Fan is Loud #36

How do we quiet the fan? 

Some say:

Option "RegistryDwords" 
"PowerMizerEnable=0x1;PerfLevelSrc=0x3333;PowerMizerLevel=0x3;PowerMizerDefault=
0x3;PowerMizerDefaultAC=0x3"
Option "OnDemandVBlankInterrupts" "True"

@gle, nice write-up.

Interesting that enabling c3-c6 has helped quiet your machine; everything seems 
to point to the noise coming from cpu-state constantly going between power save 
and full throttle. 

It must be that fixing cpu cores to "scaling_governor = powersave", pins 
cpu-state in c3-c6. In other words, cpu cores are permanently downclocked 
(which kind of defeats the purpose of having a quad core CPU since max ghz is 
already slow, 1.87ghz in my case on an F12 signature series)

Anyway, how are things now in Linux a week after your patches? I'm particularly 
curious to know how things are if you run for a week straight without 
rebooting; i.e. just suspend/resume.  I start out quiet on reboot, but later 
that day, the noise returns (nothing like before, but still this up & down 
sound which is not the fan, but something else, and constant----ly irritating, 
lol, love this machine, but man, it would be laptop nirvana without this f-ing 
noise)

@gle, enabling c3/c6 in the bios and setting intel_idle.max_cstate=6 in grub 
conf has had a positive affect on the noise ;-) CPU core temps are also down 
from 47 degrees celsius to 43 (forcing max cstate of 2 at bios & grub level 
keeps cpus pinned in max power consumption and therefore heat generation)

Still this winding up & down subtle grinding sound, but less than before which 
is nice -- enabling higher cpu idle states does the trick, probably the best 
you can do in linux on this machine (downclocking the gpu is of course a must). 

Far from MacbookPro quiet, but with the collected patches here, a vast 
improvement over out-of-the-box-post-linux-install noise nightmare.

The true benchmark will be how the noise level changes when running without 
restarting for days (or weeks in my case) and relying on suspend/resume (which 
is rock solid on Fedora 14, btw)

Thanks again for the collected breakdown on the various patches, particularly 
the bit about c3/c6 actually reducing noise factor (was under the impression 
the noise was caused by constant back & forth between power saving and 
non-power saving states)

@sit1, thanks for your feedback, nice to hear that some of my settings did help 
you also, to answer your question I can't test if the fan noise remains quiet 
after a few days without rebooting, as I use my laptop between work and home 
with virtual machines on Virtualbox and Ubuntu 11.04 doesn't hibernate / resume 
correctly with VirtualBox machines running or have been running during session 
(unlike on Windows) so I have to fully shutdown and restart twice a day. It 
seems that suspend / hibernate and resume had improvements on Ubuntu 11.10 but 
I had to downgrade back to 11.04 to avoid all the defects I found on Gnome 3 
and Unity interfaces (waiting for 12.04 LTS or any more mature version of Gnome 
3 :-) So I don't know if the fan noise remains quiet after long sessions, but I 
noticed that it does at least after 24 hours up.

Definite noise improvement with your enable c3/c6 suggestion ;-)

I'm on Fedora 14 and am holding off until Gnome 3 issues are sorted out.

re: sleep/resume, rock solid here, but I don't use the GUI to enter sleep mode, 
I use a terminal alias "gosleep" that calls "acpitool -s"

100% reliable, have done a couple thousand sleep/resumes with the above ;-)

Have not tried System > Shutdown > Sleep since Fedora 13, worked maybe 50% of 
the time for me, so had to search for another solution.

This is the greatest thread ever! My Vaio VPCF11S1E/B has sounded like a hair 
dryer from day one. I've basically put up with it and worn headphones whenever 
I use it (otherwise I'm left with a ringing sound in my ears after 30 or so 
minutes of use).

I haven't tried the C3/C6 settings yet, but will do when I get home. I'm using 
Ubuntu 12.04, and this is what I did to silence the unit:

1. Install the CPU frequency setting app: sudo apt-get install indicator-cpufreq
2. Restart the computer.
3. Set the CPU frequency to 0.93GHz.
4. Run on two cores: echo 0 | sudo tee /sys/devices/system/cpu/cpu2/online
5. Physically removed the 2GB RAM stick.

I can now use my Vaio VPCF11S1E/B without using headphones!

why have you remove 2gb ram ?

I removed the 2GB RAM stick because RAM generates heat. I'm not sure why, but 
it definitely makes a huge difference. I will post a video to YouTube later 
this evening showing the difference between running my Vaio with 4GB and 6GB. 
This difference is significant.

ok I did not see any difference between 4 and 6 GB of ram, I have a f11s1eb but 
 between ubuntu 12.04 and archlinux; on ubuntu 12.04 the pc much less heating, 
a check in the long term

Any suggestions for Windows 7? I dont really use Linux

Thank you!

My F12 serie Vaio was shutting itself down because it was overheating. I have 
cleaned it with a compressed air and the noise and overheating problems are all 
gone.

Do you need to take it apart to do so?

Hi guys! My F11 was hitting over 70 degrees,

I took it apart and cleaned the hell out of my fan and now I'm below 50 the 
whole time!!

Great results didn't expect it!

Yeah!

Couldn't find a solution for the fan noise. I took it apart and cleaned the 
cooling system and the noise is gone.
