I'm trying to get some more mileage from my 2017 build, so i've decided to go watercool and overclock a bit - right now I'm runnig a 7700k at stock + a 1080 with the basic fan cooler. I managed to get thePhoenix Cpu Gpu, a 240 rad and a 140 rad from ekwb for cheapo, and i was thinking about how to maximize efficiency/reduce possible problems: if I put both rad+pump in the same loop, can thy have any problem (I was thinking like CPU > 240 > GPU > 140)? Or should I just have two separate loops, the 240 for the 7700k and the 140 for the 1080?
