i just got my first yate loon fan.. its not bad, somewhat, a woosh of sound i hear.
@ 7v how much rpm does the fan spin at for the yate loon fans?

Excellent thread!
I'd be interested in 80mm and 92mm fan results too, as they are still the cheapest way to move air. I'll even provide a Masscool 80mm fan for testing.
Okay, Panaflo LH, a famed San Ace, and another random 120x120x32 fan are officially ordered (IDK how fast that site moves stuff, but I figured I might as well jump on it).
I'm also pretty set on the two higher-speed SilenXs unless anybody says otherwise.
About the Deltas....anybody know of another non-wholesale place to buy them from? Sidewinder didn't have quite the selection I thought they did :-/ Maybe I should forego the Deltas?
And for the Enermax Warp....seems I can't find it in the states, but its little brother the Marathon (1000RPM) is readily available, so I'll go with that :)
You should be able to contact Sidewinder to custom order Deltas. I've had to in the past and they are very friendly about it. I haven't ordered from them in about a year but they should still be willing too.
im looking into the deltas I might have a few sites ill let you know...
Also didnt this thread used to be stickied???
Cool, didn't think of that, thanks Baenwort and demonbane23.
And yeah, it was stickied....but it's always been my opinion that unstuck threads get more views (honestly, in most sections I scroll right past the stickies) and I needed people's input on a few things :)
Ahh I got ya looking for the most input.
Well after some searching there are some sites that sell refurbs and one or two that want a nutty price like 25-30 a fan and then I also found like 7 or 8 of the WFB1212M 2100 RPM 72 cfm 34 db fans on ebay from electronic sellers.
They cheapest legit looking ebay seller with shipping the fan is like $7 bucks. If you want to pm me your shipping address I can pay for the fan for your testing and just put your mailing address for delivery. Id be willing to help you out to see it in the test just let me know.
Nah, I can't do that :)
I think I have an idea for a source though....if Sidewinder is unreasonable (doubtful) I can probably just talk to Swiftech, they probably have tons :shrug:
Awesome you got the enermaxes? :)
If they turn out to be good (which they probably will) I think I'll be building my next contraption, the ghetto overvoltage use only PSU :D
Definitely getting a Marathon....can't find either of the other two Enlobal models though :(
vapour are the epapst with a metal frame any better than the plastic framed ?
No clue :shrug:
Hi Vapor, thanks for the great comparison, appreciate the time you put into it. About the San Ace fan you're testing, what specific model is it? I'm using the San Ace 120mm x 38mm 109R1212H1011 Fan (0.52amps @ 12V, 102.5 CFM, 39dB, Static Pressure: 64.7Pa) and was wondering if that was the one you're testing. Thanks.
Yup, just checked my receipt, that's the one....couldn't get ahold of the 130CFM version IIRC...but this one will make do (heck, it's the one most of us care about anyway). :)
Great, thanks a lot. Looking forward to the update!Quote:

Okay, I just searched every store in Maxxx's sticky in WC, no luck :(
Any ideas? Even e-bay has 0 :(
thats cus i bought the medium speed yate loon off of jabtech, the last one :pQuote:

