Well Liquid Cooling is super effective for over clocking like you said, but it is definitely more maintenance and a faulty or damaged tube can cause a ton of issues. So the way i look at it is: Liquid is good if you are confident enough to keep up with the maintenance. On the other side, you could buy a Noctua NH-D15 if you want a beefy air cooler. They have been known to be just as effective as liquid cooling for temperatures even while overclocking. That option would also require less maintenance and you wouldn't have to worry about destroying your MoBo with a leak.
