On October 25th 2017, I have requested for the free AM4 Ryzen cpu bracket for my Noctua NH-U14S. Noctua told me that parts were shipped by standard air mail with no tracking information, and estimate 18 working days for oversea shipping.
Now, it's 2018 and I haven't received anything yet. Sigh. I have a feeling that courier companies had stolen my item.
