The Swiftech Drive HD kit sat at the top of the charts so long that I wasn't sure I was going to find a cooling system sold retail that would beat those results. EKWB has done just that with brute force in an elegant packaging. EK designed the system to be high flow and to a certain degree it is exactly that. The combination of the thick radiator and fans and all the matching components like the pump top, block top and reservoir plexi pieces, it just adds that certain something that will take a standard custom loop over the top in a build. Bottom line is that the charts don't lie about performance and beyond aesthetics the kit has to function and it does that well with the best thermal results of a loaded processor in these charts.
The whole kit is relatively easy to assemble or disassemble the components as long as you are somewhat mechanical. If you can turn a wrench and follow the directions, there isn't anything about this kit that will slow you down. From replacing the jet in the block, on to adding a block top, even cutting the tubing and assembling it on the compression fitting couldn't have been easier. The best part about the compression fittings is that just finger tight works without leaks so there is no need to go at them with pliers and mar them up. The only thing that is an immediate drawback is the sheer size of the radiator and having two free bays for the reservoir. If your case is accommodating of those two things, the EK-Supremacy and subsequent kit is top notch with only a few slight issues.
The biggest issue is the reservoir. With the way the water flows across the entire top of the reservoir, there is no place for an outlet that won't immediately suck in air bubbles. I had the outlet on the right most port and the air flowed through the loop as if there was no reservoir to even catch it as it passed. Even when I moved to the protected center section of the reservoir, I was still drawing in air through the loop for some four days before it finally settled out. I actually had to make a Molex that I modded the wires to run the pump at 7V for a while to slow down the flow while eliminating the bubbles.Compounding this issue is the sheer strength of the DDC-3.1 with the X-TOP on it. No matter if I put the pump after the radiator, the EK-Supremacy or the BAY SPIN reservoir, the pump would almost collapse the inlet line due to the amount of suction the pump requires for intake. If there was any adjustments made to the reservoir and maybe a low power adapter for the pump would definitely reduce at least half of the issue. For the collapsing of the tubes, it has a lot to do with the choice of thin walled tubing as well. So maybe the better move is to 3/8" fittings with a 3/8" Id and Â½" OD tubing. Either way this should be addressed in some form before this kit goes to retail channels.
As for the EK-Supremacy, alone it is going to set you back â¬65.95 if you are to buy direct from EKWB. If you are in the States like I am, most likely you will be at JabTech looking at this version of the EK-Supremacy for $74.95 and it shows they are in stock. As for the entire kit; for what I assume is going to be at least $350 to obtain one, while considerably more expensive than the Swiftech solution, it is cleaner to look at with the compression fittings, but there is a lot more kit arriving on the EK solution. The block top, reservoir and the compression fittings will likely make up that $100 difference.All things considered, I think EK is on point with the pricing of these kits. If it wasn't the coolest looking pre-picked kit on the market, it also just happens to perform the best and not impose with mass amounts of noise, the EK-Supremacy and any kit based on it is the kit to have, really.
