DeepCool has, in recent times, delivered among the greatest CPU coolers in the marketplace, with choices just like the Murderer III and AK620. DeepCool’s present lineup contains each air and AIO coolers, in addition to laptop circumstances, keyboards, energy provides, and different equipment.
We most just lately reviewed DeepCool’s price range AG400 cooler, which carried out properly in our exams. In the present day we’re going to have a look at the AG400’s larger brother, the AG620. It will likely be the primary high-end air cooler we’ve examined with Intel’s i9-13900K. DeepCool markets the AG620 as a “a dual-tower 120mm CPU cooler that boasts spectacular 260W cooling energy efficiency that is been stripped down and optimized for terrific effectivity all through.”
Will DeepCool’s AG620 be sufficient of an improve to considerably enhance cooling efficiency on Intel’s i9-13900K? We’ll should put it via testing to search out out. However first, listed below are the AG620’s specs:

Included with the package deal are the next:
- Twin-tower heatsink
- 2x 120mm followers
- Mounts for Intel & AMD platforms
- Fan Splitter
- Thermal Paste
Set up
Putting in the AG620 was very straightforward. To start, you press the backplate to the motherboard,then safe it with the thumbscrew standoffs. As soon as completed, safe the mounting bars with the included screws. Apply the included thermal paste from the included packet to your CPU, then mount the CPU block and safe it with a screwdriver. The final step, in fact, is to connect the followers with the included clips.

Options of the DeepCool AG620
Matrix Fin Array
The AG620 incorporates a matrix fin array, resembling a checkerboard, which is designed to extend the static stress of the airflow and enhance total effectivity.
Convex Copper Base, bi-directional warmth pipe expertise
The AG620 encompasses a precision-machined convex copper base and 6 copper warmth pipes which have been optimized for peak thermal switch, no matter whether or not the cooler is put in in a vertical or horizontal case.
2x Excessive Effectivity Followers
There’s extra to a cooler than simply the heatsink and radiator. The bundled followers have a major influence on each cooling and noise ranges. Included are two 9-bladed 120mm followers which run as little as 300 rotations per minute (RPM) for full silence at idle hundreds.
| Dimensions | 120 x 120 x 25 mm |
| Fan Velocity | 300-1,850 RPM |
| Air Move | As much as 67.88 CFM |
| Air Stress | 2.04 mmAq |
| Lighting | None |
Testing Methodology
Whereas it was pretty straightforward with earlier generations of CPUs for coolers to maintain the flagship i9 processor properly underneath TJ max (the utmost temperature a CPU can maintain with out throttling) in robust workloads, that is not realistically potential with the Core i9-13900K with out excessive cooling (or enabling energy limits).
Once I started testing coolers on Intel’s Core i9-12900K, I discovered that some merchandise that cooled the i9-10900K properly struggled in some situations when paired with the Alder Lake CPU – and Raptor Lake is much more troublesome to chill in these conditions. Whereas previously a CPU hitting its peak temperature was trigger for concern, fans are going to should be taught to simply accept excessive temperatures as “regular” whereas operating demanding workloads with Raptor Lake and Ryzen 7000 CPUs.
Fashionable AMD and Intel CPUs are designed to run pretty sizzling with none issues – as much as 95 levels Celsius for AMD Ryzen 7000 CPUs, and as much as 100 C for Intel’s Core i9-13900K. Comparable habits has been customary in laptops for years as a consequence of cooling limitations.
Moreover, Intel’s i9-13900K helps Adaptive Increase Know-how (ABT), which permits the CPU to dynamically enhance to greater all-core frequencies primarily based on accessible thermal headroom and electrical situations. This permits multi-core hundreds to function at as much as 5.5 Ghz if the required quantity of thermal dissipation is there. This characteristic works in a means that actively seeks excessive temperatures: If the chip sees that it’s operating beneath the 100 levels C threshold, it’ll improve its efficiency and energy consumption till it reaches the secure 100 C restrict, thus sustaining greater clocks (and offering higher efficiency) for longer durations.
The elevated cooling challenges posed by Raptor Lake imply that we’ve needed to change among the methods we check coolers. Some coolers have been in a position to go Cinebench R23 multicore testing with Intel’s twelfth Gen i9-12900K when energy limits have been eliminated (though solely the strongest fashions have been in a position to go that check).
Because the Raptor Lake 13900K actively adjusts in a means that seeks its high secure temperature, we’ll evaluate efficiency as a substitute by complete benchmark scores and clock speeds maintained.
I’ll be testing Intel’s i9-13900K CPU utilizing Asus’ TUF Gaming Z690 Gaming Plus WIFI motherboard and Cooler Grasp’s HAF 700 Berserker PC case, with case followers restricted to 35% speeds. The motherboard’s default fan curve is used for the CPU Cooler’s followers.
Along with testing Cinebench with out energy limits enforced, we’ll even be displaying outcomes when the CPU’s energy consumption is restricted to a extra cheap 200W. We’ll additionally present outcomes at 125W for many who favor whisper-quiet cooling, at the price of some efficiency. For each of those outcomes, we’ll present conventional delta over ambient temperature outcomes.
We’ll additionally present noise degree measurements recorded utilizing a PSPL25 Sound Meter for all three energy ranges examined, to check how a lot noise every cooler makes in numerous situations. We anticipate most coolers to run successfully silently at 125W. You’ll discover that our noise degree graphs begin at 36 dBA – that’s as a result of 36dBA is the noise ground (the bottom studying we will measure) in our testing setting. Needless to say noise measurements are logarithmic, that means the variations between the noise ranges of the coolers might be larger than these graphs would recommend
LGA1700 Socket Bending
Observe there are a lot of elements aside from the CPU cooler that may affect your cooling efficiency, together with the case you employ and the followers put in in it. A system’s motherboard may also affect this, particularly if it suffers from bending, which leads to poor cooler contact with the CPU.
With a view to stop bending from impacting our cooling outcomes, we’ve put in Thermalright’s LGA 1700 contact body into our testing rig. In case your motherboard is affected by bending, your thermal outcomes might be worse than these proven under. Not all motherboards are affected equally by this difficulty. I examined Raptor Lake CPUs in two motherboards. And whereas one in all them confirmed important thermal enhancements after putting in Thermalright’s LGA1700 contact body, the opposite motherboard confirmed no distinction in temperatures in any respect! Try our overview of this contact body for extra info.
