Owned them all, they all get pretty toasty. If you're handy with a soldering iron, there's a 12V header (+V and ground) inside the case on the PCB. I soldered a 2-pin female fan header to it and ran it outside the case. Now I can attach any fan I want directly to the modem and it can be actively cooled. I use a spare Noctua low noise adapter to keep an old Cooler Master 120mm fan quiet.

Easier solution is to get yourself a 12v outlet to PC fan power brick and use that to keep the fan powered.

EDIT: Personal recommendation is the SB8200. DOCSIS 3.1, 32 downstream channels, 8 upstream channels, dual gigabit ports for link aggregation.

It comes with a 5v usb but it is a 12v fan so if you get it and want it too spin full speed just get a 12 volt to 3 pin usb or straight plug. I bought this plug for it.

I bought a few DC fan power supplies for some of these. One for the router and another for the air pump in the fish room. They work great.

One of these.

Not OP, but I have a 12V Noctua fan plugged into the wall for a fume extractor project, and I use this power supply. Plugs directly into a 4 pin PWM fan connector, no cutting or soldering required. You can probably find similar adapters for 3 pin or 5V fans. Optional, but I use a Noctua speed controller to control fan RPM, works really well.

Use this to power your pump if you want to leak test without powering the entire system.

Thanks! I am currently using this power supply, and controlling the speed manually with a noctua fan speed controller. The fan I'm using is a 4 pin PWM 12V fan. The power supply I'm using provides 12v, and I'm using a Noctua speed controller for a Noctua fan, so it is able to run at full speed. The noctua fans are pretty quiet, though this could be used with any 120mm fan, so it'll vary depending on the chosen fan. I'm using a static pressure fan, so the airspeed drops off pretty quickly with distance from the fan, but I'm planning to use this within an essentially airtight enclosure, so this slow moving airflow should avoid creating drafts in the enclosure while filtering the smells/particles out of the enclosure air volume over time.

It should be noted that I haven't finished building an enclosure yet, so I don't have any tests of how well it'll clean an enclosure yet, but that's the theory on why I'm using a static pressure fan.

Of course. You can buy a 3/4 pin fan to DC adapter like this: https://www.amazon.com/dp/B084JG4619/

There are also 3/4 pin fan to usb adapters like this but the fan will only run at around 40% of max speed due to usb being 5v. https://www.amazon.com/3-Pin-Sleeved-Adapter-Connector-USB-3Pin/dp/B07JW73KVR

Instructions- I just used CA glue to attach all 4 pieces. You can weld it if you want. For the control box here are the steps I did- do this at your own risk:

I removed the bottom panel, pulled out the power supply (left the wiring in place)

Removed the panel from the power supply, unscrewed the fan and unplugged it. Be careful and some components on the power supply board are still holding a charge.

I drilled some extra holes in the power supply panel.

Next, for the controller fans, there are two. Both plug into your main board. Simply unplug them and unscrew the fans and remove. The rear fan can be difficult to get to, and made me unscrew the main board. I did not unplug anything for this, just moved it out of the way.

Once everything is removed, reattach the powersupply panel, and screw the power supply back in.

For the print, I put in two 120 mm pc case fans. I bought this to power them- https://www.amazon.com/dp/B084JG4619?psc=1&ref=ppx_yo2_dt_b_product_details

Use a self tapping fan screw and fasten the fans from the underside. I have both fans blowing up. Once that is all set, place the control box on top of it. I left the bottom panel off the control box to increase air flow. The reason I didn't leave the power supply panel off is to protect the components and the panel also provides grounding.

You could also just by a dc power adaptor and plug it in directly.

Purchased these. Instead of using a splitter, I run 1 power supply per fan.

That's what I did. Dug an A12 out of my closet and plugged it into this.

I bought this it's running 3 PC fans no problem. Probably would be able to connect 2 more if needed.

From the page you linked, a wall wart with 3 pin connector, made by Coolerguys, that will power this fan.

Runs off of 110-240v AC. Probably the easiest way of doing this.

I just bought this to power my D5 pump
