The CNPS11X Performa is another member of the CNPS11X family, like the CNPS11X Extreme that we already tested. Similar to its brother, it has a V-shaped heatsink and a 120 mm fan, but it has only four heatpipes. Let’s test it and discover which one performs better.
Comparing the CNPS11X Extreme and the CNPS11X Performa, they look pretty much alike at first sight. The only features they actually share are the shape of the heatsink and the size of the fan; while the Extreme has five heatpipes, the Performa has only four. The base is also different, as the Extreme has a nickel-plated base, and the Performa has direct-touch heatpipes. The fan is dissimilar, too.
The box of the CNPS11X Performa is presented in Figure 1.
Figure 2 shows the contents of the box: the cooler itself, a small bag of thermal compound, a manual, and installation hardware.
Figure 3 displays the Zalman CNPS11X Performa.
This cooler is discussed in detail in the following pages.

Figure 4 illustrates the front of the heatsink, where you can see the black, simple 120 mm fan.
Figure 5 reveals the side of the cooler, where the four heatpipes are exposed.
The rear of the heatsink is shown in Figure 6.
In Figure 7, you can see the top of the heatsink, which is closed by a larger fin. Here is also a clear view of the position of the wire fan holders.

The base of the cooler is seen in Figure 8. The heatpipes keep direct contact to the processor.
In Figure 9, you can see the CNPS11X Performa without the fan. Notice that the bottom of the heatsink is closed with a larger fin, but it has folds that direct part of the airflow to the voltage regulator of the motherboard.
Figure 10 shows the PWM fan that comes with the CNPS11X Performa.
The first step in the installation process of the CNPS11X Performa is to screw two metal clips to the base of the cooler. Figure 11 shows the clips to be used with Intel CPUs in place.
Figure 12 reveals the backplate used to install the cooler. You must install the nuts at the backplate in the holes matching the socket used by your CPU.
Locate the backplate at the solder side of the motherboard, put the cooler over the CPU, and hold it in place using four screws, as shown in Figure 13.
The last step is to install the fan, as you can see in Figure 14.
[nextpage title=”How We Tested”]
We tested the cooler with a Core i7-860 CPU (quad-core, 2.8 GHz), which is a socket LGA1156 processor with a 95 W TDP (Thermal Design Power). In order to get higher thermal dissipation, we overclocked it to 3.3 GHz (150 MHz base clock and 22x multiplier), keeping the standard core voltage (Vcore), which was the maximum stable overclock we could make with the stock cooler. Keep in mind that we could have raised the CPU clock more, but to include the stock cooler in our comparison, we needed to use this moderate overclock.
We measured noise and temperature with the CPU idle and under full load. In order to get 100% CPU usage in all threads, we ran Prime 95 25.11 with the “In-place Large FFTs” option. (In this version, the software uses all available threads.)
We compared the tested cooler to the Intel stock cooler with a copper base (includ
ed with the CPU), as well as with other coolers. Note that in the past, we tested coolers with a socket LGA775 CPU, and we retested some “old” coolers with this new methodology. This means you can find different values in older reviews than the values you will read in the next page. Every cooler was tested with the thermal compound that accompanies it.
Room temperature measurements were taken with a digital thermometer. The core temperature was read with the SpeedFan program (available from the CPU thermal sensors), using an arithmetic average of the core temperature readings. During the tests, the left panel of the case was open.
The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed 4″ (10 cm) from the fan. We turned off the case and video board cooler fans so they wouldn’t interfere with the results. This measurement is only for comparison purposes, because a precise SPL measurement needs to be made inside an acoustically insulated room with no other noise sources, which isn’t the case here.

The table below presents the results of our measurements. We repeated the same test on all coolers listed below. Each measurement was taken with the CPU at idle and at full load. In the models with a fan supporting PWM, the motherboard controlled the fan speed according to core load and temperature. On coolers with an integrated fan controller, the fan was set at the minimum speed on the idle test and at full speed on the full load test.

In the graph below, at full load you can see how many degrees Celsius hotter the CPU core is than the air outside the case. The lower this difference, the better is the performance of the cooler.

The performance of the Zalman CNPS11X Performa is excellent for a cooler of this weight and size; it is also quiet and beautiful.
In our system, it performed better than the CNPS11X Extreme, which may sound a little strange because the Extreme is probably priced higher, but perhaps the direct touch heatpipes improved the whole design, even with one fewer heatpipe. This may also be the case because the Performa doesn’t have the installation issues that we found with the Extreme.
Because of the cooling performance with good noise level, nice look and low weight, the Zalman CNPS11X Performa receives our Silver Award.
