[Router Mod] 80mm fan on my Netgear WNDR3700

post #1 of 8
Thread Starter 
So I previously modded my Cable Modem to add an 80mm fan to it, and decided to do the exact same thing to my wireless router. It's a Netgear WNDR3700, running DD-WRT...and it only functions as a Access Point (I run Untangle for my firewall). The fan is the other rear 80mm fan that was in my Norco RPC-4224 chassis.

Like the modem, it's a little noisy to be sitting on my desk, but that's only temporary. Once I finish up my mDC, it will be mounted on the wall in a 8' x 8' room with my servers and other network equipment, out of sight out of mind.

Inside of the router, with the top behind, and various plastic pieces.

Inside of the router, from a different angle.

Close up of the PCB board. The black square that says CHDS is the heatsink on the main chip. Beside it is a small heatsink for some other chip, and the big L shaped silver thing is the wireless antennas (I'm guessing).

Screw holes drilled and fan mounted to the top case.

My solder job, on the DC jack. I was going to solder the fan to the switch, but the pins on the switch are too close for my comfort, and I would probably have messed it up. So if it's plugged up and the switch is off, the fan is on but the router is not. I never use the switch anyway.

Further back shot of my solder job, plus the top case with the "round" hole cut for the air flow.

Fan mounted, router reassembled. Job complete!

Let me know what you think!

Isn't it kinda pointless? I mean, routers are obviously designed to run 24/7 for years, do they really need extra cooling modded in? Looks cool though. smile.gif

I don't know if I would call it completely pointless, as heat is the enemy to any and all electronics. What happens to a 3 year old laptop, even rebuilt with a fresh OS? It is slower than the day you got it. Why? Heat effects on the hardware.

I'm sure routers are designed to run at a certain temperature, in a certain ambiant temperature room. My home office is currently the warmest room in my house (around 76-78 degress), while the rest of the house remains 68-70 degrees. My office is so much warmer since I run 3 servers, 2 desktops, 2 switches, router, modem, wireless printer, and a laptop...which all generate heat. The fan does noticably cool the router, just as the fan on my modem cools the modem. I wish I would have tested, but theoretically, the performance of my router shouldn't have increased, but it should have maintained how it runs when it first starts up, before a weeks worth of heat is floating around in the case. That heat could have caused a decreased range in the wireless signal, by reducing the Tx power, and the onboard switch could have also dropped packets from the heated chip.

Food for thought.

Those little netgear routers do get pretty hot, i've always wanted to wire in a fan to a router. Our verizon fios router used to crap out all the time so I stuck a desk fan clipped above it and the router has been far more stable since.

will be nice to add some fresh air to the hot part...

but you should juice the fan out with another PSU me think wink.gif

Yes, it's really nice to circulate the air. Circulate enough that you can tell an extreme difference of the chips on the PCB board, and that I feel my wireless signal is working better (not further away, but more stable). I also thought about using an external PSU, but decided against it since it would look ugly, haha. Seems that the DC jack that came with the router is providing adequate power to everything. Same goes for my modem, which is also super stable (power wise), can feel absolutely no heat at all from anything outside or inside the case, and has been performing great over the past two weeks.

you may want to consider switching that to an exhaust fan, it will get a massive dust buildup within the router over time. Of course you can pop it open and dust it out but I would think routers don't handle dust build ups as well as normal PC components do/don't lol. If not then maybe slap a little filter over that fan to avoid the dust build up.

A filter is a great idea. I will definitely add one in between the fan and the fan guard.
