[SOLVED] Please help me choose a noctua case fan

[TechGuy75]

I plan to replace the front 2 140mm case fans on my define r4 with 2 140mm case fans. I am planning on doing noctua fans.

Whats the difference between these 3 fans, which situations are they used for?

NF-A14 PWM vs. NF-A14 5V PWM vs. NF-A14 5V

They are all 1500rpm max

The 5V models are made specifically for 5v power sources. You don't want those. The regular NF-A14 PWM is 12v. Which is compatible with the general Motherboard fan header.

Thank you. That answers my question.
