Replacing the fan in ReadyNAS Duo - possible?

I don't know about the cables, but the fan pulls air out the back. You should be able to feel the current when you place your hand about 1" away from the fan.

@supertix

Yes the fan should pull out the air. That's why there are holes in the hard drive door at the front.
You might not need the Noctua cables, you can experiment with the EnableFanMinRPMOverride add-on

The be quiet - SilentWings USC - might be the worlds best 120 mm fan.

I will try it

My DUO started posting fan errors in the log. After a couple weeks of on and off fan errors, I took the DUO apart to remove the fan which I took to the local computer store. They sold me a fan that was actually thinner than the NAS fan. They said the fan they sold me was more than capable as far as CFM and was also quite. I installed the fan and have not had any errors logged for the fan and the temperature of the two drives are in the same range as I saw on the Health page in Frontview before the Factory fan started having errors. The fan has been in the DUO for almost 6 months and not one error for HD temperatures or the fan speed. Also, the fan is quite to the point I cannot hear it. My DUO is located on a wooden shelf in front of me and slightly above my head.

I bought my Duo last friday. I haven't read this thread before buying.
I did find out that the fan is noisy and just ordered a Papst fan : 38€ :-( (shipping included)

Wil update you when I install it.

Hi all,

I just installed a Fractal Design 60mm silent fan given the feedback i saw in some forum posts.

The first feedback is that it is in fact more silent then the stock CROWN AGE06025B12U but even after calibration i don't get reasonable lower RPM speed :cry: :
These are the reading 10min after a reboot:

Disk 1 WDC WD20EARS-00MVWB0 1863 GB , 26 C / 78 F , Write-cache ON
Disk 2 WDC WD20EARS-00MVWB0 1863 GB , 27 C / 80 F , Write-cache ON
Fan 1 2027 RPM

I will monitor closely the HDD's temps to avoid any problems... I do remember that the original operating temps were around 36C-37C (under heavy data writing/reading).
I am also aware that the original fan would draw more air and support higher rpm.

I will keep testing and let you guys know the results.

Look forward to hear any feedback either way :D

UPDATE:

I have to say that even with the same RPM as the stock fan it is much much much more silent than before! This upgrade is highly recommended!!!

Disk 1 WDC WD20EARS-00MVWB0 1863 GB , 30 C / 86 F , Write-cache ON
Disk 2 WDC WD20EARS-00MVWB0 1863 GB , 30 C / 86 F , Write-cache ON
Fan 1 1666 RPM

I believe that the 2000 RPM from my previous post occurred because of multiple refresh that i was doing to the webGUI of the ForntView. I also believe that the fan speed is influenced by the ReadyNAS DUO CPU temperature. Can anyone confirm this?

I have also installed the Fractal Design 60mm fan. The most complex piece was finding the right screwdriver!

It's been installed for a couple of weeks now and is significantly quieter than the stock fan. In terms of temperatures they seem a bit lower than the stock fan

Disk 1 Seagate ST3500418AS 465 GB , 30 C / 86 F
Disk 2 Seagate ST3500418AS 465 GB , 29 C / 84 F
Fan 1 1630 RPM

All in all I think this is an excellent upgrade

If anyone is thinking of getting rid of this device because of the noise: I followed the crowds and purchased the Fractal Design 60mm Silent Series Cooling Fan [ASIN: B003ZVTS4A]

I could't believe the difference. Now I have the device on a book shelf where I can access the usb ports.

There is a utility you can install to set the minimum fan speed (a link is posted earlier in this thread). I have mine set at 1500 rpm with a 80 mm Nexus fan and it never gets up, not even on hot summer days, keeping the HD's at a comfortable 31 - 38 deg C.

Remember that the optimum disk temperature is between 30 an 40 deg C. Lower will shorten life time.
