Final Thoughts and Conclusion

Although the Zalman CNPS9900 LED looks great and has the pedigree of a champion, I wasn’t too thrilled about its performance results during our idle and load testing. While the Vigor Monsoon III LT is no slouch when it comes to CPU cooling, we’ve come to expect more from Zalman over the years.

The standard Zalman heatsinks are held to might be a bit unfair, but their history certainly makes them a target for any vendor who wants to knock them off the top spot in the air-cooled heatsink industry. While the dual-heatsink design is sound on paper, I don’t think it worked when it was executed. I might be making something out of nothing because the results were very close to the Monsoon III LT, but it just seems that their heatsinks should stand out from the pack and not just stay even with them. Overall, it did function as advertised and provided more than adequate cooling for our i7-920. So, in those respects, we should give kudos to Zalman for a job well done.
