Price Comparison

The Thermalright Assassin X 120R Digital ARGB White CPU Cooler is priced at C$28.39, while the Gamma A40 ARGB BK CPU Cooler comes in slightly higher at C$29.09. This C$0.70 difference may seem minor, but it reflects the distinct features and technologies each cooler offers. The Assassin X provides a more extensive array of functionalities, such as a digital screen for monitoring performance metrics, which might justify its lower price point when compared to the Gamma A40.

Design and Aesthetics

In terms of design, the Thermalright Assassin X features a sleek digital screen on its top cover, allowing users to monitor CPU and GPU temperatures in real time. This digital integration adds a modern touch to its overall aesthetics. Conversely, the Gamma A40 has a compact height of 133mm and a classic round dot matrix top cover, which, while stylish, lacks the advanced digital features of its competitor. The Assassin X, with its digital display, caters to users who appreciate a blend of functionality and visual appeal.

Cooling Efficiency

The Thermalright Assassin X is equipped with a high-speed 2000RPM fan and a robust heat dissipation system, including four heat pipes designed to enhance performance. This setup maximizes the cooler's efficiency, making it a strong contender for users with demanding cooling needs. In contrast, the Gamma A40 supports a maximum TDP of 200W, which is impressive for compact designs. However, it does not reach the same RPM as the Thermalright, potentially resulting in less effective cooling under heavy loads.

Installation Process

Both coolers offer straightforward installation processes that support mainstream Intel and AMD platforms. The Thermalright Assassin X boasts a user-friendly experience, especially when employing its TRCC software for the digital screen functionality. On the other hand, the Gamma A40 highlights its compact design as a feature that simplifies installation in tighter spaces. While both coolers are easy to set up, the Assassin X's software integration provides an added layer of convenience for monitoring system performance.

Noise Levels

When it comes to noise levels, the Thermalright Assassin X employs silicone corner pads around the fan to reduce operational noise, enhancing the user experience during intense gaming or work sessions. While the Gamma A40 does not specifically mention noise reduction technologies, the high-performance 100mm fan is designed to offer better performance than comparable compact coolers. However, without explicit noise-reduction features like those in the Assassin X, it’s difficult to determine its noise output under load.

Compatibility

The Thermalright Assassin X boasts wide compatibility, supporting dual platforms for Intel and AMD processors. This broad compatibility allows it to cater to a larger audience, making it a versatile choice for various builds. The Gamma A40 also supports mainstream Intel and AMD platforms, but its compact design may limit compatibility with larger cases, potentially narrowing its appeal to users with specific case constraints. Overall, the Assassin X edges out in this category due to its more extensive compatibility options.

Heat Pipe Technology

The Thermalright Assassin X incorporates AGHP (Advanced Gravity Heat Pipe) technology with four 6mm heat pipes to ensure effective heat dissipation. This advanced feature is particularly beneficial in preventing the negative effects of gravity on cooling performance. The Gamma A40, while also featuring a direct-touch 4-heatpipe system, does not specify similar advanced technology. This could give the Assassin X an advantage in terms of overall cooling performance and efficiency, particularly in varied mounting orientations.

Which should you buy?

Choosing between the Thermalright Assassin X and the Gamma A40 ultimately depends on your specific needs. If you value advanced features like a digital display, superior cooling efficiency, and broader compatibility, the Thermalright Assassin X at C$28.39 is the standout choice. However, if you prefer a compact design that fits into tighter spaces and supports a high TDP, the Gamma A40 at C$29.09 may be more appealing. Both coolers have their strengths, but the Assassin X clearly offers more in terms of innovation and performance for a slightly lower price.
