ASUS Silent Knight II

Excellent Performance for Overclockers
100% copper materials and six copper heat pipes ensure excellent heat dissipation for maximum cooling performance

Universal Application
The Silent Knight II supports the Intel® Core™2 Extreme/ Core™2 Quad (Quad-Core) CPU, Intel® Pentium® 4 LGA775 & AMD Athlon™ 64 X2 Dual-Core CPU, AMD Athlon™ 64(-FX) (939/940/AM2)

Best Balance between Performance and Acoustic
PWM function automatically adjusts rotation speed according to CPU temperature and delivers a quiet cooling at a mere 25dBA

Reliable
The fan positioned inside the frame and VRM shield guides cool air to critical components around the CPU for stable operation

Why Thermal Matter
Every 10°C up from 70°C will reduce CPU life time for about 1 year (Source: Intel)
Every 10°C up from 120°C will reduce VR life time for about 50%
Temperature over 100°C will cause Capacitors leakage or burned abnormally
That´s why a good thermal solution makes system more stable and extends components´ life.
