My original P4 was manufactured May 2016, and I purchased it from DJI in Sept 2016. I had to return it to DJI in May 2017 due to VPS errors, and they sent me what appears to be a new P4 under warranty, and the manufacture date of the new P4 is Jan 2017. I say new, because nowhere on the box did it say 'refurbished', and the S/N does not indicate that it is a refurbished unit.
On my original P4, when I started it and left it running for any amount of time - with motors off, such as an IMU calibration - I noticed that the cooling fan would occasionally increase its RPM, presumably to maintain a certain temperature. My new P4 does not do this, but rather, the fan maintains a constant RPM that is about the speed of the original P4's fan when it was running at its slower speed.
I have had it out on fairly hot days, and I have never gotten any warnings about it overheating, so I'm wondering if this is just simply due to a slight change in design.
Has anybody else noticed this?
