EK is now releasing dedicated EK Supremacy sTR4 waterblocks that are specifically designed for AMD Ryzen Threadripper processors, they are also releasing new RGB variants of their Vardar fans which come in 120mm variants. For the Supremacy sTR4 the cold plate covers the entire IHS of the AMD Ryzen Threadripper processor and the fin structure is fine-tuned for multi-die CPU cooling. The new Vardar fan also packs the Extended Range (ER) of PWM operation feature and the special Start-Stop function which brings a true 0dB experience for the absolute silent fan operation. The electronics of the new EVO 120ER RGB fan has been specially tweaked so that the fan stops spinning if the PWM signal falls below a certain duty cycle value. Not only will you be able to enjoy a totally silent PC, but this feature is also very useful for preventing radiator dust buildup in idling PCs and prolongs the life cycle of the fan itself.

The EK-Vardar RGB is a high-static pressure computer cooling fan, designed and built primarily for highest-performance computer liquid cooling systems. The Vardar family of cooling fans carries the notorious name of a type of the cold northwesterly wind blowing from the mountains down to the valleys of Macedonia. It is a type of ravine wind, enhanced by a channeling effect while blowing down through the Moravia-Vardar gap, bringing cold conditions from the north to the Thessaloniki area of Greece. Most frequent during winter, it is blowing in the rear of a depression when atmospheric pressure over eastern Europe is higher than over the Aegean Sea.
