Why dont you click on that great link about computer fan wiring in the DIY section of this forum above?

Or you could google your question and maybe find the answer there.

Good luck.

You can buy a 120mm, 120v PC fan at Radioshack. It will plug straight into a normal wall socket. Or, by 12v fans from where ever and use an AC adapter to power them (also available at radioshack)--like this:



A 1.5amp adapter should power a number of fans depending on how many amps they draw.

would it cary to much power to the fan causing it to burn up just courious and how many could i hook on to one plug set up or how many watts or amps iam not really sure iam not the smartest person when it comes to things like that ...so thanks

You just need to match the volts of the AC adapter to the volts of the fan. 12v fan uses a 12v adapter. The amps outputted by the adapter can be greater than the amps drawn by the fan. A 0.25 amp fan is fine hooked up to a 1.5amp adapter. Just don't try and pull more amps than the adapter provides.

--Keep the volts the same.
--Keep the amps of the fan below the amps of the adapter.

Example: Radioshack sells a 120mm 12v 0.32amp fan (but you can get similar fans for less from anywhere that sells computer parts--e.g. TigerDirect.com). One of them will connect just fine to the 12v 1.5amp adapter pictured above. Also, you could connect up to four of them to the same 1.5amp adapter since you'd still be under 1.5amps (0.32 x 4 = 1.2). It's best to stay a little under the amp rating of the adapter. My understanding is you may stress the adapter if you try and pull it's full amperage continuously.

For the above scenario, wire the multiple fans in parallel (vs. series) so each fan receives the full 12v. If you wire them in series, the voltage will be split between the fans (6v each) and they'll run at approximately half speed (or not at all if they're sensitive to voltage input).

I'm told it's always best to use identical fans when wiring multiple PC fans to the same power source.

DUDE YOU LOST ME so please explain it to me a littler stupider cuse that is to much smartnes for me thanks...and iam not beimg rood

Try doing some research with Google on the difference between wiring in parallel and wiring in series. Hell, if you look hard enough you can probably find a DIY tutorial specifically for wiring PC fans (search on this and other marijuana growing forums). ;-)

Here's an example of series vs. parallel:




Instead of an amp you'll have a power adapter. Instead of speakers you'll have fans. In parallel wiring the positive wires from each fan would all be connected together to the positive wire from the power adapter. Same with the negative wires. Parallel wiring is easier, so that's good.

If that's not enough to go on then you might consider getting first hand help, doing a LOT more research, or just using 120v fans that plug straight into the wall. PC fans aren't high powered items but there's still some danger of overheating something and causing a fire if you screw something up badly enough.

Good luck.
