A Closer Look At The EK-Supremacy Classic RGB
The Supremacy Classic has the looks of the older EK water blocks. However, there are subtle differences. There are no designs in the plexi that adorned the past blocks but there is an aluminum cover over the lower edge of the block. This cover hides the RGB LED strip. EK has made it so you can remove the aluminum cover and replace the RGB strip with one of your own choosing if you so desire.
The water block uses standard G1/4 ports for fittings. Each port is marked in and out. The inlet for the block is designed so the coolant hits the jet plate and is forced across the fins on the way to the exit.
What is a water block without RGB? The Supremacy is compatible with all the motherboards using a 4-pin (12+GRB) connection. The pigtail for the water block is about a foot long and should give you plenty of room to run to the RGB headers on the motherboard and if not there are 3rd party extensions that can be used.
Flipping the water block over, you’ll be presented with a large yellow caution sticker advising you to remove it before installing the water block. Under the sticker is the cold plate for the water block. The cold plate is nickel plated copper. The finish on the block is like a mirror. No machining marks were visible and the reflection of the screwdriver below is dang near perfect.
EK made the Supremacy Classic easy to tear down and clean. Simply remove the four hex screws on the bottom of the water block and pull apart. EK also included a hex key to do so. The water block consists of essentially four parts; the acrylic top, cold plate, jet plate, and mounting bracket. One of the problems I’ve had with other blocks is getting the o-ring back in place and having it stay while re-assembling. The o-ring for the Supremacy Classic can either sit on the cold plate or can sit in the groove in the acrylic top. During re-assembly, there was no movement of the o-ring.
One of the differences with the Supremacy Classic and older EKWB blocks is the plastic mount for the jet plate is no longer removable which makes assembly a bit easier. The Jet plate can only go back on one way.
