Every enthusiast knows just how important a CPU cooler is. Overclockers alike know that it is one of the most important components to a computer, just as important as the motherboard, processor, and even the power supply. It’s the component that can decide for you just where the future of your CPU lies and just what kind of overclock you can expect. Choosing the correct cooler can make your desired overclock plausible; choosing a low budget cooler will simply get you by at “safe” temperatures. Then there are other coolers meant for looks but have hopes of cooling the CPU quite well, depending on the design that is. This is where the new Scythe Kama Angle CPU Cooler comes into play. The Scythe Kama Angle has a unique "V" shape design that can be mounted in four different ways and the fan is able to be installed in three different locations. Scythe, as always, comes up with some of the most clever CPU coolers and the Kama Angle is no surprise in terms of flexibility and uniqueness.



Closer Look:

The packaging of the cooler was cluttered with information on every side of the package. It shares the English language and Japanese language on every side as well. On the front of the package you are able to get a glance of the cooler with the fan pre-installed, and looking at the top left hand corner you will see the “Quad Core Ready” sign. On the top right hand corner you will see the different platforms that the Scythe Kama Angle can be installed on. Under that there are four diagrams, an Airflow Vector diagram, Multi Fan Mount Structure, 4-Way Mounting, and a Wide Range diagram. The right side of the package describes the diagrams more in depth. On the left side of the package you can see the base of the cooler and the copper heatpipes, as well as how the cooler will look once it has its mounting hardware installed. On the back of the package you will see the cooler's warranty policy.






Once you open up the package, the first thing you will see is the included 120mm fan. Once you open the lid that lies beneath the fan you will see the heatsink, as well as the ends of heatpipes.



Along with the fan and cooler you get a box filled with accessories. Inside the cardboard box are four screws, mounting clips for both Intel and AMD, thermal compound, and an installation manual.


Now it's time to inspect the CPU cooler.

Closer Look:

The overall design of the cooler is unique; rather than a tower design, Scythe and Quiet PC have come up with an unusual "V" shaped cooler to provide, as per the previously mentioned diagrams name, wide range cooling. The Scythe Kama Angle is made up of 60 fins that are as thin as can be for improved air-flow. With the fan installed in the gap of the cooler, airflow can become effective depending on what direction you install the cooler. With that said, the cooler is able to be installed four different ways, as well as the fan having three different locations for installation. The cooler is also capable of holding three fans for some serious cooling. With multiple installations for the fan and the cooler itself, the angled shape works in sync with the system for maximum airflow in the case. The cooler weighs in at 640g so it is somewhat heavy. This is where the infamous push-pin system from Intel comes in handy (since there is no back plate). No matter how annoying push-pins are, they can definitely hold down a cooler.  













With the fan installed, the cooler is ready to dispense of any heat generated, and if one fan isn't enough you can always add two more! The person can be creative as to how they want their airflow.


The fan included with the cooler is a 120mm PWM fan rated at 12v. A PWM fan means the connector has four wires; three of the wires are used to power the fan, while the fourth wire is used to control the fan via software (while reviewing, I used Speedfan 4.35 to speed up and slow down the fan). The noise level is between 6.4dBA~24dBA.  



The Scythe Kama Angle has four copper heatpipes that are relatively spaced out, allowing heat to disperse quicker and more efficiently. The four copper heatpipes connect to a nickle plated copper base that has a very nice, mirror like, finer print galore finish to it.



Space is a factor with the Scythe Kama Angle if you are in a smaller chassis, however the four position mounting system is a great feature for the cooler. Installation of the Kama was interesting. The sides of the heatsink along with the orientation of the push pins turned out to present some challenges with the limited space I had with it in this case. It took a while but alas, the Kama was ready to go!


After inspecting the cooler I am ready to see how well it performs.

To properly test the Scythe Kama Angle CPU cooler, I will record the temperatures of the processor during its idle period (little to no CPU usage) and at load (100% CPU usage). I will run the computer for 30 minutes without any stress before I gather the maximum idle temperatures. To gather load temperatures I will use Prime95 V25.8 (Small FFts) and have it run it for 30 minutes to gather the maximum load temperature. I will use Real Temp 2.70 to monitor the maximum idle and load temperatures of the processors cores. For stock testing, the CPU will run at its default clock speeds (2.53GHz) and default voltages. For the overclocked tests I will use a multiplier of 8 and a front side bus of 400 to give me 3.2GHz, the vCore used will be 1.34V. All temperatures will be taken in degrees Celsius.



Comparison Heatsinks:





The Scythe Kama Angle CPU cooler performed exceedingly well, and displayed slight differences with the Xigmatek HDT-S1283 and the Reeven RCCT CPU coolers. It fared well in the idle overclock testing, only to come out in third place in the load overclocked tests. Still, temperatures remained in the safe zone throughout the testing.


The Scythe Kama Angle was quite an odd looking cooler, to say the least, but its "V" shaped design was a success. The performance is where it should be and definitely put a good fight against the large Xigmatek HDT-S1283 cooler. The cooler was also one of the quietest CPU coolers that I have come across. This shouldn't come as a surprise though as Scythe is known for its silent coolers. An impressive feature about this cooler is its flexibility. First of all, the cooler can be mounted in four different directions, providing airflow to certain chosen areas. This also makes the cooler quite versatile and able to be installed on countless motherboards without any problems. The fan can also be installed in three different locations on the cooler. What I didn’t enjoy too much though was the installation. The corners of the heatsink's edge do make it difficult to install using the push-pin since there is not much room for your fingers to push and twist. Other than that, the Scythe Kama Angle is a top performer for either the average Joe or the enthusiast.

Overall, I was pleased with the cooler's design and performance but most of all, I liked how quiet it was even with the fan at full speed. I have no problem recommending this cooler to either the overclocking novice, anyone looking for a quiet system, or for someone just wanting a cooler that will get them through the day at safe temperatures.
