What are the differences between the cuplex kryos NEXT VARIO with VISION 1200/1156/1155/1151/1150, PVD / .925 silver €314.90 and, cuplex kryos NEXT with VISION 1200/1156/1155/1151/1150, PVD / .925 silver €284.90?

Before I make my selection, I would like to know the advantage of the €315 water block. And, how much of an advantage can I expect from a silver cpu water block vs the nickel?

Thank you.

Thank you! I am not familiar with the “Vario“ design, in any event, I’ll try and get some of the literature translated and read up on it.

Section 5 in the MANUAL discusses how to afjust the VARIO model.

Thank you for the very informative links, apparently the larger surface area that the micro fins cover may add to the flow resistance factor, but with interesting results. Would the selection of pump be critical to counter the flow resistance and type of fluid used, so as not to clog the micro fin layout? I understand that the fins are staggered with regular breaks, instead of long continuous rows of micro fins, which does allow for better flow.

What I failed to mention was that, unfortunately, the reviews did not test for the effectiveness of the vario custom adjustment option, as it would be interesting to sample the real world application of the cold plate “mating” option. Incidentally, how would one gage the ideal maximum surface area contact, cold plate and IHS?

There is one review in German: https://www.computerbase.de/2017-03/cupl…ben_ohne_effekt They reached an improvement of only 0,1 K.

Very interesting review, Thank you for sharing. Although the Aqua Computer Cuplex Kryos NEXT and Alphacool Eisblock XPX received the highest accolades for temperature control/performance; the VARIO cold plate adjustment feature was not effective in improving on the factory calibration.

Apparently, the manual adjustments for the base plate curvature only managed to improve on the factory calibrated setting by -0.1 Kelvin and reversing the adjustments degraded the performance of the “Cuplex Kryos NEXT” increasing the operating temperature by as much as 0.7 Kelvin, temperature difference between the water and the warmest CPU core.

The performance testing was compared to 5 other cpu water blocks, currently available on the market. The reviewer also added that the thermal paste, radiator, enclosure ventilation and radiator cooling fans were more critical considerations than the VARIO adjustments.
