Our Computex 2018 coverage continued as we visited the BeQuiet! booth. This year, Be Quiet! announced the new Dark Rock Pro for socket TR4 (Threadripper), timely for Threadripper 2, and also showed a trio of refreshed cases -- the Silent Base 801, 601, and Dark Base 900 Rev 2.0.
The Dark Rock Pro TR4 is specifically designed with AMD’s Threadripper socket TR4 in mind. The Dark Rock Pro’s only real difference from previous iterations is the new full coverage block for Threadripper. The new cold plate is designed to help ensure full die coverage on Threadripper, which we discussed back in August of last year. We’ve previously found there to be a measurable difference when using TR4 full coverage coolers vs. non-TR4 ones. Price and release date were not available at this time.
The NZXT M22 is one of the stranger liquid coolers made by a relatively large liquid cooling manufacturer. NZXT dumped Asetek for this 120mm closed-loop cooler, instead opting for a pump-in-radiator design that circumvents Asetek patents and permits sale in the US. The M22 is a complement to NZXT’s Asetek products at the high-end, but comes in at $100 and 120mm. That’s a bit high for a 120mm liquid cooler, particularly considering that competition from EVGA’s CLC 120 comes in at $70 and is made by the familiar Asetek, but its performance may make up for the price differential. Today, we’ll find out.
Primary competition in this price class includes NZXT’s own Kraken X42, a 140mm Asetek-made design, and 240mm units from the same price class. NZXT’s M22 ships for $100 MSRP, and at that price, it’s competing (strictly in price) with the likes of the EVGA CLC 240, the Corsair H100i V2, and NZXT’s units. If we look strictly at size class, the EVGA CLC 120 competes most directly at $70. Despite its low price, that’s still a modern Asetek unit; it uses the same pump as any higher-end cooler, just has fewer fans. It’s not cheap garbage – it’s not something we recommend, either, but it’s not going to fall apart.
It’s a fierce market at $100. Even air coolers would reach equivalence or superior performance than NZXT’s M22. They’re going for one demographic, and one only: Has RGB LEDs and is exactly 120mm. That’s it. That’s the demo. If you’re not that, it’s really not worth the time or money to grab the M22.
To NZXT’s credit, the LED integration is the best-in-class for a 120mm liquid cooler. It’s also expensive, so that makes for an odd combination of size and price.
NZXT’s Kraken X72 closed-loop liquid cooler is another in the XX2 series, following the 280mm X62 that we previously reviewed. The X72 is a 360mm cooler, putting it in more direct competition with the Corsair H150i Pro (the first to feature a 6th-gen pump) and Fractal S36, and indirect competition – in performance only – with the EVGA CLC 280.
NZXT’s X72 costs $200, making it one of the most expensive CLCs on the market. The Floe 360 lands at around $184, the EK Phoenix 360 – a semi-open solution – is the only one that lands significantly higher. The X72 still uses the same pump design as when we tore-down the X42, running Asetek’s 5th Gen pump and a custom, NZXT-designed PCB for RGB lighting effects. Functionally, 5th Gen has proven to be marginally superior – technically – to its 6th Gen for outright cooling performance. We’re talking nearly margins of error. The newest generation is presently only used on Corsair’s H150i and H115i Pro products, as Corsair largely dictated what went into the 6th generation. Major differences are made-up by the metal impeller, similar to the one used by Dynatron in old Antec Kuhler products, rather than a 3-prong plastic impeller. These don’t perform differently in terms of thermals, but there should be reduced susceptibility to heated liquid, and theoretically reduced hotspots as a result of the new 6th Generation design. That doesn’t manifest in outright performance, but might manifest in endurance. We won’t know for a few years, realistically.
Our primary tests for the NZXT Kraken X72 review and benchmark include the following:
- 100% fan / 100% pump
- 100% fan / silent pump
- 63% fan (40dBA)
EK Waterblocks makes some of our favorite quick release valves, but their previous attempt at a semi-open loop liquid cooler – the EK Predator – terminated after an overwhelming amount of issues with leakage. It was a shame, too, because the Predator was one of the best-performing coolers we’d tested for noise-normalized performance. Ultimately, if it can’t hold water, it’s all irrelevant.
EK is attempting to redeem themselves with the modular, semi-open approach set-forth with the new EK-MLC Phoenix series. A viewer recently loaned us the EK-MLC Phoenix 360mm cooler and Intel CPU block ($200 for the former, $80 for the latter), which we immediately put to work on the bench. This review looks at the EK-MLC Phoenix 360mm radiator and CPU cooling block, primarily contending against closed-loop liquid coolers (like the H150i Pro and X62) and EK's own Fluid Gaming line.
We’re reviewing the 360mm Enermax TR4 Liqtech cooler today, matched-up against the 240mm variant and with a special appearance from the Noctua NH-U14S TR4 unit. We previously benchmarked the Enermax Liqtech 240 TR4 closed-loop liquid cooler versus the Noctua NH-U14S, resulting in somewhat interesting findings. The larger version of the Liqtech, the 360mm cooler, is now on the bench for comparison with an extra fan and a wider radiator. The NH-U14S returns, as does the X62 (mostly to demonstrate smaller coldplate performance).
We’re still using our 1950X CPU on the Zenith platform, overclocked to 4.0GHz at 1.35Vcore. The point of the OC isn’t to drive the highest possible clock, but to generate a larger power load out of the CPU (thus stressing to a point of better demonstrating performance deltas).
At time of publication, the Enermax Liqtech 240 TR4 is priced at ~$130, with the 360 at ~$150, and with the NH-U14S at ~$80.
