Our old coverage of the NZXT H700i included a lengthy section on what we deemed a bug-filled fusion of hardware and software that would be a waste of money even if it worked perfectly, with that device finding its way into a trashcan during the review. That was the “Smart Device” version 1, which was reclaimed from the trashcan for exactly this content piece. The intended function of this little black box was to automatically modulate fan speeds to find an optimal balance between noise and thermal performance, relying on internal microphones to gauge the noise-to-thermal response. In practice, its function is to raise the MSRP of the H700 and H710 by an average of $30. We didn’t actually get any performance numbers for the original smart device because we could never successfully coach it through the software calibration phase, something NZXT claims to have fixed in the two years since. Today, we’re testing to see if the smart device is still a net negative for the intelligence of the H-series cases.
It’s been a couple years now since we reviewed the H700i, and to NZXT’s credit, they do sell a cheaper version of the case without the device, so we’ll pause our diatribe there for now. Upon review of the H700i, we asked for an H700d -- or dumb, as dubbed by our Patreon community -- that would rid of the smart device and allow a lower price-point. This was eventually granted across the case family, and we’ve been happy to recommend the H700 as an option in the $130 to $150 category ever since.
As we alluded to in our NZXT H510 Elite review and H710 review, though, the Smart Device version 2 is here, and we’ve finally gotten around to testing it. The PCB inside the new Smart Device is visibly different, but the aim of this review is to see whether different is also better. Also, to actually review the Smart Device, since the software was too broken to test last 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.
The revolution of 200mm fans was a short-live one. Large fans are still around, but the brief, bombastic era of sticking a 200mm fan in every slot didn’t last long: The CM HAF X, NZXT Phantom 820, SilverStone Raven 02 (180mm), Throne & Thor, and 500R all have designs that have largely been replaced in the market. That replacement comes in the form of an obsession with the word “sleek” in marketing materials, which generally means flat, unvented paneling that would conflict with the poorer static pressure performance of large fans. That’s not to say 200mm fans are inherently good or bad, just that the industry has trended away from them.
That is, until the Cooler Master H500P, which runs 2x MasterFan MF200R units dead-center, fully garnished with RGB LEDs. We didn’t necessarily like the H500P in its stock configuration (but did fix it), but we know the case is popular, and it’s the best test bench for 200mm fans. There’s a good chance that purchasers of the NF-A20 are buying them for the H500P.
And that’s what we’re reviewing today. In this benchmark, we’re reviewing the Noctua NF-A20 200mm fans versus the Cooler Master MasterFan MF200Rs, which come stock with the H500P. The MF200R fans will almost certainly become available separately, at some point, but presently only ship with the H500P.
Following an initial look at thermal compound spread on AMD’s Threadripper 1950X, we immediately revisited an old, retired discussion: Thermal paste application methods and which one is “best” for a larger IHS. With most of the relatively small CPUs, like the desktop-grade Intel and AMD CPUs, it’s more or less been determined that there’s no real, appreciable difference in application methods. Sure – you might get one degree Centigrade here or there, but the vast majority of users will be just fine with the “blob” method. As long as there’s enough compound, it’ll spread fairly evenly across Intel i3/i5/i7 non-HEDT CPUs and across Ryzen or FX CPUs.
Threadripper feels different: It’s huge, with the top of the IHS measuring at 68x51mm, and significantly wider on one axis. Threadripper also has a unique arrangement of silicon, with four “dies” spread across the substrate. AMD has told us that only two of the dies are active and that it should be the same two on every Threadripper CPU, with the other two being branded “silicon substrate interposers.” Speaking with Der8auer, we believe there may be more to this story than what we’re told. Der8auer is investigating further and will be posting coverage on his own channel as he learns more.
Anyway, we’re interested in how different thermal compound spreading methods may benefit Threadripper specifically. Testing will focus on the “blob” method, X-pattern, parallel lines pattern, Asetek’s stock pattern, and AMD’s recommended five-point pattern. Threadripper’s die layout looks like this, for a visual aid:
Because of the spacing centrally, we are most concerned about covering the two clusters of dies, not the center of the IHS; that said, it’s still a good idea to cover the center as that is where the cooler’s copper density is located and most efficient.
