Dual rad custom loop fully using EK's Fluid Gaming watercooling parts that are, as titled, Aluminium based. Main reason for going Aluminium not Copper is the price which at the time of building was the main factor and I desperately wanted a custom loop.

I have a 360 up top which originally interfered with the rear exhaust fan when I had my 240 at the front, so I had to drill extra mounting holes at the front to lower the front rad, slide the top along and then could fit the rear exhaust fan. Also had to drill a hole for the reservoir clamp so it would be centred with the beauty panels.

System is incredibly quiet under full load which was another focus, and I have quite conservative overclocks for that reason.
GPU has +100 on the core and +600 on the memory, while gaming is between 50 and 60c.
CPU OC is controlled by ASUS AI and while gaming generally is 4.7ghz and around 70c.
