Circling back now I have been running the Pi 4 for two weeks.  With regard 
to hear this article has a good write up and I agree in general: 
https://www.jeffgeerling.com/blog/2019/raspberry-pi-4-needs-fan-heres-why-and-how-you-can-add-one

But for weather users I have found the is a more heat significant issue if 
you use an RTL-SDR to listen to the weather stations's RF.  I found that 
both the USB ports and RTL-SDR itself on the 4 become uncomfortably hot to 
the touch and the CPU will report about 60C or so--no enclosure.  Perhaps 
overly cautious, but I did not let it run unattended so maybe 6-8 hours at 
that measure point.

Adding heat sinks to the RTL-SDR (I had a pair of 7mm and a pair of 14mm I 
attached) and a fan keeps me around 50C (49-51C) with an ambient 
temperature of 78F.  I do not have the case yet so the fan is clamped 
(positioned) just inside of the usb ports so that it blows towards them 
(out) and over the RTL-SDR.  

Temperature has been stable; but waiting for the case makers to catch up 
and accommodate a touch screen. 

Cheers,

Jack
