Actually I can't think of an advantage for the H80....
1. It doesn't cool as well as the top air coolers. H100 wind by a little
2. They are 19dBA louder than the top air coolers according to Corsair's advertising..... with each 3 dBA representing a doubling of sound pressure level, 19/3 = 6.333 ..... 2^ 6.33 power means it's 80 times louder than a Phanteks.
3.. You can make it quieter buy changing the fans, but then it loses cooling capacity w/o the high rpm fans.
4. Given the above lack of benefits, why add water inside ya substantial cash investment ?
I recommmend two options:
A. Top end air cooler ....see top 3 here:
