Apart from the Pi4, to upgrade, I know that I will need a bigger power supply and a HDMI adapter lead, but after, things are a bit vague.  Can I get away with the Pi4 without any additional cooling, or do I need a heat sink or fan, and if so, how do they get on with the hat ?  The space it is in has had a temperature range of -1 to 40 degrees C, the mean across that time is about 15.5C.

40C is quite a high ambient temperature. If you are going to run the Pi 4B hard with the likes of matplotlib, passive cooling my not be enough to stop it throttling. One of mine has a large heat sink case with no fan and never goes over 60C, but that's at a 20C ambient. For 40C ambient, I would recommend a fan case, go for a 40mm fan if you want it to be quiet, 30mm ones can be noisy.

40 was probably a one off (heat wave), but mid 30s occur every summer month.
I've been looking at fan cases, but they all seem to prevent the use of the HAT, which means I won't be able to find out what the ambient temperature is.  I suppose I could design one of my own.
