CPU-COOLER

Just another human being :D

Check out this cool CPU-cooler!!! Its mostly made up from useless-computer parts and its very cheap and effective! I have used the principle in which a Jet engine works. One fan is sucking in, and the other works as a exhaust fan. To check the quality I have used it on my own laptop for 7 hours continuously, and even after that, the laptop didn't heat up at all! Its a great way to reuse electronic waste products and build something useful.I use it mostly during long hours of movie-downloading!

Things I've used:

1. A smps I got from the computer shop garbage

2. A vintage- AMD processor fan(with the radiator) I got from a computer workshop.

3. Iron wires(for attaching the fans and radiator)

4. Exhausted refills(pen refills)

5. Two LEDs

6. Wires

7. Resistors

8. A usb cable I got from a damaged PC-mouse.

9. Soldering kit

10. Tape

11. A 12 V adapter

Step 1: Attach the Fans With the Radiator

Attach both the fans with the radiator with iron wire. Use the screw holes on the fans for better support while attaching the fans. I have used pen-refills to seal the fixing(as you can see in the image). You can attach the fans in any way you like but make sure that it doesn't create obstruction to the fans.

NOTE: The stickers on the fans should face opposite directions.

Step 2: Connect the Fan-wires

After attaching the fans with the radiators, connect the fan wires in such a way that the small fan sucks air in, and the bigger fan acts as a exhaust system. To do this, first check the air flow of the individual fans by attaching them to a power source. The motive is to use the principle in which a jet-engine works.

Step 3: Attaching LEDs for a COOL-look!

I have used two multi-color LEDs for this purpose. I have connected the LEDs with the USB-cable so that the Leds are powered by the computer itself.

CAUTION: The USB connection is of 5Vs. I need 3Vs for my LEDs. So, I have used two resistors to reduce the supply.

Once you have connected the LEDs properly, insert the LEDs in the middle gap of the radiator.

Step 4: Power Supply

You'll need a 12V adapter for powering the fans.Remember that both the fans will be connected to the same adapter. The LEDs will be powered by the USB connection. So now, just plug in and enjoy!

    Is it possible to mount it on a desktop CPU?

    Interesting idea. The heat sink is cool but probably not doing much. The purpose of the heat sink is to distribute the heat from the CPU so that there is more surface area to radiate the heat away into the air. The fans help with convection of the air though. As long as the heat sink isn't touching the CPU it's not doing much.

    Ummm... I'm not sure if the thing you have done is done correctly... Especially with LEDs and resistors. What value resistors you have used? And how everything is connectes? Because nothing here looks clear.

    The LEDs are well insulated from the aluminium block by insulating tape....the LEDS are connected in parallel....and the resistors are also connected in parallel...if I would have connected the resistors in series, the resistance would be large....the LEDs won't light up....

    But could you draw the schematics of your connections? because I still don't understand everything... Resistors are in series to leds, or in paralell?

    Yes, many errors... resistors in parallel...the connection of the leds, the aluminum block... sorry for mi bad english ;)

    You aren't doing a thing for the heat with that heatsink. It's no more than a brick to connect your fans to here. A single fan will remove as much heat as an intake and exhaust. It would be smaller, quieter, take less energy, and less space. On the upside, it doesn't hurt a thing to make it the way you did and it isn't dangerous!

    small change in resistor values, and you could run the LEDs off of your 12 volt fan Supply also. Save the hassle of hooking up the usb cable ( maybe use a switch to let you turn off the light but leave the fans on )

    nice project but why would you need the heatsink when you are just get out the air from the cpu you arnt conecting that to a real cpu !

    No, but when you are going to use it for long hours, you are going to need a heat sink....After 5-6 hours of usage, laptops heat up to be pretty hot! At that time a heat sink is required!
