On special request, here is a workaround for controling the fanspeed of the RN104 ( most likely the same on a 102). For this you will have to SSH in to the NAS.
Thanks to Moseleypj for doing the work.
First you create a file in /root with the name fanoveride. Put the following lines in to the file.
#!/bin/bash
## Variables ## FANPWMPATH=/sys/devices/platform/mv64xxx_i2c.0/i2c-0/0-003e/pwm1 FANSPEEDPATH=/sys/devices/platform/mv64xxx_i2c.0/i2c-0/0-003e/fan1_input CORETEMPPATH=/sys/devices/platform/axp-temp.0/temp1_input MAXFAN=100 # Maximum operable speed MINFAN=0 # Minimum operable speed MINPWM=75 # PWM Limit MAXPWM=255 # PWM Limit MINTEMP=35 # Min temp -> Fan slowest MAXTEMP=75 # Max temp -> Fan fastest NEWSPEED=50 # Initial fan speed (%)
################################################################### echo "Automatically controlling fan speed..." while true do getReadings echo "Temp: $CORETEMP C FAN: $NEWSPEED% [$FANSPEED RPM] [$FANPWM]"
start() { if [ -f /var/run/$PIDNAME ] && kill -0 $(cat /var/run/$PIDNAME); then echo 'Service already running' >&2 return 1 fi echo 'Starting service.' >&2 local CMD="$SCRIPT &> \"$LOGFILE\" & echo \$!" su -c "$CMD" $RUNAS > "$PIDFILE" echo 'Service started' >&2 }
stop() { if [ ! -f "$PIDFILE" ] || ! kill -0 $(cat "$PIDFILE"); then echo 'Service not running' >&2 return 1 fi echo 'Stopping service.' >&2 kill -15 $(cat "$PIDFILE") && rm -f "$PIDFILE" echo 'Service stopped' >&2 }
uninstall() { echo -n "Are you really sure you want to uninstall this service? That cannot be undone. [yes|No] " local SURE read SURE if [ "$SURE" = "yes" ]; then stop rm -f "$PIDFILE" echo "Notice: log file is not be removed: '$LOGFILE'" >&2 update-rc.d -f <NAME> remove rm -fv "$0" fi }
In my case i have the min and max temp in the script set to 35 and 75 degrees to create a nice fan response wich is not to nervous. If you set it between 40 and 65 the regulating becomes more agressive. Just play with the values for your needs.
Just curious.... What is your environment temperature and at what are your new average values for disc temp, cpu temp and at what revs is the fan running now?
I've set the range 35-65oc room temperature is around 17oc. Fan speed sits around 1300-1500 and I've seen a drop from 55oc on the drives to 37-39 and 70 to 50 on the cpu.
This is a great way to control the fan speed of the NAS 104 and to bring down the temps which is always high.
I would like to ask, whether does it effect the FAN in anyway, I mean is the FAN meant to run above the current spinning speeds. Or what is the maximum RPM the FAN can spin on RN104? My fan spins at 700-850 RPM with CPU Temp @ 65-70 C & HDD's @ 45-50 C.
I have already exchanged (under warranty) my NAS in which the FAN was dead after 6 months of purchase. So, was worried if anything goes wrong.
Kindly reply to this as, I am very much eager to get the temps of cpu and hdd's down from those levels.
Hi all Looking for a bit of help. I have an RN104 NAS, have created the 2 files listed in the first post, set them to 775, done the update-rc.d and when I try running fanoveride I get the following:
root@JTS104:~# service fanoveride start env: /etc/init.d/fanoveride: No such file or directory
root@JTS104:/etc/init.d# service /etc/init.d/fanoveride start /etc/init.d/fanoveride: unrecognized service root@JTS104:/etc/init.d#
I am running OS 6.1.8 Just to confirm, does it matter that I created the above files in Windows Notepad (win 7) and then SFTP the files in place (hehe and I did remove the .txt extension before copying over)?
Also, when I do the update-rc bit I see the following:
root@JTS104:/etc/init.d# update-rc.d fanoveride defaults update-rc.d: using dependency based boot sequencing insserv: warning: script 'istat' missing LSB tags and overrides
Most likely that Notepad is the cause. You should use a Linux compatible editor, like ultraedit or something like that, or edit on the nas self using "vi" Option 2: I am not shure if dos2unix is present on the nas, if so then you can try: dos2unix fanoveride. Do this for both files. Or make new files 🙂
As per the details given here I created the files at their respective places. The update was successful and the FAN speed increased from 800 to 990, temperature reduced marginally by just 2 deg C.
But when I manually use the commands to stop and start the service by using the following command... root@ReadyNAS_RN104:~# service /etc/init.d/fanoveride stop
I get an error... /etc/init.d/fanoveride: unrecognized service
The files were created with Notepad++ as suggested by Stephen.
Finally got the error rectified. It was due to an extra character in the file. I have changed the MAXTEMP=65 instead 75, so that the FAN spins a bit faster.
Now, the issue is when I issue the command... service fanoveride start
I get the message... root@ReadyNAS_RN104:/etc/init.d# service fanoveride start Starting service. Service started
Everything looks fine, but the FAN speed is yet 990, the temps remain same and not decreasing.
Surprising thing is that when I issue a command... service fanoveride stop
I get the message... root@ReadyNAS_RN104:/etc/init.d# service fanoveride stop /etc/init.d/fanoveride: 29: kill: No such process Service not running
This says that the Service is not running...
Request some guidance here.
Current temps... CPU: 67 degC HDD: 48-51 degC FAN RPM: 990
Woohoo - thanks guys - its now working for me 😄 I tried Note++ and still got the same error message (saved the file as a *.* type) so went into Vi on a terminal (using the GateOne app) and as you guys said, the carriage return was being a problem - each line had ^M at the end so I deleted those and tried the steps again and all now working great - the fan spun up to 2500RPM within seconds using a max temp of 75. The service can be loaded and unloaded with no problems
Seriously thinking about changing max temp to 65 though (anyone have any thoughts on dropping the max temp that low?) - my NAS is tucked away in a room where the noise is of no bother to anyone - it now seems to be idling at the following rate:
Fan - 1241RPM CPU - 53 Disk 1 - 37 Disk 2 - 39 Disk 3 - 40 Disk 4 - 37 (these are 2Tb WD Red drives) Saketb - if you want I can email you over the 2 files that are working for me? That might help you

