This dakkza cooling 30mm case PC review focuses on the DAKKZA 30mm 5V Slim Brushless Fan. It is a compact cooling solution designed for tight spaces. The fan measures 30mm x 30mm x 7mm. It operates at a rated voltage of 5V with a current draw of 0.15A. These two specs define its power profile and physical footprint. The unit includes a cable for direct connection. It is built for low-profile applications where standard fans do not fit. You get one piece per package.
What stands out
- Ultra-slim 7mm thickness fits restricted spaces
- 5V DC operation with 0.15A current draw
- 30mm x 30mm footprint with 34mm diagonal hole distance
- Brushless motor design for reliability
Who it fits
Good fit for
You should consider this fan if you need cooling for narrow components. It suits 3007 form factor slots in small form factor PCs. It works well in air purifiers, amplifiers, and power adapters. The 5V rating matches many low-voltage systems. If your chassis has a 30mm x 30mm x 7mm opening, this unit fits perfectly. It is ideal for users who need specific dimensions rather than high airflow.
Who should skip it
Skip this option if you need high static pressure for dense radiators. This fan is not designed for standard 120mm or 140mm mounts. It lacks PWM control, so you cannot adjust speed via motherboard software. If you require higher airflow for gaming rigs, this slim design will not suffice. It is also unsuitable for systems requiring 12V power inputs. Look for a larger fan if your case does not support 30mm slots.
Verdict: The DAKKZA 30mm fan is a precise tool for specific low-profile cooling needs. It fits well in constrained spaces but offers limited versatility.
Key specs explained
Fan Size: 30mm
This dimension defines the square footprint of the fan. A 30mm width fits into very small mounting holes or slots where standard 120mm or 140mm fans cannot go. You should look for this size when upgrading airflow in narrow chassis sections, small form factor builds, or specific component cooling spots that require minimal lateral space.
Dimension: 30mm x 30mm x 7mm
The height of 7mm makes this a slim 3007 style fan. This thin profile allows installation in tight gaps between components or inside thin panels. You benefit from this when space is extremely limited. Compare this slimness to standard 25mm thick fans to understand why this model is better for crowded or shallow enclosures.
Rated Voltage: 5 V
The fan requires a 5-volt power source to operate. This is a standard low-voltage rail found on many motherboard headers and power supplies. You need to ensure your power delivery system provides stable 5V. This spec matters because using incorrect voltage can damage the fan or prevent it from spinning at all.
Rated Current: 0.15 A
This value indicates the electrical current the fan draws during normal operation. At 0.15 amps, the power consumption is low, which reduces heat generation and strain on your power supply. You can safely connect multiple units to a single header without worrying about exceeding typical current limits found in standard PC power distributions.
Diagonal Hole Distance: 34 mm
This measurement is the distance between opposite mounting holes. It ensures the fan aligns correctly with the screw holes in your case or component. You must verify this distance matches your mounting surface. If the diagonal distance does not match, the fan will not fit securely, leading to vibration or improper installation.
Build dimensions and mounting specs
The listing describes the DAKKZA fan as a 3007 model with a 30mm x 30mm footprint. The thickness is listed as 7mm, which converts to 0.28 inches. This slim profile allows the unit to fit into tight enclosures where standard fans are too bulky. You can use it in computers, air purifiers, amplifiers, and power adapters according to the product usage notes. The small size makes it suitable for equipment with limited internal depth.
Mounting relies on four holes arranged in a square. The diagonal hole distance is 34mm, while the parallel distance is 24.5mm. Each hole has a through-hole diameter of 3.7mm. These measurements help you verify compatibility with existing chassis or device frames. You should check these distances before installation to ensure the screws align correctly with your target hardware. The listing does not specify the material of the frame or blades, so you should assume standard plastic construction unless stated otherwise.
The fan uses a 5V DC power input with a rated current of 0.15A. This low power draw suggests it is designed for small components that do not require high-speed airflow. The brushless motor type indicates a design focused on longevity and reduced noise. You will need to provide a 5V power source to operate it. The included cable connects directly to your system. There are no external controllers or speed switches mentioned in the specifications. You should plan your wiring to connect this fan directly to a compatible 5V header or adapter.
Setup and everyday use guide
Installing this fan requires matching its physical dimensions and electrical ratings to your power source. The unit measures 30mm by 30mm with a thickness of 7mm. You must ensure your mounting area accommodates these exact dimensions. The listing provides specific hole distances for secure attachment. The diagonal hole distance is 34mm, while the parallel hole distance is 24.5mm. Each through-hole has a diameter of 3.7mm. Verify that your chassis or device frame has holes matching these measurements before proceeding. Electrical setup involves connecting the fan to a 5V DC power supply. The rated current is 0.15A, so your power source must support this load. The fan comes with a cable, which simplifies the connection process. You do not need additional adapters if your system provides standard 5V output. In daily use, this fan is designed for equipment that requires compact cooling. The specifications indicate suitability for computers, air purifiers, amplifiers, and power adapters. It is also listed for use in frequency converters, projectors, and welding machines. The slim 3007 form factor allows it to fit into tight spaces where larger fans cannot. You should check that the airflow direction aligns with your cooling needs. The brushless motor design suggests consistent operation over time. Always ensure the power connection is stable to maintain optimal performance. This fan is not intended for high-airflow applications but rather for targeted cooling in constrained environments. Its small size makes it ideal for internal components that generate moderate heat.
Before you buy this fan
You need to verify your power source provides a stable 5V output. The rated current is 0.15A, so ensure your connector can handle this load without overheating. Check the hole distances carefully. The diagonal distance is 34mm and the parallel distance is 24.5mm. The through-hole diameter is 3.7mm. Your mounting surface must align with these specific measurements. Standard 30mm fans often have different spacing. This unit is a 3007 model, meaning it is very thin at 7mm. Do not force it into a standard 3010 slot. It may not fit. You might need custom brackets or spacers if your case lacks pre-drilled holes for this exact footprint. Keep the area clean. Dust accumulates quickly on slim blades. Use compressed air to remove debris. This fan suits tight spaces like small form factor cases or electronics enclosures. It is not for high-airflow needs. Compare it with larger options if you need more cooling power.
Check before you buy
- Confirm your power supply outputs a stable 5V.
- Check diagonal hole distance is 34mm.
- Verify parallel hole distance is 24.5mm.
- Ensure mounting surface has 3.7mm holes.
- Confirm 7mm thickness fits your enclosure.
