What is considered quiet for a case fan?
Generally speaking, 140 mm fans will be a little quieter than 120 mm ones. They are capable of generating higher airflow and not having to reach super high fan speeds. That is why if a computer can take a 140 mm fan, it usually is the recommended way to go.
What dB is a quiet PC fan?
Noise Levels On average you can expect the quietest fans to make 10 – 35 dB of noise.
What is a 92 mm fan?
92mm fans are most often used as case fans to provide extra airflow through the computer case. To convert airflow in cubic feet per minute (CFM) to cubic metres per hour (m³/h), multiply the CFM figure by 1.7.
Are large fans quieter?
Remember: bigger fans push more air through the hole, but they often spin slower, which results in the same end-result of air displacement but at a much quieter, often life-extending rate (faster fans have a tendency to heat up sleeve bearings rapidly, resulting in early death of the fans).
Are thicker fans quieter?
The thicker fans also generate more noise as they encounter airflow resistance, due to the fact that the fan blades are cavitating more. In contrast, the thicker fans are capable of higher CFM ratings (in free-air testing), due to the fact that the larger fan blades can “shovel” more air through the fan casing.
Is 65 dB loud for a fan?
Sound-power level LWA in dBA i frequency bands to inlet, outlet and environment of the fan….Noise characteristics of the equipment are shown in the tables indicating:

| 60 | noisy | office standard |
| 65 | loud conversation (1 m) | |
| 70 | several loud conversations (1 m) | |
| 75 | shout, laughter |
Are bigger fan blades quieter?
