DIY LED Computer Cooling Fan – For Light Up Computer Case

LED Case Cooling Fans are a good deal of nice looking clear PC cases in any type. And you can replace those fans with ordinary fans without any problem. So I went to upgrade my ordinary PC into cooler PC and then I find out good quality LED fans are quite expensive and lower price fans are not quality enough. So I decide to make my own LED fans and see how hard it can be.


First, I thought use handmade LED arrays for the lightning, but then I decide to use ready-made LED strips which is more suitable and very easy to work with. And you have to go with bigger cooling fan, because they have bigger space between the fans and housing than smaller once. Or you have to cut some fan blades to make enough space to put LED between them.

So here is the list I needed for the job.


1. LED strip (12V is better, make sure they can cut in the middle)
2. 120mm Regular cooling fan (Transparent ones are better)
3. Some white/ silver paint (If you couldn’t find a transparent fan)
4. Wires, Soldering iron, Glue or Double tape (you might want to check LED strip with that)
5. Paper cutter

Step 1
Dissemble cooling fan by removing the fan from its housing. Usually in the middle of back side you can find the lock for the axis. Removing it by safely you can remove the fan blade along with the magnet. Some of the fans are sealed and you may want to use some force to break, but if it’s sealed try to do the next step by skipping this.


Step 2
Measure the outer diameter of fan cover and cut the LED strip. Some strips contain transparent rubber cover for its looks and protection. You can remove it carefully to make LED strip more thin.

Step 3
Attach required wire to strip by soldering and attach LED strip into the fan housing as you planned. It’s better to use the thinnest wire you could find. Or use some coil instead.


Step 4
Check for any conflicts between fan blades and LED’s. If needed, use a paper cutter to peel off some material from the blades. when do that, make sure all the blades are getting the same amount of cuts or otherwise unbalanced load will be make vibration when the fan is rotating.


Step 5
Connect LED strip to power. If you use 12V LED strip and 12V cooling fan you can simply connect together with correct terminal. Or you may need to have different power sources to power them up.
After finishing this, I replaced my power supply fan with this and find out my power supply use 5V to power up the fan in initial state and only use 12V when the system generate more heat. So I had to connect separate 12V power to lighting LED strip. You can always get 12V from directly from PC power supply.

If you are not using a transparent fan, you should apply some paint over the blades. It will add a nice effect to the fan. And that’s it. Enjoy the new look of your PC.
