Corsair, NZXT, Thermaltake, and EVGA closed-loop liquid coolers presently have no official AM4 retention kit support, leaving the companies exposed to questions from customers waiting to build Ryzen systems. This delay has affected the most popular coolers presently on the market, to include the Corsair H100iV2, H115i, NZXT X62/52/42, and new EVGA CLCs, but hasn’t affected all CLCs available. Some SIs, for instance, have blown throw stock of CoolIT-supplied CLCs from Corsair (like the H110i and H60), but haven’t been able to fill orders of units that use a four-screw mounting mechanism.

We have details for you on when your brackets will be available and on what caused the delays to begin with. This content contains several official comments and statements from the affected cooling manufacturers.

We’ve fixed the GTX 1080 Ti Founders Edition ($700) card. As stated in the initial review, the card performed reasonably close to nVidia’s “35% > 1080” metric when at 4K resolutions, but generally fell closer to 25-30% faster at 4K. That’s really not bad – but it could be better, even with the reference PCB. It’s the cooler that’s holding nVidia’s card back, as seems to be the trend given GPU Boost 3.0 + FE cooler designs. A reference card is more versatile for deployment to the SIs and wider channel, but for our audience, we can rebuild it. We have the technology.

“Technology,” here, mostly meaning “propylene glycol.”

Our review of the nVidia GTX 1080 Ti Founders Edition card went live earlier this morning, largely receiving praise for jaunts in performance while remaining the subject of criticism from a thermal standpoint. As we've often done, we decided to fix it. Modding the GTX 1080 Ti will bring our card up to higher native clock-rates by eliminating the thermal limitation, and can be done with the help of an EVGA Hybrid kit and a reference design. We've got both, and started the project prior to departing for PAX East this weekend.

This is part 1, the tear-down. As the content is being published, we are already on-site in Boston for the event, so part 2 will not see light until early next week. We hope to finalize our data on VRM/FET and GPU temperatures (related to clock speed) immediately following PAX East. These projects are always exciting, as they help us learn more about how a GPU behaves. We did similar projects for the RX 480 and GTX 1080 at launch last year.

Here's part 1:

EVGA’s CLC 120 cooler fell on our bench shortly after the EVGA CLC 280 ($130), which we reviewed last week against the NZXT X62 & Corsair H115i. The EVGA CLC 120 prices itself at $90, making it competitive with other RGB-illuminated coolers, but perhaps a bit steep in comparison to the cheaper 120mm AIOs on the market. Regardless, 120mm territory is where air coolers start to claw back their value in performance-to-dollar; EVGA’s chosen a tough market to debut a low-end cooler, despite the exceptionally strong positioning of their CLC 280 (as stated in our review).

Before diving in to this review, you may want to read the EVGA CLC 280 review, NZXT Kraken X42/X52/X62 review, or its subsequent tear-down.

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. 

Deepcool has made their mark on the PC hardware industry by including liquid cooling solutions in their cases. Deepcool’s Genome cases had a helical reservoir built into the front of the case. At CES 2017, Deepcool unveiled three new liquid-cooled cases, a show case, and two similar RGB fan sets.

The MF120 and MF120GT are the two new fans. The MF120GT uses a traditional housing design with the LEDs in an “X” pattern across the middle. The MF120 housing implements a frameless design with the RGB LEDs running nearly parallel through the middle. Both models share several properties: the housings are aluminum, the blades have a unique design meant to improve air pressure, they rotate on FDBs, and the fans are PWM adjustable between 500 and 2200 RPM. The plan is to sell 3 fans and a controller for $100 USD, and the system will be controlled through an Android or Apple mobile app. Unfortunately, there are no plans for a Windows desktop control app at the moment.


At the tail-end of our CES 2017 coverage, our visit to the Thermaltake showroom provided a look at upcoming cooling products – as the name might suggest – alongside some spin-offs of existing product lines. The more playful side of the room was outfitted with an original Donkey Kong arcade cabinet look-alike, a case mod by “Thermal Mike” for which we’ll post a separate video, while the rest of the room featured liquid and air cooling products.

Today's focus is on the Thermaltake P1 TG mini-ITX wall-mount enclosure, the Rainbow AIO CLC, and the Engine 27 Sandia-style ($50) cooler.

EVGA’s CES 2017 suite hosted a new set of 10-series GPUs with “ICX” coolers, an effort to rebuff the cooling capabilities of EVGA’s troubled ACX series. The ACX and ICX coolers will coexist (for now, at least), with each SKU taking slightly different price positioning in the market. Although EVGA wouldn’t give us any useful details about the specifications of the ICX cooler, we were able to figure most of it out through observation of the physical product.

For the most part, the ICX cooler has the same ID – the front of the card is nigh-identical to the front of the ACX cards, the LED placement and functionality is the same, the form factor is effectively the same. That’s not special. What’s changed is the cooling mechanisms. Major changes include EVGA’s fundamentally revamped focus of what devices are being cooled on the board. As we’ve demonstrated time and again, the GPU should no longer be the focal point of cooling solutions. Today, with Pascal’s reduced operating voltage (and therefore, temperature), VRMs and VRAM are running at more significant temperatures. Most of the last-gen of GPU cooling solutions don’t put much focus on non-GPU device cooling, and the GPU cores are now efficient enough to demand cooling efforts be diverted to FETs, capacitor banks, and potentially VRAM (though that is less important).

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.

This unit was provided by viewer and reader ‘Eric’ on loan for review. Thanks, Eric!

GN reader ‘Eric’ reached-out to us to loan his Alphacool Eiswolf GPX Pro cooling block, which we’ve now applied to a GTX 1080 Founders Edition card. The Eiswolf build process isn’t too difficult – certainly easier than the tear-down of the average FE card. The Eiswolf GPX Pro has an on-card pump with designated in/out tubes, each terminating in threaded quick release valves that hook into a semi-open loop system. We later purchased an Alphacool Eisbaer for our radiator and CPU cooler, then connected them all together.

The review of the Eiswolf will be posted tomorrow, followed shortly by a look at EK WB’s Predator XLC. For today, we’re just posting the build log that our Patreon backers have helped produce.
