same reason x2

I like the honest intro. There's pretty much no need for it, it's within specification. Good to see a properly done mod though.

Great project... I did enjoy the video. Got the same switch, just today!

Thank you! You'll love it. More than enough capability for a homelab by a large margin. The RJ45 path may not exactly be the most optimal, but with the SFP+ ports you have plenty of options. Haven't had a single real issue with it yet. Switching from RouterOS to SwitchOS was a little cumbersome... kept wanting to change to a non-default configuration, preventing easy access once the SwitchOS loaded. All sorted out in the end then upgraded to the latest firmware. Happy networking!

Good idea man !! Cool hardware is long lasting hardware.

Thank you, and definitely! I was a network admin on a nuclear submarine and had frequent first hand experience with failures when things get too toasty. So many components can have their life extended by reducing temps by just a few deg C. Will the transceivers ever fail regardless? Most likely not. Could they ever fail due to heat?... definitely not now!

Also works with the CRS510 (100GbE) btw :)

Only question I have is whether the heat produced messed with/melted the hot-glue. Seems like glue from a hot glue gun could get messy with how hot the cages get...

It doesn't. The fans keep the heat from sitting and heat soaking. Everything stays cool now. The plastic light guides never really got hot, just the metal SFP+ cages.

I have one of these switches and it's a problem! Especially depending on which rev. you have of the RJ10 modules...

When I first saw what you were doing I figured you were gonna hack a frame and mount the fans externally. I like that method better my only concern is is there enough holes in the case to let air in/out? Edit Commented before I watched the whole video nice mod. Be sure there is enough I have the Unifi Aggretiation Switch and it mentions something about the internal(or in your case external) power supply not having enough output to power to run all 8 even if you could cool them effectively as apparently the copper adapters pull more power.

Thank you! Honestly it will be new territory. Mikrotik only mentions running 4 due to the heat output with no mention of power limitations. The power adapter is a 22-24w unit and so far only pulled 8w with two transceivers. Haven't check the consuption with the four. Good call!

@@manofwar556 That's true! This mod allows running more than 4 S+RJ10 modules due to the heat concern when not in a PoE configuration. wiki.mikrotik.com/wiki/S%2BRJ10_general_guidance

It may be more durable to use a fan 4-pin adapter with PCB and glue the pcb directly to the inner housing where all the wires can bypass the motherboard!

I had the same problem. Bought CRS312 instead. Your solution is much cheaper.

your rack is almost empty, cut switch box and put heatsink above sfps instead of active coolers. Will consume a little more than 1u, but hey it's empty )

It's all in a different rack now along with some Poweredge servers. That was an old network switch cabinet.

? why not just add a 12-5v adapter right to the power port pins and have it all enclosed in the case

You could. That would be next layer of investment. This doesn't involve modifying the board its self and was just basic fan adapters and extenders. That would make a good second video! Thank you!

Works effectively and expands operational limits. Been in use for almost half a year now and has worked beautifully.

I had the same attitude about my switch it had 2 40mm fans in it but mounting points for 4 of them so I just had to swap out the existing fans for some noctuas and add a few more fans. then I cut a hole in the top over the Processor heatsinks and mounted a slim 80mm fan and put a fan grill over it. In the future I plan to run a custom loop watercooling setup through all my servers. And that is going to include my 10gb switch as well as my router.

Is it silent?

Zero noise. Noctua fans in general, especially these, are known for making no noise.

That's a substantial drop in temperatures and that's without modifying the Chassis. pretty cool