EDIT: just kidding, it's sold out too :rolleyes:
EDIT2: guess it'll have to wait....ordering the SilenXs and the big list in post 180 right now.
EDIT3: Petra to the rescue :bows:
Hmm.. I can't find any either, but have you looked at the Yate Loon Ball bearing fans? They have a low noise rating as well, so I'd be interested in knowing how it compares (for a top-tower fan, where horizontal mounting is required, sleeve fans are no good).
Yup, D12BL-12 has been ordered :)
Thanks. In the meantime, did you have any suggestions for horizontal-capable fans from earlier tests? I'd be looking for something to replace an Antec tri-cool on low setting, for example - so it would need to push at least that much air and be quieter :).
Actually... I think the loudest fan in my computer right now is the stock Intel HSF, so maybe I'll get that replaced before looking at the others.
Just got the San Ace (huge hub, competes with the 120VAC fan I have in my single stage), Panaflo LH (oooold school hyper-design [aggressive blade structure and positioning, but the old fashioned way]..., and a Comair Rotron MC12B7 120x120x32 (nice looking....draws a whopping .66A for 3700RPM and 102CFM [me thinks that this fan may be something special...]).
Awaiting round 2 :)
If I had more money and no mom to stop me I would've sent you fans or at least bought some and shipped to you...this is just awesome. Its surprising that before this, a lot of people's choices on fans were determined by "OOOOOOHHHH I have fan X and its AWESOME YOU NEED TO BUY IT!!!" "OOOOOHHH this fan is inaudible to me, its THE MOST QUIET FAN EVER!!! YOU NEED TO BUY IT!!!"
Good, bad, and ugly update.
Just playing with the new stuff now...accidentally fried my DMM, so I only have 12V and ~7V to test for now :rolleyes: Still fun to be back and testing fans though :)
New location from last time, so very, very different noise personality....old results will not be directly comparable....I WILL retest many of the fans however :)
Due to a WCG-inspired processor swap, the CPU temp comparison will also not be directly comparable (went from a Celeron D...GREAT for this purpose, not for WCG...to a Conroe). For various reasons actually....I'm considering flat out dropping the CPU temp test. Results were largely consistent with restricted CFM test and this test took freaking FOREVER (~1hr a fan for the first pass [some ~25% of the time, another 1hr 2nd pass was needed to verify/rectify data]). Near the end I could pull a test time down to ~30min after I got in a groove, but that was only because the Celly D was so forgiving with going passive on the TTBT. And I've also repurposed the thermal probe I was using for ambient temps....and the Conroe isn't nearly as flexible as the Celly D was for stability at high temps. So the long and short of it is that the CPU tests future are in jeopardy. Talk me in/out of it....I'm on the fence, leaning toward ditching them.
I've been playing with my three new fans, the Sharkoon, the FN121, the U1A, and the SHE Tri-blade.
1) the San Ace is just incredible, freaking incredible. At ~7V it preliminarily pushes more air quieter than the Sharkoon does at 12V. At 12V, it pushes ~115CFM, not the 103 that it's rated. I can't get it to drop to ambient noise levels....but that's okay considering it's a 115CFM fan, lol. Compared to the restested U1A, it pushes 1CFM more at 12V and at 1dBA lower. At 7V, it's 7CFM ahead and 1.5dBA quieter. FWIW, the U1A is getting extremely similar results to what it had before...and it was an 'All-Star' before too.
The Panaflo LH is old school to the max....old school noise, old school design....and old school performance :-/ At 12V, it's around 5.5dBA louder than the 7V San Ace, and pushes the same amount of air. Compared to the Sharkoon, it pushes ~1.5CFM less at 12V and 3.5dBA louder. The Sharkoon also fell victim to an approaching thunderstorm that increased ambients a lot :(...so that dBA data may be on the high side.
The Comair is the worst rated fan I have tested to date...they say it's a 102CFM fan, but I'm getting 129CFM out of it....but it's also loud. Quickly compared to the Delta SHE Tri-blade, it was a little louder.
The Silverstone FN121 is still putting up identical numbers from before....the Yate was in a case and I was too lazy to remove it, so no retest numbers on that yet. The Sharkoon is getting ever-so-slightly worse dBA numbers (for now...thunderstorm and one piece of electrical noise may have effected it)....but still better at 7V than the FN121 is at 12V.
Anyway, so yeah, a thunderstorm has rolled in so noise testing is useless....and CFM results compared to last time haven't changed even a tad on any of the fans.
Thanks for the update Vapor, I'm running 2 of those San Ace fans and they're great.
Which Sharkoon is that this time?
Same exact fan....Silent Eagle 2000 "Golfball"
Re-test.. ahh, cool.
Ah, yeah...sorry for any confusion. The Sharkoon, FN121, U1A and SHE are all retests.
..but I take it that it's still somewhat loud at ~5v? Sounds like it may not have enough lower range.Quote:
the San Ace is just incredible, freaking incredible. At ~7V it preliminarily pushes more air quieter than the Sharkoon does at 12V
Edit: hmm... just referenced your original chart again and it looks like the U1A gets down to YL 12v dbA range at 5v, so maybe there's some hope, if it's comming up quieter than the U1A at 7v.
At the very bottom of its working voltage range (4ishV), it was still audible...not loud, but if it were the only thing in the room, you'd notice it.
Can't get better/official numbers until I get a new DMM :-/ (or a new fuse, but I think it's time I get a new DMM anyway)
EDIT: just realized that made no sense above....lol. Anyway, with the thunderstorm, audio tests are useless....and if I wanted to plot the U1A vs. the San Ace, I'll need to get my DMM working anyway.
Ouch your multimeter broke...I hope it wasn't a good one :( i have a 10 dollar one :D
No problem :). On the cpu testing... that was one of the features that I really liked about your review. I'm not sure that the radiator numbers line up exactly (must be difference in the amount of impedence)...
If you look at the all-stars, adjusted db on radiator, at the 27-28db range (where the low speed fans top out), the FN121 is measuring just under 30cfm, the bottom end of the U1A is roughly the same (but a bit louder), and the YL is pushing ~4cfm more than either of those. But then when you look at the final chart (cooling processor, adjusted dba) at that same 27-28dba range, the FN121 is doing a better job on the heatsink than the YL (which was doing better on the radiator). It's only a couple degrees, but the radiator chart kinda paints a different picture, as it were :).
Maybe if the heatsink test is a pain, there's some other way to do a second test on the radiator with more/less impedence?
...of course the more interesting fans (to me, at least) are the medium speed ones, which seem to perform well in either case at that dbA level (with some breathing room on either side of that speed).
I like this idea...I'll see what I can rig up for a rig with more impedance (I have a mesh grate I'd like to use for a low-restriction setup).Quote:

