Question about be quiet! MC1

I have a HP Omen 45 l which has a 2 terabyte m2 Western digital drive. I have a HP Omen 45 l which has a Western digital m2 of 2 tera I would like to buy a second M2 tera but my knowledge is limited. I'm looking for a second M2 tera, but my knowledge is limited. I'm looking for a very large radiator on the original one, which I haven't found in Switzerland yet. It is marked on the motherboard for the second slot heat sink required so in your opinion is it possible to buy the one https://www.digitec.ch/fr/s1/product/wd-black-sn850x-2000-go-m2-2280-ssd-21635316 and add this heat sink which I suppose is compatible or another heat sink that you can advise me or then I put the one https://www.digitec.ch/fr/s1/product/wd-black-sn850-with-heatsink-fuer-ps5-2000-go-m2-2280-ssd-21477797 without anything? of the remainder for the latter can we add a heatsink in addition is it possible and is it useful to something? As you can see my knowledge of m2 is limited, thank you in advance for your precious and efficient help from the community as often
