Question about Arctic P12 Value Pack

there must be a reason why noise is indicated in dba...

yes, they are really 'louder'(funny word) than others that were given in this range... don't think that a human being verifies all the data for every device, it's not a crime to give something a little wrongly by mistake and in the end it's much cheaper.

The fans are quiet and very efficient, fans are adjustable, low rotation means quiet (inaudible) full rotation (perceptible from the housing) ps.everyone perceives noise differently. also depending on ambient noise