I'll sleep on it.
Heck, I have a spare TTBT, I could do a CFM test on that too :hitself: (EDIT: actually, logistically, I can't....so nvm).
I have an idea. Instead of looking at the temps on the CPU, strap the heatsink on and measure the airflow. That way you can see which fans perform well with restriction, and without the hassle (because obviously, more airflow=better performance).
See, the thing about the heatsink test was to show deficiencies in certain designs.....yeah, some fans may get a lot of airflow, but if the hub is too big or the airflow is concentrated to only certain parts of the HSF due to funky blades, then it may not cool as well as a diffuse pattern of airflow or a small-hubbed fan.
Again, I'll sleep on it.....I may build yet another dedicated rig for this now that I think about it more....lol.
The things we do for that extra 1% :)
Good points as well. Blade and Hub geometry are kinda actually the big question here. Some folks claim that pretty much any fan turning at X rpm wil move the same amount of air as any other same-size fan spinning at X rpm... even though thier own testing data doesn't really support that claim.Quote:

Some fans have really large hubs, reducing the blade size... some have really small hubs (like the Scythe 100mm fans), allowing for larger blade sizes and then some (like the SilenX) have blade wrapped up onto the hub. Then you get to the 'scooped' fan blades, like used on a Cooler Master Hyper Tx, with a rounded/knob hub-cap, then you have your Golfball blades (with a fairly large hub), etc.
Is that all 'just' marketing gimmicks? Or does it make some measureable difference (ie. if it makes it quieter or at least more pleasing, maybe I can run it faster for more cfm compared to some other fan, etc.).
...true, but it's another data-point, that could be the (hypothetical) difference in:Quote:

