Non-illuminated CPU fans, also known as plain or standard CPU fans, focus solely on the crucial task of cooling the CPU without the added frills of RGB lighting. These fans are designed with simplicity and efficiency in mind. They are typically made of durable materials such as high-quality plastics and metal alloys for the fan blades and housing. The blade design is engineered to optimize airflow and static pressure.

The main advantage of non-illuminated CPU fans is their reliability and cost-effectiveness. They are often more affordable than their RGB counterparts, making them a popular choice for budget-conscious computer builders or those who prioritize performance over aesthetics. These fans are widely available in various sizes and specifications to fit different computer cases and CPU sockets. For example, a common 120mm non-illuminated fan can provide sufficient airflow for a mid-range CPU, while larger 140mm or 200mm fans are suitable for more powerful processors or cases with better airflow requirements.

Since they don't have RGB lighting, they also consume less power  which can be beneficial for systems where power efficiency is a concern. Additionally, non-illuminated CPU fans are generally less likely to experience issues related to lighting failures or software compatibility problems that can sometimes occur with RGB fans. Their straightforward design makes them easy to install and maintain.  non-illuminated CPU fans are a practical and dependable option for keeping the CPU cool and ensuring the stable operation of a computer system.
