Review on Noctua NF-A20 PWM chromax.Black.swap, 🖤 Premium Silent Fan, 4-Pin (200x30mm, Black) by William Santos

I bought this fan to replace a failed Cooler Master A20030-10CB fan that was installed on top of the Cooler Master HAF 922 case does not allow installation in this particular one Case using a 154mm hole spacing. I wasn't aware of this before I bought the fan. However, there's nothing a few marks and a quick dremel can't solve! Now that the fan is in the case I love it. Virtually silent and moves a lot of air. Huge improvement over the fan I removed even though it was 8 years old. Let's see how this holds up.