...more data points help make better informed buying decisions :).
Okay, I'm keeping the CPU tests, but only going to do them at 7,9, and 12V.
Also of note is that today I started playing with my SilenX's and a few 140mm fans. The SilenX's aren't too bad....I've been having problems with inaudible (higher frequency than I can hear) ambient noise from SOME source that wasn't present last night that I have yet to find :( so no 'official' dBA numbers at all on these.
The 120x120x38 that claims 90CFM pushes 60CFM in my tests, while the 120x120x25 that claims 72CFM pushes 55.9ishCFM in my tests. They seem pretty quiet and undervolt fairly well (no extraneous noise). BUT, the motors get bloody hot....much hotter than even the monster Delta 190CFM EHE. They're aesthetically pleasing, though very light....kinda feel cheap because of the lack of weight. They are absolutely not magic fans.
My 140mm experience has been lackluster so far....I just can't get any of the Aerocools or even the Yate to pull their claimed CFM (the Yate being the furthest off). The Aerocools fall right at the +-10% they use as padding....so that's okay....but the Yate is puzzling me. The 14SM-12 claims 62CFM when I can only get ~43CFM out of it. It is exceedingly quiet....much quieter than the claimed 29dB (getting around 26.5 in the screwy ambient....). I'm wondering if I have a mislabeled and rare 14SL-12.
EDIT2: On-board RPM reading says 1100RPM on a sensor that over-reads by ~6% on every other fan I've tested (IDK how though....isn't that one of the simplest circuits?) Looks like I have a D14SL-12....ugh, lol
well you will see the exact same thing with the D12SM. i don't know why just my opinion but they don't push as much as their claim. 70cfm please....
I've also doubted the 70CFM @ 1650RPM (esp considering the D12SL does 48CFM@1350 with the same geometry [I think])....but 62@1400 (on a 140mm) is perfectly fine and expected. It just doesn't spin much faster than 1035RPM or so....and is frankly one of the nicest sounding fans @12V I've ever (not) heard. Has to be a mislabled D14SL-12....which is nice and all, but the SM variant is what I wanted to test....looks like I'll go fan hunting again.
Just got my PTS package today....Scythe Minebeas, Nexus 120mm, a couple Sunons, their version of the YL D12SL-12 clear blue, and BOTH the YL D12SH-12 and D12SM-12. The SM has been OOS everywhere, even PTS, but I talked to Alex and he had an extra and we agreed to (because PayPal is a PITA) order an SH and then swap with an SM at his side. Well Quoc included both and handwrote a nice note :)
In other news, I'm a dumbass.
Yesterday the USPS guy left one of those "I came, I rang, You didn't sign" notes on my door saying that the Jab-Tech package needed to be signed for....so I go to the Postal Office today at 1:30 and they're closed :(
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 :)
Oh, and the SM has the SL's blade geometry (I think...my SL is in a case and spinning right now, so I can't 100% verify that)...the SH has a different one.
Oh, and the Nexus 120mm D12SL-12 is INCREDIBLE in my prelim testings...:eek:
Oh, and on the Scythe Minebea's....on all three for 12V, I'm getting within .1CFM accuracy to their claimed CFM. Kudos to Scythe for having realistic CFM ratings! Not that mine are super-scientifically accurate, but .1CFM difference (at most) on all three fans....that says something, IMO. The dBA ratings, that's anothers story, BUT....very different environements as well.
yeah i checked out jab-tech large image view. I have SL & SM i looked they look exactly the same. hahaha good to know that the plastic bag test still works for me. OH then i should get SH instead since they will be having the SM ratings instead then.
Scythe Minebea's are by NMB Minebea. Scythe didn't even relabel the fans NMB deserves the credit there if thats true. Amazing stuff and thanks to scythe for providing the quieter smaller versions for computer users.
on a dumbass note from me. i got myself a scythe kamabay. the stock fan that comes with it spins at 800rpm. the kamabay has a mesh and a filter. so there is NO air coming thru. this is the most useless fan in the whole casing !
what do you mean with the nexus is incredible? higher cfm than expected, quieter than expected,...?
higher CFM, very, very little noise and what noise there is has to be the least obtrusive sound a a fan has ever made.....undervolts well too :)Quote:

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.Quote:

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)
http://img155.imageshack.us/img155/3062/fans1zl0.jpg
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.Quote:

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..Quote:

So...you're saying you'd rather people not read this thread now? :p:
i like this thread.. the reason i bought yate loon fans becuase of this :P
Speaking of Yate Loons, I just purchased a Stacker 832 and when trying to make a decision on 7 120mm fans it just made sense to go with Yates because of the price point. So my question is, with that many fans what model of Yates would one go with for optimal air flow and noise or would it make sense to put them all on a fan controller? Please help me decide as I just can't justify paying $15-$20 a piece for other models.
If you want blingy LEDs, get Petra's D12SL-12 w/ LEDs. Otherwise, just get the regular SLs, SMs, or SHs depending on your noise preferences.
Vapor, just want to say thanks for all your hard work for all of us here on the Xtreme, it's much appreciated.Quote:

