The Phanteks P400A gave us tentative hope at Computex when we saw its move to a fine mesh front panel, similar to what Cooler Master did with the NR600. The P400A follows-up on the original Eclipse P400, but while keeping the base tooling, it massively overhauls the panel design to move away from a closed-off, suffocated front and toward a more open mesh. Phanteks also avoids the trap that many fall into by eliminating a dust filter, instead relying on the fine mesh as a filter and keeping airflow as open as possible. In today’s testing, we’ll look at the Phanteks P400A RGB for thermals and acoustics, but we’ll also test the white panel versus black panel to see if the paint thickness matters, then throw the original P400 panel on for comparison.
The original Phanteks Eclipse P400 released circa 2016. The P400 is a case that launched during the initial explosion of S340-esque cases with sealed front panels, full-length PSU shrouds, and no optical drive support. Phanteks has gotten an impressive amount of use out of that tooling over the years, most recently with the case we’re reviewing today: the mesh-fronted P400A that comes as a $70 base model with two fans and a fan controller or a $90 RGB model with three fans and an LED controller. We’ll be covering the $70 model in a separate piece, since this review is already full to the brim with testing of the P400A’s front panel.
This hardware news episode mostly focuses on alleged Threadripper documentation that we received through a leak, including discussion of the sTRX4 and sWRX8 processors that are listed in said document. The "4" and "8" are indicative of memory channel count, though we don't fully know what name or release date AMD intends to give these CPUs. AMD's Threadripper 3000 series CPUs will be competing with Intel in HEDT, where Intel is presently focusing effort for its next major release cycle. Beyond the Threadripper discussion, we also talk about Intel and AMD bickering with each other like children (I'll turn this car around right now!), Der8auer's survey, USB4 spec, and the Steam Hardware Survey.

We’ve already reviewed the reference RX 5700 XT, the Sapphire Pulse model that we received as a frontrunner for board partners, and the MSI Evoke OC, which was overall poor value when compared to cheaper solutions on the market. Now, we’re looking at the Gigabyte Gaming OC card, the first triple-axial fan contender in our RX 5700 series benchmarks. It all comes down to thermals and noise with these, as gaming performance is functionally the same between each card when stock, and so we’ll focus-down on if Gigabyte can achieve competitive thermals at equivalent noise to the Sapphire and MSI cards. At $420 MSRP, the Gigabyte Gaming OC is priced around the Pulse and just below the Evoke.
For this testing, we’re focusing most heavily on thermals and noise. As a reminder, and we’ll say this in the conclusion as well, board partner cards ultimately come down to thermal and acoustic differences. There are a few that have extreme impact on XOC capabilities, like a KINGPIN or HOF card, but none of the 5700 XTs that we’ve yet looked at focus on that market. Gaming benchmarks become unimportant, as performance remains unchanged in nearly all partner designs. The one exception is the Evoke OC, which posted roughly a +2% performance advantage over baseline reference/Pulse performance, but otherwise, expect no meaningful or even measurable performance impact in gaming from these cards. The biggest gain is in massive quality of life improvements, such as reduced noise levels (in a noticeable way), reduced thermals, features like extra VBIOS on-board (the Pulse has this), or fitment advantages.
Memory speed on Ryzen has always been a hot subject, with AMD’s 1000 and 2000 series CPUs responding favorably to fast memory while at the same time having difficulty getting past 3200MHz in Gen1. The new Ryzen 3000 chips officially support memory speeds up to 3200MHz and can reliably run kits up to 3600MHz, with extreme overclocks up to 5100MHz. For most people, this type of clock isn’t achievable, but frequencies in the range of 3200 to 4000MHz are done relatively easily, but then looser timings become a concern. Today, we’re benchmarking various memory kits at XMP settings, with Ryzen memory DRAM calculator, and with manual override overclocking. We’ll look at the trade-off of higher frequencies versus tighter timings to help establish the best memory solutions for Ryzen.
One of the biggest points to remember during all of this -- and any other memory testing published by other outlets -- is that motherboard matters almost more than the memory kit itself. Motherboards are responsible for most of the timings auto configured on memory kits, even when using XMP, as XMP can only store so much data per kit. The rest, including unsurfaced timings that the user never sees, are done during memory training by the motherboard. Motherboard manufacturers maintain a QVL (Qualified Vendor List) of kits tested and approved on each board, and we strongly encourage system builders to check these lists rather than just buying a random kit of memory. Motherboard makers will even tune timings for some kits, so there’s potentially a lot of performance lost by using mismatched boards and memory.
This week's hardware news has a litigation theme, including battles between GlobalFoundries and TSMC and AMD and the public. In the former, it's a fight over intellectual property and alleged infringements; in the latter, it's been resolved, and buyers of the Bulldozer CPUs affected can lay claim to $35 (unless a lot of people claim it, in which case it'll dilute further). Beyond that, we'll be talking RX 5700 stock, sales numbers, and Intel's banter with AMD.

