    According to the official specs of the respective manufacturers, one is sleeve and the second is FDB. If the makers of the fans are wrong about the specs of their product, then I am wrong yes.
    Neither of them are FDB. Neither of them are sleeve.

    They're both rifle bearing always have been.

    Yate Loon does not have a separate part number for using a rifle bearing. The sleeve and rifle bearing is interchangeable.

    HA1225M12F-Z, likewise, is not an FDB. It's a rifle bearing. They're both rifle bearing fans.

    Seasonic states that the HA1225M12F-Z is FDB. On the other hand the part number of GW's CX450 refers to a sleeve bearing fan.

    As it seems I will have to do the extra step in my reviews and fully break down the fans as well, to find out their true bearings. I didn't do it in this specific review because I needed those samples intact. But I am curious as hell!

    Ask Seasonic for a data sheet.

    They are probably rifle bearing.

    Agreed. FDB is a very often abused term.

    Is this why Seasonic used San Ace "Silent" Double Ball Bearing fans on their X-series? Look up prices on those fans, 9S1212H101.
    CPU: Core i7 8700k, HT enabled, all 6 cores OC'd to 4.8GHz, Vcore = 1.24v
    Heatsink: Noctua NH-D15 with one NF-A15 1500 RPM PWM fan
    Motherboard: Gigabyte Z370X Aorus Gaming 7
    RAM: 4x16GB (64GB) Corsair Vengeance LPX DDR4 RAM 16-18-18-36@3200MHz, Vdimm = 1.35v
    GPU: MSI GeForce GTX 1080 DirectX 12 with 8GB 256-Bit GDDR5X
    SSD1: Samsung 840 EVO 500GB TLC; SSD2: SAMSUNG 860 EVO 1TB 3-bit MLC

    Wouldn't knowing the price of any fan actually be the best way of knowing how good it is compared to others? We can spend all day talking about bearings and oil and stuff, but why not just compare prices? I would think if there was a better fan for less money a manufacturer would be using it, and if there was a worse fan for more money they wouldn't use it.

    Seasonic either custom ordered a part, or they're full of shit. Probably full of shit though, as they're not the first PSU company to willingly or ignorantly sell a fan from a manufacturer as an FDB when it wasn't really. A general rule of thumb, if the fan isn't a Protechnic (or BeQuiet, as they're made by Protechnic) then either assume it's a sleeve bearing or open it up.



    Case fan wise, you used to be able to get Scythe S-Flex or Zalman ZM-F3 fans (same fan, different label) which were true to their word on being FDBs but they have since been discontinued.

    That's because they're going off what Yate Loon's directory says, and Yate Loon doesn't have a separate part number of Rifle vs Sleeve or Single Ball Bearing vs Double Ball Bearing.

    Please do, fan faking is probably more prevalent than 80+ Badge faking these days.

    Those are just rifle bearings.



    Awhile back Hardware Secrets tore a few fans apart and analyzed what bearing they posed and published the findings:

    https://www.hardwaresecrets.com/the-...ring-fdb-fans/


    There are more "fake" or "alternative" designs than what they list but that's pretty good list to go off of.


    So far, the only trustworthy brands for labeling their fans properly have been Scythe, BeQuiet, Silverstone, and Cougar. Some other companies like Phanteks, Noctua, Nosieblocker, Enermax, etc haven't lied about their fans bearing type but they do use some proprietary naming which doesn't lend itself to ease of understanding for consumers unfortunately.

    The problem is that the contractors don't normally have anyone on hand that knows the difference between fan bearings or can identify between them, and the OEMs will sometimes outright lie to the people buying and say that "This FDB costs $2 and is just as good as that FDB which costs $8." To the contractors, this looks like a bargain and they may think that paying for a Protechnic bearing (a proper FDB) is just paying for the name and that everything operates the same otherwise.
