Hello, since I'll be putting two new hard drives into my PC for a raid 1 set up, pushing the total drives I have in the cages to 4 (SSD, and 3 HDD. Can't put SSD behind motherboard due to PSU right angle connectors), I'm going to need higher static pressure fans than the GP 140s that come with the case. (Case: Define R5, with an insanely long PSU preventing a side by side HDD cage set up). Which affordable fans would you suggest with enough SP for this extremely tight situation(Door of case on one side, HDD cage on the other). Which SP would you think is minimum for this situation? I'm thinking ~1.8mmH2O would be about the minimum
