Price Comparison
The Noctua NH-U12A chromax.Black is priced at $134.95, while the Thermalright Peerless Assassin 120 Vision MAX ARGB Black is significantly more affordable at $57.69, making it about 57% cheaper. This considerable price difference may appeal to budget-conscious consumers looking for effective cooling solutions without breaking the bank. While Noctua is known for its premium build quality and performance, the Thermalright's lower price point offers a compelling option that could attract those who prioritize value.
Cooling Performance
When it comes to cooling performance, the Thermalright Peerless Assassin boasts a dual-tower design and a fan speed of up to 2150 RPM, which contributes to its superior cooling efficiency. Its six pure copper heat pipes coupled with a nickel-plated copper base ensure optimal thermal contact with the CPU. The Noctua NH-U12A, featuring dual NF-A12x25 120mm fans, also delivers top-tier performance in a 120mm size, but with a height of 158mm. While both coolers excel, the Thermalright's higher RPM and dual-tower structure may provide an edge in cooling under load.
Design and Aesthetics
The Noctua NH-U12A chromax.Black features a sleek all-black design, making it a stylish addition to various builds. Its proven premium heatsink design has garnered over 100 awards, indicating high regard in the PC community. On the other hand, the Thermalright Peerless Assassin distinguishes itself with a unique magnetic top cover that houses a 5-inch IPS LCD screen. This screen allows real-time monitoring of system parameters, which adds a modern touch to its aesthetic. While both coolers look impressive, the choice may come down to whether you prefer a classic design or a more modern, tech-savvy appearance.
Installation Process
In terms of installation, the Noctua NH-U12A comes with the renowned SecuFirm2 mounting system, which is designed for easy setup on a variety of Intel and AMD sockets. This user-friendly installation process is complemented by the included high-end NT-H1 thermal paste. Conversely, the Thermalright Peerless Assassin also offers compatibility with multiple Intel and AMD sockets, but its design may require a bit more attention due to the dual-tower configuration. Both coolers facilitate installation, but Noctua's reputation for user-friendly assembly may give it a slight advantage.
Noise Levels
Noise levels are an essential consideration for many users, especially in quiet environments. The Noctua NH-U12A is designed to operate quietly, with whisper-quiet performance at idle thanks to its PWM-controlled fans. Thermalright's Peerless Assassin, with its high-speed fans, operates at a maximum noise level of 27 dB(A). While this is relatively quiet, it may not match the ultra-quiet performance of the Noctua under less demanding conditions. For users prioritizing silence, the Noctua may be the better choice.
Compatibility
Both coolers offer excellent compatibility with mainstream ATX cases. The Noctua NH-U12A has a height of 158mm, ensuring it fits well without overhanging RAM slots or blocking PCIe slots on most motherboards. The Thermalright Peerless Assassin stands slightly taller at 164mm but is designed to accommodate tall RAM heat spreaders and GPU installations thanks to its offset design. While both coolers provide robust compatibility, the Noctua may have a slight edge due to its lower profile.
Warranty and Reliability
Reliability is a crucial factor when investing in a CPU cooler. The Noctua NH-U12A comes backed by a 6-year manufacturer’s warranty, reflecting the brand's confidence in its product quality. While the Thermalright Peerless Assassin does not specify a warranty period, its innovative design and advanced technology suggest a commitment to durability. For purchasers looking for long-term reliability, the Noctua’s extended warranty may offer peace of mind.
Which should you buy?
Choosing between the Noctua NH-U12A chromax.Black and the Thermalright Peerless Assassin 120 Vision MAX ARGB Black ultimately comes down to your specific needs and budget. If you have a higher budget and prioritize superior build quality, quieter operation, and a longer warranty, the Noctua may be the better option for you at $134.95. However, if you're looking for a more affordable solution that still offers excellent cooling performance and innovative features like an LCD screen, the Thermalright at $57.69 is a fantastic choice. Consider your cooling needs, case compatibility, and aesthetic preferences to make the best decision for your setup.
