Test result:

The coolers from Zalman will be tested against the recently reviewed Noctua NH-U9 coupled with a YS-Tech 50CFM 92mm fan, and the very strong stock cooler for the X2 4400+ with four heat pipes.

The temps were measured using the latest version of ITE Smart Guardian. Idle temps were obtained upon reboot and after been idle for 15 minutes. Load temps after 30 minutes of running dual instances of “toast” on high priority.

The ambient room temp was kept between 23-25°C during the period of testing. Arctic Silver 5 was used with all the coolers and applied accordingly to Arctic Silvers recommendations.

As you can see in the above chart the CNPS8000 is performing quite well. It is able to beat the very capable AMD stock heatsink with the fans on full by a couple degrees all the time. It only loses by one degree when the fans are spinning on the low setting; this is very nice especially since the CNPS8000 mainly is made with SFF systems in mind. And I also have to mention that on the low speed setting the 8000 HSF is as close to silent as a spinning fan can be which is extremely impressive. The CNPS9500 AM2 is able to beat the stock cooler with several degrees at all time, it also is very even to the excellent performing Noctua NH-U9, and it only loses out to it in the over clocked environment by 1 degree Celsius. This can however depend on many factors like ambient fluctuation etc, so I call it a draw between them.
