Overall, I wasn't too happy with the performance of the Zalman CNPS5500 heatsink/fan unit. It was outperformed by the stock Intel unit at idle temperatures, and only managed to move a few degrees ahead of it under full load. That said, installation was very simple and the "Fan Mate 1" gadget is a nice addition for those of you that need complete silence while working at your PC.
The Zalman CNPS5500-Cu has a RRP (Recommended Retail Price) of AU$99, which is definitely far from cheap. Considering the fact that the CNPS5500 barely differs from the stock Intel unit in both performance and noise output, I find it very hard to recommend this product. The bottom line is, the performance of the Zalman CNPS5500-Cu does not justify the AU$99 price tag, and if you already own a stock Intel heatsink/fan unit (should have come with your processor), I recommend that you keep it and save the money.
