Out of curiosity: how does "extremely HOT" translate into degrees Celsius?All of them are extremely HOT after 30 secs of work.
Here is my workaround solution. Temperature now managed around 50C degrees.
Wow. Well I guess it's the same here, really hot!We have the same issue with mikortik SFPONU plugged in to hex poe (RB960PGS) we are around 80° celsius

Are you still in the same situation.CRS106-1C-5S in an apartment "wiring closet" with slight ventilation, two SFPs. Both report 56 degrees C.
That's not much headroom considering during summertime it can get some 10 degrees warmer.

I wonder would SFPs run colder with individual, unmanaged media converters. I use CRS for switching only and my edge router has free ports so media converters could be used.

There are two fan connectors. I assume the two little fans als suck the air out of the router but a higher sound level.Kewl, literally, so the fan sucks air from inside the unit to the outside?
How do you power the fan?
Nice idea. That would quiet it down a bit. Did you disconnect the two fans in the back, and use the same fan header?Just want to share my chassis mod to keep my CRS317 cool and quiet with just a 140mm Noctua fan:

I CNC milled a replacement cover out from a solid plastic block. In room temperature of 30 degree C, the temperatures of 2x S+RJ10 modules (installed side by side) are kept at 75-78 degree C.
All true but not helpful when using existing Cat6 infrastructure. :)If you want to keep SFP temperature down and use 10Gbps links, then go with normal fibre SFPs and fibre patch cords. Fibre SFPs consume much less power and consequentially produce much less heat. Fibre patch cords tend to be less bulky than CAT7 cables or DAC cables which is good as it's easier to organize them and bad since it's easier to damage them (but not that easy so I'd go with fibre any time). Fibre offers better range as well ... You can get DAC cables which are essentially combibation of optical SFPs and fibre patch cord. However they offer less flexibility (e.g. if you're connecting equipment from different vendors, you can use SFP modules officially supported by each vendor ... with DAC you mostly get same SFP on both ends).
