Have you been looking for a new cooler for your processor? Are you big into overclocking and you want the most efficient way to cool your overclocked dual or quad core CPU? Maybe you are not ready to venture over into the side of extreme cooling, and want to stick with air cooling. If so, you are in luck, Cooler Master has just released their V8 CPU Cooler. This cooler is like nothing else that is currently out on the market. Its huge (No surprise there), can be used with multiple platforms (LGA775, AMD 754,939,940and AM2), and looks like it can cool anything you can throw at it with 180 watts worth of capacity. The Cooler Master V8 Cooler features four separate fin arrays with a center mounted fan to maximize it's cooling abilities. I am interested to see exactly how well this cooler works and how well it's going to cool an overclocked Intel quad-core CPU. Will it be the one to finally pull the TRUE off it's pedestal and become the new king of the hill, or will it be another pretender with high expectations?

Closer Look:

The packaging for the cooler is very simplistic in looks, as it is completley black in color with a very limited amount of words and pictures, letting the consumer know exactly what they want to know about the cooler. The front of the packaging is where you to find the main picture of the Cooler Master V8 CPU Cooler, along with the Cooler Master badge in the upper left hand corner of the package. At the bottom of the package the V8 logo appears, along with the slogan "Experience the power of V8," letting you know that the cooler is very powerful. Above the slogan, you are also going to see that the cooler is rated to cool 180W, more than enough for your overclocked CPU! When you take a look at the back of the cooler you'll find all of the specifications for the Cooler Master V8 CPU Cooler, along with the main features Cooler Master wants you to know about. The two sides of the V8's packaging are very simple--they show the V8 logo as well as a small picture of the cooler itself. Below the logo on the sides are the logos for the processors that it has been rated to cool. Well, enough talk about the packaging, let's open her up and see if she's a beauty like the box makes her out to be.




Now that we have seen the package for the Cooler Master V8, I am interested in seeing how the cooler was kept in place during the shipping process, and what she looks like. When you open the package up, the cooler is in a molded plastic package to keep it from moving around during the shipping process, as well as to help prevent any fins from being damaged. Included with the cooler are the warranty card, a user manual and an accessory box.


Inside of the white accessory box, you find everything that is needed for the installation of the Cooler Master V8 CPU Cooler. You may be wondering what comes in that package.  Well, when you open it up, you are going to see that there is a back plate for the Intel Socket 775 CPU, one of the more common CPU sockets on the market right now, and there is a bag that contains everything else that you are going to need. Inside of this bag, you are going to find another smaller bag that contains all of the screws/bolts to mount the cooler with, a tube of thermal paste, two mounting brackets for the Socket 775, as well as the mounting bracket and back plate for the AMD side of things.  




Now that we know exactly what the Cooler Master V8's package looks like and what comes packaged with it, we are ready to take one of the first looks at the Cooler Master V8 CPU Cooler.

Closer Look:  

When we get the Cooler Master V8 pulled out of its packaging, you'll notice that it is very large, as well as very complicated looking. The front, as well as the back, look very similar.  The two sides of the cooler look very similar to each other, also. Taking a look at the front and the back, you are able to see that the cooler is made up of four different aluminum fin arrays, which will allow more room for heat to be removed from the processor. You can also see that there is a 120mm fan located in the center of the cooler to help cool the fins from the center. When you take a look at the two sides of the cooler, you see exactly how the different fin arrays are set up to create a very fine space for air to be pulled or pushed out from. From this side, you are also able to see how the heatpipes are set up.  There are two going to the fin arrays off to the side, and four going to the two inner fin arrays.








The top of the cooler has a large black piece of plastic that covers the entire top, this is to help keep the air flowing in the direction that it needs to, as well as to keep the center fan in place. The Cooler Master badge is in the center, with the V8 logo off to the bottom. The way it's setup makes it look like the plastic protective covers over modern day motors in cars, hence the name, V8. The bottom of the cooler is where all of the heatpipes connect to the base, as well as where the mounting brackets are screwed in.  The base of the cooler looks very flat and has been polished.




