I do not understand the usage of the Frore air jet system, 2 modules are almost twice the size of the SSD itself.
Mainboards, Playstation, PCI cards, SSD enclosure, laptops and NAS are not originally designed to have room for this flat but wide cooling solution.
At 1.75Watts per module, using 2 modules is going to double the power usage of the SSD.

phision brochure on page 2 -> power -> TBD
crucial t700 1 tb consumes almost 12 watts at peak.
since this new controller is faster its safe to assume that phision based ssds will use more than 12 watts.
3,5 watts to cool this down is ok and by no means doubling the ssd's power usage.

SSD processors produce a lot of heat in a 'tiny' area making it difficult to cool.
I have a USB to NVME converter with a 1TB Gen3 PCIE SSD.
There is a ribbed heatsink larger than a single face of the SSD to cool it.
When doing sustained writes for more than 10 minutes this can get pretty hot and if air isnt blown at the heatsink, the write will fail and the SSD controller will vanish from device manager until the PC is rebooted.
Annoying but it has continued to work perfectly again when cool enough.
I keep a fan near the PC for when I am writing to this drive to prevent the above problem.
Is a great cheap and simple enough solution.
But this being a Gen3 PCIE drive means it produces WAY less heat and in a larger area than the more modern drives.
I'm not at all surprised modern drives are much more difficult to cool.
imo, better positioning of M.2 slots and larger heatsinks are a preferred solution.
Slight airflow over a large finned heatsink can dissipate a lot more heat.
The solution is simply better engineering design, for now ...
