DeepCool has released their new air cooler named AK620. This is a dual-tower configuration in 120mm size. The Assassin-III (dual 140mm) has been the high-end cooling solution in the category of air cooling so far from DeepCool. It would be interesting to see how much performance difference there would be between these two coolers. This cooler packs 6x copper heat pipes with a dense array of fins. The pipes are nickel-plated. We have a convex base on this cooler. The cooler is compatible with the Intel LGA1200/115x/20xx and AMD AM4/AM3+/AM3+AM2+/AM2/FM2+/FM2/FM1 sockets. While we properly elaborate on the DeepCool AK620 Review, let’s first check the specifications and comparison with other Coolers in this range.

DeepCool AK620 Packaging and Unboxing

The cooler is shipped inside a cardboard box that has a paperboard cover.

There is a picture of the cooler upfront with the model number. I like the minimalistic layout here.

The specifications are printed. The cooler comes with 2x 120mm fans rated for 68.99 CFM at 2.19 mmAq at 12VDC.

The assembled cooler is nicely packed between 2x Styrofoam pads. The mounting hardware is placed inside a cardboard box.

The Styrofoam pads have cutouts on the sides showing the metal fan clips. This would help in packing the cooler again correctly by aligning the clips with the cutouts.

Let’s take a look at what is provided in the box.

The accessories are placed inside a brown color box.

There is an elaborative user guide in the accessories to help the users during the installation.

There is a metallic Intel backplate with pre-installed standoffs. This would reduce the installation steps.

We have:

2x AMD Mounting Brackets
4x AMD Standoff screws

We have:

2x Intel Mounting Brackets
4x Thumb Nuts
4x Intel LGA20xx pillars
4x Intel other sockets pillars

We have:

1x Philips Screw Driver
1x PWM Y-splitter cable
1x Thermal Paste

Closer Look

Let’s take a look at the cooler.

The overall dimension of the assemble cooler is 129x138x160mm (LxWxH). The dimension of the heat sink only is 127x110x157mm (LxWxH). The net weight of the cooler is 1456 gm.

Both towers have plastic-made black ribbed design covers on the top. There is a teal color DeepCool logo on one corner. These covers are designed to sync well with the new PC cases from DeepCool and we can see where DeepCool is heading with their ecosystem in terms of aesthetics. These covers are removable as they sit on a clamp.

The above picture shows the top of the towers with the covers popped off. The good deal here is that the covers can be rotated and put back on. That way the user can configure the branding corner as per the layout requirement.

The above picture shows the underside of the top covers. It can be clearly seen that these are plastic made. The build quality is fine so there should not be an issue.

Notice the DeepCool logo placement? We rotated one cover to highlight the possibility. The height of the cooler is actually less than 160mm since the top covers and their housing takes up some spacing.

The left and right sides of the towers are identical in layout. The fins have a joint assembly here. The middle section has an inset and the sides have raised surfaces. This is where the heads of the fan clips are rested on. We have two thick towers.

The exterior sides of the towers feature asymmetrical layout on the fins. These are called matrix fins arrays. The fins are designed and stacked in a manner that 9 fins in any row have inset and protruded design alternatively. The protruded layout starts from both edges of the towers. The towers have stepped design towards the base as 5 fin plates are in recessed layout as compared to the rest of 45 fins. We have a total fin count of 50. The 5 fins on the base are in straight line.

The interior sides of the towers have a simple and plain layout with fins placed in a straight line. The interior portion of the towers poses less resistance to the airflow.

The above picture shows the displacement of the heat pipes inside the heatsink.

The DeepCool AK620 packs 6x copper heat pipes in 6mm thickness. These are nickel plated and jointed with the fins assembly. Seems like we don’t have a soldered assembly here. They are making an evenly spread-out contact with the fins.

There is a protective sticker pasted on the base. It shows a dimension of 52x42mm. Don’t confuse this with the actual dimension of the base. This dimension is for the sticker only.

The nickel coated copper base of the cooler has a dimension of 40x38mm. It is almost a mirror finish. The base is in a convex layout.

The mounting plate is pre-installed and has spring-loaded screws on both sides. The mounting plate is secured using a screw implying that it is removable.

DeepCool has provided 2x FK120 120mm fans with the AK620. These are non-RGB fans. The peculiar design element is all back color scheme and square frame of these fans. Each fan has 9x blades. The boundary of the frame has inlet stepped design. There is a DeepCool branding on the center.

There is a dotted arrow symbol showing the direction in which the blades would spin.

The other side of the frame has a dotted arrow symbol showing the direction of airflow through the fan.

The corners have full-height anti-vibration rubber mounts. Notice the symbols?

The fan is rated for 0.12A at 12VDC drawing 1.44W power. The fans are made in China. One of the 4x arms has a wider body with latches to catch the wires.

The fans have flat cables with 4-pin PWM connectors.

Here are the specifications of the fan:

Speed (RPM)	500 ~ 1850 ±10%
Airflow (CFM)	68.99
Air Pressure (mmAq)	2.19
Noise dB(A)	≤ 28
Connector	4-pin PWM
Bearing Type	Fluid Dynamic Bearing
Rated Voltage (V)	12

DeepCool AK620 Installation

I appreciate the DeepCool’s design team to reduce the installation steps and making the installation process convenient.

We have to deal with 11 components in total to mount the installation kit. Effective from this content, we will not be giving detailed installation steps as the user guide is there to cover it.

