i looked on pricewatch and i cant seem to find any 14 cm fans.

are there any? and can they start and run reliably at 5 volts?

also are there any 12cm fans that can start and run with 5 volts?

I have my Delta WFB1212M's running at 5 volt at times. Only thing is a slight ticking noise.

Yate loon makes some 140x25 mm ones. I haven't seen them anywhere, although I'd be much more interested in their 120x38 fans. I'm sure Papst makes a bunch of different 140's.

Many yate loons start below that, under 4 volts.

seasonic claims all else equal, 12cm is better than 80cm, for airflow and noise. in fact 12cm is better than 2 80cm fans.

all else equal, wouldn't 14cm be superior to 12cm in terms of airflow and noise?

How about a 40cm fan and mount it on the side panel?

What? Oh... yeah. OK. Sorry 'bout that.

Back to the real discussion here.

Here in Winnipeg there is a car part and tool dealer called Princess Auto and in their surplus department the had some Papst 6424 140x50mm fans for about $30CAN.
They're 24V, but I run them at less than 12. Since it's a 26 watt fan I wired up two fan controllers in parallel. It runs very quiet and is at least as good as my 120v Accuflow 120mm fan.
But the thing is so big I had to drill new holes in the back, cut away some of the sheet metal, and hang it on the outside of my case. I'm also going to have to go to Wall Mart to find something like a bbq grill to cut down for a finger guard.

You might be able to order some from the above site. The 120v 120mm Accuflow (also pretty good if you have an ac fan control knod wired in) is also available there.

perhaps i'm wrong but i'm sort of the opinion that pretty much any fan, esp 12 or 14cm running at 5volts would be "dead silent"

I think you are wrong indeed.

The airflow noise will probably be "dead silent", but not all fan motors are equal. The volume of the clicking sound some fans make is not always related to the speed that they run.

On top of that higher speed fans usually have a higher minimum speed.

Yep, you're wrong. I think you'd be surprised how noisy many 120mm fans can be at 5V, unless your definition of "dead silent" is waay different than that of most here at SPCR.

Hi all !

Try to contact Yate Loon : www.yateloon.com

The D14SL-12 seems to be the perfect candidate for silence and awesome airflow, although I doubt it will be as deadly silent as a 80mm fan at 5V...

This 140mm fan of Yate Loon spins at 1000RPM, and is a sleeve bearing one. Unfortunately, they don't say what type of connection it has (3-pin, or 4-pin connection ?)....

See you
