The recording begins with a six second stretch of the ambient noise of the test room. This is followed by 10 seconds at each voltage level. Please set your playback volume so that the ambient noise is almost inaudible, then don't adjust the volume control again. For best results, save the sound file to your own PC, then listen.

The Zerotherm Zen FZ120 is a formidable CPU cooler. Not only does it perform well, its mounting system is secure, and the installation procedure is straightforward. There is no need to fiddle around with various sets of screws, wings, nuts, washers or other doo-dads — manual dexterity is taken out of the equation. It's also an all-in-one solution, as a fan with PWM functionality is included.

The fan is a weak point. It is a fairly typical stock fan — loud at full speed, with mediocre acoustic quality. Fortunately, lowering the fan speed should be easy since almost all current motherboards sport PWM fan speed control. When slowed to 700 RPM or lower, it is quiet enough for most users. While it doesn't perform as well as our reference Nexus fan, that is not unusual. Fan selection is usually an afterthought for most manufacturers, and they tend to choose high airflow capability over best acoustics.

Overall, the Zen is an excellent heatsink with few surprises. Its US$50 price tag is pretty good unless you're not satisfied with the stock fan. But at least one of SPCR's affiliate online stores is selling it for as low as $40, which is an excellent deal.
