Fanless Aspire One

[esaym]

Well the good news is that I got my One today!

The bad news is that it is completely silent so you guys are on your own!

Yes the fan does fun always but this is the quietest laptop I have ever owned!

What model is that then and where from? We might as well still try to find a pattern...

It came from buy.com. It is white with intel SSDPAMM0008G1EA ssd, 2200mah battery, and 3109 bios

In ubuntu I'd currently put "acerfan off" in /etc/rc.local, although I haven't done it yet. I expect there's a similar thing in Linpus. When the "govern" thing is there I'll launch as a daemon in the same place.

Just now found how to set the default cpufreq governor to powersave too. Should help but that's a general thing.

I am using Ubuntu and I did put on /etc/rc.local but It isn't working

I am using the cpufreq since beginning, it's nice but I don't like the fact that it's just goes down to 50%... on Eee pc it was going to 12% - well, but 50% should help on battery run time and temperature

Yes,

Units with Samsung SSD = Noisy fan
with Intel SSD = Silence fan

Mine is a Samsung SSD and it's quiet....most of the time. Sometimes the fan spins up without reason and I can understand what some of you have experienced with your One's, but most of the time it's very quiet (I'm not very tolerant to noise and compared to my stationary PC, which everyone who's heard it experience as extremely quiet, the One is just a bit more noisy).

I would not characterize my fan as loud by any means, but it is not whisper quiet. Something that I've done that has helped a lot with the sound (and with the cooling) is to add some larger stick-on rubber feet to the bottom of the battery. They are about 1/2" square and close to 1/3" tall. This gives more air space under the AA1 which helps dampen the resonating sound the fan makes. This also helps with air circulation under the AA1. A secondary benefit is it angles the keyboard a little forward making it easier to type. With the larger back feet my AA1 still fits in the soft sleeve that came with it.

I know some will frown at doing something like this, but it's worked out for me.

Why would we?

OK, maybe you wouldn't.

I figured some will frown on adding extra thickness to a netbook since being so small is part of it's beauty.

I've written a simple daemon to automatically control the fan according to temperature.

It's on the wiki page (http://wiki.aspireone.net/index.php/How_to_hack_the_noisy_fan) now, and is called acerfand.

Try it out, guys. And someone fill in the bit about putting it into the local boot script on Linpus.

Is it possible to make this for windows?

GREAT Rachel!!

I did put it in /etc/rc.local (Ubuntu) but is not taking effect at boot time -- however If I run that script it starts running and I can see it If I do:

Code: Select all

pstree | grep acer
     |-acerfand---sleep

I didn't create the conf file for the script as I think that default values are ok

I am very happy to see that our problem were resolved with our efforts -- now the wiki page is a bit disorganized, Rachel, If you can, you can go ahead to clean it - just put as principal this daemon!!!

Eee pc have a great community (I have one) because we discuss on forums and finally we resume on wiki, but for AA1 is really bad because info is all disorganized - principal links on main site is for forum messages which are a pain to read and conclude something

My rc.local file is:

Code: Select all

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Economize the SSD

sysctl -w vm.vfs_cache_pressure=50      # Don't shrink the inode cache aggressively
