Adding a fan to CRS305-1G-4S+IN

CRS305-1G-4S+IN runs somewhat hot, recently my S+RJ10 was hitting 84 degrees
Is there an easy way to solder fan pins into it?
I run it over PoE and quick poke with a probe only finds 3.3v rail, no 12v rail available I assume?

I guess if I solder into PoE rail (after transformer I guess) it should give me 48v to work with?

You’ll get whatever you’re powering the device with. Per spec it’s anything between 12V and 57V … but yes, if you power the device off a 802.3af/at PoE switch, it’ll be around 48V.
