Also, many fans designed for computer use are supplied with dampers or shock mounts. Two that I particularly like because they are high quality and very quiet are Cougar and Noctua. The latter is about twice the cost of the former, both are excellent, the Noctua lasts longer.
Fan noise is often of much greater concern to computer users than to radio users (yes, yes, we are both) because a high-performance PC can have as many as 10 fans on board. Thus, computer fans usually come with detailed noise specs as well as the above-mentioned damper mounts. Fan speeds are often variable, as well, either by controlling voltage or PWM.