Thanks again :up:
Well, running 7 of then would be nearly 9dBA higher than just 1 (regardless of which fan you choose, it'd be 9dBA higher). So 7 SLs will sound like 1 SH (or there abouts). This is past my tolerance for noise...but some people can take it (and then some).
7 SHs would sound loud...lol.
As for whether or not you want to put them on a fan controller, or in what groupings (I don't know of a fan controller that can do 7 individual channels). Again, that's up to you. I think fan controllers are great since your system won't be at full load 24/7 (unless you crunch and have no GPU....and in that case 7 fans may be excessive anyway, lol), so why keep your fans a full speed 24/7.
I've been doing a little digging around and came up with a fan controller that does control 6 fans although it's not adjustable via a rotary dial (being able to fully control the rpm's) just switch's that go from 12v, 7v and off. http://www.frozencpu.com/products/98...17&id=v7qNg76qQuote:

EDIT: well, damn....that design sucks. Rather than switching from 12V/ground (12V operating voltage) to a 12V/5V (7V operating voltage) to a 12V/open (off) setup, they have a semi-pwm setup :-/ Guess I'm still making my own (that will have nearly as much load handling as my PSU can...just simple switches, no crazy circuitry).
Sorry, what do you mean by the switches being weak?Quote:

It'll do the job for sure....BUT, the one I've been planning to make will have 12V/7V/off and be able to do ~250W per channel (technically it'll be limited by the PSU and wires). Just an extremely simple setup, no circuitry really, just a few wires and switches :)
I just found this http://www.sunbeamtech.com/index-2.html
looked at a bunch of reviews which were are all great and there only about $12
I guess I could run two of them.
What do you think?
Yeah, that Sunbeam is what a lot of us use....very good controller, though it wears over time when pushed with high-draw fans.
Vapor,
Thanks a lot for all your help, I think you've helped me make my decision. For only $12.95 for the controller and about $3.50 for the YL I think I'm in business.
You rock :D
@Vapor,
Have you tried stacking the open framed AC fan(it spins the opposite way)
on top of any other fans? (say an undervolted 3 blade delta)
I tried that in the beginning with just two 45CFM fans (Yate and the Scythe IIRC)....works well. I haven't tried with two counter-rotating fans (the Delta Triblade and the AC12 both spin in the wrong direction). I'll try the Delta Triblade LE and another similar fan....see what I can pull.
Also, the AC12 seems to be completely incompatible with my testbed. Either that or it sucks. Open framed Thermaltake worked okay and the reverse-spin Deltas were okay....but the AC12 just blows.
Just tried the Delta LE Triblade (72CFM) on top of a Sharkoon 2000....both at 12V. 103.7CFM, 40.7dBA, and 85.3CFM on the radiator (only a 17.8% drop!).
For comparison....the San Ace does 100.5CFM at 40.7dBA and only 71.8CFM on the radiator at that voltage (10V).
When the Sharkoon is placed on top of the Delta....both at 12V: 108.6CFM, 40.9dBA (higher pitched though), and 90.5CFM on the radiator (16.7% drop!)

Seriously though... that's odd. Maybe the turbulence pattern is just more defined with that one? Have you tried adding any kind of air-straighteners?
Hehe.. I was just going to suggest that you see if reversing the order made any difference and as I was typing that in, I noticed the quoted text had already been updated with the info. Interesting results!Quote:

The spinning turbulence is A LOT weaker than the Delta's. Deltas get negative CFM readings in push...heh, this one got positive readings, and up near ~15CFM (for a fan that spins the wrong way, that's really high, means very little turbulence).Quote:

I've tried just placing it on the case, a loose mount, a TIGHT mount and silicone screws...all have this weird vibration noise.
Hmmm.. now we just need to see a 3-fan monster, with a Sharkoon-Delta-Sharkoon sandwich setup :).
How about a Delta-Delta? GFB (76mm counter-rotating) on top of a TFB ;)Quote:

Ahh. You know, you're not the first person to report that about the vibration issue with that fan/mount design... isn't it ironic that a design intended to reduce vibration actually causes it? :clap: (<-- golf clap for the AC engineer for that one... maybe needs to take some more night-classes).Quote:
