Cryorig mini top flow CPU cooler, CPU's up to 125 watts TDP, Copper with graphene coating, Compatible with AMD-FM1 / 2 & AM2 (+) & AM3 (+) & AM4 & Intel 1200, 115x sockets
I think I still see some C7 Cu (with or without graphene coating) floating around in Taobao.
Have you searched Taobao?
BTW, if you plan to use Noctua fan on a C7, consider picking up some fan clips like:-

gotta say the cooler looks great with the noctua fan on it, havent bothered yet with swapping out my H7 for it because my new case still isnt here yet (Sentry 2.0)
They showed off new cooler recently. Damn shame if they go out of business...
EDIT: It seems they still may be active outside the USA.
EDIT 2: I found this quote from a cofounder of the company....
"Hi, this is Steve. Yes, that Steve. No CRYORIG is not out of business. I just left CRYORIG to pursuit other interests. Cooling backpacks now instead of CPUs LOL. The brand has been hard hit by the tariff wars but still operating and afloat. My decision to leave has no directly relation to this however. I have been in the PC cooling industry for 10+ yrs and it was just time for me to try out new things that interest me. I still hang out on reddit and on all my fav tech forum/sites and still drop in time to time to talk about PC's and Cooling tech. "
