Most powerful fan at 140nm?

I want to buy an AC adapter (like this: http://www.amazon.com/110v-Power-Su...hbuuTDL&dpSrc=sims&preST=_AC_UL160_SR160,160_ ) with some powerful fans. I am looking for 140mm, but I could live with 120mm if I have to.

So far options seem bleak. By far my best options so far is downgrading to 120mm, but it would give me 240 cfm @2.5 amps: http://www.newegg.com/Product/Product.aspx?Item=N82E16835213001

Other then a high cfm fan (over 130 cfm) my only requirements is that it needs to be square so I can easily stack them on top of each other.

Any suggestions?
 
This is not for a PC, its for my window. I just want to pump some air in my room. Noise is not an issue unless its not high pitched or something.

I live in an apartment with no control of the heat, so I often have to turn on my 12000 BTU AC to counter the heater. Id rather use fans for a more 'green' solution. I figure with PC fans I can build it exactly to the dimensions and specs I want.

You can get a 2,500 CFM 3-speed box fan from Home Depot for under $20. Any solution based on PC fans will be uneconomical because you really will need 500+ CFM to have an impact on an apartment which is over 5,000 cubic feet (I assume a 650 sq ft apartment with 8 ft ceilings. Check for box fan models which come with window fittings.

I kinda have the same issue. But i'm in a basement and dont have real windows just little ones built around glass blocks. Ive tired your computer fan idea and well it doesn't work. I just bought 2 normal house fans and just leave them on almost always to help circulate. It works on moving the inside air around but nothing to push or pull the air out of the room.
 
use many many quieter fans instead of several powerful ones.

Example.. u have a delta... has 220CFM... @ almost 50+dB.
Your better off stacking 3 x 100 CFM fans @ 35dB.

You can stack them with zipties as well.
Basically zip tie the corner mounts of each fan to each other.

This is a far better solution as you have a greater area in which the fans are pulling, with overall more CFM @ less noise.

The only problem, a stack of 3 fans is larger then a single delta, however the noise difference is almost as great as the sky vs the ground.
 
I will go take a look at my options on Tuesday, but part of the reason why I am looking at computer fans is because I only have about 5.5" of space in my window.

I would get a larger fan and create a baffle out of cardboard or election signs. Even a ton of PC fans will only move a tiny fraction of what you need to even bother.
 
I didn't realize they made 140 nm fans yet. Great for cooling all those 14nm transistors!

. . .

sorry, couldn't resist.
 
An electric fan for a car radiator mightl fit the bill. Those are 12v and high powered.
I pulled a 90mm fan out of a honda and used it for my case in the past. sizes go up from there.

Maybe these Noctua NF-A14 industrialPPC-3000 PWM, but I guess they would run at full speed all the time and would be loud.

If you look at the specs, they're PWM fans with 4-pin connectors. The minimum speed is 800 rpm, max 3000 rpm. The stats are good too: 41.3 dBA, 158 cfm, and 10.52 mm H2O static pressure. And they are only 25mm thick! Which means you could put 3 of them on something like an nh-d15.

Compare that to an Ultra Kaze 3000 rpm which only moves 131 cfm and has a static pressure of 8.22 mm H2O while putting out 45.9 dBA of noise. More than twice as loud with less static pressure and less airflow. It's 38mm thick, meaning you can't use it in some situations where you can use the Noctua fan.

In all fairness to Scythe, their old GT line compared more favorably, but since Scythe is no longer partnering with Nidec Servo, those fans are not exactly available. And they aren't 140mm so . . . blah.

Anyway those Noctua fans look great.

Talk about thorough.

The EK Vardar's look really good as well. It seems like the recall is over, so hopefully more reviews will start to come out soon.
 
I must add an adendum: the Noctua A14 fans do not have 120mm bolt/screw alignment, so they won't fit most HSFs. Blah. They will work just fine on 280mm/420mm rads though.

I don't know much about the EK Vardars other than the fact that they are pretty new. But they're worth a look.

The 120mm Vardar's are very nice fans, comparable to the Nidec Gentle Typhoons. The 140mm ones just started coming out late summer but got recalled.
