Do all 4k and 5k screens have fans in them

you can't compare a wacom screen, processor or no processor to a regular display. no other regular displays have fans in them.
Except the UltraFine 5K, which has a fan... although I guess that isn't exactly a regular display.
You are all over the place with the terminology which makes it very difficult to understand what you are meaning and thus give a proper answer to your question.
As stated above all regular 4k displays do not come with a fan. There aren't any regular 5k displays because the current models all require some tricks (such as 2 DisplayPort connections) to work. The 5k display from LG is not a regular display as it is a Thunderbolt 3 display sporting USB, webcam, speakers, etc. which is also capable of charging the 15" MBP at 87W (none of the others do). No review speaks of a fan in this display though (although it wouldn't surprise me if it had any considering its features, especially the in-built 87W charger).
If you want an example of a 4k display then look around in the accessory subforum here, there are quite some threads for several 4k displays.
