Arctic P12 Max vs Lian Li UNI FAN SL140: Comparison
What is the difference between Arctic P12 Max and Lian Li UNI FAN SL140?
The gap that matters here is static pressure: Arctic P12 Max 4.35 mmH2O against Lian Li UNI FAN SL140 1.67 mmH2O, which puts Arctic P12 Max 62% ahead. Add airflow to that, 81.04 CFM on the Arctic P12 Max versus 70.5 CFM on the Lian Li UNI FAN SL140, and the pattern holds. Add warranty to that, 6 years on the Arctic P12 Max versus 2 years on the Lian Li UNI FAN SL140, and the pattern holds.

Who each one is for
Take the Arctic P12 Max for radiator and dense heatsink applications needing high static pressure at a budget price. Avoid it for silent-first builds that never need the fan's higher speed range, a quieter-tuned fan may suit better at low RPM. Buy the Lian Li UNI FAN SL140 for mixed 120/140mm UNI FAN SL builds and quiet open-air intake and exhaust, though it is the wrong buy for radiator duty needing higher static pressure and builds without a case window. Our rating of the Arctic P12 Max (8/10): the highest static pressure in our case fan lineup at a budget price, ideal for radiators and dense heatsinks. Our rating of the Lian Li UNI FAN SL140 (8/10): A quiet, good-looking 140mm ARGB fan that pairs cleanly with the rest of the UNI FAN SL lineup.
