Alphacool Announces NexXxos HPE ST-20mm Slim Radiator
Alphacool's NexXxoS HPE radiator is now also available as ST20 variant. The compact slim radiator can be mounted very flexibly and space-saving even in the tightest cases due to its low height of only 20 mm.
Technically and functionally, the NexXxos HPE ST20 is comparable to the HPE-30 and HPE-45 versions. All water-bearing parts and the cooling fins are still made of pure copper. The number of water channels and copper fins inside the radiator has been increased with the result that a larger volume of water is now in direct contact with the cooling fins and the cooling surface is used much more efficiently. Thanks to the technical innovations, the heat transfer has been improved enormously compared to the previous NexXxos models and the cooling performance has been increased significantly.
The NexXxoS HPE ST-20 radiator is offered in the common variants (120/140/240/280/360 mm) for 120 mm and 140 mm fans.

and the increase of 3 FPI, 16 to 19 FPI.
It may prove useful in cases where the top 280 radiator is obstructed by the motherboard VRM.
Or one could slap two of them together for 40mm total.
Personally, I doubt that works. More fins means thinner fins. Thinner fins means lower capacity to absorb heat. I'm sure it works as a slim radiator, but I'm also sure it's not as great as the marketing statement says.
Also means more air restrictive
But this thing is less than the thickness of a normal 120-140mm fan, I to don't see it doing much cooling wise.
Hardware labs gts series I believe is best thin rad at 29.6mm thick designed for low rpm fans.
basic principles here...more thin fins in a radiator dissipates heat better than less fins of thicker metal. If thin fins didn't matter, every radiator would just have water tubes and no fins or 6 fpi would be sufficient (which it isn't).
