i talt watercoolers were supposed to be more silent than air coolers lol.
not exactly, water coolers liek air coolers need fans, and fans generate noise as well but watercooling also has a pump which can make noise. the main thing seperating water cooling and air cooling is watercooling looks for fans with high static pressure to low noise and air coolers usually like air flow to noise ratio. What makes watercooling slightly different is that the heat is dissapated away from the cpu while air coolers is on the cpu. You can have a noisy watercooling unit if you tried.
edit: if you own an oem case, neither of the stated coolers will probably fit. oem cases lack fan holes at key locations, and lacks size to fit big AIOs. the most you can fit are lower end ones or lower profile ones generally.
