I show You how To Make Huge Profits In A Short Time With Cryptos!

We continue the tests of products from Scythe, after a very good Ashura (test here) I will present the very last of the Ninja series, very simply called the Ninja 4! Was a time very prized by fans of silent PC the first Ninja of the name was a monster for his time and able to cool in passive or with a very light flow of air the most greedy processors, Scythe decides today to try to renew the legend!

Offered at a price of around € 47 including VAT, the Ninja 4 is equipped with a 12 cm Glidestream fan with integrated rheobus and could prove to be an excellent alternative to competing mid-range coolers, if the tests are of course conclusive. see everything up close!

We change completely at Scythe with the Ninja 4, no more question of colors that are obvious! A profile photo of the product as well as the name of the model and the compatibility of the different sockets on the front face, with a drawing of a ninja, it sets the mood! At the back the usual warnings.

On the sides we find on the one hand the technical characteristics (dimensions, weight, fan, etc.) and on the other a listing of the strengths of the “little” Ninja 4. Everything is very sober and the main one is present.

Scythe_Ninja_4_boite5

When you open the box, you can easily recognize the products from Scythe, you come across the small white box containing the bundle.

Scythe_Ninja_4_boite6
Scythe_Ninja_4_boite7

Under the bundle box a piece of cardboard is placed on the radiator, the beast should not be scratched! To the right of the latter, the fan is placed against the cardboard, separated by a layer of foam.

Scythe_Ninja_4_cote1

Here is the beast! 36 aluminum fins with a fairly large spacing favoring cooling with low airflow, which was what it was designed for in the first place. The build quality has gone up a notch here with nickel-plated copper on the calloducts and the base, a little nicer even if very frankly dispensable.

Scythe_Ninja_4_above

The top is shaped like a 4-pointed ninja star, to say the least is that it shines! The calloducts are evenly distributed over the 4 branches, in order to optimize the dissipation surface as much as possible. The beast is really very imposing, the size of a “dual tower” cooler which logically promises excellent performance. It is clear that this changes the tower type coolers that you can see everywhere, and that’s not bad!

Scythe_Ninja_4_below

Scythe has equipped his Ninja 4 with 6 calloducts 6mm thick, all nickel-plated as I said, which gives a high-end side to the thing.

Scythe_Ninja_4_miroir

The base is very well finished without having a 100% mirror finish, we can see the concentric grooves left by the machining. Moreover the base is convex with the top located in its center, that is to say that the maximum pressure will be in the center which is generally where the cores of the processor are located.

Scythe_Ninja_4_ventilateur1
Scythe_Ninja_4_ventilateur2

Scythe supplied with the Ninja 4 a Glidestream 12 cm PWM fan given for 3 different speeds depending on the setting of the integrated rheobus, from 300 RPM for all modes to 800 RPM in “Low”, 1150 RPM in “Medium” and 1500 RPM in ” High ”, enough to satisfy all users, whether those seeking silence or performance. The build quality of the fan is very good, as usual with Scythe.

Scythe_Ninja_4_ventilateur3

The integrated rheobus is in the form of a small 3-notch switch in one of the corners of the fans, “Low”, “Medium” or “High” as you wish!

Scythe_Ninja_4_ventilateur4

The fan cable is of course sheathed, and of very good quality, a little more always nice.

Scythe_Ninja_4_bundle

The bundle is made up of:

  • 1 x Radiateur Scythe Ninja 4
  • 1 x Ventilateur Scythe Glidestream 120 PWM
  • 1 x Intel mounting plate
  • 4 x clips for 12 cm fans
  • 1 x thermal paste tube
  • 1 x Manuel
  • 1 x screwdriver
  • The necessary screws

As you can see the bundle offers everything you need to mount the cooler in good conditions, on the other hand no superfluous here, only what is necessary! The Ashura thermal paste sachet has been changed to a much more practical tube, and Scythe even thought of those who do not have a long screwdriver and provided one, it would be almost like the bundle of a Noctua!

The Scythe Ninja 4 is compatible with all sockets on the market, from the old and obsolete 775 to the very recent 2011-3 at Intel and all AMD sockets, it goes without saying that there will be no compatibility issues if you buy a new PC, at least at the socket level! In terms of weight, the Ninja 4 displays a small 780g without the fan and 900g with it, which in the end is not so excessive when seeing the dimensions of the beast. The radiator itself is 13 cm square, 15.5 cm high, 15.3 cm deep once the fan is installed. The height will allow it to be installed in the vast majority of cases on the market, which is a good thing, in addition to being “thin” enough not to normally interfere with the first PCIe port next to the socket.

There are 36 aluminum fins, which is less important than the other tower type coolers that we have the opportunity to see on the market, but as I said above this will be good in the case of When used with a low air flow, there will not be a great need for pressure to circulate the air between the fins.
The Glidestream 12 cm fan is powered by PWM, 3 speeds are available, 800, 1150 and 1500 RPM for a maximum sound level of 12.5, 23.5 and 29.5 dB respectively, which should logically ensure silent operation of the stupid, to see in the tests!

Available at a price of around 47 € and guaranteed for 2 years the characteristics are rather attractive, it could become an excellent choice for a silent PC, if however it turns out to be efficient in use, this is what we will see !

