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

I bought two of these to put in my Thermaltake Suppressor F1 case to suck air out of the back of the case. I only had one 4-pin motherboard connector available, so I also bought a Noctua NA-SYC2 3-pin Y-cable to connect both to that connector. They're so quiet I can't hear them at all, and I can control their speed from my ASUS Z170i Pro gaming motherboard. A low noise adapter cable was also included with the fans, which I tried, but the fans are so quiet even at maximum speed that I don't use them. Odd color aside, these fans are almost perfect.
