I would not rely on web reviewers who "look at something" and say "air flow sucks". If they don't use instruments or at least a fog machine (or swap out the fans for useless hi speed varieties), I'd recommend not paying attention. Especially the hordes of cases that they decide "by visual examination" have great air flow with 3 fan mounts on top that folks use as exhaust such that all the air exiting the 250 watt GFX card and 750 watt power supply is being sucked right back in thru the rear case grilles. Grab a $39 fog machine from Chauvet n amazon and you can see this clearly. The EvolvX air flow is just fine.
f your inlet filters are clean, you'll need at least 1.33 times more intakes than exhaust ... as they get dirty, move that up to 1.5. and of course rad fans always blow in, no exceptions. If you keep the included Phanteks fans (adding more recommended) sound levels should not be audible even with your GFX card and CPU. I agree, sound deadening material does its job, but I have yet to run into an instance where the case made an audible noise without it.
I can't say a bad thing about any Phanteks case ... I don't think there's been more than 1 year where they didn't come home with the "Case of the Year" award from Computex since they opened their doors. The canucks video shows the 600S features work .. their magnitude however is not all that big; however in their own words, the test is "unscientific" ... and they had the side panel off while testing which essentially puts a hurt on the validity of the test results. I addition that instrument itself blocks air flow.
So lets look at what the advanced air flow features on the 600S provide.
Front Panel On = 271 fpm
Front Panel Open (angled) = 281 (+3.6% air flow)
Front Panel Removed = 281 (0 Gain)
Front l Mesh Removed = 300
Air Filters Removed = 313 (not recommended)
His test did however do one thing ... the600S which is based upon the allegedly air restricted Evolv gained just 3.6% by completely removing the panel . The conclusions with regard to the Evolv's air restriction were clearly not all they were cracked up to be. Given this test result, that assumption has been disproved once and for all. I hope they eventually come out with a v2 that affects the expressed finish and other aesthetic concerns in the previously referenced review. There's a new Enthoo Luxe v2 coming out that has already piqued my interest.
So, aafter significant thought on how to improve things, while the performance improvement is notable (and I like that they "went there" and hope continue the direction), taking off the front panel gave only 3.6%. As good as every other Phanteks case has been, I don't see the improvements, are going to have a great impact on interior case temps. We have two air temp sensors (ambient and interior case) and 4 water temp sensors (one in and one out for each rad) in our test box. Typical case interior temps run 2 - 5C above ambient depending on how many fans (3 - 16) are plugged in. Looking at ths 3.6% improvement, that would mean from 2 to 5C to 1.93 to 4.83 delta instead.
Of course aesthetics is a very personal thing and while it's been said that some Phanteks cases should be in an art museum, this is not one of them, at least not yet. Like the linked reviewer I personally don't like the colors and finish on these cases. The matte steel finish makes it **look like** cheap plastic even tho the panels are very rigid and well made/
I'm not sure why you can't find reviews, I linked to 2 and I saw several more.... of course since not retail at this point, they are somewhat limited as yet . Of course many are silly ... below the "reviewer" determined it was high air flow "because the guy at the show said so"

But Canucks was informative , that link in previous post ... Paul did a decent look ... tho not exactly "deep"

The last one with the gray case and MSI black / gray components was very attractive ..
We have had most Phanteks cases here ... Im typing from a Primo with 16 fans that if you close your eyes you can't tell it's on. I have tested the Primo, Luxe, Pro and original Evolv and they did just fine in fog machine testing, and most of those builds had twin GFX cards ... inaudible and great temps. Air turn over, all fan mounts occupied, with low speed fans is usually more than twice per second up at higher rpms (and by higher I mean upper third of 1200 rpm fan range) and never less than once per second. As I type here, on the Primo, no fans are spinning. But if ya wait a bit, I'm sure we are going to see someone do a side by side comparison with the Evolv and 600S. With all panels in place, we should be able to measure just what the sound deadening and sound improvements are.
