Requirements for this MOD

2 Needles
Any glue cleaner or few drops of petrol
Tape
Spray paint
Cloth for cleaning and drying
A small bowl to clean the fan blades
A small box to keep tiny parts of fans ( Its imp )

 

 

Step 1: Removing the fan blades

 

 

• Remove the sticker at the back of the fan
• Get 2 needles and place em between the oval shaped gaped present on the black metal clip ( See pic one for reference )
• Now move these pins apart like you are trying to open that clip.
• When the clip is stretched apart enough the pin comes off mostly by itself as the spring between the bearings pushes it.
• It might sound a bit complex but just stretch that clip apart by placing needles in that oval portion and rest will be done by fan 
• Once you have that pin removed the blade can be pulled.
• After pulling the blade remove the bearings and the spring. Its really simple use needle to pull out bearings
• Once all the things are pulled place them in a small box like i did. These things are tiny and if lost on floor will be really hard to find.
• Repeat the steps for other fans(s).

 

Step 2: Cleaning

 

 

• Clean the sticker remnants by scraping off by nails or use some plastic thing. Dnt use metal it will scratch the plastic.
• To clean the glue left by sticker use petrol/wd-40 or any other cleaner like these having acetone in it. Even perfumes / body sprays can be used.
• After all that take a bowl, fill it with water and mix some washing detergent in it.
• Put the blades ( only ) in the solution for 2-5 min and then rotate them in there to make sure all the dirt is clean.
• Now run some fresh water over the blades and dry em.

 

Step 3: Masking for painting

 

 

• Tape the small holes at the fan top.
• I used a less wider tape and covered the fans from inside ( see pics for reference )
• Then used a wider tape to cover the whole magnet area.
• Use a blade to cut the access tape

 

 

Step 4: Painting and Results

 

• Make sure that masking is done properly.
• Spray outside use mask too as aerosol spray cans have a really bad smell.
• Shake the can well for 2-3 mins
• Maintain a distance of .7-1 foot from the object while painting
• Spray in a rhythm and keep the can moving like a car windshield wiper moves.
• Keep your layers of paint as thin as possible and rest 5-8 min after every layer.
•  
• After painting let it dry for 24 hrs and clean once with a clean cloth to remove dust.
• Assemble back ( I dnt think u will need a guide to do that now )
• Enjoy