Our video version of this content uses a sheet of Plexiglass to illustrate how compound spreads as it is applied. As we state later in the video, this is a nice, easy mode of visualization, but not really an accurate way to show how the compound spreads when under the real mounting force of a socketed cooler. For that, we later applied the same NZXT Kraken X62 cooler with each method, then took photos to show before/after cooler installation. Thermal testing was also performed. Seeing as AMD has permitted several other outlets to post their thermal results already, we figured we'd add ours to the growing pool of testing.
Modern humans used to hang undesirables in the town square and light “witches” aflame. For lack of a witch, PC hardware enthusiasts prefer to seek out companies that other internet users have suggested as wrongdoers. Legitimate or not, the requirement to stop and think about something need not apply here – we need more rage for the combustion engine; this thing doesn’t run on neutrality.
Posting a concern about a product, like Reddit user Kendalf did, cannot be praised enough. This type of alert gets attention from manufacturers and media alike, and means that we can all work together to determine if, (1) there is actually an issue, and (2) how we can fix it or work around it. The result is stronger products, hopefully. As stated in the lengthy conclusion below, though, it’s an unfortunate side effect that other commenters then elect to blow things out of proportion for need to feel upset about something. There’s always room for a one-off defect, for misunderstandings of features, or just a bad batch. There’s also room for a manufacturer to really screw up, so it just depends on the situation. Ideally, the mobs remain at bay until numerous people have actually verified something.
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.
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).
MSI’s new-ish GS43 Phantom Pro laptop made an appearance at PAX East this weekend, where we’re presently RNG-ing some tear-downs and live benchmark demonstrations. Our first content piece discussed keyboard input latency testing, and our second piece – this one – will open up the Phantom Pro for a closer look.
As a quick side note, MSI does have “new” camo finish GTX 1060s, Z270 motherboards, and GE62 laptops. We show those briefly in the video, though it’s really not a focal point for today.
Building-up a semi-custom liquid cooling loop is a bit of a new trend, spawned from a surge in AIO dominance over the market. The ease of installation for AIOs greatly exceeds what’s possible with an open loop, with the obvious loss of some customization and uniqueness. The cooling loss, although present, isn’t necessarily a big factor for the types of buyers interested in AIO CLCs rather than open-loop alternatives. Ever since we saw PNY’s solution years ago, though, and then more recently EVGA’s quick disconnect solution, the market has begun to burgeon with semi-custom loop “CLCs.”
An example of these semi-custom CLCs would be the EK Waterblocks Predator XLC 280 that we benchmarked in our Kraken X62 review. Today’s review also focuses on one of these semi-custom liquid cooling solutions, featuring benchmarks of the Alphacool Eiswolf GPX Pro on a GTX 1080. Our testing looks into thermal performance under baseline conditions (versus a GN Hybrid DIY option), frequency stability and performance, overclocking, and FPS impact. We’ve got a few noise and CPU tests too, though this will primarily focus on the GPU aspect of the cooling. The Alphacool Eiswolf GPX Pro does not work as an out-of-box product, necessitating our purchase of the Alphacool Eisbaer to hook into the system (CPU cooler + radiator). The Eiswolf GPX Pro is a $130 unit, and the Eisbaer cost us ~$145.

Last week, Gigabyte announced the Gigabyte XTC700 tower CPU cooler to go along with their “Xtreme Gaming” peripherals, which include a slew of new products that mostly feature RGB LEDs. The XTC700 comes with an RGB top plate featuring the Gigabyte Xtreme Gaming logo, a pair of 120mm fans for push/pull, and Gigabyte branding for a unified aesthetic with Gigabyte motherboards and video cards. The RGB top plate, like all RGB Xtreme Gaming products, will be controllable through Gigabyte’s Spectrum software. The Gigabyte XTC700 will support Intel sockets 2011, 1366, 1156, 1155,1151,1150, 775, including the upcoming Kaby Lake. Additionally, the cooler will support AMD’s FM2+, FM2, FM1, AM3+, AM3, AM2+, AM2, 939, and 754 sockets -- basically everything from each vendor.
