Tutorial: Put custom LED's on an old fan

post #1 of 12
Thread Starter 
Hello OCN,

This tutorial from Pexx (of SweOverclockers.com) will show you how to make a jazzy LED fan out of any old fan you have lying around the house. This tutorial is very detailed and that is one of the main reasons for sharing this with you all.

Materials and tools you will need:

- A fan
- Diodes in any color
- 4 470ohms Resistors
- Cables
- Soldering iron
- Solder
- Heat Shrink (optional)
- Drill + 6mm drill
- Glue Gun (optional)
- Patience
- Coffee

Link to installing LED's from scratch without pre-drilled holes.

Right time to start, I will be using my Antec 3-speed 140mm fan.



As you can see this fan already has the holes made for 5mm LED's.



This is one of the LED's i'm using.



Fits in perfectly!



Tesing



Looks cool eh



But i can get more light out if i make the hole bigger



Better?



Green is also nice



Bend the pins to hold the LED in.



Make sure you solder the Resistor onto the positive side of the LED (the negative pin usually has a flat flange).



On with the sleeving



Cut a hole for the cables to go





Almost finished



Run the wires down the fan to the PCB



In my case the yellow wire goes to the +12v and the blue goes to the Ground. Or if you want to hook the fan up to a fan controller then its probably best to hook the 2 wires up to a molex so you get the best brightness out of the LED's. Or you can even hook the LED's up to a switch.





And the finished peice!







I am posting the rest up tomorrow because i'm off to bed! But i will be posting up a tutorial about how to make custom LED fans that dont have the pre-drilled holes.

As always leave a comment if this was helpful or will be helpful in the future, or a question. And also let me know if anything is incorrect (which i hope its not).

May i just say that i found this tutorial on another website and i have edited it.

You could always get multicolor ones with a microcontroller and have your own personal fan light show

*note If the fan is connected (or going to be connected) to a fan controller the LED's brightness will get dimmer depending on how low you have to fan voltage set to. So you may want to wire up the LED's to a molex.

If you want to connect your modded fan to a fan controller

Here is my second fan, it's an Antec 120mm translucent fan but it doesn't have the holes ready made for the LED's.



And the 3 pin connector.



And the cool temperature sensor. It changes the speed depending on heat.



Preparing to Drill the holes



The size of the LED



Size of the drill bit



How to drill



How not to drill



First drill with a small bit and make a recess so that the drill is held in place when you do the following steps.



Then drill through straight, but watch the fan blades!



1st hole drilled!





Then drill the hole with the correct size bit



And the LED fits! So now just glue it in place





First test



The same principle as before. I used heat shrink on everything to hide the wires and make it much nicer.







I decided to heat shrink all of the wire this time.







Time to wire the LED's to the fan PCB. in this case the positive is in the middle and the negative is on the left



All soldered on



Some finished pics





Let there be light



*note If the fan is connected (or going to be connected) to a fan controller the LED's brightness will get dimmer depending on how low you have to fan voltage set to. So you may want to wire up the LED's to a molex. Here are two comparisons between 12v 5v.

12v



5v



Both modded fans

Cool, glad this is going to be useful.

very legit! whats the total cost for each of the materials? is it worth converting non-led fan using this tutorial or would it just be cheaper to go with pre-made leds fans?

Sorry for the really late reply, I think it costs around £2 for 10 diodes and 10 resistors.
