I never ever bought another vendor fan becouse I always find AMD is the
best!

Then, I do subscribe everything Aldo said.

U have to check the problem if u don't want a not stable and soon died
system :-((((((

The CPU was OEM so I dont have an AMD Heatsink. But I did install a
Volcano 11 and the temps were similar.

I will open the case and see if the temps are reduced to sensible
levels. If not, then I guess I might have a Heatsink problem.

Last night the room temp was 23C and the CPU was at 54C idle and 59C
under load.

That is what I do at the moment. At the bottom front of the case I
have a 120mm fan blowing air into the case. This air passes over the
Hard disks. Then I have 2 80mm fans at the back of the case sucking
air out of the case. The side panel does blow air into the case, may
be I should reverse the fan here.

The PSU sucks air out of the case too.

Yes the front 120mm fan blows across the HDDs.

Much as I would love to reduce the temperatures, I would like to avoid
the cardboard solution. Their must be a simpler way. How do all these
PC makers do it?

I will try the side panel off my PC tonight and see what the temps
are.

The PSU does suck the air out of the case so that one thing that OK I
guess.
