Whenever BOINC seems to run for 20 mins the BIOS alarm goes off and Speedfan says that the temp is about 75 degrees C. Is there a way I can lighten the load for my processor? My processer is a AMD AthlonXP 2000+ with a Cooler Master fan and big heatsink rated for a athonxp 2200+. I dont leave the PC on for too mutch after what I saw on one of Toms Hardware Guide movies I got of the web. The athlon and the board got melted! The thermal diode got destroyed and the system shut down immedietly |

the movie you saw on tomshardware was showing what happens if you remove the heatsink while the pc is running,, are you planing on doing that? if not, then why worrie? if your sure you installd the heatsink correctly this shouldnt be an issue,, as to the overheat itself check your heatsink fan, check the cables to it, check to make sure that "big" heatsink is mountied correctly,, did you use a good quolity thermal grease? or did you use a "pad" ? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "Pain dosen't hurt, when it's all you have ever felt" |

If you PCU heatsink/fan are installeedd properly (as per Paul), it might just be you need to add a case fan or possibly your cable layout inside the box is interfering with air flow (or both). Used to be one could just throw the basic pieces together and all would be well. However, CPUs generate so much heat these days that internal case air flow has become a very serious issue. Anymore, I tend to install two case fans, one to draw air in, another to draw it out. The cpu lies roughly on the air path between them. Luck -- Trevor |

I'll try that 2 fan idea but not clicking that answered question button till later! Thanks |

The cooling demands of the processor under constant load gets pretty high. This almost dictates that you cannot use the flat ribbon cables for drive connections because of the way they interfere with airflow. The other thing to be aware of is that you can put too many fans in a case and cause a disturbance of the airflow which results in hotspots. Think inflow from low on the front to outflow high in the rear. Tom |

What is the ambient temperature? What is the CPU temperature when the system is idle? What is the fans speed when at idle & when the alarm goes off (is it meant to vary with temperature)? I have an XP2600+ with the stock cooler running at 3,400 RPM & no covers on the case. 28°c ambient, CPU is around 40°c while crunching Seti. It goes up to as high as 52°c; or so when the ambient gets around the 40°c mark. Try the finger test. Touch the heatsink lightly when the system says the CPU is just under it's alarm temperature. If it's only warm then that indicates that the heatsink isn't fitted correctly- it should be too hot to touch. Or it means everythiong is actually OK & the BIOS is just giving the wrong temperature & an update is in order. Grant Darwin NT |

Besides the CPU temperature, what about the motherboard and case temps? If they're normal and don't change much when the CPU starts overheating, thats a sign the CPU heatsink/cooler wasn't installed properly or is too small for it. If they go up as the CPU temp goes up, thats a sign there isn't enough fresh air getting into the case to cool things down. |

I built my own 1900+ Athlon which is in a mini tower case. (midi, mini & full tower types.) This is one of the two I run SETI on, so you can see the specs in my profile. The Athlon64 is also my work. At the bottom front of the case I have two 80mm fans side by side sucking air into the case over the HDDs (2 of them. One 80Gb, the other 10Gb.) I have an exit port on the side with another 80mm fan blasting air out. At the back along with two more exhaust fans, (both 80mm) one below the other, I have installed a dual fan PSU. The PSU sucks air past a heatsink and fan rated for an Athlon 3000+ (same socket design) through the PSU and into the outside world. My average CPU temperature at full load (running SETI and CPDN 24/7) gets about as high as 53C on rare ocassions. Usually between 47C and 50C. If need be I just crank up the two exhaust fans on the rear of the chassis for a while to cool it down a tad. If you have a 2000+ and stock cooler (stock coolers for 2200s I think were the same part), I can quite believe it could get that high. If you can, I would suggest the move I made... Slap a 3000+ cooling solution on it. I made this decision after a really hot summer sitting there baking in the flat, I suddenly noticed my temps were skyrocketing. This move to the 3k+ heatsink just about saved my CPU. |

Just a off topic question: Can a athlon 64 work in the same socket without any ajustments on a ABIT VA-10/VA-11? |

> Just a off topic question: Can a athlon 64 work in the same socket without any > ajustments on a ABIT VA-10/VA-11? VA-10 appears to be Socket A (and KM400 at that) with a 333MHz CPU limit. Being socket A means there is no way it will support an Athlon64 of any type. It appears they will support Semprons upto & including 3000+ (VA-10 BIOS ver 17, VA-20 BIOS ver 10). Unfortunately though they will be severely limited by the KM400 chipset (think 3 legged dog, and those 3 aren't as strong as they used to be). Grant Darwin NT |

As regards to the Athlon64... There are two flavours... One 939 pin and the other 940 or 941 or something like that. FX53 and later are 939 whereas the original FX51 design is 940. Why the extra pin is anyone's guess. Back to the last post... The other temps are the 80Gb HDD and the mobo. These both read circa 30C. |
