Subject : 
VM6404H fan activate temperature
 
Description : 
After I upgrade the firmware of VM6404H to v3.4.334, the fan on VM6404H doesn't activate even the temperature is 59 degree.
Does the fan activate temperature change? 
 
Solution : 
The firmware v3.4.334 changes the fan activate behavior, because some customer complain about the fan noise.
When the temperature is equal or over 78 degree, fan will be activated with high speed.
After the temperature is 10 degree lower(lower than 68 degree), fan will stop.
