EK Supreme HF Review


Let’s get something out of the way quickly: with (the included) Plate 1, this is the best performing block I’ve tested to date. Its restriction is very low and its thermal performance is the best at every pumping power (and at typical pumping powers, it distances itself by quite a bit over the XT). The only caveat is that it needs Plate 1 installed for it to be the absolute best, and that’s not much of a caveat considering it’s included hardware. I would actually like to see even more restrictive plates as options to see what else can be achieved from this block thermally (yes, I realize a blank is included, but home machining is not in most people’s repetoire).

The price is right, the included mounting hardware is compatible with every major socket on the market, and the build quality is exemplary. In its stock form it’s compatible with big compression fittings as well, unlike the Heatkiller 3.0 and the Apogee XT before adaptation. Even the included TIM, Arctic Cooling MX-2, is better than most included TIMs.

Unfortunately, the block is not the complete package. The mounting system, for all its flexibility, is primitive. Koolance, Swiftech, and D-Tek have vastly superior mounting systems. Additionally, the aesthetics are a little tired; with just a passing glance, its easily mistaken for the original Supreme, an outdated block. On top of that, the stock injection plate is noticeably inferior to one in the packaging; its as-delivered configuration is not ideal when it easily could be.

Overall, the performance of the block speaks loudly. Despite its primitive mounting and dated looks, this block rocks. If you’re looking for the best performing block on the market, look no further.

And again, I’d like to extend my gratitude to Performance-PCs for supplying the sample for testing.
