I have been asked so many times how you paint a case fan, so I decided to chuck together a little guide to help you guys out. This will tell you how to take the fan apart without destroying it so you can paint it whatever colors you like.
First off this is the fan that I am going to paint, its a 60mm stock case fan:
The next thing to do is flip the fan over and remove any label that is stuck onto the fan. In the center you can see a white split nylon washer, you have to carefully pry it out:
Once you have done that you will be able to separate the blades from the frame:
Now you need to wash the blades in warm soapy water to remove any grease that is on the blades and carefully do the frame making sure not to get it on and of the rotor. Now mask up any bits you dont want sprayed like the back of the frame, the rotor section on the front of the frame and the inside of the blades:
Once you have masked everything up you can start spraying, make sure you spray in a well-ventilated area and follow instructions on back of can Its normally best to put a coat of primer on first but the paint I was using didnt need any primer:
I used plasti-kote metallic silver paint for the frame, remember a few thin coats is better than one thick coat. You can see in the image below I put a base coat of white on to give a good key to the top coat of paint. The blades are being painted by brush because I couldnt get the colour I wanted in a spray can:
Next I painted the blades a nice metallic purple:
I removed the masking from the frame and blades so that I could put it back together:
Putting the fan together is easy, slide rotor shaft into rotor and put the nylon water back where it came from. Use a small screwdriver to apply a bit of pressure to the nylon so it clips into place. Hey presto the finished article:
This is such an easy mod to do, anybody could do it. Now you will be able to experiment with colours and add your own effects. I painted my blades in UV reactive clear nail varnish, so It now glows a nice blue at night!
