Default XP 3500 socket 939 high cpu temps?

I just completed upgrading to an Athlon 3500 90nm winchester core, with an
MSI Neo2 Platinum mb this past weekend.

I got the oem processor, along with a Thermalrite XP90 heatsink, with a 80mm
( i think) fan.
I used Arctic Silver 3.

My cpu temp as reported by corecenter, and in the bios, idles around 46-48C,
and gets into low 50's under load. System temp is 25C.
This is the first time in my many system upgrades that I have had a heat
problem. My Athlon XP 2800+, overclocked to 3200+, idled around 36c and
only got to app 42c under load. I have also noticed even at idle, the temp
can vary 3-5 degrees C very quickly, which I find unusual.

I am concerned about these temps. I am not overclocking the system yet,
running all at stock ( 11x200). My case cooling is good, I have it in a
Lian Li pc-75 full tower case, which came equipped with 2 cooling fans in
front, and two in back. At this time, I do not have Cool N Quite enabled.
My cpu fan is turning at 3800 rpm.

Any suggestions would be appreciated.

Thanks,

Core Center except for the latest version is not accurate. The lastest
version on the MSI website also will read high CPU temps but will give
a better reading after a warm reboot. If your system temp is 25 I would
suspect that your load CPU temp is in the high 30's or lower 40's. At
this time my temps are 35-39 with stock cooling with both Core Center
and MBM.

Thanks, I will try out the latest version. I booted up just now after
getting home, and it immediately showed 45C - I know that can't be right
from a cold boot up.

I tried installing MBM yesterday and kept getting an error message, I
figured maybe it did not work with this mb, will try again as I prefer it.

Thanks,

You were dead on!
Just installed the latest version of core center, and my temp dropped
immediately by about 8c, I also successfully installed MBM and it is
reporting about the same. High 30's at idle. I am sure load will be low
40's.

I was worried for nothing. I will also get a little better fan than this
cheapo I have on this great heatsink, and I am sure it will help as well.

Thanks!

This is why the absolute value given by motherboard temperature monitors are
useless. The reading you get depends much more on things like BIOS revision,
monitoring program, board variations, etc than actual CPU temperature.
*Relative* readings are useful (keep everything the same but change fans,
does it get hotter or colder?) but absolute readings don't mean much ("nyeh
nyeh my setup runs cooler than yours nyeh nyeh" - yeah, right). If it's
stable (Prime95) and not overvolted significantly, then it's not getting hot
enough to be damaged so there's nothing to worry about.

Of course, if you are doing serious overvolting and/or subzero cooling, then
things change, but if you're that serious about things then you a) know what
you're doing and b) know that there is an signficant chance that you will
damage/kill your CPU and are not worried by this.

I agree. I always overclock my systems, and had not started so yet on this
one due to the temps being reported. However, I will say, I must have not
had the heatsink mounted on good, or the arctic silver 3 not on properly, as
I was experiencing overheating when I first assembled. This is about the 5th
build for me, and first time I had this problem. I even changed to the
thermal paste provided with the XP90 Thermalrite, yuk - stuff was like glue,
bent some cpu pins when trying to remove the heatsink - the gluish effect
probably because of the heat.

Cleaned everything off, carefully applied a thin layer of arctic silver 3,
and carefully mounted and matched the XP90 to the cpu. Much better!

fwiw, I got the best temps by putting no more then about 3/4 of a BB's
worth of paste right in the center of the CPU, then put the heatsink on
and lock it down. The temps were higher when I spread the paste out over
the whole top of the CPU. (2 - MSI /Clawhammer systems)

Ed


How much higher, Ed?

I can see that you could get a thinner layer of AS if you use the "3/4 of a
bb" method. But how much difference did it make?

Check the temp readings in the BIOS to make sure that they agree with the
temperatures reported by MBM. If there is a disagreement I'd trust the
BIOS readings over the MBM ones.

You can't compare those as the bios puts a load on the cpu and should read
higher than an idle OS reading. There's about 6C difference in mine and I
can see it rise in the bios if I exit the os fast and go straight to bios
readings.

Well the one PC (3000+ clawhammer OC'd 200MHz) die temp dropped about
10C running Prime95 max heat test, the other PC (claw 3400+ no OCing)
dropped about 5C.

One CPU got ripped right out of the socket when I went to re-do the
paste (paste was spread over whole top), it's still working though. ;p

Ed



Funny you mention that. I first used the Arctic Silver3, and spread a layer
across the chip's surface. When my temps were going through the roof, I
cleaned it off and tried the paste. When that didn't work, I pulled my cpu
out of the socket as well - stuff was like glue. It bent some pins on my 939
processor, and had to carefully bend back to get the cpu to drop in the
socket again. Luckily, seems to be fine. I used a thin smooth layer across
the surface. I still think my temps could be better, I may try the bb trick
to see if that is better.
