Hardware Canucks posted a review of the Gelid Silent Spirit CPU Cooler

As for the Silent Spirit cooler itself, this is an ultra quiet, hybrid downdraft cooler which is designed as a low noise solution. It is slowly becoming available at retailer and e-tailers throughout the country and should go for about $35. The Silent Spirit is not designed nor intended for monster overclocking, nor is it designed for passive cooling. What this cooler has been designed to do is provide adequate cooling and do it with as little noise as possible.
