Team Group T-Force and T-Create NVMe SSDs at Computex 2024: Magnetic Stacked Heatsinks

[btarunr]

M.2-2280 SSDs are always smaller than they look in pictures, a quarter of the size of a DIMM, but we've come across some huge cooling solutions. One of the most interesting of these is the T-Force Dark Airflow 06 magnetic-stacked cooling solution. An extruded aluminium heatsink with its fins positioned sideways, has two flattened surfaces, one of which makes contact with the SSD, the other is equally flat, and can make contact with another such heatsink.

A 20 mm fan pushes airflow sideways through the heatsink. The heatsink is magnetized to help with the stacking. The Dark Airflow 05 is a more conventional fin-stack heatsink that isn't expandable, it uses a simple aluminium fin-stack to which heat is fed by two copper heatpipes. The T-Force GE Pro Gen 5 is an M.2-2280 drive that leads Team Group's gaming SSD lineup. It comes in capacities of up to 4 TB, with transfer speeds of 14 GB/s reads, with up to 11 GB/s writes. The T-Create I54 Ai Gen 5 is not far behind, with a 4 TB, and up to 14 GB/s sequential speeds on tap, with a large amount of SLC caching that should benefit AI workloads.

If you need a bigger heatsink just build a bigger one. They don't even appear to be using a thermal pad or paste between the two magnetic surfaces. Doesn't look like it would be overly efficient with that approach, but to cool a SSD is probably bit overkill anyway.

Exactly!
Magnetism is not a mechanism for thermal transfer!

The strange world of quantum mechanics just got a little stranger with the discovery that a magnetic field can control the flow of heat from one body to another. First predicted nearly 50 years ago, the effect might some day form the basis of a new generation of electronic devices that use heat rather than charge as the information carrier.

The research stems from the work of physicist Brian Josephson, who in 1962 predicted that electrons could 'tunnel' between two superconductors separated by a thin layer of insulator — a process forbidden in classical physics. The Josephson junction was subsequently built and used to make superconducting quantum interference devices (SQUIDs), which are now sold commercially as ultra-sensitive magnetometers.


In the latest work, Francesco Giazotto and María José Martínez-Pérez at the NEST nanoscience institute in Pisa, Italy, measured the devices’ thermal behavior — that is, how the electrons inside them transfer heat. The duo heated one end of a SQUID several micrometers long and monitored the temperature of an electrode connected to it. A SQUID consists of two y-shaped pieces of superconductor joined together to form a loop, but with two thin pieces of insulating material sandwiched in between (see figure); as the researchers varied the magnetic field passing through the loop, the amount of heat flowing through the device also changed. The effect was in line with a theory put forward by Kazumi Maki and Allan Griffin in 1965.

The device worked by partly reversing the heat transfer, so that some would flow from the colder body to the warmer one. “This is completely unintuitive,” says Giazotto. “People are used to thinking of heat as disorder, so how can you impose quantum order on it? Amazingly, a device with Josephson junctions can do that.”

I thought you used magnets to wipe data, not keep it cool.

Cool, I guess Team Group are making these heatsinks out of superconductors cooled by liquid helium, and all the LHe cooling apparatus isn't pictured!

Clearly, I can't afford these but maybe they'll come in handy for NASA, CERN, or some other research institute with easy access to superconductor cooling systems!
