Overview of Thermalright Assassin X 120R SE V2
The Thermalright Assassin X 120R SE V2 is a more budget-friendly option, priced at C$23.59. Despite its lower price, it offers solid performance with a fan speed of up to 1550 RPM and an air flow of 66.17 CFM. This cooler is designed to handle the thermal demands of modern CPUs while ensuring a quiet operation, with a noise level rated at 25.6 dB(A).
This model also incorporates AGHP technology with four 6mm heat pipes, which helps mitigate the inverse gravity effect when installed in different orientations. Additionally, its height of 148mm ensures compatibility with medium-sized computer cases, making it an attractive option for those with space constraints. The Assassin X 120R SE V2 combines performance and affordability, appealing to users who may not require the highest-end cooling solutions.
Design and Build Quality
The build quality of the Thermalright Peerless Assassin 120 is notable, featuring an electroplated reflow welding process that enhances its durability and aesthetic appeal. The cooler's dimensions are 125(L)x135(W)x157(H)mm, allowing for an effective fit in various builds while maximizing cooling efficiency.
In contrast, the Assassin X 120R SE V2 is designed with practicality in mind, using industrial-grade PBT and PC materials to ensure a robust structure. Its height of 148mm fits comfortably in most medium-sized cases, making installation straightforward without obstructing RAM slots. While both coolers are well-constructed, the Peerless Assassin 120 offers a slightly more premium build quality, evident in its superior cooling area and design features.
Cooling Performance
When it comes to cooling performance, the Thermalright Peerless Assassin 120 excels with a thermal design power (TDP) of 245W, making it suitable for high-performance CPUs that generate more heat. Its dual-tower setup and six heat pipes work in tandem with two 120mm fans to provide effective cooling, reaching a maximum air flow of 66.17 CFM.
On the other hand, the Assassin X 120R SE V2 has a lower TDP capacity of 200W, which may limit its effectiveness for overclocked systems. However, it still manages to deliver a commendable cooling performance due to its efficient fan design and AGHP technology. Users looking for extreme cooling scenarios may lean towards the Peerless Assassin 120, while those with moderate cooling needs may find the Assassin X 120R SE V2 sufficient.
Noise Levels
Noise levels are an important consideration for many PC builders, and both coolers aim to provide quiet operation.
