SilverStone’s Aero Slots, evolved from the vented slots first utilized in the prestigious Temjin TJ10 performance tower chassis, are designed with optimal venting ratio to increase airflow efficiency without negatively affecting EMI (Electromagnetic Interference) emission. Finished with beautiful black Nickel–coated or painted surface, the Aero Slots can add greatly to the aesthetic appearance of any case while improving cooling performance when used with hi-end graphic cards or hot-running expansion cards.
