Affordable 10Gb Networking for the Home! - MikroTik CRS309 - • Affordable 10Gb Networ...
In this video we'll be taking a MikroTik CRS309-1G-8S+ and modding it by adding Noctua fans to it to assist with cooling. A nice feature of the MikroTik CRS309 is that it is a fanless switch which is perfect for most situations in a HomeLab network. What can be bad is if you are using multiple RJ45 SFP+ transceivers, the transceivers can get very hot while the switch CPU stays cool. Typical fiber optic SFP+ transceivers stay cool, but not S+RJ10 transceivers used with copper ethernet cables. 10 gigabit ethernet networking can make your home network much faster, but you need to be aware of the options available.
Using 5V Noctua fans NF-A4x10 we'll be able to place them directly on top of the transceivers, reducing the temperature well under their rated temp and possibly extending their life. MikroTik does not recommend running RJ45 transceivers side by side, rather keeping them spaced apart. This unfortunately turns the 8 port SFP+ switch into a 4 port 10Gbe switch. Adding fans will allow using all ports for 10 gigabit RJ45 networking. The 40mm Noctua fans have a rated airflow of 4.83 CFM with a static pressure of 1.78 mm/H2O. They are also very quiet at only 17.9dB. The Noctua fans will be powered from a 5V USB port on a power strip that's plugged into the server rack UPS battery backup, so in case of a power outage the fans will continue to cool the switch. - วิทยาศาสตร์และเทคโนโลยี
"why? becouse i can and i cant leave things alone " same here .
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.
Some proper hot glue gut stuff here XD
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 :)
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.
Its worked very well so far! 6x SFP+ RJ45 modules side by side for almost a year now with zero issues and cool temps.
@@Warning56kb Good to know. I still have two CRS309, but decided to not use RJ45 modules anymore due to high power consumption. DAC seems to be the winner here whenever you have a choice.
@@hit-757 Well said! Especially if routing through tight spaces isn't an issue, DAC is the way to go.
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!
@@Warning56kb CSS/CRS309-1G-8S+ -- 8x S+RJ10 are supported if PoE-in Voltage >30V. Up 4x S+RJ10 are supported when PoE-in Voltage = 24V. That is what the manual says.
@@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.

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

Works effectively and expands operational limits. Been in use for almost half a year now and has worked beautifully.
That's a substantial drop in temperatures and that's without modifying the Chassis. pretty cool
Is it silent?
Zero noise. Noctua fans in general, especially these, are known for making no noise.
