Fan on CPU and fan in power supply run full time. Third fan not running.Is it thermastaticly contrlled?
Depending on if the fan is plugged into only a molex (power) connector, or into a fan port on your motherboard, it could go either way. If it's plugged into the motherboard, there's a good chance the motherboard is controlling it thermostatically. A case fan venting out is always a great way to help improve airflow and keep components cool.
Hope this helps!
