Introduction
The importance of a Heatsink any computer is that it not only makes the computer more expandable in terms of performance but also makes the life of the computer component go up by as long as 20%. By this we all know how important a Heatsink, especially for gamers and computer enthusiasts who push their RIG to the limits.
Today we review yet another offering by Cooler Master, another tower based Heatsink which is set to compete with most of the products in market. However let’s see how far this product goes when it comes to serving the need of a Gamer & an enthusiast.
[BREAK=The Box]
The BOX
A first look at the front of the package, we see that Cooler Master has made sure that the logos define the compatibility of the product hence when picking the product from shelf; one does not have to really look into the product manuals for product compatibility. We do see that the PWM fans included with the Heatsink are illuminated with Blue LEDs. One logo that is missing here is the Core i7 compatibility of the product, rest everything is in place as always.
The back of the box pictures the dimensions of the Heatsink and does highlight the features of the product.
Either side of the box states the overall specification of the product and general information. Again the thing that is missing here is the compatibility of the product with the Core i7 range of CPUs.
Let’s see what comes with the box, next.

The Content
When opened, the box contains the N620 CPU cooler with pre installed 120mm PWM fans and below it is a chamber holding the accessories bundled with the product. It is a simple Pull Out approach for getting to the right stuff.
The accessories which are included in the bundle are
• Intel Socket (LGA1366 / LGA775) Mounting Kit.
• Socket (LGA 771 Skull trail only) Mounting Kit.
• AMD Socket (AM3 / AM2+ / AM2 / 940 / 939 / 754) Mounting Kit.
• All required screws.
• Cooler Mater thermal Paste.
• Installation Guide.
Now let’s take a closer look at the N620
[BREAK=The N620]
The N620
At first look the Cooler Mater N620 Looks like a beautifully crafted work of art where in cooler master has designed the Heatsink fins in such a manner that they support the 120mm fan installation at the same time solve the purpose of transferring the heat.
The best part of this design is that the fans are not located at the exact opposite side of the Heatsink, however are aligned in such a manner that the airflow is at an angular direction, which increases the surface contact of air and hence does maximum heat transfer.
Taking a closer look, we see that the Heatsink design from the top forms the letter ‘N’, which explains the name of the Heatsink being N620.
At the bottom of the two 120mm fans we see the rubber installation rather than the screw in approach, which minimizes the vibration caused at high speed and gives the fan a much stable installation.
Looking at the base of the Heatsink, we see the usual sticker and see the 5 heat pipe approach, the best part is that the 5th heat pipe in installation in 2 pieces on either side of the base, this gives the base a much needed space for installation in i7 processors plus it allows the heat to spread on a larger base for better cooling. Another advantage of this is all the heat pipes used in this Heatsink are now of different length, which always gives better heat transfer. All Copper base adds in to the cooling efficiency of the Heatsink.
In this picture we can clearly see the groves made in Cooling Fins for the installation of rubber damping & mounting system for 120mm Fans.
Now let’s move on and see the Dissected N620 and compare it with other Tower Coolers available in the market.
[BREAK=The N620 Inside Out]
The N620 Inside Out
When the fans removed, the N620 is of the same form factor as that of a Thermalright 120 and the letter ‘N’ influence on the design of the Heatsink is more prominent.
We can see 2 of the smallest heat pipes getting terminated at the farther end of the Heatsink plus 4 of the heat pipes being installed towards the centre of the fins of the Heatsink.
The surface finish of the heatsink’s base is flawlessly flat.
One of the best part of the Heatsink is the pair of PWM fans included in the bundle. The best this about the PWM fan is that you can control the RPM of the fan from the operating system itself, hence can tune it to much low noise and less RPM for regular needs and the MAX RPM setting for the gaming/over clocking need of a CPU. This pair of PRM Fan, if bought separately will cost not less than Rs. 1200.
Time for comparison, see how the N620 looks then compared to other heatsink’s in the market.
Let us take a look at the features of this Product.
[BREAK=Features & Specification]
Features & Specification
The main features of N620 are:
Universal Design
• Intel (LGA 1366 / LGA 775)
• AMD (AM2+ / AM2 / 940 / 939 / 754)
Optimum Air Flow
• Distinct appearance with dual fan bracket
• Unique dual fan cooling design ensures cool air accelerates straight through the Heatsink
Superior Cooling Performance
• Mirror finished copper base guarantees perfect contact between CPU and cooler
• 6 heat pipes optimize heat transfer
Product specification Sheet
The best part of the Heatsink is the hassle free installation which is done at the back of the motherboard; hence you don’t need to worry about not reaching those installation screws due to the large Heatsink on the motherboard.
Now let’s move on to the testing phase.
[BREAK=Test Configuration]
Test Configuration
For the purpose of testing this Heatsink, we made it sure that we test it against the best Air Cooling solution available in the market & hence we decided to benchmark it against TRUE & SCCF. Here is what the configuration looks like.
Open Case Test Setup
The Test Results
Here we see that the N620 does fall near the expected temperature and can compete with any of the tower cooling solutions available in the market. To note here is that TRUE & SCCF are used with Cooler Master 90CFM 19dBA Blue LED Fans.
Note : The N620, when tested was running at Minimum RPM (700rpm) and the fan used with TRUE & SCCF were running at Maximum RPM. When we did a full throttle to the N620 PWM Fans it did overpowered SCCF with Load temperature at 49 Degree Celsius & OC temperature at 55 degree Celsius going and was able to go neck to neck with TRUE.
And now the final thoughts.
[BREAK=The Conclusion]
The Conclusion
Scoping the N620 has been an existing experience, now much a Heatsink in the market come with a Push-Pull Heatsink fan installation however Cooler Master has delivered another state of the art product and have really proved that they can deliver quality product in this much price competing world of CPU Tower Coolers. The bundle of a pair of PWM Fan is a great add-on to this Heatsink, as you now don’t need to run around to get a better performing fan for this Heatsink.
The Pros
• Sturdy mounting bracket that is easy to install
• Back of the motherboard installation, easiest installation.
• Extremely quiet
• Unique Push Pull fan installation
• Bundled with PWM Fans
• Good cooling performance
• Universal Compatibility
• A sure bang for the buck
The Cons
• A bit pricy then the SCCF.
• Motherboard need to be removed for the case Heatsink installation (If the Case does not have Heatsink Installation Hole).
Being an author of this review I rate this product 4/5.
