Is the H100i a water cooler?

[thelolster32]

So I found this cooler that I was supposed to pair with an i7-7700k which does not have a cooler. Then I head to Corsairs website and saw that it's a water cooler. Then I saw a guide that Corsair linked to their page about the said cooler. In the guide there is no water used, there's even pics in the step by step.

The guide is here:

there is a liquid within this cooler that flows in the cooler and transfers the heat from the CPU to the radiator where the liquid is cooled.

Oh so another question.

Im going to replace that H100i with an H80i, will the H80i fit with an Aero-500 with window Case here https://www.aerocool.com.tw/en/chssis/pgs-a/aero-500.

Edit: Can the H80i also fit in the Aero-300 here: https://www.aerocool.com.tw/en/chssis/pgs-a/aero300

Thank you
