Hi All. Thanks in advance for your input. I consider myself to still be somewhat of a n00b. I have rebuilt my loop 4/5 times as I've upgraded PC parts and cooling parts. Most recently I've upgraded from a 240 & 360 rads to 2 420 rads. I am currently running a single loop with said 2 420 rads. Res/Pump -> Hardware Labs Black Ice SR2 420 MP -> CPU -> Chipset -> GTX 1080 -> GTX 1080 -> Hardware Labs Black Ice SR2 420 MP -> back to the Res/Pump For the most part I am happy with my overclock & temps...but like every Overclocker out there I want every drop of extra (everything) that I can get. My proposed new Y-Split loop would go: Res/Pump -> Y-Splitter -< -CPU -> Chipset -> Hardware Labs Black Ice SR2 420 MP - back to Res/Pump GTX 1080 -> GTX 1080 -> Hardware Labs Black Ice SR2 420 MP - back to Res/Pump Basically 2 loops after the Y-Split, then heading back to the same Res/Pump. There is no Y-Split back to the Res/Pump. My Res/Pump has 1 Out ports, and 2 In ports. I'm curious to know your thoughts, and/or results if anyone has tried this before.
