Talk:How to silence the DiskStation 207+ (or 209)
Removing the Fansocket works quite well, just pull it off carefully. No soldering needed.
Fan connector is a JST PHR3. Tested and approved.
You can also remove socket as said before, but do not forget this connector has a 2mm pitch, while PAPST connector has a 2,54mm pitch. This is a minor difference, but you have to take this into account if you directly plug PAPST connector on Synology connector: do not push the connector too deep.
Just changed the fan of my 207+ for a papst 612F/2L. Removed the socket of the mainboard and installed the new connector on the naked pins. The new connector is indeed slightly differented as stated by Michael, but it fits good enough for me.
It is difficult to install the original screws. Before installing the fan in the unit, I laid the fan on the workbench and screwed each screw in once completely to tap the thread. (aply a forward/backward motion. Once the fan has thread in it's holes, it's a piece of cake to install the fan with the original screws.
I ordered a fan for my DS207+, but I actually got a 20 mm fan instead of a 15 mm. Instead of returning it I mounted it on the outside of the case. I had to put the cable through the kensington lock hole, wich was a bit tricky. I also used rubber mountings instead of regular screws. With the fan in place, the fan noise was much lower and the temperature of my two harddrives actually dropped about 2°C from 31°C to 29°C.
