Im not sure this has been posted anywhere. I hope this can ease the air cooling user on cleaning their fans. I have almost 6 casing fans that on 24/7 , 2 of them is transparent color fan and 1 is Cooler master Aero 7+. These fans are super dirty and the dirt almost cover the color on the fan..Cleaning them is not easy especially the Aero 7+ as the fins are ridiculous small and unable to reach by cloth...

Thus, i came  of an idea and i've tested it during chinese new year. Just 3 steps can clean ur computer fans just like new.

1. Prepare a baldi of water, pour the dish cleaner liquid inside the baldi. I pour about 1 ml dish cleaner.

*The step may be risky. STOP here if u dun wan to take the risk. 3 of my tested fans cost about Rm 200 last time, but still i have confident it will work.

2. Dip the fans inside the baldi. I left the cable out, just my fans are in the water with dish cleaner.

*AFAIK, dishcleaner can clean away oil easily. I dip the fans about 10 hours as i perform it at mindnight.

3. Take out the fans and wipe with dry cloth, leave it dry for few days.

* It was a surprise when i saw the fans are so clean. previously, i unable to clean the dirt on the fans using cloth, and some edge that unable to clena. I have leave the fans dry for 2 days.

All the fans are in working condition after i confirm  it is 100% dry. Now my fans are like new, my cooler master green color fan speed has increase back from 2300 to 2500rpm. All the dirt inside the bearing has been clean, the fins are shiny..
Notice the fins of Cooler master aero 7, as i use it as a casing fan, the fins are very dirty, previously it was black color...Because i unable to reach the fin using cloth.
