I noticed today when i turned on my computer, there is a dramatic increase in fan speed, While playing the same games. World of warcraft/LEague of legends.
It goes to about, Temperture: 54C Fan speed 86% Fan speed 34%
It's really loud. Does anybody know why?
Or is this normal?

Consider enabling QFan control in the BIOS if not already enabled, or install the ASUS fan utility to enable Cool 'n' Quiet.
