Im LOST, 12v dc power supply

[LetsDoThis]

hello all, im lost.. i got 2 120mm fans... i have no idea how i can hook them up.. i know you need a 12v dc power supply, but isnt there a couple of different ones you can get?? like a cell phone charger or you can buy one at like radio shack... which one would you guys recommend me getting (inexpensive) ... i went to radio shack and looked around they have a 12v power supply, but the thing is can i only hook one fan up to that??? would i have to by two of them?? i would like to have both of them hooked up on one if i go out and buy a power supply( if i can ) if i can buy a cheep one like a phone charger then i wouldnt mind, let me know what you think.. if you have any ideas feel free to share them, im @ a standstill & would like to move foward... anyone with any help.. i see a +Plus Rep for you...

Thank You

the fans are Rated @ 12v Started Voltage @ 6v & the rated current is 0.38A

I'm not positive but I would say you will need one for each fan. The DC adaptors I've seen only have one port but they may sell them with multiple ports. I should have been an electrician then I could wire up my whole grow room perfectly and help people more thoroughly wit electrical questions.

if you wire the fans up in series, one 12v dc power supply *should* be plenty to power two 120mm fans. check the amp rating

Yup - you could do it off one BUT it would have to have an amp rating high enough to support both. I am doing this tonight...

By the way, if you are uncertain about the fact that your computer fan has three wires and your 12 volt power supply has two here is what you do. Splice the yellow and red (switch and positive) wires together. The yellow wire is a switch which could be used to control whether the fan is on or off but in your case you will want it on all of the time. Splicing them together should make it run full time. Before you get everything set in stone just touch the wires together and make sure the fan is spinning in the right direction.

Good luck!

Both fans and ac adapters have a miliamp rating,add the fans need and get one with enough power.

when you say wire in a series, how exactly do you do that.. wouldnt you need an output to do that?

im going to take a picture of it.. there is a yellow wire as well.. but my fans had LED lights on them, they where cheap but they will work.. i spliced my old phone charger that maxed out at 9.5v and just hooked up the red and black together and it was spinning.. so i dont know if i have to do anything with the yellow wire?? my buddy said he was going to pull of a power supply out of an old computer for me.. that would do the trick... if you can post a pic of youre work... thanks man + REPPP

and my man OC finds me again, whats up kid.. so basically i would need a power supply bigger than both the fans together?

and already got my +Rep, can you will get it again

Im proly old enough to be your dad but Thanx bro.

When using less than enough voltage the fan will spin slowwer and wont last nearly as long,and if want the fan to move the air it was designed for you need the right amt. of miliamps,if using a comp. power supply make sure you use the same voltage,most have 5v and 12v IIRC.

There is a big thread here somewhere all about the comp fans and the install complete with all the wiring too,do a search bro,you will find it.
