Wrong temperature readings
Hi,
I have a 2500+ Barton at stock settings on a Gigabyte GA 7VT880 Motherboard. The problem is, I don't know if my CPU is running too hot because I don't know what the exact load temperature is. With Prime 95 the highest temperature reported by EasyTune4 (whose temperatures are the same of the BIOS) is 55°C. MBM5 and other utilities say that the highest temperature with Prime 95 is 60°C. It's very important for me to know which temperature to trust because I'd like to overclock my Processor but I will do it only if I know the right tmperatures. I have the feeling that the temperatures reported by the utilities like MBM5 are right, and they are high because the Gigabyte Boards report temperatures higer than the real value by about 10 °C. But what about the Bios?? Is the Bios reading wrong temps? Is it possible that the Bios reads the temperature from the socket sensor and MBM5 directly from the on DIE sensor? The motivation for this could be the fact that the MBM5 temps rise very quickly when Prime95 is started, and sink quickly when it's stopped. At the contrary, the temps read by EasyTune4 sink much slower, perhaps because it reads the temperature of the air trapped under the CPU which logically takes more time to cool down. What do you think about it? Thanks in advance for your answers |

When in doubt, go for the highest .....

Temperature readings on motherboards are only good for relative comparisons in your system. Did moving a particular fan increase or decrease temperatures? As fas as determining whether your CPU is "too hot" or not, they're next to useless with (1st-hand experienced) variations of 20 deg C between boards. Generally, if it's stable under Prime95, then it's not too hot unless you're running an insane voltage. You can, with a great deal of effort, calibrate the sensor. But it's usually not worth it. In general, anything under 70 deg C is fine as far as damaging-the-CPU goes. Much over 70 and I'd start to worry, given that the board is quite possibly reading 10 or 15 deg C too low, and the maximum temperature for desktop AMD CPUs is 85 deg C. Of course, the lower the better (though if someone gets a lower temperature than you, it doesn't really mean anything).