Clearance

The height of the cooler is 160mm. Keep this in mind while planning your build with respect to the PC Chassis as the chassis should have support for the CPU cooler’s height of a minimum of 161mm or so.

The heatsink has more clearance for the RAM height as can be seen in the picture. But this clearance gets limited with the front 120mm fan giving 47mm in total. But the height of the fan can be adjusted making more room for the RAM but increasing the overall height of the cooler.

The cooler does not block the first 16x PCIe slot on MSI MAG Z490 TOMAHAWK.

The cooler does not hinder the IO side of the motherboard.

The cooler has good enough clearance from the top of the motherboard since the width is 129mm.

DeepCool AK620 Testing & Benchmarks

Following configuration has been used: –

Intel i7 10700k
MSI MAG Z490 TOMAHAWK
T-Force NightHawk RGB 16GB @ 3200MHz
Nvidia GeForce GTX 1080 FE
addlink S70 256GB NVMe SSD
bequiet! Straight Power 11 850W Platinum PSU
Thermaltake Core P6 TG Snow Edition in open-frame layout

Here is the settings table for testing:

Clock (MHz)	3800 All Cores
Voltage (V)	1.030
Clock (MHz)	4700 All Cores
Voltage (V)	1.248
Clock (MHz)	5000 All Cores
Voltage (V)	1.320
Turbo Boost	Disabled
C-States	Disabled
Speed Step	Disabled
Thermal Paste	Noctua NT-H1
Thermal Paste Application	Dot Method in the center.
Test Run Time	30 minutes
Idling Time	10 minutes
Fan Speed	100% PWM Duty Cycle
Pump Speed [Where applicable]	Connected to the AIO Pump header to run at 100% speed
Header	CPU_Fan header for the fans and Pump_Header for the pump
Software	AIDA64 6.3 Extreme [FPU]

We are using Noctua NT-H1 thermal paste for cooler testing. Using the same thermal paste for all coolers would ensure standardization. Delta temperatures are reported on the graphs. The testing is done on an open air bench system. Once inside the chassis, the temperatures are expected to rise and would largely depend upon the optimal airflow inside the chassis.

Not every run of the stress test may yield the same result. This could well be due to many factors like mounting pressure, thermal paste application, varying ambient temperature. Not to mention the silicon differences even among the same category of the chips. Hence, it is pertinent to mention the testing methodology along with the specifics.

Let’s take a look at the results.

3.8GHz All Cores

4.7GHz All Cores

5.0GHz All Cores

The DeepCool AK620 has performed remarkably well.

Noise

We are not measuring the noise output due to construction work going around the place. Our subjective hearing tells us that this cooler is less noisy as compared to the AS500 Plus White.

Conclusion: Is DeepCool AK620 Worth Buying?

The AK620 is a new air cooler from DeepCool. In terms of the aesthetics alone, this cooler serves the DeepCool ecosystem quite well given the design layout of the heatsink and the top covers. This cooler is a dual-tower configuration but in 120mm size. Despite being a dual-tower design, it is a slim cooler. The dimension of the cooler is 129x138x160mm (LxWxH). The dimension of the heat sink only is 127x110x157mm (LxWxH). The net weight of the cooler is 1456 gm. The cooler is compatible with the Intel LGA1200/115x/20xx and AMD AM4/AM3+/AM3+AM2+/AM2/FM2+/FM2/FM1 sockets. It is mentioned that this cooler is compatible with the Intel LGA1700 socket but the user would need a mounting kit for that socket.

The heatsink comprises 50 nickel-plated aluminum fins. The fins have a matrix layout design on the exterior and a plain, straight line design on the interior of the towers. 5x fins are in a step design near the base. The cooler has a dense fin stack requiring high static pressure fans. The cooler has 6x nickel-plated copper heat pipes each having 6mm thickness. We have a nickel-plated convex copper base plate having a dimension of roughly 40x38mm which is enough to cover any chip on the supported sockets.

The top of the towers has elegant-looking covers with Teal color DeepCool branding on the corner. The design of these covers sits quite well with the matrix fin array design and the square frame black color fans. Together they give one heck of a good-looking cooling solution. Deepcool has included 2x FK120 fans having dimensions of 120x120x25mm. These fans are secured using metal fan clips. The maximum rated speed on these fans is up to 1850 RPM ±10% with a maximum airflow rating of 68.99 CFM and 2.19 mmAq air pressure rating. The sound level rating is up to ≤28 dBA and these fans are using Fluid Dynamic Bearings.

The overall build quality is top notch. Deepcool has provided easy-to-use mounting hardware for convenient installation of the cooler on any socket. The user manual is thorough. There is no RGB element on this cooler. It is best suited for neutral/stealth builds.

The AK620 has a height of 160mm making it compatible with most of the mid-tower chassis out there if not all. It has RAM clearance of up to 47mm with both fans. There is no RAM clearance with a single fan. The height of the fans is adjustable so the user can make more room for the taller RAM kits. Though this would increase the overall height of the cooler. There is no interference for the first x6 PCIe slot. Keep in mind that I am using the consumer platform as a reference.

We have tested the cooler on Intel i7 10700k against the might of Noctua NH-D15/S and DeepCool Assassin III coolers. The DeepCool AK620 has a powerful thermal performance with adequate noise output even at full speed. This cooler has more to it than meets the eye!
