I don't know specifically, but it comes with a 4 pin fan, and has a 4 pin header.

*) health - added limited manual control over fans for CRS3xx, CRS5xx, CCR2xxx devices Considering I complained about this on the CRS310 very recently, I was pretty happy to see this implemented already... sadly it doesn't appear to work, at least on this particular model. Any value that triggers t...

Hi All, I have a couple of Mikrotik products as I gradually migrate my home network and lab over and so far really enjoying getting into it. One thing I have found quite frustrating about my CRS310 is the noise of the daft little fan. With a bit of 3D printing and some adapters I have reigned in the...
