When we made our “how air coolers work” video, a lot of viewers were interested in the inner workings of copper heatpipes and their various means of facilitating capillary action. Today, we’re revisiting our TLDR series with a video on how closed-loop liquid coolers work. We’ll be talking about permeation, air pockets, stators, impellers, coldplates, and chemical composition of the coolant.
This content has custom-made animations that we rendered specifically for explanation of how CLCs work. GN’s Andrew Coleman modeled and animated a closed-loop cooler for the piece, referencing NZXT’s Kraken X52. Because of the level of detail and custom animations of this content, NZXT sponsored GN to put this piece together. The content applies to all liquid coolers, but particularly focuses on closed-loop products; all concepts herein can be applied to CLCs across the industry from various suppliers and manufacturers. Our technical deep-dive for today serves as a means to fully detail liquid cooling and how it works, drilling down to piano-wire granularity (literally).
We’ve been one of the most active in modding newly-launched GPUs with “hybrid” cooling solutions, and even recently began running thermal tests on VRM components alongside said mods. Before we ever did hybrid mods, NZXT launched its G10 bracket – back in 2013 – to tremendous success and adoption. That adoption died off over time, mostly due to new GPU launches that weren’t clear on compatibility, and NZXT eventually was met by competition from Corsair’s HG10.
EVGA’s closed-loop liquid cooler, named “Closed-Loop Liquid Cooler,” will begin shipping this month in 280mm and 120mm variants. We’ve fully benchmarked the new EVGA CLC 280mm versus NZXT’s Kraken X62 & Corsair’s H115iV2 280mm coolers, including temperature and noise testing. The EVGA CLC 280, like both of these primary competitors, is built atop Asetek’s Gen5 pump technology and primarily differentiates itself in the usual ways: Fan design and pump plate/LED design. We first discussed the new EVGA CLCs at CES last month (where we also detailed the new ICX coolers), including some early criticism of the software’s functionality, but EVGA made several improvements prior to our receipt of the review product.
The EVGA CLC 280 enters the market at $130 MSRP, partnered with the EVGA CLC 120 at $90 MSRP. For frame of reference, the competing-sized NZXT Kraken X62 is priced at ~$160, with the Corsair H115i priced at ~$120. Note that we also have A/B cowling tests toward the bottom for performance analysis of the unique fan design.
Relatedly, we would strongly recommend reading our Kraken X42, X52, & X62 review for further background on the competition.
Preorders are now open for the iBUYPOWER “Snowblind” system we’ve been covering for the past few months, most recently at CES 2017. The most notable aspect of Project Snowblind is the modified NZXT Noctis 450 enclosure, which uses an LCD side panel in place of a traditional clear window.
To be clear: although the buzz surrounding Project Snowblind is generally about the side panel, Snowblind systems are complete prebuilt machines and their enclosures are not available separately at this time (see our Noctis 450 review for details on the non-LCD version). As such, there are three SKUs available for preorder: Snowblind, Snowblind Pro, and Snowblind Extreme, for $1500, $1800, and $2500 respectively, with monthly payment plans optional. Additional components can be added for additional cost, but only white or silver varieties are allowed in order to give the panel maximum contrast.
NZXT’s S340 Elite builds upon the S340, but has retooled a couple of components. Most apparent, its inclusion of tempered glass means the S340 Elite now aims to adopt an industry trend, with NZXT already invested in 2016’s other trend (RGB) through the HUE+.
The refreshed S340 Elite is priced at around $100, with the S340 non-Elite still at ~$70. This makes the Elite one of the cheaper tempered glass cases on the market, coming under the new Corsair 570X by $80, the 460X by $40, and under the Cullinan by $30. Three color options are available for the S340 Elite: Flat black, black with red accents on the cable management bar, and white and black. This is a place where NZXT excels; its designers know how and where to apply accents, and they help differentiate the options so that users can feel more unique in their system builds.
In this review of the NZXT S340 Elite, we’ll be looking at thermal performance, acoustics (noise levels), cable management, and overall quality.
