The fit and finish of my beta block is fantastic. It’s better then anything ekwb I’ve had in my hands, and easily on par with the last aquacomputer gpu block I had on a 2080ti. A block which, I order in copper, without nickel plating. If your chasing that last couple of degrees, a direct to die custom loop with standard paste is going to get you more performance then lm on top of an lhs. But that’s back to that diy project.Nickel plating is not just an aesthetic feature, it actually acts as a protective layer against corrosion especially for liquid metal. Like you said, getting it right on copper is very difficult. As a customer, I expect a finished product, not a difficult DIY project.
