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.

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. |

[...] Just installed the latest version of core center, and my temp dropped immediately by about 8c, 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! -- Don Burnette "When you decide something is impossible to do, try to stay out of the way of the man that's doing it." |

"Ed" wrote in message ... 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? Chip |

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, 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. -- Abit KT7-Raid (KT133) Tbred B core CPU @2400MHz (24x100FSB) http://wesnewell.no-ip.com/cpu.htm |

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? Chip 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. -- Don Burnette "When you decide something is impossible to do, try to stay out of the way of the man that's doing it." |
