Fan Xpert 4
Fan Xpert 4 provides customizable fan settings for a cooler and quieter computing
environment. With its Auto Tuning feature, Fan Xpert 4 automatically tweaks the settings
of the CPU and chassis fans to achieve their best cooling performance. Fan Xpert 4 also
supports hardware level PWM/DC combo mode for the CPU, chassis fans, and fans
connected to the fan extension card. You can also reduce the CPU fan speed below the
default minimum for a noiseless operation during light loads.
• DO NOT remove your fan during the tuning process.
• To prevent the water pump from not working properly due to different water pump
manufacturers, the water pump header does not support the Fan Tuning function.
• When the CPU temperature reaches 75
o
C, the fan will automatically run at full speed
to protect the CPU from overheating.
• If your fan is installed with an external control kit for rotation speed control,
Fan Xpert 4 may not be able to detect the fan speed correctly.
• Fan Xpert 4 does not support 2-pin fans. If you have installed a 2-pin fan, it will only
run at its full speed.
• If the CPU or chassis fans have been changed, the Fan Tuning process should be
performed again.
