I've decided to upgrade a few things on my current computer and one of them is going to be a water cooler. It's going into a corsair 750D. I have looked at the cooling section of toms hardware and while looking into the corsair option there is literally 16 different AIO options. I've narrowed it down to 8 by using a double fan on a bigger rad like a 240 or 280 option. But that's still way to many. Going back to the toms hardware sections of the cooling it seems they like the NZXT Kraken X61 as the best but it says this was a 2012 round up. In your best opinion do you think its still the best option? If not what AIO do you recommend and if it is corsair which one of them is the best. Looking into them I don't see much of a difference between the 8 except for maybe a slightly bigger rad.
