Most annoying fan problem ever

[jcll2002]

One of my radiator fans, which ever came wit this http://www.jab-tech.com/Swiftech-Apex-Ultra-H20-220-pr-3198.html , has a really slight clicking sound. Its not plugged into the PWMIC inlet.

does anyone know how to fix this? its so annoying.

bearing noise and/or some sort of hair/lint in the motor. Pretty common problem with ball bearing fans.

spraying the fan motor with wd 40 has helped me in the past, but you may need to buy some new (not ball bearing) fans.

I find that cycling it up and down (if it has a fan controller) sometimes help. There's almost always a speed that the fan will be very quiet and not click and still move decent amounts of air.