This year’s Black Friday, Cyber Monday, and Holiday sales continue, allowing us to compile a list of PC accessories that are aimed at giving your system a boost in aesthetics. Most our guides thus far have been focused on the performance aspect, like our “Best SSDs of 2016” guide, our guide to mechanical keyboards, to 1440p monitors, and recent two PC builds. We’ve also got some coverage of the best PSUs currently on sale, if that’s interesting.
But today, we’re here for visuals. RGB lighting products and sleeved cables are a common trend in the market in 2016 for those looking to improve their setups looks. This year, RGB has gotten big enough that only the craze for tempered glass rivals its popularity; there are RGB fans, mouse pads, controllers, and peripherals of all sorts.
Here’s the shortlist:
NZXT's H440 came out a few years ago to critical acclaim, including kind words from our own site, and has stuck around since. The case has been rehashed a few times since launch, including an H440v2 iteration (which Newegg calls "H440 Steel") that marginally increased the gap between mesh side panels and the chassis, improving airflow. The case has also been sold with Razer's branding and green underglow LEDs and with an eSports finish.
And it's being re-re-refreshed again today, with a new "Hyper Beast" skin, as sourced from CSGO's M4A1-S. The H440 Hyper Beast edition is going for maximum cheese by limiting its production run to 1337 units, each numbered with a badge. Unit #1337, of course, would be the one to want.
A new series of Kraken liquid coolers from NZXT marks the first time that Asetek has afforded a customer the responsibility of designing custom electronics, which NZXT deploys for RGB LED control and future firmware revisions. The coolers use Gen5 Asetek pumps with custom-built pump blocks, "infinity mirror" pump plates, and NZXT fans that differentiate the X42, X52, and X62 line-up from Corsair's nearby competition. Corsair most heavily competes in the 240mm market -- that'd go up against the X52 -- where the H100iV2 is priced at ~$105 right now, though the H90 also competes with the X42.
Our disassembly of the Kraken X42 liquid cooler showed the device's internals, explained that the high-quality of design and component selection made for a promising set of tests, but didn't dive into the details. This review looks at the temperature performance and noise performance, along with a noise-temperature curve, of the new NZXT Kraken X62, X52, and X42 liquid coolers, particularly matched against the H100iV2. We've got the EK WB Predator XLC 280 as a high-end alternative, alongside the Be Quiet! Dark Rock 3 as a $50 air cooler, just to provide a baseline.
NZXT's new Kraken X42, X52, and X62 liquid coolers were announced today, all using the new Asetek Gen5 pump with substantial custom modifications. The most direct Gen5 competition would be from Corsair, makers of the H115i and H100iV2, each priced to compete with the Kraken X42 ($130) and X52. The Corsair units, however, are using an unmodified Asetek platform from top-to-bottom, aside from a couple of Corsair fans. NZXT's newest endeavor had its components dictated by NZXT, including a custom (and fairly complex) PCB for fan speed, pump speed, and RGB control, planted under a custom pump plate with infinity mirror finish. The unit has gone so far as to demand a double-elbow barb for pose-able tubes, rather than the out-the-top setup of the Asetek stock platform – that's some fastidious design.
As for how we know all of this, it's because we've already disassembled a unit. We decided to dismantle one of our test-complete models to learn about its internals, since we're still waiting for the X52 and X62 models to be review-ready. We've got a few more tests to run.
Before getting to the tear-down, let's run through the specs, price, and availability of NZXT's new Kraken X42, X52, and X62 closed-loop liquid coolers.
It's crazy to think that someone had to “innovate” – to use the word lightly – and apply non-beige paint to PC cases. There had to be a first for that – just like there was a first to package a case in a non-brown cardboard box. In the former instance, we believe NZXT to be the pioneer in painted cases, though Antec shares some credit for early industry innovations (like box art). NZXT's Guardian was among the first painted cases available for DIY enthusiasts, and further emphasized its rebellious nature by outfitting the left side panel with an acrylic window. For 2003, these were leading advancements in case design.
And it fits, too. We also see NZXT as the trend-setter for power supply shrouds with the launch of its critically acclaimed H440 chassis, then later its S340. Since the H440 launched, we've seen a market shift where nearly every $70-$100 enclosure is outfitted with a PSU shroud. Corsair's 400C and 600C cases, the Rosewill Gungnir and Cullinan, the Phanteks P400, the SilverStone RL05 – they all follow this trend.
