Scythe Ninja 4 CPU Cooler Review, another CPU cooler today from the well established, cooling brand Scythe. The company has been producing visually unique and able products for years now. Back in 2005 the original Ninja launched, and we’ve seen many revisions and sub-versions of it since, mini and all copper to name just a few
Today we explore the Ninja 4, as you would imagine the Ninja 4 has been tweaked and refined for the modern platform. Pricing on the day of review is £40. Be sure to check HERE for other regions. Which is about the norm for such a product.

Three-dimensional Multiple Airflow Pass-through Structure
By introducing our new T-M.A.P.S technology for the Ninja 4, we were able to increase the cooling capacity compared to previous models based on the older M.A.P.S lamellar structure. The clever arrangement of the cooling fins allows the usage of an additional pair of fins without suffering negative effects to weight or height of the heatsink and optimizes the cooling power in the lower speed range of the supplied fan.
Glide Stream 120 mm PWM Fan
The enclosed 120mm fan comes from the Glide- Stream PWM series. This new model offers the ability to adjust the maximum fan speed in 3 settings via a slide switch, allowing the user to choose between extremely silent operation or maximum cooling power.
Flexible Fan Mounting
Inspired by his predecessors, the Ninja 4 offers the option to install the fan on all four sides of the heatsink. This allows for very effective integration into air flow of the case. To further increase the performance, a second fan* can be installed by using the included additional pair of fan clips.
User-friendly Installation System
The proven HPMS (Hyper Precision Mounting System) mounting system is also to be found in Ninja 4 again . The mounting of the cooler is much easier. It requires fewer installation steps and time without compromising reliability.

[Packaging and Bundle]
Packaging for the Ninja is styled well to match the product name, is all black with none other than a ninja on the front side. Below it, a glimpse of the product. The sides detail the key specifications, and size, of the Ninja cooler. Nothing for English users on the backside of the box
Inside, you’ll find all the necessary mounting kit for AMD and Intel, bolts and such. A welcome addition is the screwdriver, something very brands offer the user. The user manual is clear, concise and helpful. Covering all the major socket installation processes.
The Ninja 4 is the latest model in the Ninja CPU Cooler Series, developed for uncompromising performance. It features the new T-M.A.P.S technology, an optimized alignment of heatpipes, and the back-plate based Hyper Precision Mounting System (H.P.M.S) for firm mounting and easy installation procedure. These improvements and a special, adjustable Glide Stream 120mm PWM fan result in an increased cooling performance while reducing the weight compared to his predecessor. Also the design of the heat-sink allows fan mounting on all four sides. This enables the optimal integration of the Ninja 4 in the air flow of the pc-case and reduces turbulence and the emergence of hotspots
Dimension are 130 x 155 x 153 (W H D), and firsts impression are great. The cooler looks extremely capable that’s for sure, the shape looks familiar right? I couldn’t help but think it was strikingly similar to a ninja star, which is complimented further with a shuriken embossed on top!.
What’s unique about the product, because each side is the same as the rest, is the ability to install the fan(s) on any side you wish. Something I’ve never seen elsewhere!
The amount of heatpipes here on the Ninja 4 are mind-boggling, what’s brilliant though is the layout underneath. It will become more meaningful once we cover the install, but clearance appears impressive.
The Glidestream 120mm fan, features a 3 mode switch, allowing the user to configure the fan as they wish. Control the fan from silent to performance mode (Low, Medium or High)

