I'm also wondering about the Vantec Stealth fans... I recently bought the 60mm for my NB cooler and I (surprisingly) can't hear it at all at 12v (erm, at least it's now quieter than the tri-cools on low and/or my vga and psu fans).

I don't see how, the enlobal bearing makes the fan hub magnetically levitated so I don't see any way that there could be problems with parts of the hub coming in contact with other parts making scratchy noises. My YLs do that, its annoying as hell, and one of them is actually STUCK in the position where the place where the blades are attached to the bearing are coming in contact with the motor, making TONS of scratchy noises.Originally Posted by Spanki

waiting on 28nm video cards...
I'll go see if I can find that again.. maybe it was only when they tilted it over like 45deg or something.
Edit #1: Hmmm... maybe I'm mis-remembering that. Anyway, I'm not sure I like the sound of this thing at 12v (measured 25cfm).
Edit #2: Aha.. I was thinking of the Global Win (Nanometer Ceramic Bearing) fan.

Been playing with many different fans with this issue as I wait for my DMM to come in....and positional noise differences seem random.
What I've observed is that there's no trend with sleeve bearings getting significantly worse when the airflow points straight up/straight down. Maybe this is a long-term issue? I have a couple fans that make a bit more extraneous noises when blowing sideways...and a couple that make a bit more noise point up/down. No real statistical trend on any of these fans that I'm noticing. None of these fans have been run long-term, however.
All my official testing is with fans point downward. All subjective noise comments are as well.....so take those for what they're worth....if a fan is extraneous-noise-free when I test it pointing downward, it really is (I guess...lol, I really honestly don't have any sort of trend here to be sure...heck, the Yate Loon sleeve bearings make no extraneous noise in any direction). Even when I hear a low click, the frequency of occurence is much too low to be a rubbing issue (I think)...and the low clicks I hear are practically inaudible....the dBA meter doesn't notice them, they're just a different noise.
I guess I'm not familiar enough with the geometry of how various bearings are constructed, but I'm guessing that the issue might come about due to any internal lubricant settling to one end of the shaft (?). This might affect a longer 'sleeve' type bearing, more than a relatively small/spherical ball bearing.
Anyway, thanks for the additional testing info - I didn't realize that you'd been testing horizontally.
From a physical viewpoint...that makes sense Spanki....hmmm, I'll have to think about it and do some research, but yeah, makes sense.
Oh, and I just organized my fans (room was becoming a mess with all the new fans coming in)
Each fan is a unique fan, and I'm missing three (or four, can't tell what one of them is) from my own collection (being used), plus I've left all of Baenwort's fans in their own box to not mix them up (about 15 fans).
is the Sunon u got from Petra is Sunon KDE1212PMB3-6A
i have one of them coming to me and i am planning to use on my BigTyphoon with a controller
i will be waiting for the results of this fan

I am very interested in the Nexus test. I ordered 8 of them a week ago for my watercooling rig and wanted to "keep it quiet, keep it cool".

Yeah, that's the one.
EDIT: also got the 3100RPM 120x120x25 version
aaww no silverstone fans to insult on fake specs, its a shame. looking forward to Minebea NMB fan reviews. I have that horizontal fan issue with my sleeve bearing silverstone casing fans. the yate loons are fine with it.
Just wondering, where can I pick up the ebmpapst fans? I can't find them at any of the usual places (PPCs, jab-tech, FCPU).
since they are not normally used for computer fans you have to get them from industrial stores bro.

Wow that's a crazy freakin price for a fan... but you get what you pay for I guess. I'll enitially get the YL's for my new build, but will later switch to either these or golfballs... wish Petras carried those..
i would go for the golfballs. they come with rubber fan mounts, 3 pin to 4 pin convertor, 1 cable tie(geezz), 4 fan screws.

I can't seem to find them at ppc's..... they listed under a different manufacturer?
i search ppc too i don't find them but you can email hank at ppc about them their supplier is alphacool in germany which has loads of them same place they get the sharkoons.
http://www.svc.com/r121225bl.html < silverstone FN121 case fans OEM !
i hope this is true cause i'm changing the order at PTS to SH instead.In yet other pieces of news....the YL SM at 12/7V does 55.3/35.8CFM and the SH does 76.6/49.3CFM. My ear and unofficial numbers say they're nice and quiet

a good read, thanks for this vapor.
and also cant seem to find papst at ppc.
PPCS carried them when Vapor first released his testing results. I can't seem to find them now. i guess he stopped stocking them. I remember he actually carried two different papsts as well.
I ended up going with the Sharkoon Golfball 2000's instead. However, I've since retired those for just regular ol YL LED fans instead.
PS, looks like Hank has been reading this site. I originally purchased 5 Sharkoon Golfballs for $15 fully sleeved. Seems prices have gone up since.

They should make this a sticky.
it was, now its not, cause vapor reasoned that stickied post does not get read as often as non stickied posts...
