Size and Compatibility

The DORHEA 3007 Fan is designed specifically for compact devices like the Raspberry Pi 5, with a 30x30x7mm form factor that fits standard cases. Its small size makes it ideal for embedded projects where space is limited. In contrast, the ARCTIC P12 Pro PST is a full-sized 120 mm fan built for larger PC chassis or CPU coolers. The DORHEA fan connects via a 2-pin interface directly to the Raspberry Pi’s motherboard, while the ARCTIC fan uses a 4-pin PWM connector meant for desktop systems. This means the DORHEA fan is only compatible with Raspberry Pi models B, B+, A+, 2, 3, 4, 5, and Zero/Zero W—ideal for hobbyists using single-board computers. The ARCTIC fan, however, is not suitable for such devices due to its size and connector type.

Cooling Performance and Speed Range

The ARCTIC P12 Pro PST offers significantly higher cooling performance with a speed range of 600–3000 RPM, allowing it to deliver strong airflow even under resistance from dense radiators or mesh panels. It can stop completely at less than 5% PWM input, which enhances quiet operation during low-load scenarios. The DORHEA 3007 Fan operates at a much lower speed range, though exact RPM values are not specified in the data. However, it runs quietly at 15.92 dBA, making it suitable for noise-sensitive environments. While the ARCTIC fan excels in high-performance cooling tasks, the DORHEA fan is optimized for passive thermal management in small electronics rather than aggressive heat dissipation.

Noise Levels and Bearing Technology

The DORHEA 3007 Fan produces a measured noise level of 15.92 dBA, indicating very quiet operation—ideal for use in close-proximity setups like home automation hubs or retro gaming consoles. It uses a Hypro Bearing, which contributes to its long life of 30,000 hours. The ARCTIC P12 Pro PST features a Fluid Dynamic Bearing (FDB), which reduces friction and noise during operation, ensuring smooth and reliable performance over time. Although the ARCTIC fan’s noise level isn’t explicitly stated, its FDB design and precision manufacturing suggest low acoustic output. Both fans prioritize quiet operation, but the DORHEA fan provides a specific decibel rating, giving users a clear benchmark for sound levels in sensitive applications.

Power Supply and Connectivity

The DORHEA 3007 Fan operates on DC 3.3V to 5V and starts at just 3V, allowing it to function with the Raspberry Pi’s onboard power delivery. It uses a 1-to-2 pin connector that splits one input into two outputs, enabling dual-speed control between 3.3V and 5V. This feature supports flexible installation across various Pi models. The ARCTIC P12 Pro PST requires a 4-pin PWM connection and operates within a broader voltage range typical of desktop systems. It includes a Y-cable splitter, allowing one controller to manage two fans simultaneously. Unlike the DORHEA fan, the ARCTIC model does not support direct integration with microcomputers like the Raspberry Pi due to incompatible connectors and power requirements.

Build Quality and Longevity

Both fans emphasize durability, but their construction reflects different use cases. The DORHEA 3007 Fan has a rated lifespan of 30,000 hours, which translates to over three years of continuous operation. Its Hypro Bearing helps maintain consistent performance over time. The ARCTIC P12 Pro PST features precise manufacturing with minimal gaps, automatic balancing, and high-precision measurement, all contributing to reduced vibration and longer service life. Its Fluid Dynamic Bearing further enhances reliability by minimizing wear. While both are built for longevity, the ARCTIC fan’s engineering focus on vibration reduction and balance suggests superior mechanical stability in high-speed environments.

Price and Value Comparison

The DORHEA 3007 Fan is priced at $5.99, making it about 37% cheaper than the ARCTIC P12 Pro PST, which costs $9.49. For users needing a simple, quiet cooling solution for a Raspberry Pi, the DORHEA fan delivers excellent value per dollar. The ARCTIC fan, while more expensive, offers advanced features like PWM control, high static pressure, and a redesigned blade profile—features that justify its premium price for desktop or server cooling needs. The DORHEA fan’s lower cost is especially advantageous when purchasing multiple units, as it comes with two fans and mounting hardware included. The ARCTIC fan’s higher price reflects its use in professional-grade cooling systems rather than embedded electronics.

Bestseller Rank and Market Positioning

The ARCTIC P12 Pro PST holds a bestseller rank of 12,134 in the CPU Coolers category, indicating strong market acceptance among desktop builders and enthusiasts. This ranking reflects its reputation as a reliable, high-performance fan for PC cooling solutions. The DORHEA 3007 Fan does not have a published bestseller rank, likely because it targets a niche audience focused on Raspberry Pi accessories rather than general PC components. Its lack of a visible ranking doesn’t diminish its utility—it simply serves a different segment of the market. The ARCTIC fan’s presence in top-tier rankings underscores its credibility in performance-driven environments, whereas the DORHEA fan remains a specialized, cost-effective choice for microcomputer users.

Which should you buy?

Choose the DORHEA 3007 Fan if you're cooling a Raspberry Pi 5 or similar single-board computer and need a compact, quiet, and affordable solution. At $5.99, it's about 37% cheaper than the ARCTIC P12 Pro PST and comes with everything needed for installation. It’s specifically engineered for Pi models and operates efficiently at low noise levels. Opt for the ARCTIC P12 Pro PST only if you require high static pressure, variable speed control up to 3000 RPM, and a 4-pin PWM interface for use in a desktop PC or CPU cooler setup. Its $9.49 price reflects its advanced capabilities, but it’s incompatible with Raspberry Pi due to size and connector differences. For Pi users, the DORHEA fan is the practical, cost-effective choice.