This testing kicked-off because we questioned the validity of some cooler testing results that we saw online. We previously tested two mostly identical Noctua air coolers against one another on Threadripper – one cooler had a TR4-sized plate, the other had an AM-sized plate – and saw differences upwards of 10 degrees Celsius. That said, until now, we hadn’t tested those Threadripper-specific CPU coolers versus liquid coolers, specifically including CLCs/AIOs with large coldplates.
The Enermax Liqtech 240 TR4 closed-loop liquid cooler arrived recently, marking the arrival of our first large coldplate liquid cooler for Threadripper. The Enermax Liqtech 240 TR4 unit will make for a more suitable air vs. liquid comparison versus the Noctua NH-U14S TR4 unit and, although liquid is objectively better at moving heat around, there’s still a major argument on the front of fans and noise. Our testing includes the usual flat-out performance test and 40dBA noise-normalized benchmarking, which matches the NH-U14S, NH-U12S, NZXT Kraken X62 (small coldplate), and Enermax Liqtech 240 at 40dBA for each.
This test will benchmark the Noctua NH-U14S TR4-SP3 and NH-U12S TR4-SP3 air coolers versus the Enermax Liqtech 240 TR4 & NZXT Kraken X62.
The units tested for today include:
EK’s Fluid Gaming liquid cooling kits target an entry-level, first-time loop-builder, strictly using aluminum across all Fluid Gaming components for reduced cost. This decision positions EK nearly against itself: The company has boasted copper loop materials as superior to CLCs for so long now that shipping an aluminum-built product has inspired official blog posts in defense of the choice. This is primarily one of cost, as opting for aluminum – much like the CLC makers – allows EK to sell entry-level, CPU-only kits in the sub-$200 market. The EK Fluid Gaming 240mm solution ships at $160 and includes a 240mm radiator, a standalone pump, soft tubing, coolant (but buy your own distilled water), two fans, fittings, and a CPU block. The result is a low-end open-loop starter pack that includes all necessary parts, but ultimately costs more than nearby CPU-only CLCs (like the H100iV2 at $110, the EVGA CLC 280 at $130, and the Kraken X62 at $156).
Of course, the idea is to go beyond CPU-only cooling: This starter kit is accompanied by a full Fluid Gaming version from EK, priced at $240 and equipped with a Pascal GPU block. In total, EK’s available Fluid Gaming kit options include:
Before Vega buried Threadripper, we noted interest in conducting a simple A/B comparison between Noctua’s new TR4-sized coldplate (the full-coverage plate) and their older LGA115X-sized coldplate. Clearly, the LGA115X cooler isn’t meant to be used with Threadripper – but it offered a unique opportunity, as the two units are largely the same aside from coldplate coverage. This grants an easy means to run an A/B comparison; although we can’t draw conclusions to all coldplates and coolers, we can at least see what Noctua’s efforts did for them on the Threadripper front.
Noctua’s NH-U14S cooler possesses the same heatpipe count and arrangement, the same (or remarkably similar) fin stack, and the same fan – though we controlled for that by using the same fan for each unit. The only difference is the coldplate, as far as we can tell, and so we’re able to more easily measure performance deltas resultant primarily from the coldplate coverage change. Noctua’s LGA115X version, clearly not for TR4, wouldn’t cover the entire die area of even one module under the HIS. The smaller plate maximally covers about 30% of the die area, just eyeballing it, and doesn’t make direct contact to the rest. This is less coverage than the Asetek CLCs, which at least make contact with the entire TR4 die area, if not the entire IHS. Noctua modified their unit to equip a full-coverage plate as a response, including the unique mounting hardware that TR4 needs.
The LGA115X NH-U14S doesn’t natively mount to Threadripper motherboards. We modded the NH-U14S TR4 cooler’s mounting hardware with a couple of holes, aligning those with the LGA115X holes, then routed screws and nuts through those. A rubber bumper was placed between the mounting hardware and the base of the cooler, used to help ensure even and adequate mounting pressure. We show a short clip of the modding process in our above video.
Deepcool was at Computex this year with what seemed like an emphasis on cases and RGB lighting, although they did have a new CPU cooler to show off. Many of these cases seem to be updated models of previously announced cases at CES 2017, which are still pending release in the North America market.
Continuing our Coverage of Computex 2017, we met with the Be Quiet! team at their booth to discuss some of their new and upcoming products. We took a look at their Silent Loop CLC CPU cooler, the new SFX-L PSU, the Shadow Rock TF2 air cooler, and the limited edition Dark Base Pro 900 - White Edition case.
The Dark Base Pro 900 was a case we covered last year at Computex, if it feels familiar. This year, Be Quiet! displayed their new iteration of the Dark Base Pro 900 - now in white. The White Edition uses the exact same tooling as the Dark Base Pro 900, with changes entirely cosmetic. Be Quiet! reps noted that the color-matching process was the most time consuming, and that the run will be limited at first to gauge market reception. The first all white case from Be Quiet! will be limited to 2000 units worldwide, with a specific number being given to each enclosure (a nameplate in the top-right corner, near the drive cages). The White Edition will ship with an included three 140mm Silent wings 3 fans in black, contrasting the white (we’re not sure if we like that just yet), and hosts all the usual features of the DBP900. The chassis is capable of hosting three 140mm fans at the front, another three 140mm fans on top, a single 140mm at the rear for exhaust, and another single 140mm fan at the bottom, near the PSU; that brings it up to eight possible fans in total.
