ASUS Q-Fan Smart Cooling System Enables Quieter and More Efficient
With the Q-Fan cooling system, users can now work in a distraction-free
environment with minimal system noise. This unique technology,
which intelligently and automatically adjusts CPU fan speeds
according to system load and temperature, is available only
on motherboards by ASUS, the world's top designer and manufacturer
CPU cooling fans are the number one cause of noisy systems.
Incorporating an ASUS-developed ASIC (application specific
integrated circuit), which monitors CPU temperature and adjusts
fan speed, the Q-Fan technology automatically lowers fan speed
when CPU temperature decreased due to lighter system load,
ensuring a quiet computing environment. And of course, when
system load increases CPU temperature, the Q-Fan also intelligently
pumps up fan speed for cool and stable system performance.
Hence, the cooling fan is not constantly running at top speed,
prolonging the life cycle of your cooling fan while conserving
The table below illustrates the Q-Fan's advantage over existing
fan solutions. Fan speed of conventional motherboard fan technology
remains the same even when system load is minimal. As you
can see, when temperature is under 50¢FJ, Q-Fan automatically
lowers fan speed. However, when temperature exceeds the 50¢FJ
threshold, Q-Fan will increase speed for more efficient cooling.
