Cooler Master V6 GT CPU Cooler


Product(s): Cooler Master V6 GT CPU Cooler
Provided By: Cooler Master



Today we've got a new cooler from Cooler Master on the test bench here at BCCHardware, the new V6 GT CPU Cooler.

This cooler has an "automotive" design and features a "oil cap" button on the top to control the built in customizable LED lights on the top of the cooler. Overall this cooler has a bit more of an aggressive look yet isn't over the top like some others.

The V6 GT cooler features 2 120mm fans (one on each side) so performance should be decent thanks to the more than adequate amount of airflow.

Let's see what the Cooler Master V6 GT is all about in the next section.

Much like the V8 and V10 coolers the V6 GT has a "automobile/engine" design to it. The big button on the top of the V6 GT lets you turn on the built in LED on the top as well as toggle between 3 different colors (purple, red and blue).

The V6 GT features 2 120mm fans that can run anywhere from 800-2200 RPM and are controlled by PWM. Alternatively you could plug the fans into a fan controller if you prefer to control these fans manually.

The V6 GT is a "heatpipe tower" cooler (which is a very popular design). This cooler has aluminum fins and a copper base and features 6 heatpipes (as you can see in the pictures below).

As you can see in the next set of pictures (right) both of the 20mm fans are removable (and you will have to remove them to install this cooler).

Both of the 120mm fans snap off easily and don't require any tools to get them on or off.

With the V6 GT you get everything you need to install this cooler on pretty much any CPU currently available (including the new 1155 Sandy Bridge CPU from Intel). Cooler Master has also included a Y-Adapter so you can plug both fans into one fan header if you wish.

That's pretty much everything when it comes to the Cooler Master V6 GT. In the next section we'll install this cooler and see how it stacks up against other coolers.




Cooler Master V6 GT CPU Cooler Specifications:


All specifications taken from

V6GT follows in the footsteps of the revolutionary V8 and V10 CPU coolers from Cooler Master.  Designed with a muscular engine look, the V6GT fits nicely with any performance hardware.  The V6GT also features new mechanical structure that includes:  V-shaped heatpipe array, asymmetrical aluminum fins (which are densely stacked for optimal cooling), two 120mm silent fans with PWM speed control function and DynaLoop™ long life technology, snap-on cover to conveniently replace fan if needed.



  • Densely stacked asymmetrical tilted aluminum fins for muscle cooling performance.
  • "Double-V" heatpipe array helps spread out the six heatpipes to fully utilize the cooling fins on the cooler. It also allows airflow to reach each individual heatpipe as opposed to traditional coolers.
  • Accelerating twin high-speed PWM fans with tool-free fan boxes deliver invincible cooling capability.
  • Engine oil cap controls the LED strip with color changing function.
  • DynaLoop™ Bearing Fan: Innovated self-lubricating bearing mechanism decreases oil-loss commonly seen on sleeve bearing fans. Evolutionary wave blade fan provides tremendous airflow with steady pressure.
  • Snap-on cover to conveniently add a second fan if needed.

Testing and Installation:

The V6 GT cooler features a built in LED light on the top of the cooler that can be changed to 3 different colors (or turned off all together). You can pick between Purple, Red, or Blue (all pictured below).

Installation of the V6 GT is going to require you to install a back plate and will require you to remove the motherboard. You will also have to remove both fans from the V6 GT to get the cooler attached to the mounting brackets. Once you have the fans removed the cooler installs pretty easily and I didn't encounter any issues with the installation of this cooler.

There we go, we've got the V6 GT all installed and ready for our testing which you can read all about in the next section.





Test Setup:

For Intel (LGA1336) testing we will be using the Intel Core i7 920 CPU, which produces 130 Watts of heat. This could be considered a mid-range processor, and while most Dual-Core processors produce ~50-80 Watts of heat, this should give you a pretty accurate estimate of what type of temperatures a cooler will provide you with.

For both AMD and Intel testing, we have taken all temperatures using CoreTemp v.0.99.4. CoreTemp takes a temperature from the CPU core, and allows for much more uniform results across different motherboard and CPU platforms. These temperatures may seem higher than other temperature recordings; because chances are they are taking temperature recordings using the diode underneath the CPU, which isn't able to be as accurate, and can really fluctuate between different brands of motherboards.

For all tests we are using the Highspeed PC Top Deck Tech Station , and we are using no additional cooling in our testing. All temperatures are recorded in a controlled environment that is set to 23 degrees Celsius (73.4 Fahrenheit) to provide fair results between coolers.

For all tests we use Arctic Cooling MX-2 High-Performance Thermal Compound (Paste), We use the same thermal paste in all our testing so that we can keep our results consistent. If a cooler is shipped with thermal paste pre-applied, it will be removed and we will re-apply it with Arctic Cooling MX-2 to provide fair results.


Intel Test System:


For our testing of the V6 GT we have tested this cooler at both Maximum and Minimum speeds (800 RPM and 2200 RPM). This cooler features PWM which will automatically adjust fan speed based on CPU temperatures, however, for our testing we have set the fan speed to a set speed to show what this cooler is capable and to easily compare it with other coolers on the market.

At low speeds the V6 GT is nice and quiet and still offers almost a 10 degree reduction over stock cooling. In our testing we've used one of the hottest CPU's available so for most "lower wattage" CPU's chances are good this cooler would probably not have to run much over 700 RPM to keep up (even with a 140 watt CPU it was able to easily keep up with our CPU).

At full speed the performance of the V6 GT is pretty impressive and is able to keep up with most of the other coolers we've tested. Unfortunately at full speeds there is a fair amount of noise so if you want max performance you will have to deal with the noise. The V6 GT is a PWM controlled cooler so the majority of the time you'll never even get close to max speed so noise probably won't be an issue for most users.

As you can see in the last chart when compared to the other coolers we've tested the V6 GT was able to keep up with the best when running at full speeds. When running at full speeds this cooler is a bit nosier than others we've tested so if you are the type of user who wants maximum performance you might be a bit annoyed at the noise.

Overall I'd say the performance of the V6 GT is good and even when running at the lowest fan speeds possible we were able to easily keep up with our hot Intel i7 CPU without any issues.




Cooler Master V6 GT CPU Cooler Final Thoughts:

The new V6 GT CPU cooler from Cooler Master is the first cooler we've had on our Intel i7 test system from Cooler Master and overall it scored very well in our testing. The V6 GT is following in the footsteps of other Cooler Master coolers such as the V8 and V10 CPU coolers that feature a "automotive" or "engine" design. The design of the V6 GT is nice and sleek but not over the top like some other coolers. The LED light on the top is customizable and you can choose from either Red, Blue or Purple lighting (or turn the LED lights off completely).


The build quality of the V6 GT is very good and exactly what I expected from Cooler Master. Cooler Master is known for producing high quality products and the V6 GT is no different.

Overall we were happy with the performance of the V6 GT in our testing. At full fan speeds the V6 GT puts up some pretty decent performance numbers, but running the fans at full speed does produce a fair amount of noise and chances are good you probably won't want to leave the fans running at full speed. Even at low speeds the V6 GT was easily able to keep up with our 140 Watt CPU and still offer a decent improvement in cooling over a stock cooling solution.

At the end of the day the Cooler Master V6 GT is a good choice if you are looking for a CPU cooler that looks good and performs just as well. While the V6 GT fell just short of our Gold award it was still worthy of our "Editor's Choice - Silver" award and is a good value for a good cooler.



  • Good Performance
  • High Quality Construction
  • Sleek Design



  • Fans loud at high speeds
