Quiet 140mm Fans?

Any suggestions in the 140mm size?

Scythe Kaze Maru 500rpm is quiet enough for me.

Thanks, I'll check it out.

Kaze-maru is 140mm fan with 120mm holes. If you need true 140mm silent case fan, I recomend Yate-Loon DS14L-12

He means D14SL-12...

Indeed, I accidently pressed both D and S at the same press and did not noticed.

Yes, being the worst typist on the planet, I figured something like that happened

Just as a FYI, the D14SL-12 will develop bearing noise when mounted horizontally. It is a 140mm fan with the motor hub of a 120mm fan, and as such the bearing is not up to the additional load of the larger blades.

Hi,

I have to admit that I have not found this to be a problem.

For the same airflow, the 120mm fan has to run at about 40% higher rpm. Bearing load is proportional to the square of the rpm, so the 140mm fan running at lower speed should be fine despite teh greater mass of it's fan blades.

I had a Thermaltake PSU for a while that had a Yate Loon D14S-M12 I think it was, mounted horizontally, and the bearing noise from it was hideous.

Hi,

The M12 was probaly a fan rated at 1500 rpm @ 12V.

If it was running at anything like that speed I can well believe it became noisy.

You should not need to run a 140mm fan at above 800 rpm to keep a reasonable PSU cool. I have a Seasonic S-12 430W which I have modified by fitting a 140mm fan. At 250W power load and the fan running at 800rpm the output temperature of the PSU is only 2C higher than the input temperature.

I could tell from both the tone it produced, and the frequency of the ticking / hissing that it was running at about 1000rpm at idle (high, but even so, the noise was terrible). Believe it or not, when it reached beyond 1300rpm or so the noise seemed to disappear and it became smoother.

How does the Scythe Kaze Maru go against a 120mm slipstream for quiet/airflow ? Id guess it should be better assuming the bearings are up to it

I don't doubt what you say, but I can only report my own experinece:

I have used about 100 a Yate Loon 140mm fans, specifed by me and desgnated as D14SM-12 by Yate Loon, on CPU coolers and on PSUs, and for Case Ventialtion, with fan speeds between 350rpm and 950rpm. In all cases there is no perceptable bearing noise and only very slight airflow noise at the higher speeds.

I think you got a fan with damaged bearings.

Usually case fans are sleeve bearing from YL while PSU's use Ballbearings, which are a lot more louder in terms of bearing noise. It would be nice to know exact type of YL's bearings though. You really cannot go compeare sleeve bearing YL's to Ball Bearing ones.

My 140mm 1000 RPM YL @ 12v (sleeve bearing D14SL-12 ) has same noise charasterics as Nexus 120mm fan which is excellent, dark and without percivable bearing noise, even when horizontally mounted.

samuelmorris · Post by **samuelmorris** » Sat Feb 21, 2009 2:08 am

The noise it made definitely suggested sleevebearing, and I'm pretty sure HardwareSecrets' report on it said it was a sleeve, which is why it was surprising, as Ball bearing fans are more suitable for a PSU, but in my experience tend to be slightly more abrasive in the noise they produce.

I agree , ball bearings develop more abrasive noise , sleeve bearings are generally speaking more silent , the problem of sleeve bearings when installed horizontally is that sometimes ( not always ) some washers attached to the axle start to rub against each other or againgst the plastic of the internal frame around the axle and this can produce noise

samuelmorris · Post by **samuelmorris** » Tue Mar 24, 2009 4:00 am

In my experience they tend to start doing that regardless when they get old. However, I haven't had any fail completely yet, whereas I've had at least three ball bearing fans fail, in one case it started billowing smoke! (Silverstone FM121, c. 9 months age)

Yes, having bought a more suitable case for my Dual 4870X2s, the Coolermaster HAF, I have a rear 140mm fan slot, and the stock coolermaster one is bunk. It's quiet enough, but pushes as much air as an 80mm probably would at a reasonable noise level. Was looking at Aerocool Streamliners (more specifically the White Lightning) on the back of how impressed I've been with them in my friend's Watercooled system (they're his rad fans). Either that, the Sharkoon black fans at Scan, or the Xigmatek ones. Anybody tested any of these?

