Will running 2 Dell UltraSharp 27 4K U2723QE on my 2020 MB Air (Intel) slow it or run hot?

[questionwonder]

According to Apple I can plug 2 4K displays into my Macbook Air 2020 (Intel).
What's the best way to set up 2 Dell u2723qe monitors?
Will using 2 of these new displays slow my MB Air 2020 down because of all the pixels?
Would I plug 1 into each port, can I daisy chain 1 display to the other and plug just 1 cable into my Air, or get some kind of Thunderbolt adapter or something?
I just want the best quality from each display.

I used to plug a Dell U2718Q into my old MBP 2018 15 i7, it got to 60-70 celsius without any task running.
