Price Comparison: ARCTIC P12 Pro PST vs. Thermalright PS120SE

The ARCTIC P12 Pro PST is significantly more affordable than the Thermalright PS120SE, priced at $9.49 compared to $35.90 — a difference of $26.41, or about 74% cheaper. This stark price gap reflects their fundamentally different roles: the ARCTIC fan is a single component designed for case or radiator mounting, while the Thermalright PS120SE is a complete CPU air cooler with heat pipes, heatsink, and dual fans. The ARCTIC fan’s low cost makes it ideal for users seeking an upgrade to their existing cooling setup without investing in a full cooler. In contrast, the Thermalright PS120SE’s higher price reflects its integrated design and advanced thermal technology, targeting those who want a ready-to-install solution for high-performance CPUs.

Performance & Cooling Capacity

The Thermalright PS120SE offers far greater cooling capacity than the ARCTIC P12 Pro PST, as it is engineered as a full CPU air cooler with 7 heat pipes and AGHP 4.0 technology capable of handling up to 280W TDP. This makes it suitable for high-end processors like Intel LGA1700 and AMD AM5/AM4 platforms. The ARCTIC P12 Pro PST, by contrast, is a standalone 120mm PWM fan designed for airflow rather than direct CPU cooling. It lacks any heat pipe or heatsink infrastructure, meaning it cannot function as a primary CPU cooler. Its performance is limited to improving case or radiator ventilation, not reducing CPU temperatures directly.

Fan Technology & Noise Levels

The Thermalright PS120SE features two TL-C12B V2 PWM fans rated at 1500rpm±10% with a maximum noise level of ≤25.6dB(A), indicating quiet operation under load. These fans are paired with S-FDB bearings for long-term reliability. The ARCTIC P12 Pro PST uses a single Fluid Dynamic Bearing (FDB) fan with a wider speed range of 600–3000 RPM and can stop completely at less than 5% PWM, which enhances quietness during idle. While both use advanced bearing types, the Thermalright’s dual-fan system provides superior airflow (66.17CFM max) and better thermal management across a larger heatsink surface. The ARCTIC fan’s focus is on smooth, silent operation within a narrow scope.

Build Quality & Materials

The Thermalright PS120SE uses anodized black frosted aluminum fins combined with a pure copper base, offering high thermal conductivity and durability. Its industrial-grade construction includes PBT + PC materials and UL Class A safety insulation, suggesting robustness for long-term use. The unit weighs 0.9kg and stands 154mm tall, fitting most mid-tower cases. The ARCTIC P12 Pro PST, while built with precise manufacturing and automatic balancing for minimal vibration, is a single fan made of standard plastic and metal components. It lacks any structural integration beyond its own housing, making it inherently less durable as a standalone component compared to a full cooler.

Compatibility & Installation

The Thermalright PS120SE supports a wide range of CPU sockets including Intel LGA1700, 1150, 1151, 1200, 1851 and AMD AM4, AM5, with included mounting hardware for each platform. This broad compatibility ensures it fits modern and legacy systems alike. The ARCTIC P12 Pro PST is a universal 120mm PWM fan with no specific CPU socket requirements — it’s designed for general case or radiator use. It requires no special installation beyond standard fan mounting, making it easier to integrate into existing builds. However, it cannot replace a CPU cooler entirely, so users must already have a functional cooling system.

Use Case & Target Audience

The ARCTIC P12 Pro PST is best suited for users looking to enhance airflow in their case or improve radiator efficiency, especially in systems with dense mesh panels or tight spaces. Its high static pressure and quiet FDB bearing make it ideal for passive or semi-passive cooling setups. The Thermalright PS120SE targets users building or upgrading high-performance desktops, particularly those with demanding CPUs that require robust air cooling. It’s ideal for gamers, content creators, and overclockers who need reliable, sustained cooling without relying on liquid solutions. The ARCTIC fan serves as an accessory; the Thermalright cooler is a complete solution.

Which should you buy?

Choose the ARCTIC P12 Pro PST if you’re looking for a budget-friendly, quiet, high-static-pressure fan to boost case or radiator airflow — especially if you already have a CPU cooler and want to improve overall system thermals. At $9.49, it’s about 74% cheaper than the Thermalright PS120SE and excels in precision engineering and silent operation. Opt for the Thermalright PS120SE only if you need a full, high-capacity CPU air cooler with 7 heat pipes, dual PWM fans, and support for modern platforms like LGA1700 and AM5. Despite its $35.90 price tag, it delivers comprehensive cooling performance and long-term reliability through AGHP 4.0 technology and S-FDB bearings. For a complete CPU cooling solution, the Thermalright is unmatched — but for a simple fan upgrade, the ARCTIC is the smarter value.
