Compare: Dark Rock Pro 4 vs Peerless Assassin 140

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.

Peerless Assassin 140

The Peerless Assassin 140 shares a similar design with other 140mm coolers from Thermalright, featuring two 140mm heatsinks paired with a 120mm fan at the front and a 140mm fan in the middle. The difference in fan sizes helps reduce RAM clearance issues, which are common with most 140mm air coolers. This model has a polished top and comes in an all-black design, though other color options may be available.

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.

Peerless Assassin 140

The Peerless Assassin 140 CPU cooler features installation components similar to many mainstream Thermalright designs, making it relatively easy to install. However, it encounters a challenge when uninstalling, as it doesn't allow for sliding or twisting to break the thermal paste seal. This can be problematic if the thermal paste creates a strong bond between the cooler and 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.

While the cooler offers similar peak performance to its competitors, its main advantage lies in its efficiency at lower RPMs, where it provides slightly better cooling. This translates to a noticeable edge in noise-to-performance ratio compared to smaller coolers, making it quieter under lower loads while still maintaining strong cooling capabilities.

Noise Performance:

Dark Rock Pro 4

Just like the name says, Be Quiet! makes coolers that are super quiet, and the Dark Rock Pro 4 is no different. It has special fans and ways to stop vibrations, so it keeps your computer cool without making a lot of noise. This is perfect if you want a quiet computer.

Peerless Assassin 140

Due to its larger fans, this cooler becomes more audible at higher RPMs. However, because the fans move more air, lower RPMs are generally sufficient for cooling under most moderate CPU loads, allowing for quieter operation without sacrificing performance.

Summary:

Dark Rock Pro 4

The Be Quiet! Dark Rock Pro 4 cooler is perfect if you want a powerful, good-looking, and really quiet cooler for your computer. It's great at keeping your computer cool and is easy to put in, so it's a top choice for all kinds of people who build computers, whether for work or gaming. Just keep in mind that the installation can be a bit more challenging than other coolers, especially for beginners.

Peerless Assassin 140

The Peerless Assassin 140 CPU cooler is easy to install, thanks to its design resembling other mainstream Thermalright models, but it presents a challenge during uninstallation as it doesn’t allow for sliding or twisting to break the thermal paste seal. It features two 140mm heatsinks, a 120mm fan at the front, and a 140mm fan in the middle, which helps reduce RAM clearance issues common with larger coolers. While its peak performance is on par with competitors, it excels at lower RPMs, offering better cooling and a superior noise-to-performance ratio compared to smaller coolers. Although more audible at higher RPMs due to its larger fans, the slower speeds still provide sufficient cooling for most moderate CPU loads, ensuring quieter operation without compromising performance.
