Synology Diskstation thoughtfully tells you when the fan is not working. It's better to know that the fan is dying before you cook the discs. Mine has been out of service intermittently for several months. I blew the dust out and increased my speed, but knew I didn't have much time when I went shopping and landed on the Noctua. that rotates every minute of the day and protects all your data. Comes with a wide range of fasteners. I preferred noise deadening nylon rivets to screws. There's also a variety of cable adapters, allowing you to choose what you connect it to and trade cooling performance for noise. This is where Synology's monitoring was very helpful, allowing me to choose the balance between noise and warmth. I don't normally go through the packaging, but in this case even the box (and the excessive amount of plastic - an environmental sigh) tells you this isn't a one-size-fits-all product. The wide range of mounting hardware and electrical adapters makes this a solid five star product for me.
