Running my switch fan-less

Pugsley_21 · 6th May 2007, 1:41 PM

Can i run my 16-port switch without a fan? It usually has a 5v 40mm fan, but that has died and i'm not having much luck finding a replacement. So can i run it without said fan?

you CAN, but it might keep shutting down, maybe run with the cover off or chuck a 120/80 onto it

Yeah I'd just run it with a slow as hell 120mm@5v.

I put two silent-x fans in my switch because the standard ones are way too loud

The thing is, if your switch is just sitting out on a desk or something it should be right, as the fans are there for excessively hot racks rather than open air which is significantly cooler anyway

Open it and replace the heatsinks

My modem and router all run hot enough that they are on tiles (spares from the bathroom), my dad thought they would light the desk on fire O.O, no joke, you cant touch them after a long download or when more than 3 people are using the internet! (no fans by default, probably needs them)

if a fan is installed in something it's generally needed, i'd replace it with either a better quality fan or as someone else suggested a nice big heatsink

Scotty1991 · 6th May 2007, 11:45 PM

got a spare desk fan? :P

Replace it with a normal 12v 40mm fan, it will be better than nothing.

What kind of switch is it?
I'd be checking for anything hot, and if there isn't, ignoring the fan.
If something does get hot, is it possible there's a 12v rail in there somewhere you can steal some power for a 12v fan instead?

Tried with a 12v 40mm fan and it didn't spin up until i push started it myself. Then it seemed to go alright. Can't see a 12v rail anywhere, ther power supply board is seperate to the switch board, and it has two ground and two 5v wires connecting the two. i'll try to get a photo

Whats the input power?

Might wanna try re-oiling your old fan, could still work but just be too clogged up... happens with some fans occasionally. rip off the sticker and little cover, and give it a taste of some WD40, a bit of a spin to get it all around inside, and see if she goes, may have to give it a kickstart first run.

even better soak it in wd40 over night :P
or petrol then burn it BURN
