CPU temp onA7N8X

I have the Asus mobo with an AMD Barton 2500. Ive noticed that the CPU temp
is in the range of 104 to 117 deg. F (39 to 42 deg. C).
I've got 3 chassis fans in the box exhausting the air but the temp seems to
stay in that range no matter what I do. Is this the working range of this
CPU, I know with a liquid cooler I could get that temp down lower, but is it
worth it?
Thanks

Its pointless posting this without saying that your ambient temperature is.

I have a very similar configuration: AMD Barton 2600, A7N8X-X,
Thermaltake Volcano 10 CPU cooler (all copper) and 3 chassis fans.

The CPU temperature is ranging from 40 C (idle) to 51 C (100% usage).
The external temperature was about 25 C. My feeling is that these
temperatures look OK, so your temperatures should be fine as well.

By the way, two questions for the ASUS experts:

1) The ASUS probe shows the CPU temperature. Does anyone know if this
temperature is from the Athlon internal diode or is it from a mobo
sensor under the CPU?

2) As many others already reported in this newsgroups, I'm
experiencing a higher-than-normal VCore (BIOS setting is 1.65V, but
I'm reading 1.71V). So, I'm wondering whether the VCore is really high
or perhaps the voltage sensor is not precise as it should be?

amd cpu are made with a internal diode temp.

A got the same mobo and cpu running at default.
the temperature are the same at idle and full load.

but for the vcore mines is running at 1,65v +/-
my bios version is 1007

maybe you got the 1004 one and is the problem.

And i would love to know if anyone of you got this strange thing going
on.

It about the fan (noise/speed) that is reducing and slowing down when
my cpu is at full load. What would cause this happening?

I've wondered about that too, as all my PCs do that. At full load,
the +12V supply is heavily loaded, and the voltage drops slightly.
PC power supplies are not that tightly regulated, as many of the
supply designs share a common primary drive for all the secondary side
outputs. This means when a single output on the supply is heavily
loaded, the primary side drives harder, and all outputs try to
increase in voltage at the same time. This kind of design saves
on manufacturing cost and saves space inside the power supply, but
it doesn't give the tightest regulation.

For the absolute best "fan performance", there is a controller
board made in Japan, that actually monitors the tachometer signal
from the fan, and adjusts the voltage to it so that a constant
fan speed is maintained. Using a product like that, you'll
never hear the fan change speed. It is too bad that this design
concept it not readily available at retail stores.

An example of a "deluxe chip" to control fan speed is here. This
chip would allow someone to make a design like that Japanese board:

My guess is that the voltage sensor is inaccurate. It is difficult to
get a precise A/D conversion for such a low cost. I suspect there is
enough variability in the components used to account for the
differences.

Gregory,
I guess I should have stated that I sit at this machine in my underware for
hours at a time.
70 deg. F
 
Same board here but with a 2800+ Barton. I should note that I cool the CPU
with a Swiftech MCX462+/Sunon SHO 84cfm fan, a bit noisy for some perhaps
but in a closed, well ventilated case and over time have gotten quite used
to it. I live a good size townhouse but no basement per se so my rig is in
my living room in a corner, and the room temp doesn't get much above 70F so
the mobo temp hovers around approx.10-18C depending on ambient or a window
occasionally being open. I would suggest to you that the most efficient way
to air cool a case is to have the fan(s), the more the merrier here, sucking
air in the front and then exhausting it out in the back above the PS in
most cases. My CPU temps fall between 30-40C, idle to full load which is
near what you have so you're in great shape. A high end heatsink/fan combo
might garner a few more degrees but it's trivial here in your case. I too am
looking into liquid cooling, only for achieving a more quieter solution
since I'm centered in the family gathering area now. What I'm finding out
though regarding liquid cooling is, at least for me, unless an exotic method
is used, e.g. Asetek VapoChill (http://www.asetek.com/) or equivalent,
you'll run somewhat cooler but a whole lot quieter but I'm not sure I want
to invest a few hundred bones on just a 'quieter' solution so is the dilemma
I'm in at the moment. IMHO with CPUs and video as fast as they are becoming
nowadays, overclocking is becoming more moot by the day, my .02

Regards,

JR
