DeepCool was founded in 1996 in Beijing. 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.
recently reviewed DeepCool AK500 Cooler, which worked well in our tests. Today we will be looking at a more budget-friendly product, the single-tower AG400. The latest CPUs from AMD and Intel demand better cooling than ever before, but will a single tower cooler be enough to keep Intel’s 13900K at bay? You need to do. But first, here are the specs for the AG400 from DeepCool.

Features of AXP120-X67
Single tower heatsink with matrix fin array
The AG400 (similar to the larger AK500) incorporates a checkerboard-like matrix fin array. It is designed to increase the static pressure of the airflow to better dissipate heat. It also features four he 6mm direct contact copper heat pipes. When installing the AG400, the pre-installed fans do not need to be disassembled during the process, simplifying the installation process and saving time.

Full RAM clearance
Some coolers with bottom-mounted cooling fins won’t fit if full-height RAM is installed (RGB RAM tends to be taller), but DeepCool’s AG400 is fine. Full height compatibility of RAM.

custom 120mm fan
Air coolers are more than just heat sinks. Bundled fans have a big impact on cooling and noise levels. The AG400 includes an unnamed custom 120mm fan, not found on retail shelves. Only available on select DeepCool CPU coolers.
| model | custom 120mm fan |
| size | 120×120×15mm |
| fan rotation speed | Up to 2000 RPM ±10% |
| air flow | Up to 75.89 CFM |
| air pressure | Max 2.53mm H20 |
| noise level | Max 31.6dB(A) |
| Bearing type | hydro bearing |
| lighting | ARGB |
test method
With previous generation CPUs for coolers, it was fairly easy to keep flagship i9 processors well below TJ max (the maximum temperature a CPU can sustain without throttling) under demanding workloads, but current generation CPUs ( 13900K especially) without extreme cooling (or with power limiting enabled).
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 95C for AMD Ryzen 7000 CPUs and up to 100C 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), which allows Core i9 processors to dynamically boost to higher all-core frequencies based on available thermal headroom and electrical conditions. increase. 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 ).with most liquid coolers all The air cooler I tested “failed” that test because the CPU hit TJ max in this scenario.
On Raptor Lake’s 13900K, not a single cooler has been able to keep the CPU below its max TJ in this test. 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 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 provide sound level measurements recorded using a PSPL25 sound meter for all three power levels tested to compare the noise produced by each cooler in different scenarios. We expect most coolers to run effectively and quietly at 125W.
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. Especially if the motherboard is bent, the cooler will have poor contact with the CPU.
To prevent bending from affecting the cooling results, Thermalright’s LGA 1700 contact frame was attached to the test rig. 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 a significant thermal improvement after installing his Thermalright’s LGA1700 contact frame, while the other motherboard had no difference in temperature at all!For more information see this contact frame review please look at.
