EK Supremacy EVO Clean CSQ CPU Water Block Review

Final Thoughts


EKWB and their Supremacy EVO prove once again that they are more than capable of some of the best performance offered in water cooling. The Supremacy EVO looks much better with the revised Clear CSQ design. We can't say we can recall any one specific block that is, or was offered in thirteen different configurations of plating, Plexi color choice, and Acetal tops, and of course, various options with or without nickel plating. So, while we did test the more vanilla version, there are plenty of options to choose from to help keep a seamless lighting or color scheme throughout your system as you add this new block.


Everything about this block is done in typical EKWB fashion. EKWB offers all the hardware needed for most users out there, and even for ILM needs upon request; they even offer the optional mounting plate. When it comes to the design, offering various inserts and jet plates to maximize its effectiveness is also something not everyone does; most companies just send them as-is, and you get what you get. The mating surface is done well, and is finely polished and clean right out of the box. As far as mounting it to the board, while the backplate took some time to screw into place, the rest of the installation was a snap, and the thumb nuts are very easy to use. Even when it comes down to filling and bleeding the loop, with all of the tight spaces, it was ready to go with only about 10 minutes of bleed time. Of course, we ran it longer to verify against any leaks, and we had none.


The rest of the kit EKWB sent along is the reason this block is able to perform as well as it does, but let's scrutinize those bits shall we. The radiator we received is thin, much thinner than others on the chart currently, and it also comes with a high FPI arrangement of its fins. This does not tend to offer the best results, and really is dependent on the fans. Even here we just grabbed what was handy, and while we used nice fans, they are not spectacular by any means, and we still managed to produce these great results. Then, when it comes to the pump/res combo, we only used a 100mL reservoir, and with such a short run of tubing, there is not much coolant in the loop to saturate. Even with all these factors stacked against the EK Supremacy EVO, it took the third spot; that is a true sign of its quality and efficiency.


For the guys just starting out: yes, you will need more than the near $80 invested in this block to get by. However, for those already in the water cooling game, to just replace the CPU block, this EKWB falls right into the average cost range. We really do appreciate the new look, while keeping that cool logo on all of the components. Also, while the box alluded to a nickel-plated version, we have no issues with the copper/Plexi version for two reasons.


First, once installed and running with pastel white coolant in the loop, there is no copper to see any more if we did have some strong dislike for it. The second reason is: if we can save $5 off by purchasing the copper instead of the nickel, why not jump at that opportunity? Because we were able to get stellar performance with the odds plainly against our CPU block, there is no way in good conscience that we cannot strongly recommend one of the many versions available of the EK Supremacy EVO for your next loop.
