Overheating Issue
I have a box I built for handling long 3D renders and I am having major
overheating issues. The box is identical to my primary machine in every aspect because I need my renders to look exactly like they do when I create the proofs on my computer. Fans, CPU, motherboard, video card, memory, etc.. all exactly the same. Even the same case. When Speedfan says the CPU temp is 75c, I can touch the heatsink without burning my finger... In fact, it doesn't feel hot at all. I've come to the conclusion that the CPU heat sensor must be defective on this system. But I don't know if the sensor is on the motherboard or on the CPU. I have a Gigabyte GA-MA78G-DS3H rev 1.0 motherboard with the latest BIOS update (F8) and a Athlon 64 X2 4800+ Brisbane CPU. I don't have any spares to swap out and test, unfortunately. Any ideas? |

Any ideas? 1) Speed fan not configured properly giving wrong temps. 2) Contact bad between cooler and cpu. 3) Inadequate case cooling.

Any ideas? 1) Speed fan not configured properly giving wrong temps. EasyTune5Pro reports the same temps as Speedfan. 2) Contact bad between cooler and cpu. A friend suggest this and I removed the heatsink, cleaned up the arctic silver and re-did it with no improvement. 3) Inadequate case cooling. It's all relative. I'm using the same fans and configuration as my main machine. Speedfan reports the same RPM range as my main computer for all 3 case fans. The two computers sit next to each other and the case temp is the same for both. Is it not possible that a CPU heat sensor could be bad? If it is possible, do you know if the sensor is on the MB or the CPU? I believe it is on chip nowadays Pokeyman |

Um, why don't you just swap the CPU's between the two boxes and see if the
problem follows the CPU or stays on the current machine? "DaveN" wrote in message . .. I have a box I built for handling long 3D renders and I am having major overheating issues.

If the cooler is not hot to the touch, and you're sure the cooler is making good contact, then I wouldn't worry too much about it. But, I'd double check the cooler mounting. It's not hard to have it cocked where it's not really making good contact. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org My Tivo Experience http://wesnewell.no-ip.com/tivo.htm Tivo HD/S3 compared http://wesnewell.no-ip.com/mythtivo.htm AMD cpu help http://wesnewell.no-ip.com/cpu.php |

It's not hard to have it cocked where it's not really making good contact. I'd also compare the two coolers to the touch. If the one showing the higher cpu temp feels cooler than the other one it's almost certainly a poor contact between the cooler and the cpu but if they both feel about the same then it's likely to be the sensor in the cpu. Have you tried Everest Ultimate at http://www.lavalys.com/products.php?lang=en, it shows a temperature for each core and the overall temperature of the cpu on my AMD 64 X2 4000+. It is available as a 30 day trial. -- Regards - Rodney Pont The from address exists but is mostly dumped, please send any emails to the address below e-mail ngpsm4 (at) infohitsystems (dot) ltd (dot) uk |

Always good to hear that you resolved the issue.

Thanks, I thought of that yesterday afternoon and did just that. The problem followed the CPU. So it looks like I have a bad chip. I went to my local computer store and they had the Phenom II 940's on sale, so I bought two of those and upgraded both my systems. Everything is running great now. I'm going through the RMA process on the bad processor and I sold the other on Craig's List. |
