Do the job
LDLC perfect. Packaging and delivery time = RAS. Bought to replace a Corsair Carbide 500 R case Ar fan => Verdict = This "magnetically levitated" fan makes more noise than its predecessor after 10 years of service. It seems that only the rolling noise was of concern to the designers. The fan is correct but does not go unnoticed above 1,200 to 1,400 RPM. Most of the noise is aerodynamic. Recommended for those who have a Rheobus or a software like FanXpert to find a good compromise between speed/noise/efficiency. I still note the lack of acoustic progress in 10 years.
