What should one do with water cool gpu mosfet?

From what I have heard, it is mostly for show. The temps can get pretty hot many times, but those components are just made to be get hot. The only reason I can see going is if you have a fan on your north bridge that is just too loud or if your ocd and have to have all your temps as low as possible.

First and foremost, why put your PC under water? (No, not literally).

the reason behind it is better temperatures, higher clocks, quieter running system,good looks, impress the ladies, if you are a lady, really impress the guys etc.

Whatever your motivation, you just have come to the right place and at the right time. You have to accomplish all for this and then some.

Before you jump into water cooling, it’s always best to just plan your water loop, from start point to finish point. By this, you have to ground up, starting with the most basic components.
