Test Methodology

We tested using our Ivy Bridge test bench, detailed in the table below. This particular configuration has been retired and brought back into service, following some changes to our hardware availability. We’ve moved from a one-bench-fits-all setup (which uses a Haswell config in an mATX board) to multiple benches, one for mATX and small towers and one for ATX / mid-towers. This bench is for the latter.

Conducting thermal tests requires careful measurement of temperatures in the surrounding environment. We control for ambient by constantly measuring temperatures with thermocouples and laser readers. We then produce charts using a Delta T(emperature) over Ambient value. This value subtracts the thermo-logged ambient value from the measured diode temperatures, producing a delta report of thermals. AIDA64 is used for logging thermals of silicon components, including the GPU diode.

All case fans are manually configured to their maximum throughput using BIOS. If a fan controller is present, we opt-in and test on multiple settings. This forces testing of case fan performance in addition to the case's air channeling and airstream design. This also ensures minimal variance when testing, as automatically controlled fan speeds can reduce reliability of benchmarking. The CPU fan is set to use a custom fan curve that was devised in-house after a series of testing; setting the CPU fan to its maximum speed can limit the disparity shown from case-to-case as the CPU cooler is extremely efficient, and will create a ceiling for thermal performance if bottlenecked.

The video card is configured to run at 55% fan speed at all times. Stock clocks are used. We employ an NVIDIA GTX 980 reference for the case test bench.

Prior to load testing, we collect idle temperature results for ten minutes to determine the unloaded cooling performance of a case's fans and air channels. Thermal benchmarking is conducted for twenty minutes, a period we've determined sufficient for achieving equilibrium. The over-time data is aggregated and will occasionally be compiled into charts, if interesting or relevant. The equilibrium performance is averaged to create the below charts.

Load testing is conducted using Prime95 LFFTs and Kombustor “Titan Lake” stress testing simultaneously. Testing is completely automated using in-house scripting, and executes with perfect accuracy on every run.

Note: We retested the Corsair 600C ($150) following some configuration changes to our test environment. We've introduced additional measurement tools, so these results are not comparable to our previous benchmarks. The NZXT S340, Corsair 600C & 400C, Rosewill Gungnir, and Phanteks P400 were all freshly tested with our new instruments.

We recently validated our test methodology using a thermal chamber, finding our approach to be nearly perfectly accurate. Learn more here.

Rosewill Gungnir Thermals at Peak Load – P400 vs. NZXT S340, Corsair 400C

Rosewill's Gungnir is neither thermally impressive nor thermally offensive. It's marginally better than the P400 and marginally worse than some of these other cases.



Middle-of-the-road, as it were. Nothing exciting here. The Gungnir sits at 42.41C load for the CPU and 58.77C load for GPU thermals. If Rosewill modified their front panel with our suggestions, we're pretty confident that temperatures would plant the enclosure ahead of the S340 and potentially 400C – but then you're basically designing a completely new case, so that's not a great measurement.

A different representation of the data:



Conclusion: No Wishy-Washy Stuff


The case has a few good ideas, but none of them were seen through or fully developed. It just isn't there right now. The paint colors and exterior are mismatched and confusing, which is plainly just a massive ID and design oversight, and the interior is difficult to build with. Thermals are the only saving grace of this case – and it's not because they're impressive, but because they're simply adequate. Rosewill's three-fan approach does help offset its poor breathability.

We could sit here and waffle between the things they've done right and the things they've done wrong and get all wishy-washy about it to find a middle-ground, but the conclusion is simple: We wouldn't buy this case at $65. The competition is just too good. Maybe if it drops to $50, we'd consider it – but that market's fierce, too, with Corsair (100R - $55) and SilverStone (PS11B - $60) offering high-quality cases at that range.

If anyone at Rosewill is listening, we'd encourage you to dig through the archives and look at the R5 and what made that case so good, then try and iterate.

Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.'"

First world problems, Steve. First world problems.
