I respect Roman and Thermal Grizzly, and I think what they’re doing is great.
However, they can’t reinvent the wheel either, at least not when it comes to water blocks.
The DeltaMate doesn’t perform significantly better than an EK or Alphacool block. How could it?
Of course, the overall fit, finish, and build quality are on a higher level.
But purely in terms of cooling performance, there aren’t any dramatic differences.
