40mm fan suggestions

Twill · Post by **Twill** » Tue Sep 14, 2004 6:56 am

before you say it..I know...40mm can't be quiet but still I must try.

I noticed that the silenx 40mm are not to popular, I was considering adda, any other suggestions?

Unfortunately modding for 60mm isn't possible (It's a SFF PSU fan ).

Any suggestions would be greatly appreciated.

Thanks

Is this a fan in a Shuttle box?

I was thinking about taking the 40mm fan out of one I was building and then cutting an 80mm hole in the side of the PSU. Then insert an 80mm Panaflo...

You should have room to do this, no?

The 40mm Sunon Mag Levs are pretty good to me.

Yes it is a shuttle, I would like to avoid cutting it up too much. I will be WCing it at some point and may WC the PSU but in the mean time I am desperate to shut up the fans that are in there.

The sunon 80mm that came with the case didnt impress me, but I will look into it.

Any more for any more?

If you can stand a double-thick 40mm fan, those 40mm x 20mm Sunons are sort of quiet, at 5-7V.

So nothing in a normal thickness that runs in the 15-20db range?

I'm not trying to get my hopes up but would love to find something

Anyone have any experience with silenx or have a reason I should avoid them in particular?

HAHAHAHAHAHA!

No, and even if it measured at a certain dB level, those measurements don't seem to pick up the very annoying whiny hum that 40mm fans generate. I've posted about it several times here at SPCR, but I'm a "mobile rack" freak and have constantly been on the lookout of a 40mm cooling fan that's actually quiet. I've never found one. The 40 x 20mm Sunon is the quietest I've found, but it's still pretty annoying.

The only 40 x 10mm fan that is even close is the ridiculously expensive ($12-15 each) Adda fan that Mouser.com sells. If you search for my posts (something like "adda AND mouser*" by Ralf Hutter) you can probably find the model number of those Addas, if you want to play with them.

I used Adda 40x10mm fans (three of them) fitted into a drive-cooler front-bay panel effort. At 5V they're not *too* offensive, and three fans provided enough airflow to keep the air circulating around my hard-drive.

There's a bewildering array of them though, a la Panaflo, with low, medium and high airflow. I *think* the jobbies I had were the L models, though I did get an M by accident and boy was there ever a difference in noise.

They cost a couple of quid each ISTR.

The fan on SwiftTech MCX159 chipset heatsink is reputedly quiet.

The Silenx fans are Adda's (TTBOMK), so you could purchase them interchangably. (Silenx is a re-brander, not a manufacturer, for most of what they sell)

Silenx's "unpopularity" here at SPCR has more to do with the raving nutcase that runs the place, and not their products per se. *

LoL at rusty.

So the best bet for now is to just go with the adda or silenx fans and spend copious amounts of money on them?

Unfortunately I cant fit the 40x40x20 in the spot...needs to be 10.

If I find anything better, I'll let you all know.

Here's the info on the Mouser.com 40mm Addas.

I have a 40 x 20 Adda rated at 10 dba, I think 4.7 cfm I got it from Mouser. Does not move much, but it was good enough to replace the noisy OTES fan on my ABIT IC7 Max3. It was expensive though cuz it is not a stocked item.

I cannot say for the SilenX 40mm fan, but I have 4 of their 80mm 14 dba fans in my case. They are quieter then any comparable fan I have had (Japanflo and Papst).

OK, so two questions:

How well does the sunon maglev undervolt and does it still get good noise to flow?

What about some 60mm options? anyone have suggestions, I really only need to push 6-7cfm so undervolting a 60mm should be more than enough I'm thinking

Any suggestions are great thanks

The Asaka DFS401012M is rated at 25.6 dBA http://www.akasa.com.tw/spec/fans/spec_ ... 2m_oem.htm. I have one of these fitted to my Radeon 9000 and the sound is Ok particularly undervolted (see http://www.silentpcreview.com/article164-page1.html). There is a similar (identical?) YS-tech one as well, see http://www.kustompcs.co.uk/acatalog/info_2531.html.

And look at the killer airflow! A full 3.5 CFM! lol

Right on though Trip. The Papst 412FM is one of the very few quiet 40mm fans. endpcnoise is a great site too.

I would not recommend Sunon's 40mm MagLevs (or any Sunon for that matter). They're 'whiners' to the core (at least for me they were).
