Hello,
I just install 12.2 on a Dell Inspiron 5520 and I can not manage to stop the fan or reduce the fan speed.
It’s always running at maximum speed.
Can someone support? If you need more information please just ask.
Best,
Miguel

a few of questions:
have you ever run this hardware with any Linux and had successful fan
control? (which?) if you ran a previous version of openSUSE, did you
have this kind of problem then?
is your CPU set to always run at full performance? if so, set it to
automatically scale back when full performance is not required
is the fan reacting to high CPU/internal temperature? or, is fan speed
not modulated with temperature rise/fall? can you monitor internal temp?
if the machine is over a year old and you operate it in an even slightly
dusty environment you might have partially blocked air flow passageways
and dust coated internal parts–have you followed the manufacturers
recommended cleaning instructions?
have you been through the relevant previous 5520 threads in this forum
and not found a smile? if not, please have a look here

or perhaps one of the many threads on Dells would be helpful:

first of all thanks for your support.
I already spend some time reading. Anyhow I still have problems…
I will answer to your questions and than try to give some further information.

No, this is a brand new laptop.

Is set to normal operation. actually the temperature values are quite ok.
is the fan reacting to high CPU/internal temperature? or, is fan speed
not modulated with temperature rise/fall? can you monitor internal temp?
I can monitor temp (results bellow) but the fan control somehow is not active.

No, like mention above is brand new.

I did read a couple of articles and forum entries but none of them was clear about it.
4 years ago I had a similar issue with my Toshiba, at the time I just had to activate a new module on boot. This time I am not sure.

Can you support or give some hints about about manual configuration of ACPI fan control?
cheers,

i do not know if any of these will help…
i am also not certain that all are safe for your machine–while i do not
believe any will be harmful i want you to read the warning in my sig
before doing anything i suggest…
if it were my machine i would try each of the below one at a time,
this way: at the first green screen during boot up press the down arrow
(this just stops the boot process so you can type into the “Boot
Options” line) then type one of below and press enter…and, as soon as
the machine is booted i would open a means to monitor CPU temp and load,
and do that for a while…i would watch and hope the fan was quiet when
the CPU was lightly loaded and cool, and the fan would get progressively
louder if the CPU temp climbed…and if the temp climbs too high i would
shut it down *
acpi_osi=Linux
acpi_osi=Windows
acpi.power_nocheck=1
acpi=off
noapic
nosmp
nolapic
if none of that may be helpful and you may be forced to use the
operating system which came on the machine–at least until such time as
Dell is willing to help you run Linux on their hardware…
which brings me to: maybe some more reading and you will fine the best
answer…
by the way: Dell sells hardware with Linux installed–on those, i do not
know if Windows will run easily, quietly, etc–or not…

Well… I try those boot options without success.
Seems that I will have to wait for a new kernel… &/Or support from Dell.
Does anybody has different ideas?
Just signed up to reply. LMAO @ multiple Novell redirections and need to opt out of marketing emails 
I’m using LMDE (Linux Mint Debian Edition). Despite that, I believe the issue is kernel-level, and have confirmed the following works (in stopping the fan, and running less often) with kernels 3.2 - 3.5 
echo “min_power” | tee /sys/class/scsi_host/host*/link_power_management_policy
typically one only needs to do it on host0, but it doesn’t hurt to do it as above, just to be sure
since this happens to be a laptop, this may be a good idea anyway as it shaves a good 0.7-1.5Watts off your power consumption when you running on batteries.
if your wireless isn’t working, (broadcom 43142), you need unreleased dkms driver from dell, which was only available in factory-installed ubuntu oneiric. To get this driver to compile on 3.2+ kernel, a change was needed, and for 3.4-3.5, another change was needed. I updated the deb, and removed references to “oneiric” as the package was no longer ubuntu/oneiric specific. also updated md5 of changed file. (Details , Download)
N.B. If your laptop came with Western Digital Blue drive, check drive’s SMART data and make certain Load_Cycle_Count (attribute #193) isn’t increasing rapidly (like 50 / hour or more).
smartctl -A /dev/sda | grep ^193
If it is, your drive may also be factory-shipped with 8sec “IntelliPark”, which is a really bad idea if there’s something accessing your drive every few seconds, as the drive will repeatedly park and unpark which will inevitably shorten your drive’s lifetime.
There’s wdidle3 tool from WD (DOS only), and there’s idle3-tools package (executable idle3ctl) for linux, for changing the timeout in the drive’s firmware. You can increase the idle3 timeout to something sensible, at least 2-3 minutes. Glad I noticed this early on
just my 2 cents with this laptop so far.
Ah, another thing to help with power/heat, is power savings options of the integrated GPU - intel HD 4000 kernel module; i915
options i915 modeset=1 i915_enable_rc6=1 i915_enable_fbc=1 lvds_downclock=1 semaphores=1
modeset is necessary (along with opensource radeon driver) for vgaswitcheroo to work. that way, you can disable the discrete graphics when not needed via:
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
echo MIGD > /sys/kernel/debug/vgaswitcheroo/switch
echo IGD > /sys/kernel/debug/vgaswitcheroo/switch
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
This 2nd OFF may not be needed, unless scripting, to avoid possible blanking on resume. You may want to run this in startup, for default boot to be more energy efficient (and quiter fan operation).

yep, we complain and complain and still it is what it is…
slowly we make progress to get the Corporation out of our community
(but, we do need their help with lots of things, so we don’t push too
hard)
on the other hand you can post as i do via nntp and not do any multiple
anything by Novell!! see
