Re: [Solved] Asus L1366 mobo, cpu fan speed control

If you can't find the solution to this issue, I'd recommend not using the stock cooler; it isn't very good anyways despite looking flashy.

I invested in a Coolermaster V8 and am very happy I did so.  It keeps my CPU almost at room temperature at idle and at full load, my cores never go above 50C (and the whole chip doesn't report anything higher than ~35C).  The Core i7 920 CPU is overclocked to 3.2GHz.

But the thing about this CPU cooler that I especially like is that you can control the fan speed manually with the included potentiometer.  At its lowest speed, the CPU fan is barely audible and at the max speed, the only sound you hear is from the pushing of air (very little whining).  Frankly, I don't trust my BIOS or OS enough to let it control the speed of my fans.

Re: [Solved] Asus L1366 mobo, cpu fan speed control

Hi, jwcxz, thanks for the reply.

The first thing I did after receive my i7 920 is throwing away the stock cooler. I use Scythe MUGEN-2, which is better than your v8 according to many benchmarks on line in terms of thermal and audio performance smile  I use a front panel fan speed control to control the case fan speed, but would rather leave the cpu fan speed control to BIOS and/or OS. This is NOT without reason.  It is highly suggested by many people (I also believe so) that the CPU fan should be left in automatic control.

Windows-7 is doing the job excellently, fan is running from 400rpm - 600rpm idle and spin up to 1200rpm under load, and CPU temps are great, they are not what I worried about.

But at this moment, under linux, the fan is running 1100 rmp up just in idle while the cpu heat sink is cold as stone, well the CPU temp is thus about 2-3 lower in linux than in windows, but the problem is that it is totally not necessary to do this. It seems that right now linux is over-doing it. Remember that linux did wonderful job for old processors like AMD and Core2Due/Quad series, which is the same performance as under windows.

I hope some one who really know how this stuff works shed some light. It may be a very simple matter.

Re: [Solved] Asus L1366 mobo, cpu fan speed control

I've just built a i7 setup for my mother and can't thoroughly test linux on it as she will be using Windows. But I gave it a quick test drive with the ubuntu live cd.

Relevant specs:
* Intel Core i7 920
* Msi X58 Pro-E

I don't notice any ramping up of the cpu fan at all. I'm using the latest available bios. The cpu fan cooler (Scyte Mugen II) is running at aproximately 600rpm.

Re: [Solved] Asus L1366 mobo, cpu fan speed control

Hi, that is indeed very good news.  Which Ubuntu are you using? the new alpha release or the old Janty?

Then it seem that this issue only occurs for ASUS motherboard now sad

Re: [Solved] Asus L1366 mobo, cpu fan speed control

It's Ubuntu 9.04 (Jaunty). I'll pop in Arch's live cd as well. As I've mentioned before, I won't be able to install anything on it but I guess the fan speed behavior wouldn't suddenly change when I'd actually install linux.

Re: [Solved] Asus L1366 mobo, cpu fan speed control

with the new release of kernel 31, has anyone tried it?
Does this issue go away in this new kernel?

I don't have time to test it at this moment, if someone does, please report, smile

thanks.

Re: [Solved] Asus L1366 mobo, cpu fan speed control

I forgot to report back with the results of the ArchLinux livecd. As expected, it booted without any problems (no fan speed issues either). Here's the clean dmesg if you're interested: http://www.nepherte.be/files/dmesg

Re: [Solved] Asus L1366 mobo, cpu fan speed control

Hi, guys, finally I got some time to carefully investigate this matter. This problem happens only for ASUS mobo owner, and the problem is rooted in the ASUS motherboard driver:

asus_atk0110

which is loaded automatically ( I guess by udev), this driver provides wrong CPU diode temp, thus force the fan spin almost twice than necessary. In some cases, it even shutdown your computer due the extremely wrong high temp.

Thus solution is of cource to blacklist this thing in your MODULES in /etc/rc.conf, but instead load

w83667hg

trhough lm_sensors, this way, you will have an accurate CPU diode temperature, and your CPU fan should run normally now.  Mine now is idling at 500 ~ 600 rpm, the same perfermance as under windows 7.

Cheers!

Re: [Solved] Asus L1366 mobo, cpu fan speed control

I'm having a very similar problem, except I'm using a core i5, this did not happen in Debian testing until they upgraded to kernel 2.6.32 from 2.6.30, I'm currently using a fully updated version of Arch Linux, the fan noise drives me nuts, it is not that loud in Windows XP or 7. It automatically loads asus_atk0110, but w83667hg can not be found, is it provided in a different package or is it just not in 2.6.32? This is with an ASUS P7P55D LE mobo.
Edit:
I hope this slight thread necromancy is OK.
Edit 2:
Found this in the wiki, maybe it will help:
http://wiki.archlinux.org/index.php/Lm_ … E.3D2.6.31
Edit 3:
Doesn't seem as loud anymore, now it reports it's only at 1068 RPM, windows and Debian testing (when it was working) still were quieter though.
Edit 4: Hm, I think I'm going to try kernel26-lts.
Edit 5: Nevermind, it was my video card, not cpu fan, even though the reported cpu fan speeds seemed a little high, now it's nearly silent and my keyboard is lowder than my computer. I downgraded to xorg 1.6 and intalled catalyst from the aur, editing out the conflict with libgl, because xorg-server required libgl and catalyst provided it, so I simply removed it after installing catalyst, which solved that dependency problem, supposidly fan speed control with the ati opensource driver is in 2.6.33, or was going to be in it, 2.6.33's not in the repo's yet, but that would be nice.
Edit 6: Scrolling in  firefox is a bit slowish though, I think there were a few patched xorg-server packages in the aur to fix that, or some other problem.
Edit 7: That's with compiz I think, this is unrealated, I'll just deal with it until I can use the opensource drivers and Xorg 1.7 with fan speed control, the noise problem was much worse than the slow scrolling problem.
