Compare: Dark Rock Pro 4 vs AK620

Design and Aesthetics:

Dark Rock Pro 4

The Be Quiet! Dark Rock Pro 4 cooler has a cool and sleek design, with a matte black finish that makes it look awesome in any computer. It's built really well, which means it's good at keeping your computer cool and will last a long time. The top plate design may make it hard to see if the middle fan is working properly, but it's not a big issue for most people.

AK620

The AK620 boasts a dual-tower layout with two reasonably-sized aluminum heatsinks and a couple of FK120 PWM fans. Its design ensures excellent heat removal, allowing it to tackle even the most powerful processors. In terms of appearance, this cooler sports a sleek black top, two black fans, and a silver aluminum radiator, lending a refined look to any computer setup.

Install Notes:

Dark Rock Pro 4

Putting together the Dark Rock Pro 4 cooler can be tough, especially since it's a premium cooler. There are a few things that make it harder to install. First, it uses a metal bar to attach to the computer's motherboard, and it can be tricky to get it in the right spot. Second, the system for attaching the fan to the cooler isn't very easy to use because it doesn't have a helpful spot to lift the metal. You might need to use your nails or other tools to put the fan on, which makes it more complicated. Lastly, there's a metal plate at the top of the cooler that makes it look nice and helps with noise, but it also blocks your view of the middle fan and makes it harder to attach the cooler to the mount.

Because of its design, the Dark Rock Pro 4 cooler might be a better choice for people who have built computers before. If you're new to building computers, it could be pretty challenging. But there is a good thing about this cooler: it doesn't cause problems with fitting your computer's memory (RAM) in most setups, which is an issue with some other coolers.

AK620

The AK620 has DeepCool's more modern installation designs as of 2023, which has more components than most for an easy install. The backplates are held down by single hand screwed nuts that also serve to hold the mount from the other side. This makes it easy to place the backplate correctly during the installation. The remaining portion of the install is similar to that of Noctua's typical installation, which makes it easy, but also can make the uninstallation challenging if the thermal paste sticks well to the CPU.

Cooling Performance:

When it comes to keeping your computer cool, the Dark Rock Pro 4 is amazing with above average cooling performance. It's also one of the quietest coolers out there, which is great if you want a peaceful computer. It can handle really powerful CPUs and keeps everything cool, even when you're playing games or doing other hard tasks. It has two towers and two special fans that help get rid of the heat really well.

AK620

The AK620 delivers remarkable performance due to its six heat pipes that effectively move heat from the CPU to the extensive fin array on the heatsink. It is compatible with a variety of processors, even high-end ones with high TDPs. This cooler can handle challenging workloads and extensive overclocking, making it an appealing cooling option. For those seeking Noctua-like performance without breaking the bank, the AK620 is a strong contender.

Although this cooler might be louder than some alternatives of a similar size, its effective cooling makes it a strong candidate for your system. However, it's worth mentioning that some users may experience increased fan noise at mid RPMs occasionally.
