Optimized Airflow with 3x 120mm ARGB Fans
Airflow is a priority in the Cooler Master Elite 302. A large front intake grill works together with three pre installed 120mm ARGB fans to ensure steady cooling for your CPU and GPU.

• Rear: 120mm radiator

This range of cooling options makes the Elite 302 suitable for both entry level air cooled systems and more advanced liquid cooled builds.

• CPU cooler height: up to 163.5mm
• Graphics card length: up to 365mm (without front fans and radiator)

This combination supports fast data transfers, modern peripherals, and easy headset connectivity without reaching behind the case.

Clean Build Design with Practical Details

Dust filters at the top, bottom, and front help keep internal components cleaner over time, reducing maintenance and improving long term reliability.
