The slowly spinning fan on the Igloo 2310 keeps it soothingly quiet (41dB(A)). The workmanship that went into the aluminum heatsink is also beyond reproach.
The installation would be less of a hassle if the clip were more tractable.
This cooler is powerful enough to chill a 1400 Athlon or an XP 2000+. It is neither suitable for nor designed to be used on an overclocked CPU.
