Given the surface area being equal, I assume performance will be similar. It seems two radiators will be slightly more restrictive, but likely not enough to cause major performance decreases. Does this just come down to mounting options etc.? I was thinking about doing 2x240 Monstas in my Enthoo Primo case (one in the front, one in the bottom) instead of one Monsta 480 in the bottom. It is a bit easier in this configuration for a drain port and tubing. Is this better or worse? Will airflow from the front be changed dramatically and thus cause any issue? What should I be concerned with or am I not addressing?
