In recent years, DeepCool has best cpu cooler On the market, you have the following options Assassin III When AK620DeepCool’s current lineup includes both air coolers and AIO coolers, as well as computer cases, keyboards, power supplies, and other accessories.
I recently reviewed DeepCool budget AG400 cooler, which worked well in our tests. Today we are going to take a look at his AG620, the big brother of the AG400. This will be the first high-end air cooler we’ve tested with Intel’s i9-13900K. DeepCool markets the AG620 as “a stripped-down and optimized dual-tower 120mm CPU cooler with an impressive 260W of cooling power performance for great overall efficiency.”
Is DeepCool’s AG620 a good enough upgrade to significantly improve the cooling performance of Intel’s i9-13900K? We’ll have to do some testing to find out. First, here are the specs for the AG620:

Packing and inclusions
DeepCool’s AG620 comes in a rather small box with molded foam and cardboard to protect the contents.

Package includes:
- dual tower heatsink
- 2x 120mm fan
- Mounts for Intel & AMD Platforms
- fan splitter
- thermal paste
install
Installing the AG620 was very easy. First, press the backplate onto the motherboard, then secure it with the thumbscrew standoffs. Once installed, secure the mounting bar with the included screws. Apply the included thermal paste from the included package to the CPU, install the CPU block and secure it with a screwdriver. The final step, of course, is to attach the fan with the included clips.

Features of DeepCool AG620
matrix fin array
The AG620 incorporates a checkerboard-like matrix fin array designed to increase airflow static pressure and improve overall efficiency.
Convex copper base, two-way heat pipe technology
The AG620 features a precision machined convex copper base and six copper heat pipes optimized for peak heat transfer whether the cooler is mounted in a vertical or horizontal case is characterized by
2x high efficiency fans
Coolers are more than just heatsinks and radiators. Bundled fans have a big impact on both cooling and noise levels. Two HE include 9-blade HE 120mm fans that run at 300 revolutions per minute (RPM) and are completely silent under idle load.
| Size | 120×120×25mm |
| fan rotation speed | 300 to 1,850 RPM |
| air flow | Up to 67.88 CFM |
| air pressure | 2.04mmAq |
| lighting | none |
test method
With previous generation CPUs for coolers, it was fairly easy to keep the flagship i9 processor well below TJ max (the maximum temperature the CPU can sustain without throttling) under demanding workloads, but with the Core i9-13900K This is no longer realistically possible. Extreme cooling (or enabling power capping).
When we started testing the cooler with Intel’s Core i9-12900K, we found that some that cooled the i9-10900K well enough struggled in some scenarios when paired with Alder Lake CPUs. Raptor Lake is even more difficult to cool in these conditions. Peak CPU temperatures have been a source of concern in the past, but enthusiasts should learn to accept high temperatures as ‘normal’ while running demanding workloads on Raptor Lake and Ryzen 7000 CPUs. there is.
The latest AMD and Intel CPUs are designed to run fairly hot without problems, up to 95 degrees Celsius for AMD Ryzen 7000 CPUs and up to 100 degrees Celsius for Intel’s Core i9-13900K. Similar behavior has been standard in laptops for years due to cooling limitations.
Additionally, Intel’s i9-13900K supports Adaptive Boost Technology (ABT), allowing the CPU to dynamically boost to higher all-core frequencies based on available thermal headroom and electrical conditions. . This allows multi-core loads to run up to 5.5 GHz with the required amount of heat dissipation. This feature works in an aggressive hot-seeking manner. If the chip detects that it is operating below the 100°C threshold, it will increase performance and power consumption until it hits the safe 100°C limit, maintaining higher clocks (and providing better performance). increase).
The increased cooling challenges with Raptor Lake meant that we had to change some of the ways we test coolers. Some coolers were able to pass the Cinebench R23 multi-core test with Intel’s 12th Gen i9-12900K when the power cap was lifted (although only the most powerful models were able to pass that test ).
Since the Raptor Lake 13900K aggressively tunes in a way that seeks the best safe temperature, we instead look at total benchmark scores and sustained clock speeds to compare performance.
Asus’ TUF Gaming Z690 Gaming Plus WIFI motherboard is used to test Intel’s i9-13900K CPU. Cooler Master’s HAF 700 Berserker PC case, case fans are limited to 35% speed. The motherboard’s default fan curve is used for the CPU cooler fan.
In addition to testing Cinebench with no power cap applied, we also show the results of limiting the CPU power consumption to a more reasonable 200W. We also show the results at 125W for those who prefer very quiet cooling at the expense of some performance. For both of these results, we show the traditional delta result versus ambient temperature.
We also provide sound level measurements recorded using a PSPL25 sound meter for all three power levels tested, comparing the noise produced by each cooler in different scenarios. We expect most coolers to run effectively and quietly at 125W. You will notice that the noise level graph starts at 36 dBA. This is because 36 dBA is the noise floor (minimum measurable value) in our test environment. Note that noise measurements are logarithmic. In other words, the difference in cooler noise levels is greater than these graphs suggest.
LGA1700 socket bend
Keep in mind that besides the CPU cooler, there are many other factors that affect cooling performance, such as the case you use and the fans attached to the case. Your system’s motherboard can also affect this. suffer from bendingThe result is poor cooler contact with the CPU.
To prevent bending from affecting cooling results, Thermalright LGA 1700 contact frame to our test equipment. If the motherboard is subject to bending, the thermal results will be worse than those shown below. Not all motherboards are affected by this issue. We tested the Raptor Lake CPUs on two motherboards.One of them showed significant thermal improvement after installing Thermalright’s LGA1700 contact frame, while the other motherboard had no difference in temperature at all!
