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

Bought these for a specific case mod where I needed to dissipate heat from a gaming PC that was mounted in a confined drawer under the ceiling. I installed two of them side by side on what used to be the front of the PC and I can tell you that there were no problems with these fans, they solved my cooling problems. At first I thought I needed some 120mm fans blowing INSIDE the case and these two fans blowing out of the case to provide the airflow needed to cool the 1070 TI and I7-3770 when benchmarking . With this push-pull setup, I found that the CFM boost of one of these fans matched almost 4 of my other 120mm fans. So what will happen is that 120mm fans will be sucked in faster than they normally spin, resulting in excessive fan noise. After removing all 120mm fans and blowing air through the PC, all 120mm fan noise is gone and cooling is at maximum. Oh yeah! Another time I will post a photo of my mod.
