The Thermalright Peerless Assassin 120 is a popular CPU cooler known for its efficient cooling performance and reasonable price. Many users are curious about its noise levels during operation, especially when used in quiet or noise-sensitive environments. Understanding what to expect can help you decide if this cooler fits your needs.
Overview of Noise Levels
The Peerless Assassin 120 is designed to operate quietly while maintaining excellent thermal performance. Its dual-tower design with six heat pipes and high-quality fans contribute to both cooling efficiency and noise reduction. However, like all fans, some noise is inevitable, especially under heavy loads.
Typical Noise Levels During Use
In normal operation, the noise levels of the Peerless Assassin 120 are generally considered acceptable for most users. When idle or under light workloads, the cooler’s fans often run at low RPM, producing minimal noise that is barely noticeable. During intensive tasks such as gaming or rendering, the fans increase RPM, leading to higher noise levels.
Measured Noise Levels
Based on user reports and reviews, the typical noise levels range from approximately 20 to 30 decibels (dB) at low to moderate fan speeds. Under maximum load, the noise can reach around 35 to 40 dB, which is still within a tolerable range for most users.
Factors Affecting Noise Levels
- Fan Speed: Higher RPMs produce more noise. The cooler’s PWM control helps regulate fan speed based on temperature.
- Case Ventilation: Good airflow can reduce fan load and noise.
- Ambient Temperature: Higher room temperatures may cause fans to run faster, increasing noise.
- Fan Quality: The included fans are designed for quiet operation, but aftermarket fans can alter noise levels.
Tips for Minimizing Noise
- Ensure proper case airflow to reduce fan workload.
- Use motherboard fan control settings to optimize RPMs.
- Apply high-quality thermal paste to improve cooling efficiency, reducing fan speed.
- Consider aftermarket fans if quieter operation is desired.
Conclusion
The Thermalright Peerless Assassin 120 offers a good balance between cooling performance and noise levels. Expect quiet operation at idle and moderate workloads, with some increase in noise during heavy use. Its design and included fans make it suitable for users seeking effective cooling without excessive noise.
