Acoustic Performance Test Procedures:

• We placed our Digital Sound Level Meter one metre away from the case.
• The case fans are set to maximum speed.
• The CPU cooler’s fans are deactivated.
• The Thermaltake Chaser A31‘s default fan configuration is: 1x 120mm front intake, 1x 120mm rear exhaust.

Please refer to our KitGuru noise guide for a comparison between the noise levels of this case and everyday scenarios.

Thermaltake's 1,000 rpm, 120mm fans exhibit very good acoustic performance levels. Even at 100%, we would have no problem sitting next to the Thermaltake Chaser A31 all day long without becoming irritated by its noise output.

Lacking a fan controller or any type of hub, as soon as additional units are added to the chassis and a motherboard's speed-variable fan headers are saturated, noise output is likely to increase rapidly due to the fact that certain fans will be glued to 100% speed.
