Router Cooling Mod

Recommended Posts

So I bought this WRT310N a couple years ago. It's always been flaky, but I paid too much for it and I can't bring myself to get something different. It has always flaked out during periods of high load - torrenting and multiple simultaneous users always brought the wireless network to a standstill and caused dropped connections. Various manufacturer and 3rd party firmwares made no difference. Probably overheating, amirite?

 

I always meant to do something about it, but I have a habit of living in a dream world when I "mean to do things", so I never did. My goal this year has been to . or get off the pot.

 

After acquiring a free backup router in case of failure, I ripped the the WRT310N open. One tiny little heatsink on the switch, nothing on the CPU or wireless radio. Touching the heatsink was painful it was so hot, and the CPU was just as gnarly. The wireless radio chip was just warm. I chopped up an old Northbridge heatsink I had kicking around, and stuck them on the switch/CPU chips with some random Coolermaster paste and a little drop of superglue in the corners. I left the cover off, with a 80mm fan was used to blow air over the bare board. After a month of uptime and rock solid stability, I considered it a complete win.

 

Then I hacked up the case to make the cooling solution permanent. Pressure fit a quiet 40mm fan, soldered it to the board, and opened up holes for the heatsinks to poke through. Heatsinks are stay cool to the touch (They'd get quite warm without active airflow!). It ain't pretty, but it works. I love it. I'm so stoked.

i have the WRT54G2, the moment i saw your mod made me think why not give it a try with my router :rolleyes:

 

these "little guys" is the only thing i cant think of for now to have my "improvised heatsinks", not bad with the clearance from the top covered back.

if too lazy to hunt for those 60mm fan, i'll just drill tons of holes with the top cover instead. :biggrin:

I wonder if you can get away with a naked router?

At my old job we got our own wifi without monitoring by using a bare WRT54G board with the antenna and the power cord plugged directly in to it. It worked without issues the whole time I was there :)

hmmm... good enough i believe, the cover now seems cold to touch even after hours running :thumbsup:

and i think those staples quite helped either.. having much more surface area now, better then bare chips imo ;)

 

 

to run my router bare/ board exposed was also what i thought in the first place but dust will be my problem i guess.
