Hi guys!

I’m building a gaming PC for the first time and have hit a bit of a roadblock with my build with the CPU and CPU cooler.

My motherboard is a ASRock B650I lightning wifi motherboard and my cooling is a TH240 V2 ARGB sync liquid cooler (links to the manual for reference).

I followed the instructions for the cpu cooler but it’s really loose and falls off. None of the other brackets in the packet fit my motherboard. (Video of me crashing out for reference- https://imgur.com/a/CmD9Mo2 )

Is there something I’m missing or do I need to order some other parts? I’m just baffled here.

Thank you in advance, this is my first pc build and very overwhelming.
