I do have a question about Sanyo: their product catalogue features all sort of PWM models in detail, yet the 9S1212P4M011 seems to have been omitted from anything but the complete part numbers list. What's the PWM curve like? Probably >=800 rpm at 10% duty cycle, I reckon?
That's about right. You might try a voltage-controlled SanAce, though. Newark only handles US sales. Outside of that, look at Farnell. Catalog says what you can buy in large lots. Stores have what you can buy individually. TBH I got my 8 Medium PWMs when a vendor ordered a little too many for a customer. Maybe you'll find one at a surplus site. Or try a mail order place like Farnell.

Yeah. As mentioned in an earlier post, trying to let a DC controller run PWM fans has yielded poor results for me, so that's out of the question. I just thought it might be something interesting for a CPU heatsink, but 120 mm @ 800-1000 rpm at idle is too noisy for my taste. Well, the number of wide RPM rage fans on the market is pretty decent at least, unlike several years ago.

@ashiekh: I appreciate the thought, however the Antec doesn't require rebuilding. It's barely three years old; I put up with the bearing noise until now as not to void the warranty.

Anyway, I'll keep researching datasheets and reviews for the time being and let you guys know once the whole fan swap operation is all done. I'm confident I should be able to make an informed decision based in your combined input.

PS: I've been trying to post a reply for the past two days, only to be shown an error message (500 internal server error) from the web server each time. How annoying.

Is there a reason you are not sending it back under warrantee?

Now I am confused; the Antec EA-430 does not seem to use a 120mm fan

Time, expense (international shipping) and the fact that the bearing noise wouldn't have been RMA-worthy given that I'm a silent freak and normal PC users probably wouldn't even notice. The Delta isn't broken or worn out, just a substandard example due to production lot variations. Also, there's no guarantee a, in terms of acoustics, "good" or better unit would have been returned to me.

There are two versions of the EA-430: https://gzhls.at/blob/ldb/e/4/4/0/43...33aaaf20a5.pdf

Yeah, and that's both odd and incorrect. There's definitely an AUB1212L in there as I can see the label through the exhaust vent.

Then return it on the grounds of false advertising; although one drop of oil will probably solve the issue.
