Ive got an eheim 1250 and maze 4 gpu + tubing and clips laying about. Im in need of a radiator and rez. I want to buy something which will do both jobs and I considering one of these 2: This could act as a bubble catcher/reservoir with the inlet at the top and outlet at the bottom, and also I can fit a 120mm fan directly on it This will get rid of the bubbles for sure, but will it give enough cooling for a single gpu? Could angle the 120mm at this too and get an 80mm case exhaust on it too. What one looks like the best idea?
