    #3 This is where I would Fuck things up

      being hot from warm summers day > being hot from electrocution

      • asdasd

        You'd have to be one unlucky son of a bitch to get electrocuted by a 5V@500mA power source…
        BTW, if you have any 12V wall warts you can do the same thing and increase the speed (and noise)
        of the fan for extra cooling!!

      • Flox

        Also… why would you plug it in, while cutting it open? (If this didn't occur to you, just ignore this topic)

    • http://beerandstupidity.blogspot.com/ BeerAndStupidity

      Yep… It's pretty hard to ingore the green and white wire…

    Why not just buy a small fan?

    • der

      This is free

        But only if you have an old fan, usb cable, and a lack of any desire to set foot outside kicking around.

    • Smitty

      Hey, and there is always a chance you'd permanently F–K–P your USB ports!

      [Short out the power wires, or overload the 20ma USB power supply chip]

      Just Do It! Dell will build more PCs. 😉

    • Zrock76

      I could just buy a coaster for my coffee/tasty beverage but i prefer to use the platter from a defunct hard drive because I am a geek.

  • brandon

    Umm, not trying to be a jerk here, but I did this very thing for my Xbox 360 4 years ago to keep it running cool.
    Jus sayin……

    • Hot hot hot

      I made one of these at work with 8 fans. We work in a warehouse and our cheap boss didn't want to buy more fans so we made our own! It helps alot in this HOT miami weather!

      • Caleb

        At least Lebron will be able to go back up to Akron tomorrow night and relax in the cool air.

    • StickyWickets

      You're a jerk

    • adMANistrator

      I used a USB hub and connected my window unit a/c and refrigerator to my Apple IIe in 1985. Seriously, I did.

      • McFly

        Really a USB hub in 1985??

        You must have asked Doc Brown to bring one back to you from the future.

        • adMANistrator

          Yep. It was awesome.

      • jl1617

        Seriously Seriously?

  • Sparky_cpt

    Fan would be slow if it turns at all, that fan needs 12 volt and USB is 5 volt

    • Smitty

      Captain Sparky wins the internet for spotting the folly of this idea.

      I was reminded of this the hard way when I made a modem cooler and mixed up my 5v and 12v fans.

      • This guy

        It's better to use a small 12V power supply and install a switch from an old computer power supply. Works great

        • http://facebook.com/daaneskjold Chazz_B

          or maybe making an array of old AA batteries and an old converter to supply the 12V

          • Si1entStatic

            Or maybe a garbage powered Flux capacitor fueled by all the garbage he accumulates from those WoW power leveling sessions in his mom's basement.

          • Scotty

            Or he could just buy a small fan for his frickin' desk.

    • Frumpus

      this. of course i tried before reading this and he's absolutely right. it turns, but so slow you can count the blades.

  • DaddyD

    Easier to buy a fan that already has a USB connector.

  • Chester

    I'm sure there's no risk of this thing bursting into flames…

    • Sceptic

      Especially if you don't solder the wires together

  • Virgin man

    #7 This looks so killer! I can't wait to show all my online friends!

    • Nash

      "Online friends"…isn't that an oxymoron?

      • What an open goal

        No, it's a moron.

      • MistahBalloo

        you are quite adept at picking up on sarcasm.

    • Swiss Chalet

      You sir, made me laugh!

  • etcrr

    Try going to the dollar store and buy a cheap fan, you would be better off

  • Picard_

    Buys expensive gaming computer…can't afford proper room fan.

    • Lil John

      …or an apartment with ac…

      • usmc_chiver

        Mom's basement didn't come with it….

        • Muadieb

          My mom's basement was pretty cool throughout the year…

    • Biggus Diccus

      The fan I have on my desk at work cost me 10 bucks, I shall stick with that.

  • balticdave

    Done this with at least a dozen fans to ventilate entertainment units for friends and families…works better for that then as a personal fan…and you may want a fan grill before too long if you have it sitting out!

  • djd

    Ribi-dibi-yooooohoho! Rasta boumboum bombaclat Irie!!!!

  • djd

    Yes, that just happened

  • Ryze

    sh*t yeah league of legends

  • letter bruce

    How about…..leaving the room and going outside. It is after all a hot summer day!

    • dippy doo

      Wait, what???? Are you insinuating that someone gets up, goes outside and get their heart rate elevated past "eating a bag of cheetos, slurping down liters of cola, and jerking off stage"? What is wrong with you, man?

  • Mr X

    Because everybody has a box of old fans. Those things will eventually come in handy.

  • Smitty

    Damn brave to connect a kludge directly to the MOBO. If it works as all that is. (12v Vs. 5v and all…)

    Something goes wrong, the fan falls, whatever… it shorts and fries your computer. Big sadface when you have to replace a $1500-$2000 gaming rig because you were too cheap to shell out $10 for a table fan.

    If you want to try this folly, be smart and use the wall wart for your media player charger or phone.

    • Si1entStatic

      I've seen this elsewhere today but who calls a wall plug a wall wart. That is the first time I've ever heard it called that before. Is that a technical term somewhere. It is kinda catchy, I may start using it…..

  • jax

    thing doesnt blow hard enough, attach it to a variable transformer instead.
    That way you can ramp it up.

    Or just buy a fan


    how is my house catching on fire going to keep me cool in the Summer? because that is exactly what would happen if i tried to pull this shit off

  • Busternut

    I bought a USB powered desktop fan with LED lights for a few pounds.

  • jonnyx

    This doesn't look safe at all 🙂

    Maybe if they sold more t-shirts, they'd be able to buy a fan.

  • Scott Holman

    Stupid! Running a 12 volt fan at 5 volts will likely cause it to burn up, taking the computer with it. Yes, it will work for a while, but eventually,,,

    • Bobbbo

      Im pretty sure that Computer fans are 5v. The 120 mm fans you buy at Lowes that have only red and black are 12v

  • Jakester

    Green wire is a grounding wire, without it you could start a fire. Dumbass idea.

    • mishai

      you are bit idiot…

      5V cacles-

      USB cables(standart USB1,2)
      white… DATA –

      also 5V DC is safe ….

      before you begin argue something about US/canada cable colors…green is protective cable color instead of european green/yelow color….BUT its only for AC ……not DC….:)

      • naa

        I agree … these people talking about burning down the house etc… really they know nothing

  • imbizzle

    Hmmm… Spend $5 on a small fan, that plugs into the wall, and doesn't look afro engineered? Or start cutting, and splicing wires, and possibly burn down my house and computer?…. Think ill just hit the down button on the thermostat a couple times.

  • Are E

    Or buy a fan…
