Replacing the fan in ReadyNAS Duo - possible?
Hello. Has anyone replaced/changed the (stock) fan in the Netgear ReadyNAS duo? I would like to do this, since I think the fan makes far too much noise. Any comments and thoughts about this is w...
Indeed, the Duos are not quiet...
To ReadyNAS modders... ;)
But on my side, my concern is about the fact that one of my 2 ReadyNAS Duo has a fan with a rotating speed fluctuating constantly :
When idle, the sound generated is varying every 1-2 seconds, and this is quite difficult to handle. The other ReadyNAS makes a steady sound and it is easier to accept.
My ReadNAS units are stored in a quite fresh closet (still perfectly dry...). Gaining a -10°c approximatively, regarding temperature in the rooms I live in : no more than 25°c during Summer, and down to 15°c at winter time. Despite the 15°c ambiant, fans still rotate at 1550 RPM approximatively (at the lowest, Drives are in sleeping mode).
Digging into PDF specs (see link page 1 of this thread), I'm assuming the AGE06025 is rotating at 1500 RPM when 7V are provided and up to 5000 RPM when 13V. With the max RPM, we have 0.726m3/min and 33 dBA (!).
ReadyNAS Duos are not built to be quiet with such fan. No matter how low you go on minimal RPM here...
I'm planning to make a significant move by replacing the fans but as the replacement parts recommended in this thread are difficult to find in my country (France), I'll probably give a try to the following solution :
As I didn't open the case yet, I'm here supposing we have a standard 3 pins plug (ground/current/RPM). To be confirmed...
I want to replace the provided noisy 60x60x25mm fan as follow : I will use a 80x80x25mm fan with a 80>60mm adapter, all mounted externally.
So far, my choice (based on good experience with other models from Noctua I use in my Computer case (and they are easy to get in France)) goes for the Noctua NF-R8 :
See specs here : http://www.noctua.at/main.php?show=productview&products_id=9&lng=en
4-13 voltage range, 0.11 A max, 800-1800 RPM, from 0.43 to 0.88m3/min and... 7 to 17 dBA!! Seems interesting, isn't it? 8)
So... I want to hear your feedback and please tell me if I 'm missing something before giving a try to this... Excepting the lose of Netgear warranty, of course! :wink:
Actually, my concern is how RAIDator will handle the voltage/RPM ratio as it will be quite different with the Noctua. But I'm relying on fact that Fan Calibration is meant precisely to adjust this ratio (my assumption). Then, another concern is RAIDator expectation regarding given RPM and air flow (i.e. lowering HDD temps), but the Noctua is a better air mover so effective efficiency should be better than software coded "expectations".
What do you think?
[edit] Regarding voltage/RPM ratio and Air flow... Fan calibration makes me think RAIDator is driving Fan by RPM, obviously. So RAIDator will probably never reach the max RPM it expects, the Noctua Fan will rotate to its max speed (1800) most of the time (but moving more air than AGE06025). And even when RAIDator wants 1500, we are still close to Noctua max RPM (still quieter than AGE06025).
