I have two Zyxel network storage boxes (NSA221). The fan died on the first one after a little over a year and the hard drives started over heating. I wrote Zyxel and they were basically clueless, their only solution was to send the whole unit back. I took it apart and got the size and wiring configuration of the fan (60X60X10, 3 wire) and ordered this little beauty from Amazon. Now the NAS is back humming along as quiet and cool as ever.Oh and if you have a NSA221 ..
The software automatically disables the Windows controls and installs a very easy to use application with more options than windows. All in all, a great little UPS. I got this one after returning a Cyberpower unit which was a piece of junk (I fell for the cheaper price but you get what you pay for!)