The Ninja 4 uses a bracket and brace system, that couples up with a backplate. It’s actually the very same mount we saw on the Grand Kama 3 and the MUGEN MAX recently.
Because these coolers are all on the larger side, I would highly recommend removing your motherboard for the installation. Scythe do provide a spanner for the install, but I found using the free screwdriver to be just as effective, easier actually.
- The backplate is put into place,
- 4 pillars with washers fasten it into place.
- Next you take the mounting arms and lay them across the pillars,
- finally secure them into place with the provided screws.
Align the mounting brace across the heatsink base. Add thermal paste, and lower the cooler down into position. Make use of the elongated screwdriver that scythe provide and lock it down into place with two bolts..
As I said above, you’ll want your motherboard outside of the case as the brace that sits on top of the heatsink, does rock like a see-saw until fixed down. Also adding the 4 pin fan header may be difficult if you don’t
I grade the installation process on a scale of 1-10. With 10 being the most difficult, this would be a 4, it takes time and patience but with care, nobody should struggle
[Clearance and observations]
A tower cooler like this tends to have issues with RAM clearance and the Ninja 4 does overhang across the first DIMM slot.. We installed standard-sized modules, under the Ninja 4 wth ZERO issues.
The limit is 40mm, but the Fan uses traditional fan clips, (easier than most) so you can just raise it up when needed. Or In a worst case scenario, you could always install the fan on one of the other three sides!

CPU coolers and test method is an area that causes much confusion and debate. We should point out that many sites test in different ways, but the majority share the same core idea that a simple math equation should be used. So that a consistent value can be recorded and re-used against other products
This simple equation of [recorded result] [minus] [ambient room temperature] = Delta
This test method simply means no matter how warm or cool the testing room is, the data is comparable. There will always be a degree of error in such testing. There are so many variables such airflow, testing location and such. So we perform all our testing on the same hardware and in the same location.
- Our procedure is to fit the cooler and allow a 24 hour period before any testing, allowing the thermal paste to settle. The system is booted and allowed to sit idle for 15 minutes. We take our first recording. Then using a selection of software forcing the CPU to run at 100% load. We then take our load temperatures.
- This process is repeated 3 times and the results are converted to an average.
- We provide delta temperature [Load temperatures minus ambient room temperature].
- This allows us to provide consistent results no matter the room temperature.
Many factors can skew results and to ensure accuracy we repeat all of the above three further times. Including refitting the cooler, this compensates for factors such as burn in time, amount of thermal paste and such.
To keep things neat and easier to read, we no longer provide idle or ambient numbers, only load delta results.
I must point out that we do not manipulate and force the fan to run at 100%, it is something we had considered in the past and if we had done, most of the products in the chart would appear to have better results.
However what we present is a fair representation of how a product will perform out of the box. With this in mind what we tend to find, in our stock testing is that the fan(S) does not always hit 100%.
* Our test CPU is ran at default auto clocks and voltage for stock testing. For overclocking it’s not the best around and requires 1.375 volts to operate at 4.6 GHz. All results shown are at these settings unless otherwise stated*
The test that matters more for Overclockers… we applied a heavy overclock, which requires lots of vcore. Thermal ability was similar the to recently reviewed Grand Kama 3 (more expensive), and lagging behind the Mugen MAX.
The important question to answer, next, was it loud?
The low starting RPM of the fan results in whisper quiet noise output for most of the time, under full load the noise is apparent but certainly not distracting at all
The Ninja made waves when it debuted back in 2005, I never had the opportunity to use one, but I’ve researched the transition of the revisions and sub models since. It’s clear that the core design is a winner because 10 years later it’s still viable. Much has changed in terms of small refinements to the fin arrangement, materials used, but it’s still the great product it was, just more able!
CPU Coolers with a footprint like the Ninja 4 tend to be difficult to install, and rairly offer decent ram clearance. The Ninja 4 despite its size, has neither of this issues for those using generic sized ram. I measured a total of 40mm of space, between board and base of heatsink.
The performance under stock CPU conditions was very good, and outputted hardly any noise at all, you’ll hardly not even notice it. Once we tested the Cooler with an overclocked CPU, the product did fall behind the MUGEN MAX, but ranked close to the KAMA 3, which is more expensive. Noise even at its max, was very acceptable for a 120mm fan.
The Ninja 4 delivers very fair performance, both in thermal ability and noise emission. Based on everything we’ve seen today, factoring in price too. I must offer our “Silver Award”, the only niggle is RAM clearance, which the 40mm of space should be enough for most users. Ideally I’d like to see it improved in future models.
