Thank you Alex! Thank you for a quick responce and simple straight forward answer. Putting the links made eveything a lot easier for me. I actually have 2 of those fans i want to power at the same time. Could you help me again with what i would need to accomplish that? And if not too complicated or expensive it would be awsome if i could have a temp sensor device in the mix to auto turn on and off fan when needed. Thanks again for the quick and simple straight forward answer!

You're welcome. Will you install them in a PC? If yes, then you could use a fan controller.

No it's for my entertainment center. Ps3, xbox360,and stereo is in there. The one and only shelf they are all in is open in the front but walled in everywhere else. I am looking to use the fans to blow the hot air out of the back. I have seen a splitter/y adapter on the one link page u sent under "typically bought together". But not sure if that would work for my fans. And I saw some thermal controllers on cooler guys but on the specs it has 3 pin ports/connections. Also not sure if that would work for my fans since they are 4 pin. I'm assuming my fans have 4 wires due to them having led lights in them but I'm new to all this so I really don't know. It would be cool to have the lights working but I could do without out them if need be...

"And if not too complicated or expensive it would be awsome if i could have a temp sensor device in the mix to auto turn on and off fan when needed."
For this, a power supply (something cheap, like http://www.newegg.com/Product/Product.aspx?Item=N82E16817338031) and a fan controller like http://www.newegg.com/Product/Product.aspx?Item=9SIA50M2EM2392&cm_re=pwm_fan_controller-_-9SIA50M2EM2392-_-Product

Otherwise, a splitter like http://www.newegg.com/Product/Product.aspx?Item=N82E16812718001
would do the job.

also worth noting.... its fairly easy to find wall-warts (the wall plugs with transformers built into them for say... phones) which are capable of the output v/a that you're looking for and wiring them up. i've used this a few times to power fans on the cheap but on its own its just going to be straight on/off with no adjustment.

similarly you can likely get a wall-wart to power a fan controller if you get one for the appropriate v/a required. the benefit of a power supply is that it cools itself but its also large and not so easy to hide.

they do make some smaller thermal controllers for fans if you felt like a little DIY work.

if you want simple plug and play... then as alex suggested using straight pc parts would work though would be overkill and a little ugly for the job. your choice which route you go.

be sure to put fan grill covers on your fans too in case you have children or animals.

Thank you gentleman for all the ideas and help! I ended up using a "wall wart" that was a charger for a high output flash light. 12v with 1amp. My fans are 12v .4 amp.... Originally tried the wall wart idea before I asked on here but couldn't get it to work, only the light would work but fan wouldn't spin. Turns out that fan was no good out of the box. After all your feedback I figured id open the other fan and try it before ordering some of the items Alex said would do the trick. Was too excited when other fan worked and eneded up doing a sloppy hole cut in cabinet for the fan. Just need to order some fan covers and exchange the bad fan and find another matching wall wart and I'll be set. Might order a temperature sensor or just wire up some on/off switches on each wall wart cord. Thanks again for all the straight forward answers! I'd post a pic of the fan hooked up but don't now how to on here. Hopefully this will help someone else trying to do the same thing with fans. Thanks again!
