Glad I found this thread.. When I looked on CM's site this past Wednesday, the specs for the MasterLiquid Pro 240 did NOT have the asterisk after the AM4 compatibility.. So that is what I bought. Now I find out it's not compatible, and that the bracket is "coming soon.." feh Not that I'd be able to order the part since they want me to register the product first. That would be fine if the thing HAD a serial number on it. Yes I bought it new, it arrived heat-shrunk and there were absolutely no signs the box was ever opened and cooler ever removed. This blows my plans to finally complete my Ryzen build over the weekend. I'll wait to see what response I get to my support and FB inquiries, but I have a feeling come Monday I will be returning this for another maker's product that IS AM4 ready now and not some unspecified future date.
