NoctuaNF-A14 PWM, Premium Quiet Fan, 4-Pin (140mm, Brown)

NoctuaNF-A14 PWM, Premium Quiet Fan, 4-Pin (140mm, Brown)

Q: Is this a regular box fan

I'm a regular boxing fan. I like MMA too.

Q: Has anyone experienced a clicking motor noise caused by PWM ?

It is because you have it hooked up to a 3 pin source. PWM, 4 pin fans, run at 12 volts all the time. The fourth cable is what controls the speed. 3 pin fans use variable voltage to control RPMs. You need to use a 4 pin source or run it at full speed, 12 volts, or you will always have clicking.

Q: can i used this fan to my corsair h110i that have factory fan

I have 4 of the 120mm fans in my h100i, I cannot imagine why the 140mm fans would not work in the h110i, you just have to use the screws corsair provided you. I will say though that you will be very surprised by just how quite these fans are while providing the same cooling performance as the stock Corsair fans.

Q: Would like to get 2 intake front fans. Would like to know which would be better for airflow these or NF-A14 FLX. Thanks!

They are essentially the same fan the NF-A14 PWM and the NF-A14 FLX. The difference is that the PWM can be controlled by software on your system through your motherboards resources. Most modern motherboards have the 4 pin connector and support. The NF-A14 FLX is controlled by adapters that are included in the kit. There are usually 3 adapters. They controller the air flow on the FLX model. I have used both and I usually prefer the PWM model because I can set thresholds in my system when temps get hot and can cool my system down faster automatically.
