Fan vs Passive Cooling Comparison
Cooling System
The ANYOYO 40Gbps Fan-Cooled M.2 NVMe Enclosure uses an active cooling approach with a PWM turbo fan and an aluminum alloy shell. This design allows the fan to automatically adjust its speed to maintain normal temperatures while operating at a relatively low noise level. In contrast, the ANYOYO NVMe M.2 SSD Enclosure relies on passive heat dissipation. It features a deep-groove fin design and includes silicone thermal pads to absorb and dissipate heat through the aluminum housing. This method ensures zero-noise operation, which keeps your creative workflow uninterrupted without any moving parts or fan noise to worry about.
Transfer Speed
Both enclosures support a maximum host interface speed of 40Gbps, compatible with Thunderbolt 4, Thunderbolt 3, and USB4. However, their real-world performance differs slightly based on the internal controller chips. The fan-cooled model uses JHL7440 and RTL9210 chips, achieving read and write speeds up to 2700MB/s. The passive cooling model utilizes the ASM2464PD chip, which allows for lower power consumption and higher peak speeds of up to 3100MB/s. If you frequently move large files like 8K footage, the passive model offers a faster top speed, provided you have the necessary Thunderbolt 4 or USB4 cable and device.
Build and Dimensions
The physical dimensions and weight of these enclosures vary significantly. The fan-cooled unit measures 4.65 inches in length, 2.24 inches in width, and 0.71 inches in height, weighing 5.86 ounces. It comes in Space Gray. The passive cooling enclosure is slightly longer at 4.72 inches and wider at 3.74 inches, with a height of 1.57 inches. It is available in Black or Silver. The passive model is bulkier due to its deep-groove fin structure, which increases surface area for better heat dissipation. If portability and a lower profile are priorities, the fan-cooled model is more compact and lighter.
Compatibility
Both products support the same drive interfaces and form factors. They are compatible with M.2 NVMe SSDs in 2230, 2242, 2260, and 2280 sizes, supporting both M-Key and B&M Key layouts. Neither supports SATA NGFF or mSATA drives. Both handle maximum capacities of up to 8TB. On the host side, both work with Windows, macOS, and Linux. The passive model explicitly lists compatibility with Android systems and Apple M1/M2 Pro/Max chips, while the fan-cooled model highlights tool-free installation and broad OS support without mentioning Android. Both require no drivers for basic operation.
Installation Style
Both enclosures feature tool-free installation designs, making it easy to insert your M.2 NVMe SSD without needing screwdrivers or extra hardware. The fan-cooled model allows you to slide open the cover and secure the drive quickly. The passive cooling model also uses a slide-open cover mechanism for the same purpose. While the installation process is identical in convenience for both, the passive model includes a 50cm 40Gbps cable in the box to ensure you can achieve its peak 3100MB/s performance. The fan-cooled model does not mention including a specific high-speed cable, so you may need to source one separately for optimal speeds.
Choose your ANYOYO enclosure
Users needing silent operation
If you prioritize a completely quiet workspace, the passive model is your best choice. It uses a deep-groove fin design and thermal pads to dissipate heat without any moving parts. This ensures zero-noise operation, which is ideal for creative workflows or professional environments where fan sound would be disruptive.
Users prioritizing compact portability
The fan-cooled enclosure is smaller and lighter, measuring 2.24 by 0.71 inches and weighing 5.86 ounces. Its Space Gray aluminum alloy shell and tool-free design make it easy to carry in a bag. This compact form factor is better for users who need a highly portable solution for their M.2 NVMe drive.
Users needing maximum thermal headroom
Active cooling provides a distinct advantage for sustained high-speed transfers. The PWM turbo fan automatically adjusts speed to maintain normal temperatures, protecting the drive from thermal throttling. This active approach helps extend the lifespan of your SSD during intensive tasks, ensuring consistent performance even under heavy loads compared to passive dissipation.
