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 Core2 Extreme/ Core2 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 10C up from 70C will reduce CPU life time for about 1 year (Source: Intel)
Every 10C up from 120C will reduce VR life time for about 50%
Temperature over 100C will cause Capacitors leakage or burned abnormally
Thats why a good thermal solution makes system more stable and extends components life.
