Here comes the test of last ventirad Zalman CPU from the CNPS9900 LED, which gives birth to a new structure of production.


Presentation, bundle
  • The new solution comes in Zalman great resealable cardboard box with a blue design.
  • A window reveals parts of ventilator.
  • All features are displayed on the back of the packaging.
  • The ventirad is contained and protected in a plastic shell.



  • While the bundle is placed under the ventirad.
  • It consists of a plastic backplate sockets 775, hardware for sockets 775, a retention clip and screws for attaching 939/M2 sockets (+), those for the 1366 platform installation guide in several languages, a jar of thermal paste Zalman ZM-STG1 Zalman and a sticker.
  • In other words, the bundle is very well supplied and rich.
  • We note the absence of a knob to control ventilation. But this is (the reason is described below).
  • The Zalman CNPS9900 is impressive. Its solid copper look impressive.
  • Its shape is round. Copper fins form two parallel disks hollow in the middle which is a propeller.
  • The fins are maintained by copper heatpipes bent into a circle.
  • The size of ventilator is quite impressive with dimensions of 94 x 140 x 158.5 mm.



  • The heatpipes are three and a diameter of 6 mm.
  • They start from a basic copper very well polished.
  • The structure of the database is a classic: a lower copper which is filed on the heatpipes covered with another party this time in aluminum.
  • As always, quality ventilator manufacturing is exemplary. Finishes are impeccable.
  • We also note the presence of a plastic shell between the two copper disks.
  • The translucent shell is rather off-putting to the eye and one wonders at first sight of its role as the flow of air should be confined with that performance and then reduced.
  • Fortunately, you can remove the shell by unscrewing two screws at the bottom.
  • It is to solidify this all while maintaining a solid structure between the two copper disks.



  • Once the hull removed, it is better inside and organization ventirad.
  • The fan base is anchored on a copper disk in which spend two heatpipes. The other radiator does for its one heatpipe through the entire circumference of the radiator.
  • The heatpipes start from the basis in different directions.
  • The heatpipes go all in one direction to form circles.
  • Forging quality is excellent.



  • The base is classic. It is a copper plate on which are deposited heatpipes. No DTH technology here.
  • The surface of the base is a perfect mirror. This does not necessarily guarantee better performance but it is excellent work.
  • The fan who is not part (single helix) measuring 110 mm in diameter and is bright blue.
  • Speed is controlled by the 4th pin power cable that is not heathed.
  • This cable PWM explains the lack of speed controller in the bundle.
  • The fan runs from 1000 to 2000 RPM for a noise of 19.5 to 38 dB.


Finish with the overall characteristics ventilator. Note the compatibility with the new Intel socket 1366.

  • Dimensions: 94 x 148 mm x 158.5
  • Weight: 782 g
  • Material: Copper
  • Rotation speed breakdown: 1000 to 2000 RPM
  • Noise: 19.5 to 38 dB
  • Bearings: Ball
  • Compatibility: LGA775, Socket 754/939/940, Socket AM2 (+), LGA 1366
  • Note the compatibility pleased with the Core i7.
  • With 2205 cm ^ 3, the Zalman is impressive in size but not the most massive. Especially his height that could pose problems in some cases. For the rest, it fits easily into the boxes tus medium and large tower.
  • For fixing, you should use a backplate or a detention after the socket. In all cases, we must remove the motherboard to fix them back.
  • Then comes the placement of ventirad on the CPU and the setting is by screws. It will be maintained in the ventilator for screwing up. It is more difficult than fixing Pushpins and it poses no real problems.
  • The very basic compact ventirad allows mounting on almost all motherboards.
  • The ventilator is well maintained with the system used.


Test Results
  • We measured temperatures with and without the plastic cover to find the results in temperature 12V to 50% and 100% CPU. We found what we expected: the lack of supply of plastic cache advantage of ventilation and gives better performance. Without the cache, it needs to be handled with care for the ventirad not bend radiators and not getting caught fingers in the fan running.
  • For performance with the cache, they are good but a bit disappointing. There are, for example 2 to 3 ° C less than a CNPS9700. In the end, the Zalman CNPS9900 sided good Black Samurai stroke. This is not the best CPU ventilator but a good one. This is already not bad.
  • Without the cache, temperatures drop! It was 3 to 5 ° C in less!
  • The ventirad rose as among the best ventilator this time, just behind the Cooler Master V8 and finally better than the CNPS9700 (2 ° C). It is a little better than 1 to 2 ° C a Noctua NH-U12.
  • Plastic hull is this if you want to express all the capabilities of ventilator!.
  • For testing sound, as we usually put a meter to 3 cm from the ventilator on the opposite side to the flow of outgoing air. The sound of the laboratory is 30.4 dB.
  • At low speed (5V), the 1000 RPM fan give a very low noise and almost inaudible. It is very appreciable.
  • As against, 12V, where the speed of light is doubled, it's a little gate, since over 50 dB to 55.3 dB. What makes the ventilator for the coup ventilator audible.
  • It will instead set the ventirad on average speed with a knob if you want to be quiet on noise.
  • Remember that the ventilator without potentiometer comes as regulated by 4 pins (PWM).
  • In general, the Zalman CNPS9900 is rather silent as it offered a good position in the ranking in average noise.


Conclusion
  • Zalman continues its momentum by offering a ventilator extreme quality copper dressed.
  • The performances are well go with a very good thermal paste delivered and studied design.
  • Regrettably noise just a little push at full speed and usefulness of the plastic shell if it is security...Without this hull, the performance is much better.
