Temp monitoring lm-sensors

[Qqmike]

Anyone get
lm-sensors
(with ksensors front end)
to work in Kubuntu 8.04.2?

Mine is only detecting CPU Core 0 and Core 1 temps.
It is not detecting: CPU fan speed, or other Intel thermal zones (of which there are at least two ICH & motherboard), or any voltages & other hardware specs.

Motherboard:
Intel DG33FBC



> lim-sensors has worked for me in 8.04.2 using Intel D915GAVL motherboard.

> I'm told there is no problem in Ubuntu using a DG35 Intel board.

Re: Temp monitoring lm-sensors

Although I am on 9.04 RC, I am pretty sure that my ksensors has detected everything for the past few versions... all voltages, case fans, cpu fan, temps, etc.

AMD though.

I do love using it in the tray... very nice and compact way to watch performance/problems.

Re: Temp monitoring lm-sensors

lm-sensors has not shown my my fan speeds since 6.10 -- this is on an Intel D975XBX motherboard. Kind of a disappointment. It does show both CPU and GPU temps. And of course hddtemp takes care of hard drive temps.

Re: Temp monitoring lm-sensors

@ kjjjjshab: AMD could make the difference:

Quote from lm-sensors FAQ
(2009-01-08) The ICH8 (82801H) and possibly later Intel south bridges have embedded sensors. These are not yet supported, due to a lack of technical documentation and support from Intel. The OpenAMT project is supposed to help, but in practice not much is happening. Or maybe there is some hope?

@ dibl: Strange, yes, since everything works with my D915GAVL, but not your 975.


Just built the G33 system and would like to monitor the temps vs fan speeds vs manual fan controllers (4 case fans). It's a Linux-only box, so no Intel Desktop Utilities (via Windows).


Thanks for the input. Hopefully someone here has some data points on the D33 board (a couple steps behind the 45's but a very popular, no-problem Intel board -- I put the Intel E8400 in it w/4 GB RAM).

Re: Temp monitoring lm-sensors

Sounds like a nice system, Mike. I've recently built two Intel systems on Asus boards, one was a P43 and one a P45. I put E8500s on them. Sorry I can't shed any light on yours.

Re: Temp monitoring lm-sensors

Thanks for the input, dibl

If anyone gets a chance to check their BIOS on these newer boards, I'd be curious to compare the temp reading shown there with mine, particularly the ICH & MCH chipset.

(DG33FBC Intel mobo)
BIOS, Advanced > Hardware Monitoring:

Processor Thermal Margin 46 C
Mobo temp 46 C
ICH Temp 72 C
MCH Temp 68 C

CPU Fan 813

Re: Temp monitoring lm-sensors

So what are ich and mch readings?

These are the readings available to me:

Re: Temp monitoring lm-sensors

@toad

ICH = Input Controller Hub (~ kind of like "Southbridge")
MCH = Output Controller hub (~ "Northbridge)

Your zones look like mobo zones. Hard to tell without looking at thermal docs.
What motherboard do you have there?

Frustrating that lm-sensors isn't working on the DG33FBC board.

Re: Temp monitoring lm-sensors

Darn. You have an ICH10! I have just the ICH9, yet lm-sensors won't work for me.
Except, the quote I posted above may explain it:

May be fixed with newer kernel modules -- 9.04 ( ? ).

Re: Temp monitoring lm-sensors

You get any meaningful output from sensors-detect?

[Qqmike]

Re: Temp monitoring lm-sensors

Yes, but:
Mine is only detecting CPU Core 0 and Core 1 temps.
It is not detecting: CPU fan speed, or other Intel thermal zones (of which there are at least two ICH & motherboard), and it does not detect any voltages & other hardware specs.

The module coretemp IS installed, but I suspect the quote from their FAQ (above) tells the story.
(This is in 8.04.2.)

And, btw, in sidux
sudo apt-get install lm-sensors
returns "not avaliable ... etc."

Maybe it will work in II (=newer kernel modules), I don't yet know.

Re: Temp monitoring lm-sensors

I am currently running 2.6.29.1-3. Mind, I haven't subjected this mobo to Kubuntu yet. Let me know if you would like me to check 8.04-2 - I'll download the iso and stick it on Virtualbox

Re: Temp monitoring lm-sensors

"Let me know if you would like me to check 8.04-2 - I'll download the iso and stick it on Virtualbox"

Very nice offer, toad!

BUT, I'm afraid that would only/mainly check how well the devs at lm-sensors have gotten the specs from your mobo maker. But, then, maybe it would indicate something about the modules in 8.04.2?

Re: Temp monitoring lm-sensors

@Mike, out of curiosity I rebooted my Kubuntu system and went into my BIOS this morning to take a look at the hardware monitoring setup. In mine, when you get to the appropriate BIOS page, you have to hit "Enter" to display the current status. It will instantly show the CPU temps and also the CPU fan speed and the rear case fan speed (but not the other two, for some reason -- they show up at 000 rpms). It showed my CPU cores at 42 degrees C, whereas lm-sensors had them at 47. So there's a 5 degree "overstatement" on my hardware. Which is fine by me -- I'd rather have it overstating than understating.

So, my BIOS does read the fan speeds, but apparently there is no suitable module available for Linux/lm-sensors to use for that purpose. I think it was a prior motherboard (and BIOS version), also an Intel, that I first installed Kubuntu 6.06 or maybe 6.10 on, and that one did pick up the fan speeds and displayed them on the KDE system monitor of that version.

I've never seen the motherboard voltages displayed in Linux, like the Intel utility does for Windows. The new Kinfocenter for KDE 4 does pick up the actual (overclocked) CPU speed of 3.45GHz, whereas the prior versions simply reported the factory default speed for the X6800 of 2.93GHz.

That's the report.
