Performance Summary

With CPU waterblocks, both thermal performance and liquid-flow restriction are important metrics. Unlike radiators where component liquid-flow restriction is not as big a factor in the loop's overall flow rate, CPU block choice will impact average flow rate a lot and thus can not be ignored. In order to quantify relative performance for a CPU block thus, a normalized percentage-based data set was created, with 70% weighting given to thermal performance and 30% weighting given to liquid-flow restriction. The data set created was thus plotted with the subject of this review at 100%.


Let's clarify that the metric for a quantitative performance summary is based on my own thoughts, as there is no universally accepted standard. As it stands, the EK-Quantum Velocity² CPU block is basically taking the lead owing to the lower pressure drop and all three EK entries share the top prize.

Performance per Dollar

Prices are taken from the manufacturer's web shop for customers in the USA when available, with all numbers reported in USD. For products not available there, the most obvious retail source is chosen, such as from a major distributor carrying the various brands. For products no longer available, the last available reasonable price point is considered.


We must note right away that aesthetics and build quality do not necessarily translate directly here, especially with intricate metal tops, RGB lighting, and integrated displays that add to the cost, but are not quantifiable as a performance metric. This is especially the case here with socket-specific blocks that include the EK-Quantum Velocity² and clearly it costs more than average given it's now slipped back down the line when it comes to offering value for money.
