The coolers are $27 on amazon.

I have no idea where you got that they cost $66, but they are less than half the price of a cheaper Noctua cooler and a third of the price of your cooler.

The product itself is listed as "Amazon Basics Computer Cooling Fan with Cooler Master Technology", as well.

Since the article does a poor job of saying it, they cost $27 in the US.
