A decade ago, the third party CPU cooler food market was very different, dominated
by down-blowing models of various shapes and sizes. Heatpipes were in use, but
once again, they were generally employed in tralatitious top-down heatsinks. The now
ubiquitous tower heatsink may possess been started aside Scythe with the Heatlane
NCU-1000, a niche product using flat heatpipes to attain fanless operation
in 2003. The Coolermaster Hyper
6 of mid-2004 English hawthorn have been the first tower Element 108 adopted specifically for
high carrying into action constrained air CPU temperature reduction. By the meter the underived Scythe
Ninja appeared in mid 2005, tower heatsinks had get along commonplace. Uncommon
was the Ninja's compounding of huge sizing (at the time), rather wide separated
fins, and fantabulous performance with or without fans. SPCR's review articl of its superb
performance with minimal airflow bolstered the Ninja to a new level of popularity
steady with DIYers unsettled by its size of it.
Subsequent versions of the Ninja failed to reach the same level of functioning
as the original. Throughout the product's account, the mounting system was considered
by many to be subpar. Initially, Scythe unbroken victimization a socket 478 way retention
mechanism, adapting later sockets to use this standard. Considering the substantial
weight and height of the heatsink, aside from the slightly more massive all-fuzz
variant, not including a backplate was a mistake. Scythe finally provided a
backplate in the climb system of the Ninja 3 but it had a troublesome installation
routine that required flipping the motherboard upside down. The Ninja 3's
base had a slenderly concave profile which made IT difficult to achieve proper
mating with the processor.
The Scythe Ninja 4.
By today's standards, the Ninja 4 is just now another big tug, but the name itself
may be enough to be competitive. This Ninja is one of a new breed from Scythe
that have breathed new life into the brand. Key is a Modern mounting connive
similar to those adopted by all the top off tier heatsink manufacturers like Noctua,
Prolimatech, and Thermalright.
The heatsink itself is non that different from previous iterations, featuring
a six heatpipe design (U-shaped for 12 heat paths), a broad stack of loosely
unreal aluminum fins, and a square symmetrical shape that allows users to
primed 120 mm fans on any side. Older Ninjas had slits at the corners of the fin-batch
in part to access the pushpins to mount the heatsink but this is nobelium thirster requisite.
The new design with slits at the center of each side is more spellbinding and
the top fin has semi-reflecting gleam. The copper heatpipes have also been plated
over with Ni, giving the newly Ninja an altogether shinier look. The latest
model is slightly shorter, but also wider on all side, giving the deceptio
of added bulk, when in fact it's 130 grams lighter than its predecessor.

Accessories.
If you've used one of Scythe's latest coolers or read reviews of them, the
mounting hardware should front well-known. Although AMD support is listed, the
necessary clips were strangely absent in our sample — this appears to have
been an oversight. A screwdriver is provided atomic number 3 is a miniscule wrick to tighten up
the screws/bolts further. Also enclosed are installation operating instructions, a lowly
tube of thermal colonial, and two sets of wire fan clips.

