ACASIS 40Gbps M.2 NVMe SSD Enclosure with Cooling Fan (TBU405 Pro)
Our verdict: A certified Intel JHL7440 chip, an active fan and listed testing on M1, M2 and M3 Macs and iPad Pro.
The TBU405 Pro uses a certified Intel JHL7440 chip, an active cooling fan with a manual switch, and the listing says it has been tested with M1, M2 and M3 Macs and the iPad Pro. The Intel part is the point: it is a true Thunderbolt controller rather than a third-party USB4 bridge.
It takes first place because Mac users, who see the most trouble with unusual enclosure controllers, have the best reason to prefer a certified Intel chip. The fan helps hold speed on long transfers such as a multi-gigabyte video export, and the manual switch lets you turn it off for quiet work. The compromises are fan noise when it runs, and a listing that does not mention a long warranty.
Buy it if you edit video or move big project files on a Mac and want a Thunderbolt-certified chip. Skip it if you want a silent passive enclosure.
