I replaced one of my RS240s with a Black Ice Stealth 360 GT and while back and saw an epic drop in GPU temps. That got me thinking, why not combine both of my loops, as the net effect on both GPUs and CPU should be better than two singles, each with 240 rad. So, I did. Pic of the back of my Dual DDC Res. The GPUs still run 10 degrees lower (at load) than it did with their own 240 rad and now the CPU temps have also dropped a further 5 degrees at load. The benefits (as I see them): Improved flow rate from the DDCs in series. CPU & GPUs sharing both rads. Pump redundancy - should still run if one pump craps out. Single drain point for the whole system. Disadvantages: increased restriction and ??? Anyone got any downsides I should be aware of? Cheers Spreadie
Cost and power usage mainly, but seeing as you have them that's not an issue. As far as I'm aware you shouldn't have any other issues And this is why we always say to use just one loop
