Where can I buy a thin 140mm cooler?

Question

Cooling systems

I can't find a thin 140mm cooler for sale, not a standard one inch, but 13-15mm. The search is easy, but they are not sold anywhere. Why is that? Where have all the thin coolers gone?
For example: TY 14013R is nowhere to be found. Prolimatech Ultra Sleek Vortex 14 Slim Fan too. Rather, there are such lots in stores, but everywhere they are "out of stock" or "unavitable", respectively. Found only CRYORIG XT140 on Amazon. but for 32 dollars. Despite the fact that the same cooler of greater thickness costs only 17. I think 32 is an overprice against the background of the absence of analogues on sale. Ali has a similar situation. And in general, the search does not really understand what is needed there. Offers regular inch. Where did all the thin coolers go? Are they not released?
It is also necessary that this be more than one BUS sample at the OLKh. And that it would be possible to buy a few dozen of them.

Answer 1

Search Noctua.
They have the best coolers for all tasks (including non-trivial assembly), IMHO.
You can buy a 120mm adapter bed: Noctua NA-SFMA1 and install NF-A12x15 (15mm cooler) there.

Noctua at Computex 2019

The fan prototypes on display included slim 140x15, 80x15, 70x15 and 50x10mm A-series models as well as a 140mm counterpart of the NF-A12x25, all of which are on the roadmap for 2021

Answer 2

Ali, taobao, ebay, amazon, avito/olx to the rescue