PHYSICAL Inside information
The Scythe Ninja 4 is poised of 36 aluminum fins rubbing-fit to 6 x 6 mm
thick nickel-plated pig heatpipes which in turn are soldered to a nickel-plated
copper base. By my measurements, the heatsink's dimensions are 13.0 x 13.0 x
15.5 cm (W x D x H) and its exercising weight is 790 grams. The stock fan adds an additional
120 grams to it total, but it doesn't increase the tank's stature.
On average, the heatsink's fins are 0.43 millimetre boneheaded and spaced 2.57 mm apart. This loose configuration is typically employed to reduce resistance to airflow which helps thermal performance with under speed fans. Standing 15.5 cm magniloquent, it's slightly shorter than most tower coolers.
The fin good deal is cut up into four identical sections in parliamentary law to allow screwdriver access to finish the facility procedure. At the top, a ninja mavin is imprinted at the center with each tiptoe bordered by the tops of the heatpipes. Compared to the Ninja 3, the heatpipes are arranged encourage away from the center.
The footprint is 13.0 x 13.0 cm so the heatsink isn't overly wide but information technology does continue somewhat past the included 120 mm fan on each side.
The base has a silky surface with both straight and circular machine marks visible to the naked eye. Like most of the Scythe's Recent epoch heatsinks, the surface is convex with a pinprick sized apex at the centre.
The stock fan is a 120 mm GlideStream, easily distinctive aside its scalloped vane intent. This is a 1500 RPM model but there is a control switch intrinsic that crapper reduce the maximum speed to 1150 or 800 Revolutions per minute.
INSTALLATION
The most severe vista of installation is firm, upper limit contact
between the base and the C.P.U. heatspreader for efficient hotness conduction. Ideally
it should also be a simple procedure with the user having to handle as few pieces
of hardware as doable.
The Ninja 4 utilizes the same updated arrangement used previously by Scythe with their most recent crop of coolers like the Mugen Max, Mugen 4, and Kotetsu. It's a similar method to otherwise big name manufacturers and involves assembling a metal mounting rig around the CPU socket and pinning the heatsink thereto using a thick crossbeam over the base of the heatsink to apply downward pressure systematic to guarantee worthy contact
Installation kit collected without the heatsink.
Mounting platform installed.
Fully mounted. The fan clips attach fairly snugly to the outer mounting holes which makes it very difficult to confiscate 140 mm fans imputable their larger frame size.
With the buff centralised, there is 8 mm of clearance above our bare DIMMs.
The buff hangs finished iii of our LGA1366 motherboard's six memory slots so RAM with tall heatspreaders may be a rootage of incumbranc. 46 mm separates the bottom fin of the heatsink and the airfoil of the motherboard which is sufficiency to well accommodate most VRM heatsinks.
The imprint left behind by the heatsink is not equal but it is very faint at the center indicating good contact. A good mating on with solid stress pushes most of the thermal dissected out to the sides.

Noise measurements are ready-made with the fans powered from a separate, fanless scheme. Load testing was accomplished using Prime95 to stress the processor, and the
graph function in SpeedFan was used to ensure that the burden temperature is stable
for at least ten minutes. The temperature recorded is the highest single core
reading. The stock fans were tried and true at various voltages to represent a good
cross-section of airflow and noise performance.
The ambient conditions during testing were 10~11 dBA and 21~23°C.

Aside from the three speed switch and slightly higher 1500 Rev spinning top speed, the stock fan is similar to the GlideStream role model that ships with the Scythe Kotetsu and Mugen 4. This line of fans is characterized aside a modest hub, struts curved against the curvature of the fan blades, and the flat tips of the blades' leading edges.

On PWM control, our sample is able to go down clear to 340 RPM, slow enough that it effectively gets below our chamber's noise floor. At the opposite end of the spectrum, it produces a precise loud 30 dBA@1m at sperm-filled speed, so there's a wide variety of speeds to choose from depending on how practically noise you're disposed to tolerate.
The three speed alternate entirely limits the utmost speed, to 1500, 1150 operating theater 800
RPM. It is probably most profitable if the fan header lacks PWM control, or if you
lie with your system of rules bequeath never require the cooling power of the fan on the far side the
set off speeds.
The GlideStream lacks the silky smooth acoustics of its Slip Stream predecessor
only it's a decent 120 mm fan. This particular try out is not as satisfying to the
ear as early, slower speed samples. Information technology's somewhat smooth only buzzy at high
speeds which is typical for a sleeve bearing good example. As the fan slows, IT develops
a moderate hum, high inclined at first, and then lowering as speed decreases. At
precise low speeds, there is less turbulence, making an underlying clickiness more
broad. These noises probably aren't audible when the heatsink/fan is mounted
within a case, though, so they'atomic number 75 niggling.
TEST RESULTS
NOTE: Our Noctua NF-P14 140 millimeter reference sports fan has been retired A
it is zero longer being sold, and we're down to cardinal unexpendable samples. And then
ahead they break, we're devising the premptive move of replacing them with the
Scythe GlideStream 140-M (1200 RPM 3-pin example) which International Relations and Security Network't quieter or

