I'm not sure what RealTemp is, the AirFlow is on the warmish side but lets look at the CPU temp.
Here is mine just after startup... this AM.
It was actually a little higher when I first checked it as I had applied an update for .NET framework 3.5 and restarted. its nice here this morning room temp is 73F with 68F coming through the window.
CPU is 39C - 102F. with Max of 48C - 118F
The Airflow temp I think is the temp from the Samsung SSD.
Typically I will see my CPU be around 43-45C when mostly idle. Last week before Refreshing and Applying the 8/19 firmware is was having problem and was running about 10C hotter @ 55C idle.
When running an extended 20 minute CPU test with the new firmware my CPU stabilized at 71C with 100% utilization. during the early part of the test CPU temp hit 89C. That's about as high as CPU should go as Thermal Throttling will kick in at 89-90C to control heat.
So if you do nothing for 5 minutes and you're running 55C at idle I'd recommend doing a Refresh. Ambient temp does come into play and it would be good to know if your in a hot room.
If you had a temp shutdown while applying updates you definitely need to Refresh and take steps to avoid a temp shutdown while doing updates after the refresh. I can provide specifics if needed on that.
First things first though... lets us know your idle CPU temp and aprox room temp or normal range.
