CPU temperature

Hi,

I started to monitor my system temperature after some ?trouble?.

A few days ago my system was shutting down all of a sudden, after the first
time I realized that there was a strange smell hanging around.
Just an half hour later I rebooted without any problem so I thought this was
just an occasional situation.
The day after the same situation occur and I noticed that my case was quite
warm on the top near the power unit.
Finally after the 3rd time the power unit stopped working completely.

The power unit was only 230W and is about 5y old so I simply replaced it by
a 350W.

Now I noticed that the cpu temperature is 58°C and and 42°C for the system;
I'm using the motherboard facturer's monitoring tool.
The cpu is a AMD 1800+ with a silent cooler and was working without any
problems for about 8 months

Are these temperatures normal or what could be the reason for it?

Thanks in advance for any suggestions,

The temps are a bit on the high-side, but considering that you're
using a "silent" cooler that's to be expected. If the cooler is
actually described by the manufacturer as "silent" or "quiet", then
this is where the problem lies... a good silent cooler isn't one
described as such, which typically means it just includes a low-RPM
fan, but rather a decent silent cooler is one known to be very high
performance (with a high RPM fan) but which instead has a lower RPM
fan on it. In this way you get the far larger weight and surface area
of metal that allows a low-RPM fan to achieve the most cooling per db
noise.

Since you system temp, at 42C, is also a bit on the high-side compared
to average, you might consider increasing chassis airflow, adding
another fan or two. A decrease in system temp should also decrease
the CPU temp, though if your motherboard uses an onboard, in-socket
temp sensor instead of reading the temp from the CPU's on-die diode
then minor variations may not be as evendent in the temp readings, but
are occuring nonetheless. A fan in the bottom front of the case will
often change the system temp reading more than one (or another) in the
top rear, but this is mearly due to the placement of the sensor itself
rather than actual air temp. If you don't already have an >= 80mm
exhaust fan behind the CPU, on the rear case wall, that should be the
first fan to add as per AMD guidelines.

If the system is stable (which it likey is, from a heat perspective,
unless the CPU is highly overclocked) you could instead ignore those
temp readings and be content, but make sure other components like the
video card and hard drive(s), CDRW, etc, are remaining cool enough.

Hi Dave,

Thanks for your reply.

I had never looked into temperatures before and since my system started
shutting down spontaneously I was not sure where that came from.
Now that I had to replace the power unit that problem was solved but for
sure I kept on monitoring the temperatures.
Apparantly this motherboard is not well calibrated because the temperature
at startup is already 28°C for the system and 56°C for the cpu.
I also installed a bigger fan which only results in more noise, the
temperatures are the same - a half hour after booting: 39°/74°C

The system is running stable and performing well so maybe nothing to worry
about.

Yes it is mounted properly with special paste, according to the bios the fan
is running at 3750Rpm.
I can touch and hold the heatsink very well, let's say it's no more then
50°?