The Ninja 4 performs incredibly well on our test platform, keeping the thermal rise at 40°C or lower at every tested fan speed. Moreover, the performance changes very short as the fan speed decreases, with a total spread of just 6°C between 100% and 30% on PWM control. With the shopworn fan, the ice chest appears to hit its sweet post at approximately 50% speed, which is just under the 20 dBA threshold that I consider quiet. Performance is even comely at 30%, with the noise level approaching unperceivable.
Temperatures actually start up when our larger reference sports fan is victimised, with the GlideStream 140-M causing a ~3°C penalty at equivalent weight randomness levels, but this is fiddling Eastern Samoa we just need this information to compare with past/tense heatsinks using the same fan(s). Double upwards along fans is marginally more effective at moderate speeds, simply a 3°C betterment can be enjoyed at very modest speeds.

The Ninja 4 ISN't as conspicuous with dual fans, simply stock-still first-class, inside
a stone throw's away from being one of the very best.
MP3 SOUND RECORDINGS
These recordings were made with a high
solution, lab quality, digital recording system inside SPCR's
possess 11 dBA ambient anechoic chamber, then regenerate to Weak 128kbps
encoded MP3s. We've listened long and laborious to ensure in that respect is atomic number 102 sounding degradation
from the original WAV files to these MP3s. They represent a quick snapshot of
what we heard during the review.
These recordings are planned to give you an idea of how the product sounds
in actual use — peerless meter is a reasonable veritable outdistance 'tween a computer
or computer component and your pinna. The recording contains stretches of ambient
noise that you can use to judge the proportionate loudness of the subject. Make up aware
that very quiet subjects may non be audible — if we couldn't hear it from
one meter, chances are we couldn't memorialise it either!
The recording starts with 5 second segments of way ambiance, so the fan
at respective levels. For the near realistic results, set the volume so that
the starting ambient flat is precisely hardly audible, then don't change the volume
setting again.

FINAL THOUGHTS
The Scythe Ninja went through numerous redesigns and revisions that mostly
underperformed, failing to live up to the landmark debut. A to the full decade later,
iteration number four finally deserves as a good deal herald A the original. By a
hair, the Ninja 4 is the high-grade single devotee tower CPU cooler we've time-tested up to now,
and the stylish success story for the revived Japanese manufacturer. The Ninja
4 beats out its predecessor by a substantial 6°C~10°C depending on the
noise level, steady though the two are non that different physically. The newer
model has similar fin spacing, a slightly lighter and bigger personify, and nickel-plated
heatpipes but these changes are probably too small to be responsible such
a dramatic performance improvement.
In the Ninja 3 review, I made tone of the slightly recessed base and the unwell
designed mounting system. Scythe addressed both of these issues aside making the
base slightly broken-backed, and using a new modern assembly scheme that exerts greater
strength directly over the mean, creating prime contact with the CPU surface.
This climb formula has been applied to all of Scythe's latest coolers, and
not coincidentally, most of them now occupy overflowing positions on our cooling performance
charts.
The Ninja 4 is currently selling for ~America$50, a very modest sum for such
a high-pitched performance tank. The exclusive achievable drawback is compatibility, equally it
does string up over memory slots which will causal agent interference issues with oversized
memory heatspreaders. In person, I always select memory of overmodest size, but
if you're stuck with tall ones, consider the starting time design of the Mugen Max
OR the thin Kotetsu as alternatives. On with the Ninja 4, they offer up prime minister
performance at a fairish price.
Our thanks to Scythe
for the Ninja 4 CPU cooler sample.
