Review on Noctua NF-A8 ULN: 80mm Silent Fan for Ultimate Quietness - 3-Pin, Brown by David Batte

Let me quote myself from my review of a unit that has used this fan because it speaks for itself: First, let me confirm that the excessive noise reported by other buyers is REAL. The original 80mm fan with RGB LEDs (model QSCD 8025S) is VERY loud. So I did myself a long-term favor and replaced it with a high quality Noctua NF-A8 ULN fan. Day and night! The noise is gone. I've also left out the original fan's fancy RGB lighting, but the position of my case isn't visible, and what a difference!
