need help on how to power a simple fan for modem - Overclock.net

banticki · 4 Weeks Ago

hi..

im pretty new to electronics (i dont know how to solder) so im rather terrified of electrocuting myself.

all i'm thinking of doing is sticking a simple cpu fan on top of an adsl modem to help cool it. i think i can manage the sitcky tape but am not sure how to power it.

i was going to use an old nokia mobile phone ac/dc converter (5-7V? i think) but i was worried about pulling apart the cord at the end fo the adapter..

are there any tips or sites i can read on basic :-
- "how not to get electrocuted or start a fire" techniques
- what kind of basic steps should i use? (eg: are the wires colour coded?)

anyway if you can point me to a simple how to site that would be good.

... But ... why?

You could get a PCI slot cooler if you really wanted to and just attach the molex connector to a PSU rail for power?

Although, I still want an answer to WHY THE HELL you want to cool your ADSL Modem. XD

that depends on what modem it is :P
i've got a 2wire hgv modem that gets pretty hot.. i've even burnt one of these before.
and for a fact, i have 2 40mm Sunons blowing into my modem, powered by an outboard psu :P

not sure about the adapter since i've yet to splice one, but for fans, red is the 12v live wire, which is the + terminal to motor. the black wire is the ground or - wire to motor. sometimes there may be a third wire thats of a bright colour, thats the speed output. u dont exactly need that since your modem wont monitor fan speeds

A Cali person knows someone from little ol' S'toon?

Saskatoon might be a small city but even I don't know everyone of the 250,000 inhabitants. This is actually the first time I've heard of that group. There are likely MANY more dancer groups here.
