Compatibility and installation

The new Zalman CNPS9900DF is a universal cooler in the full meaning of this word It is compatible with most processors and platforms out there with no exceptions.

Installation process is similar for all platforms and starts by mounting the steel brackets to the base of the cooler:



This photograph shows the retention bracket for the Intel platform. If you intend to install this cooler for AMD platform, you will have to use a different set of straight brackets.

Then, apply a layer of thermal paste on the CPU, install the cooler on it and tighten the Allen screws (with hex-shaped sockets) with the particular L-shaped wrench:

Actually there is a little bit difficult to complete the final step. Firstly, it is challenging to put the screws into the holes of the brackets when tightened. On top of the, the L-wrench inserted into the screw sockets at an angle doesn’t seem to go in, while later you can barely get it out of the socket at all. Nevertheless, 10-15 minutes later the screws are in place and have been perfectly tightened, the cooling device is secure in the motherboard and the processor.

For the cooler compatibility with tall memory module heat-spreaders and other heatsinks around the processor's socket, we can’t state definitively that Zalman CNPS9900DF will not occur any conflict, because its lowest heatsink fins are only 30 mm above the mainboard surface:

However, the lower part of the heatsink is a little tight, which is why it would conflict with memory module featuring a tall heatsink installed near the DIMM slots of the processor.

The manual recommend installing the Zalman CNPS9900DF cooler in the following way:

Install the Zalman CNPS9900DF follow the Manual

In addition, we also tested Zalman CNPS9900DF in an alternative direction, such as turning a 90-degree angle:

Note that we did not record any differences between those installations. And what particular level of efficiency we are talking about? Let's dig a little deeper!

Configuration and testing methodology

We've tested the whole cooling device in a closed system case with the following configurations:

·         Motherboard: Intel Sliler DX79SI (Intel X79 Express, LGA 2011, BIOS 0537)

·         CPU: Intel Core i7-3960X Extreme Edition, 3.3 GHz, 1.2 V, 6x256 KB L2, 15 MB L3 (Sandy Bridge-E, C1, 32 nm)

·         Surface: ARCTIC MX-4

·         Graphic card: AMD Radeon HD 7770 1 GB GDDR5 128 bit, 1,000/4,500 MHz

·         System Memory: DDR3 4x4GB Mushkin Redline (Spec: 2,133 MHz/ 9-11-10-28/ 1.65 V)

·         System hard drive: Crucial m4 256 GB SSD

·         Drive for programs and games: Western Digital VelociRaptor (300GB, SATA-II, 10,000 RPM, 16MB cache, NCQ) inside Scythe Quiet Drive 3.5’’ HDD silencer and cooler

·         Back up drive: Samsung Ecogreen F4 HD204UI ?(SATA-II, 2 TB, 5400 RPM, 32 MB, NCQ)

·         Case: Antec Twelvw Hundred (the front: 3 Noiseblocker NB-Multiframe S-Series MF 12-S2 fans (1020 RPM); the back: 2 Noiseblocker NB-BlackSilent PRO PL-1 fans (1,020 RPM); the top: 200 mm standard fan (400 RPM)

·         Control panel: Zalman ZM-MFC3

·         Power: Seasonic SS-1000XP Active PFC F13 1,000 W (with 120 mm standard fan)

Preparing for the primary test and summary diagram, we've overclocked our 6-core processor with the clock generator frequency set at 125 Mhz, the multiplier at 34x and “Load-Line Calibration” enabled to 4.25 GHz.  The nominal Vcore of the processor is increased to 1.35 V in the mainboard BIOS. The "Turbo Boost" technology was disabled during this testing process, and the Hyper-Threading technology was enabled to increase heat dissipation. The memory voltage was at 1.65 V and its frequency is 2,000 MHz with timing parameters are 9-11-10-28 parameters. All other configurations are available in the mainboard BIOS and related to the overclocking process of the CPU or memory remained unchanged.

All tests were conducted under Windows 7 Ultimate x64 SP1 operating system. We used the following software in the experiment:

The process used during our testing process:

·         Linx AVX Edition version 0.6.4 - to open the processor (memory - 4,500 MB, Problem Size - 24,234, 2 rounds with 11 minutes for each round)

·         Real Temp GT version 3.70 - to control the temperature of the processor

·         Intel Extreme Tuning Utility version - to control and observe the parameters of the system during overclocking section

Thus, a complete picture of the testing process looks like this:

The CPU was loaded with two consecutive LinX AVX test runs with the settings as indicated above. The stabilization period for the CPU temperature between the two test cycles was about 8-10 minutes. We took the highest temperature of the CPU core for the results chart. Moreover, we also offered a table with temperature parameters for all cores including their average values. The ambient temperature was checked next to the system case with an electronic thermometer with 0.1°C precision that allows hourly monitoring of the temperature changes during the past 6 hours. The room temperature during our experiment varied between 24.0 and 24.1°C.

The noise level of the cooling device was measured between 1:00 and 3:00 AM in a big closed room about 20 m2 by using CENTER-321 electronic noise meter. The noise level of each cooler was tested outside the system case when the only noise sources in the lab were the cooler and its fan. The noise meter was mounted on a tripod and 150mm away from the fan impeller. The examined cooling system was placed at the edge of the table on a sheet of polyurethane foam. The lowest noise parameter that our noise meter can read is 29.8 dBA and the subjectively comfortable noise level in these testing conditions was around 36 dBA (do not mix it up with low noise level). The rotational speed of the rotor was adjusted in entire supported range of in-house controller by changing the voltage with 0.5 V increment.

We will compare the cooling efficiency and noise level of the Zalman CNPS9900DF with the Thermalright Spirit 140 with a TY-140 default fan in two operation mode - when running at full speed and at static mode with 800 RPM:

The rotational speed of all fans was controlled by using a special controler similar to which I mentioned above with a ± 10 RPM precision.
