The TRUE Spirit was very proficient at cooling our Core i7-965 processor. Using the stock fan at 12V the thermal rise was only 38°C and this increased gradually to 46°C at 5V, an 8°C spread. Our reference Nexus fan performed with better efficiency, posting better temperatures at equivalent noise levels, but the overall difference was small.

The CNPS10X Quiet using the stock fan performed just as well as the TRUE Spirit at similar noise levels. The Quiet seemed to get a bigger boost from our reference fan though, as the stock fan at 9V measuring 19~20 dBA got the same result as the Nexus fan at 12V measuring only 16 dBA. At lower fan speeds and noise levels, the difference between the two fans was minute.

The TRUE Spirit and CNPS10X Quiet placed very well on our performance chart, beating previous champions including the Ultra-120 and Ultra-120 eXtreme. This is surprising for the TRUE Spirit, as it is a smaller version of the aforementioned heatsinks. We surmise that the wider fin spacing and slimmer profile allows more efficient cooling airflow. However, if the processor clock speed and/or voltage were cranked up, the lack of surface area would likely be to detrimental, and larger coolers like its bigger brothers would win out.

The CNPS10X line failed to impress us until we tested this Quiet version. The CNPS10X Quiet easily outpaced both the Flex and Extreme, especially with our reference fan at 7V. The wider fin spacing obviously gives it a big edge when paired with a low speed fan as that is the Quiet's most notable difference compared to the other members of the CNPS10X family.
