cooler master or yate loon
I have heard a lot about yate loon low speed fans being very quiet when undervolted and they are very cheap (like $4) also these cooler master fans seem like they would be very quiet when undervolted and both have a great price I will be using three or four of them in a micro atx case with insulation on all sides one fan will go on the power supply one on the back of the case one on the side panel for CPU cooler and possibly one on the bottom of the case I will be connecting all of them to molex connectors so I can only get 12, 5, and 7 volts my question is which fans are the best value and are they quiet.

Hi,
You can't go by specifications -- the CoolMaster fans I've tried are clicky and rough sounding. The Yate Loons are quieter, but they are not the quietest you can get. The low speed Yate Loons are the best of that line, but the Nexus (made by Yate Loon) is much better.
I'd recommend the Scythe Slipstream 800 or 1200RPM. Or, the GlobalWin NCB, and others have used the Scythe S-Flex; though these are expensive.

You don't know what the difference is do you. I buy my fans direct from Yate Loon, and I have to spec what I want anyway - every fan they manufacture is made to order - so if I could specify whatever they do for Nexus.NeilBlanchard wrote: The low speed Yate Loons are the best of that line, but the Nexus (made by Yate Loon) is much better.

I have to say that once you are into 120mm or (preferably) 140mm fans running at speeds between 350rpm and 950rpm they are all pretty quiet, and the arguement for buying on price becomes stronger.
I'd be worried by a 1200rpm fan whoever manufactured it.

Well, Neil recommended a 1200rpm Slipstream because at 800rpm SPCR found it quieter than the stock 800rpm version. It undervolts very well, which I can personally attest to.
The Nexus fan are (I believe) cherry picked to be smoother/quieter/less clicky and also have been modified to run at 1000rpms @ 12v instead of the Y/L's 1350rpm.

Hi,
If you are right about this it provides evidence that sample variation is indeed significant.
We know that's the case with Yate Loon Fans (they told me).
I'm struggling to think of any reason why a 1200rpm fans running at 600 rpm at 6V would in fact behave any differently than an essentially identical fan (just fewer windings) also running at 600 rpm but at 12V.
Peter
I'd expect to find that the two fans were essentially identical, with the lower rpm variant simply having fewer windings per coil. If I'm right it's possible that SPCR findings are the result of sample variance, or maybe the 1200rpm Slipstreams are in fact "cherry picked" as the effects will be more signifcant at higher rpm.jhhoffma wrote:Well, Neil recommended a 1200rpm Slipstream because at 800rpm SPCR found it quieter than the stock 800rpm version.
That makes sense, and wouldn't cost that much to do, whereas actually manufacturing a different fan...The Nexus fan are (I believe) cherry picked to be smoother/quieter/less clicky

I think "modifed" is a strong word if the design is the same and all they do is change the number of windings per coil.and also have been modified to run at 1000rpms @ 12v instead of the Y/L's 1350rpm.

Hi,
There are also differences in the shape and angles of the blades of the Yate Loon branded models, and the Nexus. And there may be differences in the angle the struts are in relation to the trailing edges of the blades.
Personally, I like the 800RPM Slipstreams better than the 1200, because they are decent at 12v, but any louder is too much for me. So if I never use them at full speed, why bother getting the faster model?
As for bearings wearing out, I have only ever had a Yate Loon medium speed (replaced by a GlobalWin NCB) in an old Fortron Source PSU start to get noisy. And a could of old NMB 80mm fans, that got replaced by some Enermax Enlobal models.
IIANM, that Fortron Source PSU is THE place that the Yate Loon fans were "discovered" hear on SPCR? (By someone else -- I got it because it was so quiet.) They were very hard to find on the retail market, for what seemed like an eternity, and then Nexus came out with their fan, and both the low and the medium speed YL became fairly common place, though NewEgg never carried them, IIRC.
This was back about 5 years ago (or was it seven?) when cases with 120 fans were as rare as hen's teeth...

Hi,
That has to be the way to go.
While some fans are better than others, the differences pale into insignificance compared with the improvements from simply using larger (or more - total cross-sectional area is what counts) fans at lower rpm for the same airflow.

Hi Neil,
The actual cost of making the fan is all in the tooling for the blades and case/struts, plus winding the coils.
If the actual design of the Nexus is better, and the fans are made by Yate Loon, then why wouldn't Yate Loon use the improved design for all their fans.
On the other hand, if the Nexus is better because of cherry-picking, and the design differences are there as only as branding, then I'd find this easier to understand.

I find that extremely interesting, and a bit surprising.NeilBlanchard wrote:There are also differences in the shape and angles of the blades of the Yate Loon branded models, and the Nexus. And there may be differences in the angle the struts are in relation to the trailing edges of the blades....

I've a Coolermaster PL12S12L 120mm rated for 1200rpm/12v. On a Ninja, the Coolermaster @6v is more quiet than the YL D12SL-12 @5v. Not sure whether these PL (powerlogic?) fans are still available.
Do note Coolermaster orders fans from a variety of manufactuers. The CM fans you linked to appear to be from a different manufacturer, as model number starts with DF.

Hi,
And here are a couple of variations of the Nexus:
And from the "Anatomy of the Silent Fan" article, here a related graphic:
The struts on the (later?) Nexus models are rounded and smaller (at least the 3 are), and now that I see them again, the blades are pretty similar. I may be remembering the medium speed Yate Loon?
Following up on this, here's pictures of the Yate Loon (low speed) fan:NeilBlanchard wrote:There are also differences in the shape and angles of the blades of the Yate Loon branded models, and the Nexus.
