Have you recently been looking for a new cooler for your CPU? Maybe you are just begining the exciting adventure into the overclocking scene or perhaps you're a seasoned overclocker and you are looking for an upgrade. Well with the release of the 45nm processors, many people have been looking for new coolers to keep up with the excessive amount of heat that is given off by these power houses, especially with the ever growing popularity of quad core processors. What ever your reason, you may want to check out the Scythe Ninja 2. When I hear a name like that, I think about how silent ninjas are andI wonder if this cooler will live up to its name. Well instead of just talking about the Scythe Ninja 2, lets take a look at exactly what this thing can do!

Closer Look:  

When it comes to the looks of the packaging Scythe likes to use, they usea very uncommon and busy package. The front of the box shows a picture of the Ninja 2 Cooler in a fan-less mode. The cooler looks very interesting... There are three heatpipes running down two adjacent sides, which is something that I have not seen yet. The top right hand corner of the package lists the different sockets that the cooler is able to be mounted on top of and there are both AMD and Intel sockets. There is a 5% improved temperature in fan less mode and a 15% improved temperature with the fan installed over the old Scythe Ninja cooler. There is a badge on the right hand side of the package that lets you know that the cooler supports Quad Core processors. The bottom of the package is where you are going to see the Scythe Ninja 2 CPU Cooler logo, it again, like  the rest of the package, is very busy and grabs your attention. The back of the package is where you are going to find all of the warranty information that you are going to need to know about the cooler if you need to replace it either inside or outside of Japan. On another side is where you are going to be able to find all of the specifications of the cooler.




When you open up the package, you are going to see that Scythe included their own 120mm fan for you to mount on the Scythe Ninja 2 cooler. You will also see the Ninja 2 itself and a white box containing the necessary accessories. They include the three different socket mounting clips, LGA775, AMD 754/939/940/AM2 and Intel 478, a pair of mounting clips for you to mount the fan to the cooler and four small screws so you are able to mount the clip of your choice. Scythe also decided to include a little bit of thermal compound for you just incase you are out or don't have any.  


Well now we know what the packaging for the Scythe Ninja 2 looks like and what comes inside of the package. Now it's time to take an even closer look at the cooler itself, see exactly how the cooler is made and what makes it stand out from other coolers on the market.  

Closer Look:  

The Scythe Ninja 2 has a very distinctive design to it. All four sides are the same size and look exactly the same, which to me somewhat resembles a large skyscraper or tower. Not only are all of the fins on the cooler cut and shaped to look the same on all four sides, the base and the heatpipes are also designed this way. There are a total of three heatpipes on each side that run from the top of the cooler on one side, run through the base and extend through the top of the opposite side of the cooler, passing between all 26 of the fins. This gives the cooler a total of six heatpipes that have been forged in the design of the cooler. I am curious to see how effective this design is going to work, especially with a quad core that will be giving off quite a bit of heat. You can see at the base that Scythe has placed a small heatsink to help pull some more of the heat off of the base of the cooler and distribute it through the fins of the cooler.  









The next thing that I want to take a quick look at is the way that the cooler's 120mm fan is going to be installed. Scythe has taken the recently popular fan clip idea and used it with the Ninja 2. There are two clips with hooks on each end that go into the holes in the corners of the fan. These wrap around and go into the slit that is cut into the fins of the heatsink. This enables you to place it where ever your motherboard layout allows.




The last detail that I want to explore is the mounting hardware for the Intel LGA775 socket, as this is the socket used by my testing setup. The way that Scythe has setup their multi-platform design is quite simple. On the bottom of the cooler there are four small screw holes that you are able to screw one of the mounting brackets to and make it secure. I do want to mention that when you are installing the bracket, make sure you remove the protective film off of the cooler's base as it will prove to be difficult to do so after the mounting hardware has been screwed on.



Ok, so we know what it looks like, how its built and how we need to prep it for installation. What we still do not fully know is the specifications on the cooler. Let's fix that shall we?

To properly test the Scythe Ninja 2 CPU Cooler, I will be monitoring the highest temperature of the processor at Idle (little to no CPU usage) and Full Load  (100% CPU usage). My idle test will be done by running the computer for thirty minutes and recording the maximum temperature during that time. I will be using OCCT:PK to simulate a full load. I will run a torture test for thirty minutes with the mixed (CPU and RAM) mode turned on and gather the maximum temperature during this time. The temperature monitoring software that I will be using is Real Temp 2.60 as it reads all four cores, documents the maximum temperature for a period until you reset it and most importantly reads the 45nm processors tempeartures correctly. I will be using the four maximim temperatures that were given off during the test and taking the average of the four cores. The stock test will be done using all of the stock settings for the Q9450 @ 2666MHz. During the overclocked tests, I will be using 410MHz FSB with an 8x Multiplier to give me 3280MHz overclocked speed, with a Vcore of 1.34 Volts. All of the temperatures are measured in degrees Celsius.

Testing Setup:


Comparison Heatsinks:

NOTE: Some of the listed heatsinks were originally tested using an E6600, I recently retested and gathered new data after the switch from the E6600 to the Q9450. The new temperatures are represented in the graphs below.






As you can see in the graphs above, the Scythe Ninja 2 did very well when it was put up against the other coolers, it was able to take second place, only beaten by the Thermalright Ultra 120 Extreme in all four tests.



What is there to say about the Scythe Ninja 2 besides the fact that it not only looks good but can perform quite well! I was quite surprised when it came down to the testing, that the Scythe Ninja 2 CPU cooler was only beaten by the Thermalright Ultra 120 Extreme. Scythe has done something quite well with the release of the Ninja 2, as it not only performs well, but it also runs at relatively silent. I was unable to hear the supplied 120mm fan over the my HD4850 stock cooling or over the other fans installed inside of the case. I was still disappointed to see that Scythe did not include a PWM feature with the fan. Since the fan is already quiet, slowing it down isn't really necessary, but a PWM feature would be nice to have as an alert if your CPU fan stops.

I really liked the large base of the Ninja 2, this helps with the heat transfer from the processor and to the six heat pipes. The 26 fins quickly carry heat away from the heatpipes (Which allows the heatpipes to quickly carry away heat from your CPU). Speaking of the size of the cooler, you do need to be careful. I was unable to place the fan on the cooler by the RAM sticks due to height restrictions, I ended up having to place it on the other side, sucking the air through the fins instead of blowing it onto the fins. However this obviously depends on the layout of your motherboard.

The multi-platform design allows for a diverse range of usage. For those who use both AMD and Intel systems, this could come handy. The cooler features a tool-less installation once the mounting clips are installed to the base of the Ninja 2. This helps with the time it takes for you to install the cooler on your processor and also allows you to install it while the motherboard is still in the case. I would strongly suggest this cooler to someone who is looking for a new cooler to cool their overclocked CPU.
