We have a long, known history with the Cooler Master H500P. Our review set the stage, with our mesh mod “fixing” the product (as we said), and the disappointment build closing-out the year. Although Cooler Master didn’t particularly like what we had to say (and challenged us on the mesh mod), it seems that the company took the criticism to heart. Nearly every issue we complained about has been fixed. The company never told us about these changes, of course – we had to hear about it from you all, via Twitter – but we found out, and we visited the suite to look at the H500P Mesh and H500M.

The H500P Mesh enclosure fixes these primary concerns from our review: (1) The case falling apart, (2) the limited intake, (3) the power supply shroud installation procedure, and (4) the left panel no longer ‘wiggles’ or ‘wobbles’ side-to-side.

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.

Our review of Cooler Master’s H500P primarily highlighted the distinct cooling limitation of a case which has been both implicitly and explicitly marketed as “High Airflow.” The case offered decidedly low airflow, a byproduct of covering the vast majority of the fan – the selling point of the case – with an easily removed piece of clear plastic. In initial testing, we removed the case’s front panel for a closer look at thermals without obstructions, finding a reduction in CPU temperature of ~12~13 degrees Celsius. That gave a better idea for where the H500P could have performed, had the case not been suffocated by design, and started giving us ideas for mesh mods.

The mod is shown start-to-finish in the below video, but it’s all fairly trivial: Time to build was less than 30 minutes, with the next few hours spent on testing. The acrylic top and front panels are held in by double-sided tape, but that tape’s not strong enough to resist a light, sheer force. The panel separates mostly instantly when pressed on, with the rest of the tape removed by opposing presses down the paneling.

Radiator placement testing should be done on a per-case basis, not applied globally as a universal “X position is always better.” There are general trends that emerge, like front-mounted radiators generally resulting in lower CPU thermals for mesh-covered cases, but those do not persist to every case (see: In Win 303). The H500P is the first case for which we’ve gone out of the way to specifically explore radiator placement “optimization,” and we’ve also added in some best fan placement positions for the case. Radiator placement benchmarks the top versus front orientations, with push vs. pull setups tested in conjunction with Cooler Master’s 200mm fans.

Being that the selling point of the case is its 200mm fans – or one of the major ones, anyway – most of our configurations for both air and liquid attempt to utilize the fans. Some remove them, for academic reasons, but most keep the units mounted.

Our standard test bench will be listed below, but note that we are using the EVGA CLC 240 liquid cooler for radiator placement tests, rather than the MSI air cooler. The tests maximize the pump and fan RPMs, as we care only about the peak-to-peak delta in performance, not the noise levels. Noise levels are about 50-55dBA, roughly speaking, with this setup – not really tenable.

The Cooler Master MasterCase H500P is the newest in the modular MasterCase series, but is inspired by the old high airflow (“HAF”) line of cases, mainly in the form of monster 200mm intake fans and a general “rugged and futuristic design.” We covered the H500P along with the Cosmos series refresh C700P at Computex back in June, and now the time for reviewing has finally come.

Cooler Master’s H500P exhibited significant and plentiful quality control concerns, questionable design decisions, and limited semblance to the meaning behind “High Airflow” in the “HAF” naming. The case has its ups, too, primarily in the looks and cable management deparatments -- but we’ll go through all of that in this review. For Steve’s (rather animated) take on this case, check the video.

We first went hands-on with the C700P and H500P at Computex this year, and since then Cooler Master has been building excitement for their releases in a way that’s rare for enclosures. The C700P is one of the newest in the Cosmos line, which also recently added the Cosmos II 25th Anniversary Edition. Our initial review of the Cosmos C700P was conducted at PAX -- later renamed to "preview," because some struggling publications lamented the use of the words "initial review" -- and covered the case inversion process and other installation features. This is a follow-up to that, finalizing the thermal and acoustics analysis.

