Fan Control Documentation, Buffalo LinkStation Live
The cooling fan of the Linkstation can be controlled in speed in 4 steps. Also the rotating speed could be read out. In case you have a failure, in the #Hardware section, technical details and supplier links are documented.
An extensive description of the /usr/local/bin/miconapl commands are in the file:
With the function fan_set_speed [stop|slow|fast|full] the speed setting can be either set or read out:
root@NAS-100:~# /usr/local/sbin/miconapl -a fan_set_speed fast or root@NAS-100:~# /usr/local/sbin/miconapl -a fan_set_speed #[miconapl.fan_set_speed] fan_speed=slow
With the function fan_get_speed the rotations per minute could be read out:
root@NAS-100:~# /usr/local/sbin/miconapl -a fan_get_speed #[miconapl.fan_get_speed] fan_rpm=1800 Values: stop = 0 rpm slow = 1800 rpm fast = 2500 rpm full = 3500 rpm
With the function temp_get the temperature in degree celsius could be read out:
root@NAS-100:~# /usr/local/sbin/miconapl -a temp_get #[miconapl.temp_get] temp=33
As decribed in http://www.mztn.org/kpro_memo/kpro_micon.html the temperature (degree celsius) control looks like:
stop - 20 slow 20 25 fast 25 35 full 35
The function syntax of the Buffalo /usr/local/sbin/miconapl program.

micon_get_version returns something like "mcon_version=LS-GL Ver1.00" without the quotes.
- Not all linkstation mainboards have a buzzer/beeper soldered on.
- The fan speeds are approximately at "full":3500rpm, "fast": 2500rpm, "slow":1800rpm, "stop":0.
- Not all boards support fan regulation, fan_get_speed returns "fan_rpm=Fine" if the fan is rotating.
The initialising at boot time is done from script /etc/init.d/miconmon.sh

2007-04-15 danmiles, Replacing Linkstation Fan Just finished changing out the fan in my Linkstation 250. A couple of notes on the instructions given elsewhere...
- The exact replacement fan is available from Mouser Electronics
- You have to peel off the front panel overlay to find the two small screws that hold the U-shaped band around the case. When I removed the panel on my Linkstation there was enough "sticky" left to put it back on when I was done. (Note that the two screws are really tiny - about the size of a grain of rice. You will need a cross-head jeweler's screwdriver to get them off. The screwdriver in an eyeglass repair kit might work as well.)
- The U-shaped band is held on to the case with L-shaped clips on the top and bottom legs of the band. After you remove the two tiny screws hidden under the front panel overlay, slide the U-shaped band toward the front of the drive (I had to pry mine with a screwdriver) then lift the top and bottom arms up until the clips clear the case and the U-shaped band should come right off.
- To open the case, press in the tabs that lock the sides together and swing the case open like a book where the front panel is the spine of the book and opens last. The two halves of the case should come apart easily leaving one half containing the electronics, drive, etc.
- The fan is held in with plastic clips built into the case. When you remove the fan note which side the label faces so when you install the new fan you can get the airflow in the right direction
- There are three wires on the fan - red, black, and blue. I simply cut the wires to the old fan and spliced in the corresponding wires from the replacement fan.
- When you reassemble the case, be sure that the power switch on the front panel is aligned with the corresponding hole in the front panel of the case.
07-Jun-2008, 09:12 AM #19 rradarr Try some oil! Hi - I've had the same problem with my Linkstation, but I've managed to return it to it's original as-new silent running with a clean and a small drop of sewing machine light engine oil. I still took the unit apart first, used an air spray to remove the dust, and then carefully applied the oil into the hub. Saved me a fiver on the fan with p&p. By the way - don't use WD40; it's not suitable for this task.