The assembly is rather simple, just put the back plate like this:

Scythe_Ninja_4_montage1

Then we place the white washers above the 4 holes of the motherboard:

Scythe_Ninja_4_montage2

We then place the screws that will attach the back plate:

Scythe_Ninja_4_montage3

Once the 4 are in place, you have to place the 2 plates that will be used to fix the cooler itself over these same screws, you have to be careful to place the screws in the correct hole (there are 3 locations for 3 sockets different), for socket 1150 1155 1156 it is the middle one:

Scythe_Ninja_4_montage4

We screw the 4 screws to fix the 2 black plates:

Scythe_Ninja_4_montage5

When the 2 plates are placed, you must of course not forget to put a little thermal paste on the processor, and when I say a little it is really a little , as below:

Scythe_Ninja_4_montage6

Now we finally move on to the placement of the cooler on the processor, do not forget to remove the protective film under the cooler, we place the black plate on the base and we put the cooler, which we then screw:

Scythe_Ninja_4_montage7

Be careful, however, it is necessary to proceed alternately and especially not to screw up one screw and then pass on the other, otherwise the temperatures will be completely delusional. Likewise, be careful not to over-tighten otherwise you exert excessive pressure on the processor, unfortunately no stoppers for the screws so do not go like a lumberjack. Thanks to the supplied screwdriver, without which many people would find themselves stuck:

Scythe_Ninja_4_montage8

Then simply put the fan in place using the 2 clips provided, plug it in and you’re done! In the end, the assembly is rather simple, as long as you go slowly and do not over-tighten the screws that hold the cooler to the processor.

Memory / PCIe compatibility

Scythe_Ninja_4_memoire_clearance

You will have to pay attention to the memory chosen, even if the fan can be raised according to the height of the memory.

Scythe_Ninja_4_pcie_clearance

No problem with the PCIe port, the first one next to the socket will be fully usable, a great thing for those who have a motherboard like the one in the test configuration 🙂

The test platform

The Scythe Ninja 4 has been tested on the configuration below:

  • Processor : Intel Core i7 875K @ 3.2 Ghz
  • Motherboard : Asus P7P55D
  • Mémoire: Kingston HyperX 4 x 2 Go 1600Mhz
  • Disque dur: WD Raptor 150 Go
  • Graphics card : Sapphire Toxic 5850
  • Power supply : Seasonic X650

The test protocol

The core i7 875K has been slightly overclocked to 3.2Ghz. The temperatures under load are an average of all the cores for 3 tests of 30 minutes on OCCT, the temperatures at rest were taken after 15mins on the desktop (still an average of the 4 cores).

The cooler has been tested against:

  • be quiet! Pure Rock (tested here)
  • be quiet! Dark Rock 3 (tested here)
  • be quiet! Dark Rock Pro 3 (tested here)
  • Cooler Master Hyper 612S (tested here)
  • Cryorig H5 (tested here)
  • Noctua NH-U12S (tested here)
  • Noctua NH-U14S (tested here)
  • Noctua NH-D15 (tested here)
  • SilentiumPC Fera 2 HE 1224 v2 (tested here)
  • Scythe Ashura (tested here)
  • Scythe Mugen Max (tested here)

The temperatures

Scythe_Ninja_4_results_temperatures

As we can see the Scythe Ninja 4 does not demerit, 61 ° in “Low”, 56 ° in “Medium” and 54 ° in “High” we see very well that the spacing of the fins helps the evacuation of the heat without requiring an enormous air flow since there is only a 7 ° difference between the maximum and the minimum here. It goes without saying that the CPU is clearly not in the red zone and will not overheat with the Ninja 4 installed.

Regarding the ability to cool in passive mode I unfortunately do not have in my possession a processor with a TDP of 65 Watts, so it is impossible to test this mode. In a ventilated case and given the results in “Low” there will certainly not be the slightest problem even if between us and as we will see immediately it will be very difficult to hear it with the fan at minimum, you might as well keep it.

Noise pollution

Warning: Part to be taken with a grain of salt, unfortunately not having access to the appropriate equipment and using an android application to take the readings The measurements below are only indicative! The readings were taken 15cm from the cooler.

Scythe_Ninja_4_results_sound_ nuances

There again it is really very good for the Scythe Ninja 4, particularly in “Low” and in “Medium” the sound level reaches respectively 32 dB and 35dB, as much to say that at this level and once in a closed box you won’t hear it! Once the fan is set to “High” on the other hand, the beast becomes audible, even if this remains very tolerable. The fan itself does not really suffer from any defect, no noise coming from the engine, turbulence, friction, only the noise of the air flow, it is really very pleasant for our little ears!

Scythe_Ninja_4_random

Here we are at the end of this test, what to say about this Scythe Ninja 4?
Taking over from the excellent Ninja series at Scythe version 4 is clearly not a disappointment, on the contrary! The build quality is simply excellent, the callpipes and the base are nickel plated for your viewing pleasure and the beast is very big while sparing the first PCIe port, which could be a real relief for people with a motherboard. with a 16x PCIe slot glued to the processor socket.

The performances are really very good, particularly when the air flow is weak (in “Low” or “Medium”), it will be able to cool a processor without the slightest problem. The noise pollution is also excellent, thanks to the rheobus integrated on the fan which allows to adjust among 3 speeds, 800, 1150 or 1500 RPM maxmimum. In addition to being silent, no parasitic noises or friction to be deplored on the Glidestream 120 PWM, what are the people asking for?
The only small downside of the Ninja 4 is that you have to pay attention to the height of the memory modules, which is not really new and is the case for many coolers, “Low profile” will be a must.
Offered at a price of around € 47 including VAT and guaranteed for 2 years, the Scythe Ninja 4 is really an excellent candidate for a Quiet PC and therefore having a limited air flow.

Advantages

  • Performances
  • Noise
  • Does not block the first PCIe port
  • Build quality
  • Price

A big thank you to Scythe who allowed me to do this test.