Cooler Master has revised their website since we mentioned the C700P in our Thermaltake View 71 TG review, correcting the its weight: it’s actually 49 pounds, not 58. The CM website had initially suggested the case would weigh 26.2kg but, after double-checking, we can say that the 22.2kg weight is accurate. Not that it’s a big difference, at that point.

For Steve’s take on the case, check the video below. The team’s written review of the case will continue after the specs listing.


Thermals and noise to align with final launch.

There were a lot of challenges going into this build: A lack of magnetism, a lack of lighting on the show floor of a convention center, and some surprises in between. Cooler Master allowed us to build in the brand-new Cosmos C700P case – a modular chassis with an invertible or rotatable motherboard tray – live at PAX West. After being faced with some challenges along the way, we recruited Cooler Master’s Wei Yang to turn it into a collaborative team build. It was one of the most fun builds we’ve done in a while, and the pressure of time meant that we were both taking turns dropping screws and reworking our aspects of the build. This was a real PC build. There were unplanned changes, parts that GN hasn’t used before, and sacrifices made along the way.

All said and done, the enclosure is exceptionally easy to work within: Every single panel can be removed with relative ease, so we were able to strip-down the case to barebones for the build. Our biggest timesink was asking to invert the motherboard tray to face the other side, since that’d add some flare to the build. This process isn’t intrinsically difficult, but it does require removal of a lot of screws – after all, the entire case can be flipped, and there are a lot of structural elements there. The motherboard tray detaches by removing 4-6 screws on the back-side, followed by six screws in the rear of the case, followed by a few more screws for the shrouds. We got some help for this process, as the case is one of the first working samples of the Cosmos C700P and there’s not yet a manual for which screws have to be removed.

This year’s Computex featured the usual mix of concept and prototype cases, some of which will never make it to market (or some which will be several thousand dollars, like the WinBot). We particularly liked the “Wheel of Star” mod at Cooler Master, the “Floating” from In Win, Level 20 from Thermaltake, and Concept Slate from Corsair – but none of those are really meant to be bought in large quantities. This round-up looks at the best cases of Computex that are in the category of being purchasable, keeping cost below $400. We’ll be looking primarily at ATX form factor cases, with one Micro-STX co-star, with a few “needs work” members in the mix.

This case round-up won’t include everything we saw at the show and will exclude the more exotic cases, like the Concept Slate and the In Win WinBot, but still has plenty to get through. Before getting started, here’s a list of the relevant coverage of individual products and booths that are discussed herein:

We stopped by the Cooler Master booth at Computex 2017 to take a look at two of their new iterations of previous Cooler Master cases: the HAF and the Cosmos ATX towers. The HAF, or High Airflow, cases were popular mid- and full-towers a few years ago, and CM will be bringing that back with their new Master Case H500P. The former Cosmos cases are also being refreshed for 2017 in the form of the new Cosmos C700P.

The Cooler Master H500P brings back the HAF series with dual 200mm RGB fans at the front for intake (included), and will provide less noise and more airflow than traditional 120mm or 140mm options. Static pressure is theoretically lower, but we’ll test all that in due time. Front intake is available through mesh on each side and the top and bottom of the curved acrylic front panel. The H500P comes with the two 200mm RGB fans included at the front but is capable of housing another three 140mm fans at the top -- above the top chamber -- or three 120mm fans within the lower chamber of the top panel. A 140mm radiator or fan mount is also present at the rear.

This week's news announcements include AMD AM4 Zen chipset naming (rumors, technically), NZXT's new RGB LED 'Aer' fans, and a pair of cases from Rosewill and Cooler Master.

AMD's initial AM4 chipset announcement was made at PAX, where the B350, A320, and XBA300 chipsets were announced for mainstream and low-end Gen 7 APUs. The high-end Zen chipset for Summit Ridge was concealed during this announcement, but is now known to be the X370 platform.

X370 will ship alongside the Summit Ridge CPUs and will add to the lanes available for high-speed IO devices, mostly SATA and new generation USB. Most of the IO with the Zen architecture will be piped through the CPU itself, with what remains of the chipset acting more as an IO controller than a full chipset.
