## Customer Reviews

### ⭐⭐⭐⭐⭐ of byski quality expected
*by D***A on August 5, 2023*

This was acquired for an ASUS TUF B670E. I was surprised by its large sized and concerned that it might not fit. Installing, I found that ASUS uses 6-32 screws for the onboard CPU backplane. The Bykski was shipped with M3 screws. Its odd that ASUS used a non-metric thread. I went to the hardware store for appropriately lengthed 6-32 socket head screws; found some that are stainless steel that set me back $4. They look nice enough.On install I found that it cleared the ASUS nvme pcie5 heatsink by 0.5mm. An aftermarket nvme heatsink could possibly be a fitment problem.Overall, its a stellar looking CPU block with a super large micro-fin section that keeps temps very low and I am happy to have it in my build.
