Does Noctua NF-F12 PWM have the annoying motor ticking noise like other pwm fans?!

because I want to replace my cm 212+ blademaster fan which has this unbearable ticking/clicking noise.

A motor ticking noise is not a feature of PWM fans which are normally very quiet. I would think either your fan is bad or you may have a loose wire making contact with the fan blades... if no wires are close enough to make contact with the fan, replacing the fan (with most any PWM fan) should take care of the ticking noise.

I'm sure there is no wires touching the blades but from my google search I found this motor ticking/clicking issue is common especially at low rpm and it happens with a lot of pwm fans from different companies.
I found that link at Noctua site http://www.noctua.at/main.php?show=ne_fd1_pwm_ic

I just want before ordering this fan to be sure that it doesn't have the ticking issue.

Most PWM fan exhibit some level of clicking and some even whines at different duty cycles.

Alot of the time it doesn't matter much because the fan is housed inside a case that dampens the noise to a point the user can't hear it. However, some people will build their computer to be a silent machine and/or work in very quiet environment. The noise produced by PWM fans will be much more noticeable.

I am very picky with noise and clicking/whining annoy me immensely. I've tried numerous PWM fan. Some of them click loudly. Majority of them click quietly or mildly and a few will exhibit high pitch whines.

The only fan that I have heard "ZERO" clicking or whining noise are Noctua PWM fans. They are dead silent. Seems like noctua has their own special pwm circuit that specialize in eliminating those clicks/ticks.

Thanks for your replay.I already purchased the fan and it has zero clicking noise.
