Would you rather I whisper in your ear against your will or scream in your ear against your will?
Lower noise is considered better.
But what if your whisper is so quiet it cant be heard????
Analogy aside, why would you want to hear the fan?
You wouldnt. Was a joke :D
Well theres a few factors at play.
Fans with high RPM tends to move a lot of air and generate more noise.
This is usually alleviated by your case with sound dampening materials and a better fan curve.
People normally want less noise but in a good case and if the PC isn't next to you (under your desk/enclosed) this sometimes doesn't really matter.
But generally, the lower the noise, the better.
a lower noise level means it's quieter. Usually louder coolers cool better than the other coolers in the price bracket but, of course, at the cost of greater noise.
Not usually but this would depend on you.
Generally, you want low noise and high CFM... Though there is a correlation between these elements. Better fans can keep the noise down, however and the CFM up.
What is CFM?
Cubic feet per minute; the amount of air displaced by the fan. The higher the number, the more air is moved. 70 CFM seems to be the average while I've seen them as low as 27.
If you're talking about decibels (dB), lower is quieter.
As for whether louder = better cooling, it depends. A fan running at a higher rpm will be louder and facilitate cooling better than the same fan running at a lower rpm. But a cooler with a larger heat sink and fans running at a low rpm will perform as well as or better than one with a smaller heat sink and fans running at a higher rpm.
