Hi all !

It has been some time since I had a product from Scythe on hand, the most recent being the excellent Kaze Master Flat II rheobus (test here), today I am going to present one of their coolers. I named the Ashura! This cooler is not a newcomer but still deserves to take a look, indeed the products from the Japanese manufacturer have always had an excellent quality / performance / price ratio and the Ashura should logically stay in this trend. Tower format, 14cm fan as well as 6 calloducts are part of the game, all of which can be found at a price of around 39 € which places the beast at the entry of the mid-range, an excellent alternative? This is what we will see!


As usual at Scythe the box is very busy and colorful, Japanese style! Various information is available on the front panel, multi-core compatibility (happy again !!), asymmetrical design, GlideStream 140 PWM fan, versatile as well as a new fixing system and some logos of press awards. At the back we find the various warnings and this in 3 different languages ​​(Japanese, English and even French!).


On the sides we find the well loaded Japanese tab, compatibility of different sockets, technical data etc.


When opening we fall on a small foam plate protecting the contents of the box.


Inside the box everything is well packed, a compartment for the fan, a compartment for the cooler and the box containing the bundle, only 2 foam plates on the sides serve as padding, a pity not to have put a little more padding especially below because the cooler itself rests on the cardboard.


In the box we find the cooler, the fan and a box containing the bundle.


Here is the beast! As you can see the design is rather classic. An aluminum base crossed by 6 copper calloducts (not anodized) as well as 50 aluminum fins plus 1 thicker and black above. The build quality is good, combining a good finish but ignoring the superfluous such as the anodizing of the calloducts.


In profile we find a rather thin cooler with an asymmetric base which can therefore be moved away from the memory modules in order to ensure maximum compatibility. Notches are hollowed out to secure the attachment of one or two fans.


Scythe decided to go a bit extravagant here with a black aluminum plate above proudly displaying the brand’s logo, sober but effective!


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.

The Glidestream 140 PWM delivered with the Scythe Ashura, it rotates at a maximum speed of 1300 RPM, the mounting holes are the same as a 12 cm fan as is done more and more for this type of fan. The blades are thin and seem long due to the smaller than average motor. At the back there is a sticker on which is written the model as well as the maximum consumption of 4.44 Watts (0.37A on 12V).


The fan cable is braided and of very good quality, a little extra for those who would be disturbed by a cable of all colors 😉


The bundle is made up of:

  • 1 x Radiateur Scythe Ashura
  • 1 x Ventilateur Scythe Glidestream 140 PWM
  • 1 x Intel mounting plate
  • 1 x kit de fixation AMD
  • 4 x brackets for 12 cm fans (or 14 cm fitted with 12 cm brackets)
  • 1 x sachet of thermal paste
  • 1 x Manuel
  • 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! A tube of thermal paste could still have been more practical than a simple bag, in addition to being reusable unlike the bag which will dry everything very quickly.

The Scythe Ashura 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 and dimensions the Scythe Ashura is average with a maximum height of 16.1 cm for 14.5 cm wide and 6.5 cm deep (9 cm with the fan) for 887g (750g without the fan), it will be necessary when even, like all coolers equipped with a 14cm fan, pay attention to the compatibility of the first PCIe port attached to the socket, we will see that later!

50 aluminum fins are present which represents a large dissipation surface, 6 copper calloducts will be responsible for transferring the heat from the base to these small fins. The Glidestream 14 cm fan rotates at a maximum speed of 1300 RPM for at least 500 RPM (see less in practice), which should ensure very low noise to the minimum and very contained to the maximum while keeping a minimum of ventilation.

The Scythe Ashura can be found around 39 € and guaranteed for 2 years which should interest many of you, if the performance is up to par, we will see that below but for now, the assembly!

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


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


Then place the screws that will attach the back plate:


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:


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


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:


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 and place it so as to have the “short” side of the cooler on the memory side in order to take advantage flawless memory compatibility:


Once you have placed the cooler like that you have to put the fixing bar at the base of the cooler and start screwing, be careful however you have to proceed alternately and especially not screw a screw as far as possible and then pass on the other under penalty of having completely delusional temperatures. 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.


Once fixed, all you have to do is place the fan on the radiator using 2 of the 4 fasteners provided and then connect it to the motherboard, like this:


And There you go! The Scythe Ashura is fully operational, let’s take a look at the memory and PCIe compatibility, often problematic with coolers equipped with a 14cm fan.

Memory / PCIE compatibility


Regarding memory, no problem to deplore, the Scythe Ashura will be perfectly compatible with all memory modules on the market.


On the other hand at the level of the first PCIe port it is more problematic, although on the photo we see that the cooler stops just in front of the port I strongly advise against installing a graphics card there, indeed as long as a screw protrudes on the board or it is not perfectly straight there will be a risk of a short circuit, unless a non-conductive material is added in between.

The test platform

The Scythe Ashura 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 desk (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 Mugen Max (tested here)

The temperatures


The performance of the Scythe Ashura is very good, in PWM we arrive at an average of 54 ° for 50 ° in 12V and 70 ° in 5V, which means that the processor will in no case be overheated. The difference between 12V and 5V is quite large because the fan once at minimum only turns at 330RPM, which is really very low and therefore it does not stir a lot of air but still maintains the Core i7. 875K slightly overclocked to a very reasonable temperature!
We can also see that the results are in all respects identical to the Mugen MAX tested previously, and the similarities will not end there because the fan is identical, so the noise pollution will be too, let’s see see that!

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.


At least the Scythe Mugen Max is very quiet and it will not bother you too much, only a slight noise of the motor is heard when you stick your ear on it, nothing serious however because this noise disappears immediately once the ear at 50 cm. On the other hand, the fan will not be forgotten, it cannot be qualified as silent but only the circulated air is heard, there will be no engine noise or friction which is still to be noted. . The PWM mode is a real credit to the GlideStream with a sound level of 34dB, which will certainly be much lower than the noise of other components under load, so will be really inaudible once in a tower.


Here we are at the end of this test, what to say about this Scythe Ashura?
Scythe, which aims to make efficient, silent and accessible coolers has once again not missed the boat with the Ashura, indeed the build quality is very good but without frills which would have increased the price for in the end that aesthetic changes (copper in nickel-plated calloducts, for example). The performances are there and in direct correlation with the noise pollution, in 5V the Ashura is inaudible but remains however able to cool a processor without worries while in 12V the temperatures are very good at the cost of much more noise pollution. high, the PWM mode will be preferred to have the best of both worlds.

The only small point that I could blame the Ashura for, and this is the case with many coolers with 14cm fan, is the compatibility with the first PCIE port, although it is technically possible to install a card there it will not be necessary not that anything exceeds even if only a millimeter otherwise it will affect the cooler, in other words that the port is condemned. Another small downside concerning the assembly, it would have been good practice to put a stopper at the level of the fixing screws of the central plate, so that there would be no risk of over-tightening.

Offered at a price of around 39 € it is clear that Scythe signs here an excellent cooler once again, combining performance and silence for a low price, if you are looking for a cooler for your gamer config equipped with a minimum overclocked processor but that premium coolers over 60 € are not possible then the Scythe Ashura will give you complete satisfaction!


  • Performances
  • Noise pollution in PWM / 5V
  • Memory compatibility
  • Good finish
  • Price


  • Noisy in 12V
  • First PCIE port blocked
  • Do not force too much

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