This fan does an excellent job in cooling down our industrial machines. The black color fits well with the overall look of our equipment. The only downside is that it is a bit noisy but it is a minor issue. As an Industrial and Scientific company, we highly recommend this product for those who are looking for efficient thermal management products..
Pros
Quiet operation with a maximum noise level of 22.8 dB(A)
Cons
May produce insufficient airflow for larger PC builds
Bought elsewhere but thought a review might be useful anyway. Not bad at all for air cooling. Pretty quiet and can blow air through the hard drive like no other. Heat sinks, on the other hand, hit so hard that even the PWM series can't push through enough air. These are airflow fans, so they don't work well when you need to force your hair through wheel or tightly mounted discs.
