Vantec 92mmx38mm Tornado fan

I was cleaning a Vantec Tornado 92mm fan of mine earlier (TD9328H) and decided to remove the sticker from the backside of the fan to see if I could lubricate the bearings. Well, when I removed the sticker I was met with a surprise, a second sticker underneath it with the name of another manufacturer.

The OEM of this fan (in my case at least) turned out to be Sunon and the model number is PMD1209PMB1-A.

I must say the specs between the two are a little different. It's interesting to note that the OEM rates it at a higher RPM with more air flow and a higher dbA than Vantec does. In my case though both ratings are a little off from what I'm seeing, as the fan I have here consistently spins at 5200-5400rpm, and is probably louder as well.

I don't know if this information will be useful or informative to anyone, but I thought I'd post it just in case.

Yep, the tornado is actually made by Sunon. And the rpm is actually within tolerance of either factory rating. I don't miss those screamers at all either. The only 120 mm fan I know of that comes close to them in annoying factor is my Sanyo Denki beast fan

Oh, the good ole Tornados!

I happen to like the maglev fans by Sunon...are you guys familiar with them?
I have very quiet 80mm maglev lying around the house lol

Yeah, the maglevs are pretty good fans.

I used to know a local distributor, I'll check their catalog to see if they make any 140mm fan nowadays...
