Overview of the Products
In this comparison, we examine the Thermalright AXP-120-X67 Black ARGB Low Profile CPU Air Cooler and the Thermalright Peerless Assassin 120 Mini Black CPU Cooler. The AXP-120-X67 is priced at $32.59, while the Peerless Assassin is available for $34.39, making the AXP-120-X67 about 5% cheaper. Both products are designed for efficient CPU cooling but cater to slightly different needs and preferences.
Design and Build Quality
The Thermalright AXP-120-X67 features a low-profile design with a height of 67mm, making it a suitable choice for compact builds. It measures 123.5mm in length and 120mm in width. In contrast, the Peerless Assassin stands taller at 135mm and has a more traditional cooler design with symmetrical mech-type fins. The AXP-120-X67 utilizes aluminum fins on a copper base, while the Peerless Assassin boasts a fully blackened appearance with an antioxidant coating and a CNC precision micro-engraved copper base. This difference in aesthetics might appeal to users looking for either a subtle or a more striking appearance in their build.
Cooling Performance
When it comes to cooling efficiency, the Thermalright Peerless Assassin slightly edges out the AXP-120-X67. The Peerless Assassin's PWM fan can reach speeds of up to 1500 RPM, delivering an airflow of 66.87 CFM, while the AXP-120-X67’s fan can achieve a maximum speed of 1800 RPM with an airflow of 59 CFM. Despite the AXP-120-X67’s higher RPM capability, the Peerless Assassin's airflow performance is superior, potentially leading to more effective cooling. This performance can be critical for users looking to push their CPUs to higher limits.
Noise Levels
In terms of noise output, both coolers are designed to minimize sound levels. The AXP-120-X67 operates at a noise level of ≤26.1 dB(A), while the Peerless Assassin has a slightly quieter performance at ≤25.6 dB(A). This marginal difference could influence users who prioritize a silent operation in their PC builds. Both coolers are equipped with PWM fans that help maintain low noise levels while ensuring adequate cooling.
Compatibility
Compatibility is an essential factor when choosing a CPU cooler. The Thermalright AXP-120-X67 supports a wide range of Intel sockets, including LGA 1700 and LGA 2011, as well as AMD AM4. The Peerless Assassin also offers broad compatibility, supporting Intel sockets like LGA 1851 and LGA 1700, along with AMD AM4 and AM5. This makes both coolers versatile options for various builds, but the choice may ultimately depend on the specific socket type of the user’s CPU.
Installation and Ease of Use
Both coolers come with mounting kits that facilitate installation on various platforms. The AXP-120-X67 includes metal fasteners tailored for Intel and AMD platforms, ensuring a secure fit. The Peerless Assassin's mounting kit also provides the necessary components for installation and comes with instructions to guide users. While both coolers are relatively easy to install, users might find the AXP-120-X67 more convenient due to its low-profile design, making it easier to fit in tighter spaces.
Brand Reputation
Thermalright has established itself as a reputable brand in the cooling industry, boasting over 20 years of experience. Both products reflect the brand’s commitment to quality and performance. The AXP-120-X67 is particularly well-regarded in the low-profile segment, making it a popular choice among compact PC builders. Meanwhile, the Peerless Assassin is recognized for its efficient cooling capabilities, appealing to gamers and performance enthusiasts. This brand reliability may influence buyers’ decisions based on their past experiences or brand loyalty.
Price Consideration
The Thermalright AXP-120-X67 is currently priced at $32.59, while the Peerless Assassin comes in at $34.39, marking a price difference of $1.80. This makes the AXP-120-X67 about 5% cheaper than its counterpart. For budget-conscious consumers, this price difference may be a deciding factor, especially if both coolers meet their performance needs. However, considering the performance benefits of the Peerless Assassin, some users may find the additional cost justifiable.
Which should you buy?
Choosing between the Thermalright AXP-120-X67 and the Peerless Assassin largely depends on your specific needs and preferences. If you require a low-profile cooler for a compact build and are looking for a more budget-friendly option, the AXP-120-X67 is an excellent choice.
