Regarding the furyx and the use of an AIO as a cooling solution. It would be interesting to see how one would run on a standard cooler. AIO coolers are very popular now for gpu's, either factory solutions or aftermarket such as the corsair bracket solutions. I currently own an msi gaming edition 980ti, a very quiet card that has actuallky been shown in some reviews to run quieter than a furyx. But, it does run hot on the stock fan setting, (75c) I prefer to use a custom 1-1 fan profie which keeps it sub 65c when gaming but still quiet.
Also, i suppose on the furyx rad you can swap out the stock fan/s for something of your own. And for anyone who has done so, i wouldnt mind hearing which fan/s you have opted for.
