Although, I don’t have custom water cooling in my pc, I am just curious, apart from lower overall temperature, is there a reason you want to go custom?
As for your questions. I already have a custom watercooled PC. I just wanted to have knowledge of websites where I can get these parts in Inida, cuz you never know with PC components when you need one.
As for why whould you go for one? I neccesarily dont agree with the overall lower temp misnomer.
Your temps depends mostly on the amount of Radiator and the speed of the fans you are running.
As for me going with full loop was because I wanted a bit more complexity while building and lower noise. With the added benift of temp control, becuase thats what you mostly get from watercooling.
