Zalman CNPS10X Quiet CPU Cooler Review
 

The Zalman CNPS10X Quiet cpu cooler can be summed up to be a quiet winner. Although the installation was a little daunting, the performance after the fact made this cooler worth the effort and frustration. It beat everything with ease and could even be used for mild overclocking if temperatures are monitored and the speeds adjusted for the fan's capacity.
