1. We have been building PCs for 25+ years and improvements have been made consistently. The new Supremacy for example had better thermal peformance than the old one. Whereas back in the day it captured the CPU cooling title only on some CPUs sockets, other brand blocks did better with others. The current one, took the title across the board.
Like CPU generations, these go thru periods of marginal improvement but w/ water blocks, performance has improved slightly generation to generation and usability do improvements occur.... things I'd like to see:
a) Better cable connection options, accommodated by the blocks.
b) Feedback control of pump / radiator fan speed
c) GPU, VRM, Memory, Coolant temp outputs to digital displays like the Reeven Six Eyes, the backpate, terminal block or a software utility
d) More MoBo Mono Block options
e) Better dual card terminal block connectivity options
2. I see no real purpose for a "universal" GPU block that does half the job and leaves VRMS and memory uncooled. Might as well get a hybrid or CLC. However VGA Universal Blocks have existed since the birth of EK.
