Noctua NF-A8 ULN, Ultra Quiet Silent Fan, 3-Pin (80mm, Brown)

I used this fan in my Tripp Lite rack mount UPS, since the fan in the unit runs 24x7. It did make the unit quieter, but not by much of a margin. Im thinking about doing something more complicated and measuring the heat on components directly, then enabling the fan until they cool down.

Just as described and shipped quickly.

Top and perfect fans! Replace all fans to the brand Noctua! Plus also installed Noctua for CUP and my raid controllers 40x10 Noctua fan is on the way of delivery! So my little tiny box will have total 6 Noctua fans!
