DeepCool has, in recent times, delivered a number of the greatest CPU coolers in the marketplace, with choices just like the Murderer III and AK620. DeepCool’s present lineup consists of 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 exams. As we speak 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 testing to seek out out. However first, listed below are the AG620’s specs:

Packing and Included Contents
DeepCool’s AG620 is available in a considerably small field, with molded foam and cardboard used for defense of the inside contents.

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 simple. 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 general 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 big impression 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 masses.
| Dimensions | 120 x 120 x 25 mm |
| Fan Pace | 300-1,850 RPM |
| Air Stream | As much as 67.88 CFM |
| Air Stress | 2.04 mmAq |
| Lighting | None |
Testing Methodology
Whereas it was pretty simple 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 robust workloads, that is now not realistically potential with the Core i9-13900K with out excessive cooling (or enabling energy limits).
After 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 tough 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 simply accept excessive temperatures as “regular” whereas working demanding workloads with Raptor Lake and Ryzen 7000 CPUs.
Trendy 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 conduct has been normal in laptops for years resulting from cooling limitations.
Moreover, Intel’s i9-13900K helps Adaptive Increase Expertise (ABT), which permits the CPU to dynamically enhance to greater all-core frequencies based mostly on out there thermal headroom and electrical circumstances. This enables multi-core masses to function at as much as 5.5 Ghz if the required quantity of thermal dissipation is there. This characteristic works in a approach that actively seeks excessive temperatures: If the chip sees that it’s working beneath the 100 levels C threshold, it can enhance 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 a number of the methods we take a look at coolers. Some coolers had been in a position to cross 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 cross that take a look at).
Because the Raptor Lake 13900K actively adjusts in a approach that seeks its high secure temperature, we’ll examine efficiency as an alternative by taking a look at 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 affordable 200W. We’ll additionally present outcomes at 125W for individuals 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 stage 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 count on most coolers to run successfully silently at 125W. You’ll discover that our noise stage 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 atmosphere. Remember that noise measurements are logarithmic, which means the variations between the noise ranges of the coolers can be greater than these graphs would recommend
LGA1700 Socket Bending
Observe there are numerous components 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 affect this, particularly if it suffers from bending, which leads to poor cooler contact with the CPU.
With the intention 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 can be worse than these proven beneath. Not all motherboards are affected equally by this challenge. I examined Raptor Lake CPUs in two motherboards. And whereas considered one of them confirmed important thermal enhancements after putting in Thermalright’s LGA1700 contact body, the opposite motherboard confirmed no distinction in temperatures in any way! Try our evaluate of this contact body for extra info.
