So let's wrap it up. We have a heatsink that advertises itself to be quiet as a mouse; and it accomplishes this task without doubt. We have a heatsink that has a very unique design, and will look pretty awesome sitting inside a case with a huge window bored through the side. And we have a cooler that has a retention system that isn't revolutionary, but is considerably better than a vast majority of the competition. Oh...did I mention that it is really quiet?
The addition of the Rheo-bus is also a very nice touch. Sure, it's a small one, but it does it's assigned task easily and still gives enough play room to be able to accept a larger fan without burning out on you.
But the fan included won't really be enough for the truly high-end PC Enthusiast. It is effective, and doesn't raise the temperatures of the test system to that dreaded 50C mark, but it does come a little close. It was nice to know, however, that it could be changed out very easily without having to remove the heatsink from the processor.
Finally, there is the price. While it isn't the most expensive cooler on the market, it ranks rather high at a retail price of US$45. Of course, if you really want a quiet system, then the cost is worth it. (Did I mention that it is really quiet?)
Bottom line...If you're one of those people who are just sick and tired of the constant throbbing eardrums that are the result of loud fans, then do yourself a favor and get a Zalman HSF. While a little pricey, it lives up to its reputation of being a quiet cooling solution.
