Hybrid Fan Pin Headers
Assume complete control over your liquid cooling setup! Smart Fan 5 receives
up-to-the-second information
on flow-rate and water-temperature through the Hybrid Fan Pin Headers or external
thermistor sensors—giving
you absolute mastery over your PC.
• All Hybrid Fan Headers can automatically detect the type of cooling device
whether it be fan or
pump with different PWM or Voltage mode.
