Thermalright Assassin X120 Refined SEThermalright Assassin X 120R Digital

Design and build quality

The Thermalright Assassin X120 Refined SE features a robust construction designed to balance aesthetics with functionality. The unit incorporates a top cover design that aims to improve the overall appearance, combining high heat dissipation function with visual appeal. Materials include industrial grade PBT+PC components which contribute to durability. In comparison, the Thermalright Assassin X 120R Digital utilizes aluminum for the heat sink material, ensuring efficient thermal transfer while maintaining a manageable weight of 0.645kg. Both units reflect Thermalright's focus on computer accessories developed over more than 20 years.

Cooling technology and heat pipes

Central to the thermal performance is the heat pipe configuration. The Thermalright Assassin X120 Refined SE employs 4x6mm heat pipes that adopt AGHP upgraded 4th generation technology. This specific technology is designed to solve the influence of anti-gravity on heat transfer, ensuring consistent performance regardless of orientation. The Thermalright Assassin X 120R Digital also utilizes a heat sink structure compatible with standard cooling requirements, though specific heat pipe generation details are less emphasized in the provided specifications. The upgraded technology in the Refined SE model suggests a potential advantage in sustained load scenarios.

Fan performance and airflow

Fan specifications play a critical role in overall cooler efficiency. The Thermalright Assassin X120 Refined SE is equipped with a performance-level fan speed capable of reaching 2000RPM. This higher rotational speed allows for greater air movement through the heatsink fins. Conversely, the Thermalright Assassin X 120R Digital features a TL-C12C standard size PWM fan with a speed of 1550rpm±10%. While lower, this speed is paired with a maximum air flow of 66.17CFM. The higher RPM of the Refined SE model indicates a higher ceiling for active cooling performance when thermal demands increase.

Noise levels and acoustics

Acoustic performance is a key consideration for user comfort. The Thermalright Assassin X 120R Digital provides a specific noise level rating of ≤25.6dB(A), indicating a focus on quiet operation during standard use. The fan pairs efficient cooling with this low-noise-level profile. The Thermalright Assassin X120 Refined SE addresses noise through physical design choices, such as silicone corner pads around the fan which can reduce the noise caused by rotation to a certain extent. While the Refined SE lacks a specific decibel rating in the provided data, the inclusion of dampening materials suggests an attention to acoustic management.

Compatibility and dimensions

Physical dimensions determine case compatibility for both coolers. The Thermalright Assassin X120 Refined SE has an overall height of 151mm, which is described as compatible with most cases without sacrificing heat dissipation performance. The Thermalright Assassin X 120R Digital measures 125(L)x71(W)x148(H)mm. The slightly shorter profile of the Digital model at 148mm may offer marginally better compatibility in compact cases with limited CPU clearance. Both units utilize standard 120mm fan dimensions, ensuring broad availability for replacements if needed in the future.

Installation and mounting

Ease of installation is facilitated by included hardware and design choices. The Thermalright Assassin X 120R Digital is equipped with metal fasteners of Intel & AMD platforms to achieve better installation stability. This ensures secure mounting across major processor sockets. The Thermalright Assassin X120 Refined SE features a PWM function which can adjust the speed according to the temperature of the motherboard without manual adjustment, simplifying the setup process regarding fan control. Both coolers are designed to integrate smoothly into standard desktop configurations without requiring proprietary controllers.

Price and value proposition

Cost is often the deciding factor for budget-conscious builders. The Thermalright Assassin X 120R Digital is priced at $17.90, offering a lower entry point compared to the Thermalright Assassin X120 Refined SE at $22.90. This price difference of $5.00 makes the Digital model an attractive option for those seeking reliable cooling on a stricter budget. However, the Refined SE justifies its higher cost with advanced features like the AGHP 4th generation technology and higher fan speed capabilities. Users must weigh the immediate cost savings against the potential long-term performance benefits.

Which one should you buy?

Choosing between these two models depends on specific system requirements and budget constraints. If maximum cooling potential and advanced heat pipe technology are the priority, the Thermalright Assassin X120 Refined SE is the superior choice due to its 2000RPM fan and 151mm height. However, if value and verified low noise operation are more important, the Thermalright Assassin X 120R Digital offers excellent performance per dollar with its $17.90 price tag and 25.6dB(A) noise rating. Both units represent solid options from a brand with a pivotal influence in the player market.
