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, the CPU block choice will impact average flow rate a lot and can thus not be ignored. In order to quantify relative performance for a CPU block thus, a normalized (% based) data set was created, with 70% weighing given to thermal performance and 30% weighing given to liquid-flow restriction. The data set created was thus plotted with the subject of this review at 100%.


As it turned out, the minor differences between the two variants of the EK-Velocity water block tested today did not matter much with them trading places in the individual tests but coming off equal here. Both end up faring better relative to the older EK-Supremacy EVO from 2014, which really needed to happen, although this is mostly because of the reduced pressure drop across the block than thermal performance. Overall, both are in the better half of the table, but get overshadowed by other blocks, both new and old.

Performance per Dollar

Prices are taken from Performance PCs 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 a manufacturer's web shop. For products no longer available, the last available reasonable price point is considered.


Things look a lot different once pricing is considered as well, with the RGB nickel/plexi version coming off much worse than the non-RGB copper/plexi version. A lot of this has to do with the fact that the RGB lighting support adds to the cost of the former and does not get accounted for as a quantified metric in this chart. Even so, we see that the copper/plexi block is not doing that much better either, as many other blocks outshine both and they barely make a dent where it counts here.
