Zalman CNPS6000-Cu Heat Sink Review - Conclusion page 2
(Page 2 of 2 )
TESTING:
As always, I test my heatsinks with no case fans to aid in cooling. A temperature probe was used and was placed close enough to touch the CPU core and not cause any interference between the heatsink and the core. A fresh layer of Arctic Silver II was applied. For comparison, I used a Sunon 80mm fan. The room temperature is kept consistent at 73F with air conditioning on throughout the entire testing procedures.

Results
Concerns:
There was not much problems in installation. Everything was smooth and easy. It was not big enough to get in the way of any of my parts.
Conclusion:
The CNPS6000-Cu is not a bad heatsink at all. Using this heatsink to run stock speeds on your cpu is satisfactory and will even be very pleasant since it'll be very quiet--silent actually. Although AMD says that their processors can reach temperatures of 90c and above, I would never let my cpu get that high. I'll get a heart attack when that happens. Anyway, back to my point. The CNPS6000-Cu is only suited for running your processor at stock speeds, not overclocked. Unfortunately for the price of this heatsink, I wouldn't really suggest anyone to get it. There are other alternatives for getting a large heatsink with a quiet fan and still be able to keep temperatures down while running an overclocked cpu. If you insist, this heatsink will actually attract some attention in a case with a modded window.
Pros/Cons
Pros:
* Good looks
* Easy installation
* VERY quiet
* Great for case modders with windows
Cons:
* Exceeds weight limit
* Uses old tradition clip
* Pricey
* Poor performance
Final Rating: 5/10
