Test results noise production
Noise production is the flipside of the cooling coin. We test noise production in a soundproof box, in which all sounds above 17 dB(A) can be detected. Standard ambient noise levels are around 30 dB(A). In the chassis we put a Scythe Mugen 2 CPU cooler, a Scythe Gouriki 700W and an old Hitachi 80GB 7200 RPM hard disk. We test each chassis without any case fans running, to test the dampening potential. The charts on this page only show the total noise production with fans on low (7V) and high (12V).
In this test we see the power of the Bitfenix Shinobi XL. At full speed its fans are the most silent in its category.
With fans on low the Shinobi XL doesn't really stand out. Its 36.1 dB is not particularly loud, but it could be quieter. We suspect that the 120 mm is the culprit here.
With the fans running at high speed, the results are radically different. The Shinobi XL is one of the quietest cases if you also want serious cooling. The Spire Epoxi cools significantly worse, which you can see in the chart on the previous page.
