I have been assembling PC's for over 40 years and rate Noctua highly for their excellent price point / quality ratio. Currently have two PCs with a Noctua in each. I currently would not use anthing else. They are quiet and have found I can easily lower the fan profile in BIOS without having a real impact on temps. Using this to cool an Intel I7-6700K as pictured.
This was a perfect replacement to run an AMD 8350 on Shadows of Modorf etc.as the CPU was over heating. This is an ideal replacement and even comes with its own tube of paste! It fits in the average ATX case (just).
