Questions regarding lenovo legion 5i gen 7

Hi I bought a legion 5i gen 7 with the following specs...

15 inch 1440p screen Core i5 12th gen Rtx 3060 16gb Ram 512gb ssd 1080p Fhd webcam

I added a 1tb samsung 980 pro to the second ssd slot and thats about it.

But now i wanna upgrade the ram the existing ram bus speed is 4800mhz ddr5 but i want to add about 32gb (2x16) that has 5600mhz or even more (6000-7200mhz)

Could it cause any problems for my laptop?

And secondly how do u guys keep ur laptop clean?

Like the whole thing screen and overall body...i live in a tropical south east asian country with a very hot humid weather. Finally what is the process of windows 11 cloning?
