I bought the a240g kit as my first dabbling w/ watercooling. The 240mm rad is not enough to cool my 1080ti/7600k suitably with CPU temps in the mid 70s with a fan curve that I find optimal (1200rpm under load). As such I'm looking at getting an additional rad. They sell 120mm/240mm aluminum rads on the EK site. However, a local store has the 120mm rad for a pretty good price- but I'm not sure that getting the 120mm would suffice in dropping temps? Would you advise that I get the 120mm or fork out a bit more cash and then get the 240mm? I assume by adding another 240 rad I could probably even run the fans a bit lower due to the added SA for heat dissipation?
