Does spread spectrum clocking cause a CPU to operate at higher temperatures? If so, why?
Spread spectrum clocking minutely varies a CPU's clock speed to spread out RFI to meet FCC and EU guidelines.
I disabled spread spectrum in my BIOS, and my CPU is running ~20°C cooler!
I also noticed that disabling spread spectrum sped up my computer. According to luminaris on Tom's Hardware forum, "enabling spread sprectrum actually hurts performance". Why is this?
