Ah ok, thanks

is there a easy way to explain water cooling to me? If it's to much hassle you don't have to.
The two types you'll see are going to be AIO systems (all in one) that are sealed setups that you buy, install and just let run. Same sort of maintenance as an air cooler in that you just need to clean out the dust every now and then. The bigger liquid cooled systems are full custom setups, that you have to individually buy components, and are considerably more labor intensive.
For most people and AIO is fine, and in some cases is better for a system depending on form factor, as large air coolers can interfere with other components, usually those being RAM modules
