Notes:

Start by using the fast speed (3000RPM) for about 15 minutes and as the temperature drop downs, change to the minimum fan speed (1500RPM) so that the working temperature remains constant. This will prolong the service life and lower the noise. Due to the light and screen setting differences, the item's colour may be slightly different from the pictures. Please allow slight dimension differences due manual measurement.
