If I change XYZ fan to a SilenX one will there be sufficient cooling?
A, Sufficient cooling (for a standard heatsink + fan setup) basically means your setup can dissipate sufficient heat to keep your components at a safe operating temperature. This is a combination of how well your heatsink radiates the heat and how well that heat is carried away by the surrounding air. SilenX fans have an excellent noise to airflow ratio so even though they spin at a lower RPM in most cases the increased efficiency is enough to maintain sufficient cooling.
