For about a half year I have had a Synology DiskStation 207+ running in my apartment. It does not make to much noise when idle, but when it is in use it makes a bit more noise. Currently my computer is silent as… a girl not talking, so why should a little piece of hardware like my DiskStation 207+ not be too?
Therefore I have started my own little project of making it silent. I will proparly have two or three parts depending on how the result after each part is.

I found a page on the SynologyWiki descriping a possible way to silent the DiskStation. In this step (the first step) I will therefore try and replace the fan, since the biggest problem is the noise from the fan when the DiskStation is running.

The page on the SynologyWiki are talking about a very silent 60x60x15 fan (16 dB) from PAPST (model 612F/2L). However that specific fan is impossible to find in a shop here in Denmark, so instead I found a post on a forum (I can’t find the link right now) descriping another fan that can be used as an alternative, a Revoltec Fan AirGuard 60x60x20 (25 dB). Eventhough the dB was much higher on the last one, I thought I would give it a shot since someone else has had good experience with it. I therefore ordered the fan.

I will in the next steps descripe how I replaced the standard fan with the Revoltec Fan Airguard:

Step 1:
Turn off the DiskStation DS207+ and remove all cables connected to it.
Sorry – I had to dummy-secure my guide

Step 2:
Remove the two screws placed on the back of the case (marked with a red circle around on the picture below), so the case can be opened.

Step 3:
Remove the four screws placed on the board (marked with a red circle around on the picture below).
When this is done you can remove the last part of the case from the board.
You will not need to remove the harddrives before this, but if you want to then do it.

Step 4:
Remove the fire screws placed on the back of the Synology-board. The screws are marked with a red circle around on the picture below.
The screws are holding the fan, and by removing these screws we can remove the fan from the DiskStation.

Step 5:
Unplug the fan from the DiskStation by removing the fan-connector from the socket.

Step 6:
Remove the socket from the board. The socket must be removed because the socket isen’t big enough for the new fans connector.
Be careful not to break the three pins that goes through the socket. I unfortunately did, so I had to cut the fans wire and solder it on the broken pins (the pins are very small now).
Put the new fans connector on the pins – it should go right on, so you don’t need to use force to do so.

Step 7:
Screw the new fan on the board, just as the old fan was.

Step 8:
Put the board onto the small part of the case, and screw it on, so it is locked to the case.

Step 9:
Take the second part of the case, put it together with the small part (that has the board attached) and take the two screws to lock the case.

You are now finished installing the new fan. Now install your cables to the DiskStation 207+ and turn it on.

I could hear a little bit of difference, however in my opinion not enough. I will in my next step try and install some noise breaking material to the DiskStation and see if that would make a bigger difference.

Please excuse my bad english in this blog.
