Quiet 140mm Fans?
Any suggestions in the 140mm size?

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.

Hi,
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.

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

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.

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 noisesamuelmorris wrote:
Ball bearing fans are more suitable for a PSU, but in my experience tend to be slightly more abrasive in the noise they produce.

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.samuelmorris wrote: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.

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.

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

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 heatsamuelmorris wrote: but the heat argument is crazy

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...silence wrote:I don't understand the logic behind people writing these fans off because they are a "fake" 140mm design.

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.thejamppa wrote: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.
