So I got a Cooler Master Seidon 120V today and successfully overclocked my Phenom II X4 980BE to 4.1 GHz apparently stable so far and the CPU temperatures are under control. I have an Asus M5A97 R2.0 motherboard. When I touch the VRM heatsink, it feels like 75 degree C while running prime 95 in small FFT mode, max heat and power consumption. Is it ok to keep this overclock 24/7? Or should I consider cooling the VRM additionally?
