Odd fan behavior, temp climbing

Rolled out a brand new 12-250 AC it is weird that the fan revs up and then stops and then revs up and stops. I'm a little worried about the temperature as it is much higher than the other twin I have to compare it with, its twin is also holding fan steady at 2500 rpms

its just the coming netflix rush at a mountaintop site, nothing to worry about right ?

2500 RPM is a thing of the past, not to be seen again on newer firmware.

Good to know, sure seems odd though and the temp looks high, cpu seems to have levelled at 84C

You NEED to install v1.5.2rc5 for proper fan control.

Please upgrade to v1.5.2rc5

SUNON changed their fans and the new software is needed to properly drive them.