The O11 Dynamic was a case we liked enough to keep around for housing one of our work PCs. The layout is nonstandard, from the side intake vents to the placement of the PSU and storage, but it works. It may be the only case we’ve ever tested with a completely sealed-off glass front panel that still managed to perform actually well in testing. The O11 Air variant impressed us somewhat less, but improved substantially when the dust filtration was removed. Now, in 2019, Lian Li is introducing the O11 XL, a larger version of the original case, still bearing the Der8auer badge for his initial work on the O11 Dynamic.
Like the Dynamic, this case is meant to be used for water cooling builds, but our standardized test bench is used for air testing. This is still useful to determine the performance capabilities of the case, as it’ll all scale when comparing one case to the next, but note that water cooling can obviously brute-force its way past a lot of thermal issues. Still, the O11 Dynamic made an actually good air-cooled case thanks to the bottom intake and side intake options, so even though it looks best as an aquarium, it didn’t have to be one.
This is a prototype, and it’s one of the most unique closed-loop liquid coolers we’ve ever reviewed. Cooler Master sent us their first engineering sample of a new 200mm closed-loop liquid cooler – or AIO, as some like to call them – and it’s built for the mini-ITX Cooler Master H100 case. Technically, a cooler like this could also be used to mount to other cases with 200mm fans, like the H500M or H500 cases, although the tubes would need to be longer. The cooler tries to solve the problem of matching radiators to 200mm case intake fans, since most radiators work best with 120 or 140 fans, and would exhibit worse performance without leveraging the full surface area of a 200mm fan. Today, we’re benchmarking this new cooler on our standardized bench.
The Cooler Master 200mm closed-loop liquid cooler is as yet unnamed, but it’ll be included in a bundle with the H100 MITX case from Computex. The total bundle cost should be around $100 when all is done, but standalone units are unlikely to be sold right now. Cooler Master noted that it would read our YouTube comments section to help determine if there’s enough demand for a 200mm CLC standalone, but that it otherwise is targeting this cooler specifically for its new mini-ITX case with one 200mm fan.
The biggest challenge with 200mm fans, as always, is that none of them are standardized. Cooler Master designed this cooler to fits its CM MF-200R fans, and so fans with alternate hole spacing – like the Noctua 200mm fans – will not fit without twist ties and clamps. We still tested the cooler with both the CM MF-200R and Noctua 200mm fans, but the Noctua unit does not natively fit.
Separately, we’ll re-embed some airflow LPM tests from our previous CM vs. Noctua 200mm fan comparison.
We’ve gotten into the habit of fixing video cards lately, a sad necessity in an era plagued with incomplete, penny-pinching designs that overlook the basics, like screw tension, coldplate levelness, and using thermal pads that are about 60% smaller than they should be. MSI’s RX 5700 XT Evoke OC (review here) is the newest in this growing list of cards that any user could fix, unfortunately, and it’s for reasons we illustrated best in our tear-down of the card. Our testing illustrated that its cooling capabilities are sub-par when compared to the Sapphire Pulse, and not only that, but that the memory temperatures are concerningly high when noise-normalized in our benchmarks. Today, we’re fixing that with properly sized thermal pads.
"Integer scaling" has been a buzz phrase for a few weeks now, with Intel first adding integer scaling support to its driver set, and now NVIDIA following. This week, we'll be talking more about what that even means (and where it's useful), news on AMD's RDNA whitepaper and CrossFire support, Intel's Comet Lake CPUs (and naming), and a few minor topics.

The Coolman Threebody is a case we bought in the Shenzhen SEG E-Market in China and had sent back to us, along with a couple other items that might show up in future content. This is less of a review and more of a look at some cool features in a weird case, since most of our audience can’t wander down to Shenzhen and pick one up. Maybe Western-market case manufacturers can take some cues from the Threebody’s design. Asking price at the market was $66 US, and we paid $60 for it.
The most optimistic feature of the Threebody is the big yellow warning sticker that says TEMPERED GLASS: Please handle with care. Both translucent side panels are very definitely plastic and not glass, as curved glass panels are a luxury even for major manufacturers like Cooler Master. It’s not a lie since the small pane on top of the case is glass, but this is also the smallest and most hidden of the three clear panels, so maybe they should have gone for plastic there as well.
