Key Components

At the heart of this gaming PC is a Ryzen 7 9700X CPU, cooled by the ID-Cooling IS-55. To ensure smooth operation, the critical temperature for both the CPU and housing fan is set at 95 degrees Celsius. The housing fan temperature limit is set to 55 degrees Celsius with a fan duty of 10%, while the CPU fan temperature limit is set to 55 degrees Celsius with a fan duty of 30%.

The system is equipped with 2 x 16GB Crucial DIMM Kit DDR5-5600 RAM, providing ample memory for even the most demanding games. The storage solution comprises a Samsung SSD 990 Evo Plus, 2TB, ensuring quick load times and smooth gameplay.

Advanced Settings and BIOS Configuration
