if hes getting them from amazon they normaly give you a 2 week gap to return items back
prity much all ram manufacturers have a life time warrenty so if they end up being defective he should be able to get replacement cards from the manufacturer

all am4 boards had issuses at launch they all mainly fixed now with bios updates its not just msi boards

all the info i can find on them fans are all high static pressure and they are perfect for radiator mounts so you should be good to use them
