Many of the CPU Coolers requires you to remove the motherboard's original CPU brackets and install the new CPU Cooler brackets if the motherboard doesn't come with the correct type of brackets.
I have an AM3+ Motherboard that came with the old style Level bracket to hold down the CPU Cooler. When I purchased a CoolerMaster Hyper 212 EVO I needed to remove the Level bracket and install the CoolerMaster CPU Cooler bracket (The bracket uses four screws) to be able to install the new CPU Cooler.
If you motherboard doesn't come with the correct CPU Cooler bracket for your Wraith, than you need to replace the brackets with the Wraith CPU cooler brackets to be able to install it.
I imagine if your Motherboard is a AM4 motherboard it should have the proper brackets or screw holes for the Wraith CPU Cooler to be able to install.
You may need to remove the brackets and install the Wraith Brackets if it comes with it. from your motherboard's Support:
