Can there really be that much difference?
Corsair master Fan 120mm and 140mm.
From my Amazon Review:
These fans are made of really high quality, dense plastics, that feel and sound dense, not tinny when you tap them. However, after actually looking at the specs, something I always do but this time I failed to do before buying these fans (their Cooler Master, right?), these fans are pure garbage.
Additionally, after using them for a short while, they developed a vibration in 140mm motor bearings and a howling acoustic noise in the 120mm.
EVIDENCE
Here is how the CM MMF120 fans compare to Enermax and Noctua:
CoolerMaster MF120
650 - 1800 RPM
47 CFM (no minimum rating)
1.6 mm-H2O
30 dBA
MTTF: 160,000
Enermax Squ120 Specs:
300-1500 RPM
68 CFM (44% higher than CM MF120)
1.9 mm-H2O (18% higher than Cm MF120)
23 dBA (23% less dBA)
MTTF: 100, 000
Noctua Redux 120
450-1700 RPM
70 CFM (49% higher than CM MF120)
25 dBA (17% lower than CM MF120)
2.83 mm H₂O (75% higher than CM MF120)
MTTF: 150, 000
CONCLUSION
Bad acoustics and internal quality. Garbage. DO NOT WASTE YOUR MONEY!
I swear if Noctua ever comes out with a good looking RGB fan, and I need RGB, I'll never look back. But, since this new build is my last RGB/Display build, I'll probably always go Noctua from here out.
My first ever RGB / Display build, and 2nd to last: https://forums.anandtech.com/threads/anandtech-member-case-gallery.159088/post-40867566
