The fin surface of the cooler is very large due to the single tower design, so that a lot of heat can be passed on to the air flowing through. The base is reasonably flat for what it is worth, but there are ridges for the simple fact this heatsink has direct contact heatpipes.

With a 50,000-hour rated operational lifespan for the FDB fan, DeepCool looks to be middling for a budget cooler in that number.An all-black variant of our highly compatible AK400 CPU cooler featuring a direct touch, four heat pipe tower layout with a unique black matrix fin design and a high-performance FDB fan that delivers excellent heat dissipation and extremely low noise levels.

Here, we can see the configuration of the heatpipes with respect to the base due to its direct contact heatpipe design. Nevertheless, this is a strong thermal result for DeepCool when its new AK400 is running at perfectly tolerable noise levels.

In terms of accessories, DeepCool includes mounting hardware for modern Intel and AMD mainstream platforms. Its sleek design and advanced technology offer silent operation and enhanced cooling, making it an ideal choice for gamers and PC enthusiasts seeking top-tier performance and reliability. And that’s particularly true when factoring in the Arctic cooler's warranty which is vastly superior to the coverage offered by DeepCool.

While the user manual clearly indicates the tools to use for certain sockets, I do wish the bags had clearly labeled Intel and AMD tools apart.

Can anyone provide a technical explanation or anecdotal evidence either to back this up or refute it? The speed range on the 4-pin PWM control curve is 500-1850 RPM, which is pretty good for a budget cooler. Codenamed Conroe and officially titled Intel Core 2 Duo, it’s loosely based on the current mobile Yonah (Core Duo) underpinnings. Without the fan, the tower on its own has measurements of approximately 152mm in height, 120mm in width, and 45mm in depth.While this is a small – almost immaterial – drop in cooling performance, it does have to be viewed through the lens of the competition. But the slightly more limited fan speed curve, higher full-speed noise output, and poorer warranty versus the likes of SilentiumPC and Arctic competitors dampen our feelings towards the AK400. With some quick measurements and calculations, the total surface area of the heatsink comes out to around 0. We saw a delta temperature reading of 68C at full fan speed, which puts its performance at the same level as Arctic Freezer A35 A-RGB. Performance from DeepCool’s budget AK400 is solid when tasked with a manually overclocked Ryzen 9 5950X processor.

With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two! Based on the specifications, this fan should be able to work well for this cooler, so I personally feel there is no need to swap it out.But it is important to note that some direct competitors already run quieter than this reduced fan speed level out of the box. The smooth-running fan motor ensures reduced vibrations and, in conjunction with the bearing, ensures a very long service life.

This ensures that the CPU has had ample time to warm up and reach steady state under all of the coolers.
