Connection of case fans to the B660M motherboard
Hi, I have a Corsair 4000D Airflow case paired with a B660M motherboard. It seems the SYSFAN connections on the board are four-pin, but my two default fans only have three pins. Please let me know if you need guidance on the right connection method!
Connect three fans using a 4-pin connector. Switch the fan settings to DC mode in the BIOS. The 4-pin unit manages power delivery, while the 3-pin setting controls speed. Power output varies depending on the pin configuration.
Only 48°C is quite normal for a CPU. When it's idle with no tasks running, it tends to get slightly warm, which varies based on the processor and cooling solution.
