The SilverStone Kublai 07 (a.k.a. the SST-KL07B, in keeping with SilverStone’s difficult-to-Google naming conventions), is a relatively inexpensive competitor in the silent mid-tower category typically occupied by Fractal and Be Quiet! Cases.
Today, the SilverStone Kublai KL07 is on the bench for review versus the Fractal Define C, Be Quiet! Pure Base 600, NZXT S340 Elite, and several other recent case launches. We’ll be looking at noise and thermals primarily, with some additional focus on ease-of-installation and build quality.
This content is basically just a video, since we can't very well convey noise through words. Except maybe by YELLING with CAPS. We produced a similar type of video for the RX 480, basically comparing fan noise levels by recording them (using the same level of input each time on an X/Y H6N mic), then playing them back. Fans were tested at idle, 50%, and 100% for this comparison. The GTX 1060, RX 480, GTX 1070, and MSI GTX 1060 Gaming X are included in this video.
Anyone who's already seen our exhaustive RX 480 review & benchmark is likely aware of our new noise testing and fan speed vs. time/frequency plots. The video was embedded in that review, but it's worth discussing in greater depth.
The test is a mix of subjective and objective noise analysis. The decibel testing was conducted prior to getting on camera, with a different setup than is shown, but we moved the bench for demonstration purposes (into the video set). Our noise testing methodology is detailed further below. As for the subjective testing – that's the new part.
Subjective noise analysis of cards is important, as our raw decibel output values do not tell the full story (and we don't presently have a good, data-hardened way to plot frequency spectrum analysis). Two fans that operate at 50dB may have completely different noises. One fan might be high pitch in nature – or maybe it's got a high pitched whine accompanying the normal low-frequency whirring – while another fan is low pitch. Depending on the user, the lower pitch fan (despite being equally loud in dB output) will likely be more bearable than an incessant whine.
