if you think about it
GPU's produce quite a bit of heat. most of them crunch as much power if not more than regular processors and their thermal dissipation is very similar. Adding another waterblock with a high end graphic processor on the other end definitely could increase your temps...but I always test one mod at a time unless I am dead sure. If you apply a ton of changes to your rig and then encounter something confusing there's almost no way to find out other than through the process of elimination. Good to hear that a couple of higher CFM fans can make that much of a difference though..hope they're worth the added noise
