Designed with precision, the high-performance DeepCool fan maximizes airflow and static pressure while keeping noise low due to a dynamic PWM range of 500 – 1850RPM. The FDB We’re looking at a new innovative lineup of DIGITAL air coolers from DeepCool which have a unique LCD display that allows for easy monitoring of your computer processor’s temperature and utilization statistics. These coolers are the first air coolers of their kind on the market, and as such have no competition from other cooling manufacturers. DeepCool launches this lineup with three models – the AK620, AK500, and AK400 Digital coolers.
allows compatibility with some ITX cases and with the top cover removed the cooler stands at a height of 153mm. Due to the compact design of the AK400, the installation of RAM Running Cinebench without power limits enforced is difficult to cool, and most coolers are unable to keep the CPU under it’s peak temperature in this scenario – so we’ll be looking at the maximum watts dissipated by the cooler in this situation. We founded Deepcool with the mission of providing the best and personalized thermal solutions for customers around the world. Deepcool was first established 1996 with its headquarters in Beijing and factory facilities in Shen Zhen that produced coolers and cooling accessories for desktops and servers. In response to rapid advancements in the PC sector Deepcool further expanded into AIO liquid cooling products, chassis, and power supplies. The most complete cooling comparison results will from the Ryzen 7700X section, which features results from 20 different coolers. I haven’t been testing the 13700K long, as such today’s review will only feature results from 12 coolers in total. Between the results shown on both CPUs, this should be a sufficient amount of data to show you how DeepCool’s AK400 Digital holds up with modern CPUs. This review will focus on the entry level cooler of the lineup – DeepCool’s AK400 Digital. Can this small cooler handle the heat of Intel’s i7-13700K and AMD’s Ryzen 7 7700X? I’ll show you how well it performs in the benchmarks, but first lets take a look at the installation and specifications of this cooler. Foreword & Testing Platform Configuration

All of the coolers tested achieved good acoustic levels here, including DeepCool’s AK400 Digital which ran at a very low noise level with 38.9 dBA measured during testing. AMD Ryzen 7 7700X Thermal and Acoustic Results Maximum Cooling Performance
Attach the fans using the included clips and connect them to your motherboard’s PWM connection. Finally, connect the USB header to your motherboard to be sure the display is powered. Intel i7-13700K Thermal and Acoustic Results Maximum Cooling Performance Running Cinebench without power limits enforced is difficult to cool, and most coolers are unable to keep the CPU under it’s peak temperature in this scenario – so we’ll be looking at the maximum watts dissapated by the cooler in this situation. While maximum performance testing is nice, a lot of folks prefer to test coolers with noise levels equalized. This can result in some performance loss in the most power intensive workloads like rendering. When noise normalized to 38.2 dBA, DeepCool’s AK400 Digital loses about 10% of it’s potential cooling performance dropping to 203W. This isn’t quite as impressive as the maximum cooling performance, but it’s still quite a good showing – comparable to good mid-range coolers like Cooler Master’s Hyper 622 Halo and Jiushark’s JF200 air coolers. 175W Thermal & Acoustic ResultsDeepCool was founded in 1996 in Beijing, China and is a favorite of many enthusiasts. They are well known for their air and water coolers and computer cases. They also offer fans, power supplies, and peripherals such as keyboards and mice. With a temperature of 43C over ambient, the AK400’s thermal performance is on the lower end of results we’ve seen from mainstream air coolers – but in this scenario temperature really isn’t a concern. What is a concern is noise levels, and with a measurement of 39.6 dBA it does well here. Conclusion Deepcool has been qualified to the ISO 9000 Quality Management System specifications. We implement strict quality controls through IQC, FAI, IPQC, and OQC systems to build a solid reputation of excellent quality. With a 50,000-hour rated operational lifespan for the FDB fan, DeepCool looks to be middling for a budget cooler in that number. Most loads that common users run won’t use more than 200W, so this is a better analogue for a worst case scenario of what folks might actually see in day to day usage.
Today we will be covering the recently released DeepCool AK400 CPU Cooler. There is still a market for slim, single tower coolers believe it or not. For one they are usually very cheap and easy to install. Now the question is, will this keep my CPU temps under control? We will answer that later in this review. But for now, let’s focus on the AK400 and what it offers. I don’t doubt this cooler will be able to handle any CPU under everyday use. It has 4 heat pipes and exposed copper on the heatsink. I also know from a previous review of the AK620 that the fan and cooler design work very well. This type of cooler is perfect for budget builds and when you are short on real estate. Let’s continue through this review and see everything this AK400 is all about! At 53C over ambient, The AK400 Digital is on par with the best results I’ve recorded from other air coolers and achieves this with low noise levels of 40.9 dBA – quieter than most of the other results shown here. DeepCool deploys its 120mm Fluid Dynamic Bearing fan for use on the AK400. The speed range on the 4-pin PWM control curve is 500-1850 RPM, which is pretty good for a budget cooler. Though it is – unsurprisingly – outdone by Arctic’s competing A35 series coolers. The AK400 Digital achieves its maximum cooling performance with total system noise levels of 41.4 dBA, the 2nd quietest result I’ve recorded on this system thus far. This is a moderate noise level comparable to that of a quiet hum. This level of noise shouldn’t bother anyone.Most loads that common users run won’t use more than 100W, so this is a better analogue for a worst case scenario of what folks might actually see in day to day usage with AMD’s Ryzen 7700X. Some of y’all might notice that the graph starts at 35 instead of zero – this is because my sound meter cannot measure noise levels lower than 35 dBA. Since that is the noise floor of this meter’s recording capabilities, 35 dBA is the “zero” for our testing purposes. For those concerned that this might distort results – there’s no worry. If anything, the graphs above will minimize the differences in noise levels because dBA measurements are logarithmic.
Established in 1996, DeepCool is a global brand in designing and manufacturing high-performance computer components for enthusiasts worldwide that includes CPU coolers, PCarray heatsink combined with a high-performance DeepCool 120mm FDB PWM fan provides the perfect balance between noise and performance. With an impressive heat dissipation power The compact size of the AK400 allows full compatibility with other components and ensures compatibility with a wide variety of cases at 155mm tall.
