Pretty much you're doing the right thing... Look at the MTBF.

An off the shelf Hong Hua fan DOES NOT have an FDB in it. It's a long life sleeve. The customer (not you, but Corsair, etc.) has to specify whose bearing they want to use if they want to use something other than the fan vendors' own solution.

I can't say with 100% certainty, but I've been in the industry long enough to know that most customers are NOT going to specify the fan manufacturer use another manufacturer's bearing in a fan. Not to toot Corsair's horn, but they're probably one of a very few customers that asks for a specific make/model bearing.

While I haven't looked at either of their offerings in being a true FDB; I would just take the safe root and assume that everyone is using a rifle bearing or sleeve bearing until shown otherwise.

As I've found in my adventurers, even the same company using the same OEM, with the same label can offer a fan labeled as FDB that is a true FDB while another one is just a rifle bearing.
