Acoustic Performance Test Procedures:
- We placed our Digital Sound Level Meter one metre away from the front of the case.
- Only the case fans and our power supply are active to accurately isolate the acoustic performance of the case fans.
- The case fans are set to maximum speed (connected to the 12V molex connectors of our PSU).
- The Cougar Challenger‘s default fan configuration is 1x 200mm front intake fan and 1x 120mm rear exhaust fan.
Please refer to our KitGuru noise guide for a comparison between the noise levels of this case and everyday scenarios.

Acoustic levels for the Challenger are average. A 40.1 dbA noise output isn’t bad, but an inexpensive fan controller would have helped reduce the acoustic value.
