Upgrading stock fans to PWM

[MusicMayne]

This is an old case but upgrading all fans to PWM should provide better airflow.

Case: Thermaltake level 10 gt snow edition

Mobo: Z170 ROG VIII Hero Alpha

 

 

So I fount 2 Noctua fans that are PWM but no luck on 200MM fans.

 

Noctua NFS12b------------------------------- 120x120x25 100 cfm (bottom intake) -----------------------------18.1db

Noctua NFp14s --------------------------------140x140x25  110cfm(top exhaust)---------------------------------19.6db

2x Cooler master megaflow red  -----------200x200x30  110 cfm(top exhaust and side intake)-------------19db

Aerocool Silent master red ------------------200x-200x20 76 cfm(front intake)----------------------------------18db

 

So my question is, are they any 200mm PWM fans out now?  These fans should make the case fairly decent?

Just so you know

 

1. PWM will not necessarily provide better air flow.

2. Fan specs provided my manufacturers are usually results in open air not inside a case.

3. There are no 200mm PWM fans probably because they are generally low speed fans.
