Review on Corsair ML120 Pro LED Red Cooling Fan: Premium 120mm Magnetic Levitation for Optimal Cooling - CO-9050042-WW by David Pearson

These fans operate at a very low noise level, but if they are installed in an enclosure to extract air to the outside, you must ensure that the enclosure has minimal obstructions, otherwise they become very noisy even at high speed. low speed! If you want a case fan that is partially enclosed by the case, look for a high static pressure fan like the Phanteks, which is cheaper but much quieter at some speeds when installed to blow air out of the case. .According to the description, this fan should manage the balancing act between high static pressure and powerful airflow, but as an exhaust fan it makes too much noise. On the other hand, the flow direction markings on these fans are tiny. Again, other fans make this much clearer! Overall - disappointed in a Corsair product with high reviews and ratings. I'm hoping to find an alternative use for these two fans.
