Wow, My AMD 2400 CPU runs over 60 degrees at almost all times.  The
AMD 

chip

can safely run into 90+ degrees according to their website.

I installed extra case fans and my case temps are usually 30 - 35
degrees cooler then my CPU temps (both monitored 24/7 by motherboard
monitor). 

I'd love to run my CPU cooler, but beggers can't be choosers I guess,
I 

just

assumed I had a low end heatsink.

In article <JE_bc.181877$_w.1839554@attbi_s53>, Tony Payne says...

The cpu is frequently overheating, very often at the end of 1 WU
and 

the

start of another.  I have checked the cpu and fan mounting, have
the 

right

amount of thermal compound etc etc, but it's really frustrating
to 

find

your

system powering itself off every couple of hours.  I also don't
want 

to

fry

the processor or motherboard.

Change your fan.
Even some extremely cheap fans will do the job properly.
I have a XP1700+ overclocked to XP2200+ rating (1800mhz) and it
runs 

around

45�C under full load (seti).

Even during hot summer days it never goes over 55�C.
The fan is GlacialTech Igloo 2400PRO which was around $10 year ago,
and 

is

one of their lower end fans.

So look into it before your CPU dies.

Thanks everyone for your help.
I'm now running SpeedFan (www.speedfan.com) which helps to monitor the
speed of the fan(s) and shows the temperatures.
Even without Seti running, my CPU is at 23C, Motherboard 52C, AUX 34C,
but the killer is Temp2 at 77C.
I'm not sure what Temp2 is, it's reported from the L90 chip on the
Soyo motherboard, and this is what's causing the system to shut down. 
With Seti running the temp goes from 70's up to 90+ which is steaming
hot.  For sure I need to find out what this is and cool it down -
unless it's a faulty sensor!
One question I do have is that I have the covers off the case and have
had for some time.  I would have thought that having the covers off
would allow the system to cool better, but does this also prevent the
air flow from the fans from being channelled?  In this case having the
covers off is bad.  I have a good Ultra CPU fan, plus a new 550watt
power supply with 2 fans.  The previous power supply was only 300watt
but the system still overheated - this one doesn't seem to make much
difference. Any thoughts?

 Those temperatures are almost certainly wrong.  23C for a CPU?  That's 
about room temperature.  I expect about the only way you'd achieve CPU 
temperatures like that would be with a water-cooled system.  Looking at the 
temp's you posted, my guess is that the motherboard (not AUX) is 34C and 
the CPU (not the mb) is 52C.  Those would be fairly normal temp's.  If you 
haven't already, you should do some research on which sensors listed in 
SpeedFan apply to which actual sensors on your motherboard.  I've never 
used SpeedFan, but I assume it gives you a number of choices.  For example, 
I'm using Motherboard Monitor (MBM) 5 and it lists 3 sensors with two 
"types" for each sensor.  My motherboard only has two sensors.  Trying to 
use the non-existent sensor in MBM 5 gives me anomalous readings.  
Likewise, trying to use the wrong "type" of sensor gives me weird readings.  
If you weren't having shut down problems, I would assume that the reading 
that's varying from the 70's to the 90's was from trying to use either a 
non-existent sensor or the wrong "type".  But if you are having shut down 
problems, I suppose you should make sure that reading isn't legitimate.

 Like I said, do some (more?) research on which sensor options in SpeedFan 
actually apply to which sensors on your mb.  And if you've already done 
that and are sure the settings in SpeedFan are correct, then maybe you've 
got some kind of hardware problem and are getting bad sensor readings.  I 
suppose you could also try MBM 5 and see if it gives you the same results.

 As for opening the case, I guess YMMV, but my system definitely runs 
cooler when I remove the side panel.  As I recall, the mb was at least 
several degrees C cooler, but the CPU didn't drop as much, which seemed to 
make sense.
