Another lm_sensors post, I know, but I haven't found anything specific to this combination yet, so maybe someone can offer advice. I set up lm_sensors and the output is shown below. This is during compiling, so I would have expected the core temperatures to be much higher, especially since it's in a warm cabinet in a room that's warmer than that to start with. Also, several of the voltages seem way off. +4 on VCore 2 would kill the processor, +6.85 on +5 I'm sure would damage stuff and +4 on -5 is completely out of whack.

I haven't had a chance to look at the bios readouts yet, as I'm at work now, but I'll compare them tonight. In the meantime, does anyone else have any insight into whether this should actually work or not or why I'm seeing such discrepancies? I would have assumed I should be using i2c_nforce, as it's a nVidia MCP61 board, but that didn't seem to get picked up by the sensors-detect, and these two did. I do have support in the kernel for i2c_nforce and it did probe it, but determined that it wasn't sensor readouts that it found.

You are seeing discrepancies because although you have a known sensor chip on your motherboard different manufacturers use the sensors in different ways and also use different scales for the values then the default sensors.conf file. For me I have never had a system where all of default values made sense in the default sensors.conf.


I generally trust the k8temp numbers because they come from the cpu itself but those look low to me. As for the rest of the numbers you will need to find a sensors.conf file that is appropriate for your board or do some experimenting with multipliers and the BIOS output.

Don't suppose anyone has an appropriate sensors.conf for Asus M2N-MX SE Plus? =)

Perhaps this can help:

At first glance this looks like a lot of work.

Also the iasl that is mentioned in the article is in portage
