There are tools to monitor CPU temperature under Linux. Most PC motherboards made in the last few years have included temperature monitoring. The biggest problem is that most motherboard makers include different "fudge factors" in their setup, so different mobos have different settings and finding the actual temperature can be tricky.

What I do:

• Don't worry about the accuracy of the temperature that's being reported. It has no bearing on reality. Instead, worry about relative temperature. First, get a baseline temperature when the system's stable but busy (half an hour into a large compile is a good time to take a reading).
• When the temperature's 10 above baseline, send a high-priority syslog message (which I have set to log locally, remotely, and wall to all users.) I use "Is it hot in here, or is it just me?" as my warning message. :)
• When the temperature's 20 above baseline, alarm and shut down cleanly.
• When the temperature's 30 above baseline, halt immediately. Better to fsck or restore from backup than melt the processor.

For linux, check out lm_sensors. It monitors fan speed, temperature, and voltages via the i2c bus or isa.

It works pretty well. I've noticed that my pus's +/-12 goes out of bounds often, but neither seems to affcect stability.

Have fun, but I suspect that the builtin sensors don't update often enough to detect a dirty supply.

On this subject, does anyone know of any Linux software that will monitor/report CPU temperatures? I've searched before, but with no luck, and I don't feel like disassembling one of the Windows ones...

Sure. Lm_sensors should be useful. I think that daemon which monitors the CPU temperature using it and runs desired commands also exists.

You sound like 'Eliza'.

Visit the lm_sensors page. Notice that i2c support is built in to the 2.4.* kernels, so you won't need the separate download for that, but you do need to have the basic i2c support compiled in to the new kernels. (It may already be compiled in if you have a stock kernel.)

Once you've gotten i2c support, just get the lm_sensors package and follow the instructions in the QUICKSTART file. When you're done, you'll have a hardware monitoring infrastructure, if your motherboard provides the info.

Various user tools tap in to that infrastructure to give you a live display or plot the data. I've already mentioned gkrellm; you can find more at the lm_sensors site's links page, or perhaps on google.

nifty little program called lm_sensors. Lm_sensors...not just for cpu temp monitoring anymore =)

you can get lm_sensors here you will also need the i2c package they have there. Screw RTFM, and just make and make install to the i2c source, then make and make install to the lm_sensors source. The default install is what you want, to compile everything as kernel modules and put them into /lib/modules/2.2.16. Then depmod -a

Now, just modprobe i2c-voodoo3, and modprobe bt869. Now, when you are in X, you can use the TV out. But wait...it's all static, how do I get it to work?

You need to add NTSC modelines into you XF86Config. there are as follows

ModeLine "640x480NTSC" 28.195793 640 656 658 784 480 520 525 600

ModeLine "800x600NTSC" 38.769241 800 812 814 880 600 646 649 735

and for all you PAL people (poor saps (^_^) )

ModeLine "640x480PAL" 29.50 640 675 678 944 480 530 535 625

ModeLine "800x600PAL" 36.00 800 818 820 960 600 653 655 750

Now, what I did was make my 640x480 Modeline NTSC all the time. That way, I could activate it by just a ctrl-alt-(+/-), and then programs like snes9x will automaticly use that 640x480, and be in NTSC mode. Remember, if you don't change your normal 640x480 modelines to the NTSC, and want to use them as is, put 640x480NTSC into your "screen" section of your XF86Config file. And also, as always, restart X after you change your config

That's it, have fun =)

Check out the LM-sensors project.

They have a pretty good ticketed support system. I think it's purely internal at the moment but you might be able to use it if you e-mail phil@stimpy.netroedge.com

Personally, i like the Mr T'Inator better ;-) Celeron 2 Overclocking Posted by timothy on Monday April 10, @11:40PM from the darn never-too-early-to-experiment dept.
