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 instances, keyboards, energy provides, and different equipment.
We most just lately reviewed DeepCool’s finances AG400 cooler, which carried out nicely in our assessments. Right this moment we’re going to take a look at the AG400’s greater brother, the AG620. It is going to 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 must put it by means of testing to seek out out. However first, listed below are the AG620’s specs:

Included with the bundle 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, after all, 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 strain of the airflow and enhance total effectivity.
Convex Copper Base, bi-directional warmth pipe know-how
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 Pace | 300-1,850 RPM |
| Air Move | As much as 67.88 CFM |
| Air Strain | 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 nicely below TJ max (the utmost temperature a CPU can maintain with out throttling) in powerful workloads, that is now 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 nicely 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 must be taught to just accept excessive temperatures as “regular” whereas working demanding workloads with Raptor Lake and Ryzen 7000 CPUs.
Fashionable AMD and Intel CPUs are designed to run pretty scorching 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 commonplace in laptops for years resulting from cooling limitations.
Moreover, Intel’s i9-13900K helps Adaptive Increase Expertise (ABT), which permits the CPU to dynamically increase to greater all-core frequencies primarily based on accessible thermal headroom and electrical circumstances. 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 manner that actively seeks excessive temperatures: If the chip sees that it’s working beneath the 100 levels C threshold, it’s going to 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 take a look at coolers. Some coolers had been in a position to go Cinebench R23 multicore testing with Intel’s twelfth Gen i9-12900K when energy limits had been eliminated (though solely the strongest fashions had been in a position to go that take a look at).
For the reason that Raptor Lake 13900K actively adjusts in a manner that seeks its prime secure temperature, we’ll examine efficiency as an alternative 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 choose 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 match 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 flooring (the bottom studying we are able to measure) in our testing surroundings. Take into account that noise measurements are logarithmic, which means the variations between the noise ranges of the coolers will probably be greater than these graphs would recommend
LGA1700 Socket Bending
Notice there are lots of elements apart from the CPU cooler that may affect your cooling efficiency, together with the case you utilize and the followers put in in it. A system’s motherboard also can affect this, particularly if it suffers from bending, which leads to poor cooler contact with the CPU.
So as to forestall 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 will probably be worse than these proven under. Not all motherboards are affected equally by this challenge. I examined Raptor Lake CPUs in two motherboards. And whereas certainly one of them confirmed vital thermal enhancements after putting in Thermalright’s LGA1700 contact body, the opposite motherboard confirmed no distinction in temperatures by any means! Take a look at our evaluation of this contact body for extra data.
