That depends. I'm going to assume that you're going to use an All in One cooler (AIO) instead of creating a fancy custom loop.
IMO the act of physically installing an AIO is physically easier than an air cooler since waterblocks are easier to manhandle than enormous heatsinks, but there is a longer checklist of details with an AIO that you want to check.
>Make sure that the radiator will fit
This sounds simple, but it's embarassing if you fuck it up. Bigger radiators are better at cooling. The case should have documentation about what it supports.
>Orient the radiator properly
Just follow that picture that I posted in the last message.
>read the fucking manual before you start
Before you install the processor, you should familiarize yourself with how the radiator will attach to the case before you install anything. Practice mounting the radiator before you commit to the full installation.
Once you're mounting everything for real, it's easier to start with the waterblock first and then mount the radiator. Have a friend hold the radiator nearby to relieve tension on the tubes while you're screwing the waterblock in.
>before you install everything, make sure that the fans are pointed the right way
Just double check.
>be careful which motherboard headers that you plug the wires into
READ THE FUCKING MANUAL for both the cooler and case. Modern mobos have a specific header for waterblocks. The fans go into a fan header. The distinciton is that waterblocks want to run at full speed 24/7, but fans ramp up or down in intensity depending on how hot things are going. So just make sure that you don't go plugging the waterblock's pump into a fan header. With older hardware you'll probably have an adapter to just plug it into a wire coming off of the power supply so that it's simply ON 24/7.
Also, while we call it "water" cooling, these AIOs don't use water. The coolant is non-conductive. Leaks are a mess but the electronics won't fry.
