DeepCool was based in Beijing in 1996. And the corporate has, in recent times, delivered among the finest 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 not too long ago reviewed DeepCool’s AK500 cooler, which carried out effectively in our checks. At the moment we’re going to take a look at a extra budget-oriented product, the single-tower AG400. With the newest CPUs from AMD and Intel requiring ever extra succesful cooling, is a single tower cooler sufficient to tame Intel’s 13900K? We’ll should put it by testing to search out out. However first, listed below are the AG400’s specs from DeepCool.

- Single-tower heatsink
- 120mm fan
- Fan clips for the included fan
- Mounts for all fashionable CPU sockets (together with AM5 & LGA1700)
- A single-use packet of thermal paste
- Handbook
Options of the AXP120-X67
Single Tower Heatsink with Matrix Fin Array
The AG400 (just like the bigger AK500) incorporates a matrix fin array resembling a checkerboard, which is designed to extend the static stress of the airflow and subsequently higher dissipate warmth. It additionally options 4 6mm direct-contact copper heatpipes. When putting in the AG400, the pre-installed fan doesn’t must be disassembled through the course of, simplifying the set up course of and saving time.

Full RAM Clearance
Some coolers with lower-mounted cooling fins received’t match you probably have full-height RAM put in (RGB RAM tends to be taller), however with DeepCool’s AG400 that’s not a difficulty – it has full RAM peak compatibility.

Customized 120mm fan
There’s extra to an air cooler than simply the heatsink. The bundled fan(s) have a major affect on cooling and noise ranges. Included with the AG400 is an unnamed customized 120mm fan that you simply received’t discover on retail cabinets – it’s solely out there with choose DeepCool CPU coolers.
| Mannequin | Customized 120mm fan |
| Dimensions | 120 x 120 x 15 mm |
| Fan Pace | As much as 2000 RPM ±10% |
| Air Move | As much as 75.89 CFM |
| Air Stress | As much as 2.53mm H20 |
| Noise Degree | As much as 31.6 dB(A) |
| Bearing Kind | Hydro Bearing |
| Lighting | ARGB |
Testing Methodology
Whereas it was pretty simple with earlier generations of CPUs for coolers to maintain the flagship i9 processor effectively below TJ max (the utmost temperature a CPU can maintain with out throttling) in powerful workloads, that is not realistically potential on present technology CPUs (the 13900K particularly) 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 effectively struggled in some eventualities when paired with the Alder Lake CPU – and Raptor Lake is much more tough to chill in these conditions. Whereas up to now 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 working demanding workloads with Raptor Lake and Ryzen 7000 CPUs.
Trendy AMD & Intel CPUs are designed to run pretty scorching with none issues– as much as 95 levels C for AMD Ryzen 7000 CPUs, and as much as 100 levels C for Intel’s Core i9-13900K. Comparable habits has been commonplace in laptops for years on account of cooling limitations.
Moreover, Intel’s i9-13900K helps Adaptive Increase Expertise (ABT) which permits Core i9 processors to dynamically increase to increased all-core frequencies based mostly on out there thermal headroom and electrical circumstances. This permits multi-core masses to function at as much as 5.5ghz if the mandatory quantity of thermal dissipation is there. This function works in a method that actively seeks excessive temperatures: If the chip sees that it’s working beneath the 100-degree C threshold, it is going to improve its efficiency and energy consumption till it reaches the protected 100C restrict, thus sustaining increased 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 had been capable of 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 capable of go that check). Most liquid coolers and all air coolers I’ve examined “failed” that check as a result of the CPU reached TJ max on this situation.
With Raptor Lake’s 13900K, not a single cooler examined has been capable of preserve the CPU below TJ max on this check – as a result of as we identified, the chip is designed to dial up efficiency and energy till it richest that thermal end result. We’ll evaluate efficiency as a substitute by whole 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 laptop 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 individuals who desire 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 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 several eventualities. We count on most coolers to run successfully silently at 125W.
LGA1700 Socket Bending
Please be aware there are various 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.
As a way 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 will likely be worse than these proven beneath. Not all motherboards are affected equally by this concern. I examined Raptor Lake CPUs in two motherboards. And whereas one among them confirmed vital thermal enhancements after putting in Thermalright’s LGA1700 contact body, the opposite motherboard confirmed no distinction in temperatures in any respect! Try our assessment of this contact body for extra data.
