It depends on your specific setup and the compatibility of your case fans with the CPU fan headers on your motherboard. Make sure the fans match in terms of pin configuration and voltage requirements. Always check the manufacturer's guidelines before making changes.
As long as the fans match the headers, they should function properly. The issues to consider are: 1. When the system boots, the CPU fan connectors are verified to confirm cooling capability; if a case fan is connected, this verification becomes irrelevant. Also, any monitoring tools will display the case fan status as if it were a CPU fan. Keep this in mind during troubleshooting. 2. With variable speed fans (4-pin, PWM), their rotation is controlled by the computer, mimicking a CPU cooler. If your CPU gets hot, increasing fan speed helps. This is beneficial only when the fans adjust based on CPU temperature and the CPU stays cool—otherwise, problems arise if GPU tasks cause heat despite reduced airflow. Such scenarios can occur with less CPU-demand games or when performing GPU-only work like rendering, mining, etc.
The main problem is that your computer assumes it has CPU fans when it doesn't, which can cause confusion if the cooler stops working or if you're unsure whether the fans are actually for the CPU. This issue becomes more noticeable during troubleshooting.
