I just picked up a Ryzen 1800x on Black Friday. I need to get a heatsink for it, and I have no idea what size heatsink my case supports. I got my case from a pre built computer about 3 years ago. It took a long time to figure out what case it was but I believe it to be the Arc 647 gaming case with the dimensions of
(L x W x H)
20.90 x 8.50 x 20.30 Inches
If anyone can help me find the maximum size for it that would be great thanks.