(Don't laugh at the X2s and HAF, at idle the only thing I can hear is the 1600Hz whine from my HD753LJ! )

I am also considering the Aerocool Streamliners White Lightning. Please post how quiet you found them.

Unfortunately I decided to go cheap and get a Sharkoon black fan as I bought this lot from Scan, who don't sell the Aerocool fans. However, having heard the Aerocool fans in a system I still say they're worthy of consideration for people who want quiet 140mm fans with LEDs.
The Sharkoon I bought performs admirably, is quiet at idle (though its difficult to hear anything over my gaming PC's HD753LJ) and can be noisy (the 1500rpm version) but very powerful at full speed.

Thank samuelmorris.

I have found an Akasa AK-195BL a 140mm fan which I find no mention of of here. http://www.akasa.co.uk/akasa_english/sp ... 195_bl.htm

It has ok specs, no LED, and is made of questionable plastic colour.

tonschk · Post by **tonschk** » Tue May 26, 2009 10:00 am

To be honest , I dont like LED fans , I preffer the full Black matt fans to avoid colour coordination problems inside the case ( the colors of the NOCTUA fans are horrible ) , the LED increase a lot the wattage consumed by the fan and therefore add unnecessary heat to the airflow that go through the fan ,increasing the temperature of the airflow , therefore LED fans are not for me

samuelmorris · Post by **samuelmorris** » Tue May 26, 2009 8:15 pm

Having a light source in the case isn't to everyone's taste, but the heat argument is crazy. The LEDs in a fan only use a maximum of 0.4-0.5W, and because LEDs are very efficient, you're looking at perhaps 0.1W of heat at best. The motor in a fan produces much more heat than LEDs do.

Yes I agree the difference in watts between the fan with LED and without LED is not huge ( 0.96W vs 1.68W ) , but I want to reach the minimum possible temperature in my computer , therefore I need to eliminate all the unnecessary heat

For LEDs, the vast majority of that power draw is turned into light, not heat. As said before, they are really efficient. THe difference will have no measurable affect on temperature, especially if the fan is exhaust so the extra 1/10 watt is venting out the back.

swivelguy2 · Post by **swivelguy2** » Sat Jun 13, 2009 11:07 am

Most of it is turned into light, but once that light hits some surface inside the case, it ends up as heat too.

However, I agree that half a watt of LED power isn't going to change anything. You could also maybe find a way to clip the LED leads and disable it without affecting the fan.

I've tried the Aerocool offerings and found them to be obtrusively bright and not perform well with any resitriction. They are actually a thinner fan (20mm), and since there is a large amount of space between the edge of the blades and the inside of the frame, the fans exhibited a noticeable amount of "blowback" when mounted behind any type of grill or restriction.

So, after being unsatisfied with the Yate Loon and Aerocool options, I have since been using the Scythe Kaze-Maru 140mm 1200RPM version and have had zero issues with them. Undervolted to about 800RPM or less they perform flawlessly, and they're reasonably cheap from Newegg. The design of the hub supports makes them almost perpendicular to the blades, helping to keep them quiet. I don't understand the logic behind people writing these fans off because they are a "fake" 140mm design. The fan blades ARE larger and longer than many 120mm fans, despite the position of the mounting holes (notice how much closer the mounting holes are to the fan blades?).

The problem arises when you need 140mm fan for 140mm place that has screw holes only for 140mm fans, like Antec Three Hundred's top. It can be mounted but with some tinkering. I wish Kaze-Maru's would be supplied with 120mm and 140mm screw holes...

so do I. There still arn't any properly good fans that come with proper 140mm mounts. The soon to be release noctua 140mm has 120mm mounts as well.