Its great to hear that its working for you and that the temps have come down considerably. Mine, seems to not work and temps have risen to 70+ on the CPU. The service does not work.
Request you to email me the files so that I can copy them to the respective folders and start the service. (sent you a PM with my email)
One thing, I would like to ask... the files I created was with notepad++ and then deleted the ^M and saved them again in Vi. When listed with ls -l it shows...

Are these correct? Is the guest guest correct? Is this why it is not running?
Request you to help me here, as I'm really worried about the temps and the device.
Thanks.
Will send the files in a few minutes.
That guest guest thing is probably the issue. My files are there by root root. I would suggest the following:
1. Install Bitvise SSH Client (from http://www.bitvise.com/download-area). 2. Load SSH Client and log into the NAS with the Root account (using root as the username and your NAS password as the password) 3. Drag and drop the files I send you to correct directories. 4. Right click the files and change permissions to 755 5. Run the update-rc.d fanoveride defaults command 6. Start the service 7. Check the admin page to see if the page has changed speed 8. Try stopping the service to make sure it unloads ok (remember to restart it too though 😉 )

Thanks a million. Finally, got it working.
Used Putty for ssh access and transferred the files. Changed the MAXTEMP to 65 and now the temps have come down drastically. FAN RPM 1706 CPU 53-56C HDD1 42C HDD2 43C HDD3 41C
Though, the files yet show guest, guest. Thats surprising....

Your welcome Wow - thats great that it worked. I thought the guest guest permissions would have done it but oh well I changed the MAXTEMP to 70 in the end and now im seeing the following: CPU: 50 Fan: 1365 RPM Disk 1: 35 Disk 2: 36 Disk 3: 37 Disk 4: 34

This is a different way of dealing with the heat issue. Hope it helps.
I have just purchased a RN104 to upgrade from my older ReadyNAS NV+. I first set it up with four 2TB drives and have now one by one through the past week have upgraded it to four 4TB drives. At first I was dismayed to see that the drive temperatures were 45 to 50 C, and the processor was 65 to 70 C. The fan never spun up over 790 RPM. I checked on line and found that these were pretty much standard temperatures. I have a solution where even after 160+ continuous hours of thrashing to rebuild the array and reshape the data as each drive was replaced, my hard drives are running 32 to 35 C, and the processor runs at 43 to 45 C. Now, at idle, the drive temps are holding at 32~33C, and the processor is at 40~42C.
Here is my "fix": I got a 92mm double ball bearing 12VDC fan that moves 56CFM (70,000 hour MTBF which is what, 8 years?) and mounted it on the back of the case with some 3M indoor outdoor double stick foam mounting tape where the built in fan exhausts, and used an old 12VDC power brick from something long gone. No re-programing, no opening the case, no voiding of my warranty. Now I don't care what the built in fan is doing. Many will say this is an inelegant fix, and it may well be, but for $6.0 7 U.S.D. list price for the fan, I will call it a simple solution. My ReadyNAS is set in an area where the noise of this fan doesn't bother me at all. I use it as my whole home media server, streaming mp4 video and mp3 music to 5 or 6 different places throughout the house, which really isn't a strain on the unit. I think the temperatures I have achieved speak for themselves. I hope this helps other people out there who, like me, think that heat is the enemy and leads to hardware failure sooner rather than later!
Does anybody know where to scrape the HDD temperatures from? I'd like to base the fan control on hard drive temperature rather than CPU temperature.
EDIT: Okay, getting it from smartctrl
I set MINTEMP=28 and MAXTEMP=36 for HDD temp limits. I changed CORETEMP in the getReadings function to : CORETEMP=$(/usr/sbin/smartctl -a /dev/sdb | grep Temper | awk '{print $10}')
sdb is my middle drive, so tends to be hottest. The rest of the loops in the code I left alone. This seems to be keeping my fan around 1500 RPM and HDD at 33 degrees. I don't run any CPU intensive stuff , so I figure this should be safe CPU-wise, since there should be a rise in HDD temp that would increase the fan to cool the CPU as well if anything is going on in there.
