Like just about every other product on the market, RGB has been popping up in the water cooling market for a while now. It started on Monoblocks and EK even had it on their new Velocity line of water blocks. But their Supremacy water blocks have mostly been lacking with the exception of the Threadripper block. But at CES this year they have introduced their new lineup called the Classic RGB. They characterize it as “minimalistic and clean while maintaining class-leading performance”. That explains the Classic part of the name, but the second half also indicates that the new lineup has also added RGB lighting as well. I’ve actually had most of the components in the office to check out and now that the cat is out of the bag I can share them with everyone. So today I’m going to check them out and do a little testing as well.
