The CPU cooler isn't compatible with your motherboard.
The CPU cooler isn't compatible with your motherboard.
I received the build from the PC Partpicker guides. It indicates compatibility, but when you attempt to install the motherboard mount on the back, it appears too short or only fits on one side. You mentioned this is your first PC build—your DeepCool AK620 CPU cooler and Gigabyte Z790 D DDR4 ATX LGA1700 board. Here’s the link to the guide: https://pcpartpicker.com/guide/z3G323/ma...ming-build. This might be a setup issue.
