Best fans now?

[zombie67]

I am running dry of most fans, and it's time to resupply. What are the best fans lately? I'm looking for QUIET and AIRFLOW. Don't care about anything else, including cost or nonsense like LEDs. Three sizes: 120mm, 140mm and 200mm.

http://www.scythe-eu.com/en/products/fans/gentle-typhoon-120-mm.html these are pretty good for 120mms. F$ is the fan guru though so he'll have to verify that :p
If he approves, conversions are as follows:

Technical Data:
500 rpm: 0.015 A - 5 dBA - 31 m³/h (18.25 cfm)
800 rpm: 0.023 A - 9 dBA - 48 m³/h (28.25 cfm)
1,150 rpm: 0.034 A - 16 dBA - 63 m³/h (37.08 cfm)
1,450 rpm: 0.049 A - 21 dBA - 85 m³/h (50.03 cfm)
1,850 rpm: 0.083 A - 28 dBA - 98 m³/h (57.68 cfm)

Actually scratch that. Enermax to the rescue. Both are 120mm

http://www.newegg.com/Product/Product.aspx?Item=N82E16835214001 69.15 cfm @ 18 dBA
http://www.newegg.com/Product/Product.aspx?Item=N82E16835214037 71.25 cfm @ 18 dBA (white LED)

Use the scythes above for heatsinks/radiators and these for case intake/exhaust.

140mm http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007998%20600035592&IsNodeId=1&srchInDesc=xigmatek%20xaf&page=1&bop=And&hisInDesc=xigmatek&PageSize=100
These Xigmateks are the best i've seen as far as cfm vs noise. The next most efficient would be to put the 120mm Enermaxs in your 140mm spots.

90.3 cfm @ <18 dBA

Caution: Aeronautical Oil System bearings aren't cheap

200mm http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007998%20600035599&IsNodeId=1&bop=And&SrchInDesc=apevia&Page=1&PageSize=100
125 cfm @ 20 dBA. Only 1 dBA louder than the Cooler Master 200mm fans, but 15 cfm more airflow. Seems like a fair trade-off to me...

i forget the name but shortly after i built my q9450 rig i upgraded to a turbine type 18? blade unit it did drop my temps 3 degrees. but now that i read up on this typhoon i must have one! lol just give me 3 weeks...

I've always found the best fans to be the Green Bay Packer fans. :D

Me? Guru? Me thinks you have fallen on your head..... :))

JPM makes some great suggestions. With that said I still like the Akasa Viper 140mm fan. If your case(s) can take 140mm fans then I highly recommend the Akasa, but the only eTailer that sells them is FrozenCPU.com

(FrozenCPU Link (http://www.frozencpu.com/products/13819/fan-901/Akasa_140mm_x_25mm_VIPER_PWM_Fan_w_Hydro_Dynamic_B earings_AK-FN063.html))

Akasa Viper 140mm Specs
Dimension: 140 X 140 X 25mm

Cougar 120mm fan. 300,000 hours MTBF. 70.5cfm @ 17.9 dB

Very similar stats cfm vs. noise stats compared to these Enermaxs: http://www.setiusa.us/showthread.php?4144-Best-fans-now&p=48742&viewfull=1#post48742

I really like these:

http://www.newegg.com/Product/Product.aspx?Item=N82E16835226042

Been buying them recently for cpu cooler fans and case fans. 74cfm 15dBA

Nice find! Noise to CFM ratio definitely much better on those.

Best fans are Duke's fans.

@JPM: Question for that COUGAR CF-V12HP fan you listed. In the overview section a graph showing Static Pressure (SP) vs CFM. Am I correct in thinking that graph is wrong? Shouldn't SP rise with airflow rate?

@JPM: Question for that COUGAR CF-V12HP fan you listed. In the overview section a graph showing Static Pressure (SP) vs CFM. Am I correct in thinking that graph is wrong? Shouldn't SP rise with airflow rate?

Nope CFM normally drops as SP rises. Think of higher SP as backpressure which restricts the CFM. The strength of the motor has alot to do with how much SP you generate at a given CFM. On some cheaper fans, when airflow gets restricted by a radiator, heatsink or whatever, this can cause the blades to spin slower which makes the loss of CFM when faced with higher SP significant. Also some people (like me) like to keep positive pressure inside of their cases. This also creates some SP since air is being pushed in faster than it can get out.

OK, I see the problem. I was thinking in terms of SP "potential" in terms of a specific RPM setting (Free Air), not its "measured" CFM rate. Thanks for clearing that up. I guess if the graph had also included current draw or HP it would have been much more apparent.

Best 230mm fans: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007998%20600339700&IsNodeId=1&bop=And&SrchInDesc=pro&Page=1&PageSize=20 other colors are available when they have them

These fans are excellent case fans. This size is typically found on HAF cases (such as the front air intake on the HAF X and HAF 932) and others. These fans provide ~50% more CFM than Cooler Master's stock fans. Recommended for intake only. Exhaust should be lower CFM than intake to keep dust out and to cool more efficiently (positive pressure).

Verified. 25% OC'd Intel 6850 with OC'd NVidia GPU runs cooler with the replacement than the original in my case which died iin under 1.5 years.
