AMD CPU temps

[GuessWho]

I have a AMD 3700+ San Diego core processor installed on a MSI 7025 mobo.
I'm using the stock HS/Fan and pad. I used the auto overclock feature of the
MSI overclock utility to get the CPU up to ~2500 MHz. Above this the system
reboots.

According to the MSI utility the core temp runs between 48 C - 50 C and the
case is at 37 C during idle or low use activities. When running at default
values the CPU is 46 - 48 C and the case is 36 C. Under load ( encoding HDTV
to DIVX ) for several hours at the default CPU setting the CPU gets up to
around 53 C. I'm not a gamer; so this is the most demand put on this
machine.

I know the temps are within the AMD specs but they seem high given my wife's
AMD 3000+ Venice core on a MSI 7125 mobo idles at 37 C with default CPU
settings. Is it worth the trouble to reseat the HS/Fan on my San Diego core
machine? I realize I will have to clean off the AMD heat pad and use a
different thermal compound. I did use Antec's thermal compound when I
assembled the Venice core machine.

TIA,

Wayne

I would not do that. But I would buy a few high-volume, reliable fans
for the case (double-check airflow direction) and also make sure the
pwr. supply has extra capacity and a good fan.

I have same CPU, OCd to 2.64. I found that CPU was reaching 64C when at
full load, so fitted AC Freezer 64Pro, which is quieter and cooler.Download
SpeedFan. On my MSI 7125 , what the utility program reports as system temp,
apperas to be southbridge temp. If you do have a case temp of 36C, you need
an extra case fan to improve the airflow. Check cables are tidy and not
obstructing the airflow.

One and 1/2 years ago I put an Athlon 2700 XP together using an MSI board. I
found the idle temp to be 52 degrees C. This to me seemed abnormally high
since I'd previously put an AMD 2500 XP together earlier with it running at
36 degrees C and read on this newsroup of others who reported comparable
temps. So I ordered a Thermaltake cpu something for $30 and it brought the
temp down maybe 5 degrees. Whoopie. Since then I've been using the system
with no difficulties and have concluded, or perhaps just rationalized that
the MSI mb simply has an inaccurate temp sensor.

Isn't the operating range maximum somewhere around 85 or 90°C?

Your 36°C is significantly cooler than the air temperature in my city
on a hot summer day.

No you don't. It wouldn't hurt, but 36C is not hot.

1. Different CPUs radiate different amounts of heat. Your temps are
fine, find something bigger to worry about.
2. Not all motherboard sensors are accurate. If you can't find something
bigger to worry about, buy a pair of temperature sensors and put one in
your wifes computer and one in yours. See that your temps are still fine.

All those temps are considerably lower than the temps reported by my
ASUS motherboard and AMD Athlon XP 2000+, with three case fans and a
nice PSU with good fans in a large roomy Antec case.

Ari

Mike,

I do have SpeedFan but I just use the MSI utility. The values reported by
the MSI utility are the same as those reported by SpeedFan and my BIOS.

This box came with 2 80mm rear case fans and a side panel fan already
installed. It is a big box with relatively little in it and I've made the
cabling as tidy as possible, although the box itself is in a rather confined
area.

I've been running the machine for several hours with the side panel off and
temps dropped a degree or two.

I've never been able to get to the Help section for SpeedFan by usingF1. Do
you have any idea what may be wrong?
