The E9 580W follows a traditional Be Quiet! design, which is both attractive and immediately recognisable.

Taking centerstage is a 135mm SilentWings fan. This is a fluid bearing fan to offer a high life rating of 300,000 hours. The fan blade surface is flow optimised to give higher CFM at lower speeds while keeping noise to a minimum. The fan grille design and mounted are also carefully designed to lower noise emissions.

The power supply is fully vented to for maximum airflow. There is a power connector and power button at the side.

The sides of the chassis are subtlety engraved with the name of the company.

The modular cabling management system is clearly labelled and colour coded to aid with the system build phase.
