Benchmark Results & Conclusion

Normally we would compare the performance of the Quadstellar to other chassis of similar sizes and feature sets but, as you can tell by now, there really isn't anything else on the market close to this chassis in features and design. That said, we are using the NZXT H700i, the Bitfenix Enso, and the be quiet! Dark Base 700 for comparison because they are all premium chassis. All thermal tests were performed with the front active thermal control gates closed to simulate a "worst case scenario."

Due to the Quadstellar's severe CPU cooler height limitation, we were unable to use the Cooler Master Hyper T4 normally used in our standardized test configuration. We chose the low profile Noctua NH-L12 with a single 120mm fan attached for testing. With that in mind, let's take a look at thermal performance.

With case fans set to 1400 RPM for testing, CPU core temperatures on our budget quad-core Core i5-7500 processor running at 3.8GHz were easily the best we have ever seen. This, despite the fact we used a smaller, low-profile CPU cooler. Even under 100% load, processor temps never exceeded 35°C over the ambient temperature of 25°C. GPU temps were taken with the graphics card installed in the upper right hand lobe of the chassis. The close proximity and position of the dedicated 120mm intake fan kept GPU temps to a minimum during testing. We attribute the Quadstellar's phenomenal CPU and GPU temps to its unique compartmentalized wind tunnel design.

We tested the Quadstellar with the front doors open to allow as much noise as possible to escape the chassis to give you an overall idea of just how much noise this case generates under the most extreme conditions. We were suprised to find that, even with the active thermal control doors open, this chassis produced only 33.9dBA. This is most likely due to the combination of the chassis' thick metal casing, tempered glass side panels and the accoustic profile of the fans themselves.

We determine acoustic efficiency, also referred to as "cooling-to-noise ratio," by averaging all five of our tests to determine a base value.

This is the point in the review where we tell you that our value chart doesn’t take features into account. That's because, even though this chassis has great thermal and acoustic performance, it is hard to justify the $400 price tag based on performance alone. This is where the Quadstellar's list of features, unique looks and impressive design come into play. Those of you looking for a chassis that will impress friends, colleagues and bystanders alike right out of the box, would be hard-pressed to find a better chassis, even at this price point.

We are fully aware that looks are subjective, but we think it is relatively safe to say that there are very few cases on the market today that have the "wow-factor" of Deepcool's Quadstellar chassis. We are the first to admit that this chassis may not be for everyone but, to be fair, Deepcool isn't targeting just "everyone." This is a specialized high-end chassis with a unique design that is sure to impress.

    That is COOL. No doubt massive, but a very neat case.
  • redgarl
    I love the GPU and PSU compartment idea, I can't agree with the design and the price. Now only if Fractal or Phantek could incorporate these feats in one of their offering, that would be interesting.
  • BulkZerker
    No USB Type-C port
    Disappointing, really expect this from something at this price point.
    No manual controls (app only)
    Absolutely ruined.
  • Karl_in_Chicago
    $400 and no USB-C? Sigh.
  • mlee 2500
    Hideous and Pointless.

    Why do you need 9 3,5" hdd slots? This is the era of pcie -SSD, m.2 and 2,5" form factor.

    Nice case but I think that the acoustic efficiency chart is wrong, unfair and unrealistic. You can't take 2 extreme scenarios that would never co-exist at the same time and create an acoustic efficiency chart. There is no way you can compare the temps of a closed doors case with the noise of an open door case. If you want to have the temps of a closed doors case you have to show the noise levels of a closed doors case and vice versa. Otherwise that chart has no meaning at all. Thanks.

    would have been nice if some of the pics of the case weren't close-ups. can't see what's going on.
  • Lasselundberg
    reminds me of the Ghost from Destiny2...i really like the case...but lack of usb C bugs me...would like to see more USB ports in biggest issue is the width of this thing...i would buy it in a heartbeat, but i dont have that kind of space next to my table

    Moving the PSU into its own compartment with its own helper fan and thus thermally isolate it from the other components is a great idea. It works extremely well in my hot climate and my Air 240 case with 4 auxiliary fans, 1080 and water cpu cooler keeps things at max 64 celsius when gaming. Idle is 32 Celsius and with a 1700x everything else is Idle. Many bays. Power density and cooling is very high with this case. It reminds of 1970 Mini Crays, which were 20 bigger and 10 000x slower. Its kind of humourous in a way.

    This dp case is style over function and I like that mfg experiment. Dis case implies functionality where there is none - its akin to a 56 Eldorado :-). Nice, there is definitely space for non mainstream cases and mfg should explore concepts. No USB C is no go. Additonal cables will add failure points. The weight of this thing means it will deform over time when moved over time. Its a tin frame...and its senslessly big. A product for the affluence compromised youth living in a McMansion and held at an emotional distance by their parents with a Mastercard...and it does cure bad skin :-)