The next part of the cooler that I want to take a nice good look at is the active cooling solution, the large 120mm fan and it's housing. There are four screws with an alan wrench hole on them to remove the housing.  Once you have it removed, you can tell that the fan is held in place from the top, which makes sure that it will not move out of the way during operation, maintaining a very steady airflow. There are two different wires coming from the fan.  These two wires are the power wire, which is in the 4-pin PWM configuration.  There is also a fan controller that is attached directly to the fan. The fan is a Cooler Master A12025-20RB-4DP-F1 and colored black with red LEDs, which is a different choice than other heatsinks that are out there, not better, not worse.




When you remove the fan and the mounting hardware for it, you can see the overall heatsink design quite a bit better. There are two tall towers that are positioned upright with six of the eight heatpipes going directly to these towers. There are two more heatsink arrays that are set out behind the first two in a 90 degree angle, creating a netting look when viewed from the side. The two side heatsinks have two dedicated heatpipes delivering the heat from the processor.




Now that we know exactly what the heatsink looks like and it's overall design, it's time to take a look at what the specifications of this monster are!

To properly test the Cooler Master V8 CPU Cooler, I will be monitoring the highest temperature of the processor at Idle (little to no CPU usage), and at 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 30 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 processor's temperatures correctly. I will be taking the four highest temperatures that were produced during the test, and report 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 1.34v. 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.






After carefully testing the Cooler Master V8 CPU Cooler, you can see that it was able to keep about the same temperatures between the overclocked and the stock idle conditions, which let it tie the Thermalright Ultra 120 Extreme during the stock testing.  But, when it was overclocked, it was 2° lower than the Thermalright. Cooler Master has done something right with this cooler, as the temperatures were lower than the previous champion, only by 1°, during the overclocked full load testing, but it was 3° higher during the stock full load testing.



The Cooler Master V8 CPU Cooler, what is there to say about this mammoth of a cooler? Well for starters, I would like to recap the performance of this cooler, as it was able to keep a 1° difference between it's stock and overclocked idle temperatures, and gain only 18° on the full load temperatures between the stock and overclocked speeds. The Cooler Master V8 was also able to beat out every single CPU cooler (including the Thermalright Ultra 120 Extreme) that it was paired against.  It may not have been by a landslide, but a few degrees here, and a few degrees there is always a great thing for an overclocker/enthusiast to achieve, as it will allow us to get more out of our hardware. The sheer size of the V8 not only was a good thing as it was able to completely house a 120mm fan in the center of it, but it also was a slight downside, as the cooler almost did not fit inside of my Cooler Master Cosmos S, which seems to be quite deep and hold most coolers. I was not very pleased with the mounting hardware that came with the Cooler Master V8, it required me to remove the entire motherboard from the chassis to accommodates a new backing plate.  While most other coolers that are on the market share a very similar universal socket 775 mounting plate on the back, this did not. It was not all bad for the mounting hardware on the V8, I did like how sturdy the new mounting plate made the V8, and how well it seemed to hold it in place. The innovative design of the V8 is also a great positive for the cooler, it took a total of eight heatpipes to make the entire cooler work as needed, as well as took that many to keep it all held together. I was somewhat skeptical as to how well the cooler would hold up under a longer duration of time with the "mesh" look to the intake and exhaust sides of the cooler for air to flow, as it looked somewhat restrictive.  However, it was able to hold up just fine. The multi-platform design adds an extra value to the cooler, not only if you are looking for a cooler to cool your Socket 775 system, but if you ever decide to go with an AMD based socket AM2 or older system, you would still be able to use that cooler.

Overall, I was very impressed with this cooler, the design was magnificent and the performance was much better than I was expecting it to be. I would suggest that anyone who is looking for a new cooling solution to try this cooler out, or to anyone looking to begin down the overclocking road. This cooler should be able to not only keep your processor cool, but also make your case look great with it's red glow.
