DORHEA Case Fans at a Glance
The lineup splits into two clear groups based on size and use. The DORHEA 80mm 2-Pin DC Fans suit users needing high airflow for standard CPU coolers or radiators. These brushless units prioritize speed and cooling performance over silence. They connect via a simple two-pin interface, making them a practical choice for traditional PC builds.
The DORHEA 30mm Pi Fan 4-Pack targets a different niche entirely. These compact units are designed for Raspberry Pi 4 and Zero systems. Their low profile and flexible voltage options allow them to fit into small enclosures where larger fans cannot. This group is ideal for hobbyists building compact, single-board computer setups.
Who DORHEA Fans Suit Best
This brand targets two distinct niches with its current range. You can choose from tiny 30mm fans for Raspberry Pi devices or standard 80mm units for CPU coolers. The lineup covers small form factors and traditional tower heatsinks. All listed options are functional, with no RGB lighting or complex controllers included. You will not find 120mm or 140mm case fans here, nor do any models offer PWM control. If you need silent, large-case airflow or smart lighting, this brand does not currently offer those solutions. Stick to the 80mm or 30mm sizes for direct compatibility.
How to Choose the Right DORHEA Fan
-
Check Motherboard Headers
You must verify that your motherboard has the correct fan headers before purchasing. The DORHEA 80mm option uses a 2-pin DC connector, which is less common than the standard 3-pin or 4-pin PWM connections found on most modern boards. If your system lacks these specific headers, you may need an adapter cable. This ensures the fan receives the proper voltage and can spin at the intended speed without requiring additional hardware modifications or complex wiring setups.
-
Match Fan Size
Select the fan dimensions based on your cooling target. The 80mm model is designed for standard CPU coolers and radiators, offering higher airflow for traditional towers. In contrast, the 30mm unit is strictly for Raspberry Pi devices and small single-board computers. Using the wrong size will result in poor airflow or physical incompatibility. Always measure the available space in your case or on your heatsink to ensure the fan fits securely without obstructing other components.
-
Verify Voltage Needs
Ensure your power source matches the fan's voltage requirements. The 30mm Raspberry Pi fan supports both 3.3V and 5V inputs, providing flexibility for different board versions. The 80mm fan operates at 12V, which is standard for desktop PC components. Connecting a 12V fan to a 5V source will result in poor performance, while a 3.3V fan on 5V may cause damage. Check your device specifications to confirm the correct voltage supply is available.
-
Consider Noise Levels
Understand that these fans prioritize airflow over silence. The 80mm brushless unit is a high-speed option, meaning it will generate more noise than low-RPM fans. This makes it suitable for users who need maximum cooling performance for CPU coolers. The 30mm fan is described as quiet, making it better for small enclosures where noise is a concern. If you require silent operation, these models may not be the best fit for your primary workstation or gaming rig.
-
Assess Space Constraints
Check the physical dimensions of the fan against your available space. The 30mm fan is extremely low-profile, measuring just 0.3 inches in width, making it ideal for tight enclosures where standard fans cannot fit. The 80mm fan is larger and designed for more open spaces like radiator mounts. Ensure there is enough clearance for the fan blades to rotate freely. Proper spacing prevents vibration and ensures efficient air movement through your cooling system.
