Need a powerful fan

[Faisal A]

Hi, I am doing an electronics project and need the highest rpm and highest CFM fan I can get. Something like the blowimatron (linustechtips video : 7x your cooling) but it needs to be cheap. I do not care about noise.

delta 1u server fans? i think they have 23k rpm's or something stupid like that

@LukeSavenije Thanks

DC Fans : https://www.digikey.com/products/en/fans-thermal-management/dc-brushless-fans-bldc/217

AC Fans : https://www.digikey.com/products/en/fans-thermal-management/ac-fans/216

 

Filter by voltage you can use (you can run fans at lower voltage, so for example if you have 18v power supply for your project, you may use 24v fans but they'll run at lower speed)

Then filter by CFM or pressure, depending what you need cooled (you need pressure for going through tightly finned radiators, and high cfm is better for just moving lots of air ex through extruded aluminum heatsinks)

 

Here's a filtered list: 12v only, in stock, sorted by CFM : https://www.digikey.com/short/prt48h

42$ 120m x 38mm 7400rpm 254 CFM ~44w  : https://www.digikey.com/product-detail/en/delta-electronics/PFR1212DHE-F00/603-1701-ND/3078055

30$ 120mm x 38mm 6000rpm 250CFM (4wire, with PWM) : https://www.digikey.com/product-detail/en/orion-fans/OD1238-12HBXJ10A/1053-1614-ND/5230572

 

example of high pressure fan:

 

36$ 80mm x 38mm 16300 rpm 130CFM pressure : 4.969 in H2O (1237.8 Pa) : https://www.digikey.com/product-detail/en/delta-electronics/PFM0812HE-01BFY/603-2045-ND/6580735

 

You can sort by price and then pick the best price vs CFM ratio fan that meets your needs... you may not need the top of the line highest CFM fan available.

Also, the same fan may be available in different versions... with only 2 wires (voltage and ground) or 2 wire (+rpm or seize/stop alarm) or 4 wire (pwm) ... you can connect the pwm wire to a motherboard or a fan controller, but careful about powering such big fan from motherboards... most don't do more than 1-1.5A sustained through a fan header. I wouldn't do more than 1A through a motherboard fan header.

i added an example of high pressure fan in my previous comment... 16300 rpm delta model, 52w monster for 36 dollaroos.

@mariushm Thanks. I am making a soldering fume extractor but the extractor is going to end up taking more power then the iron

[mariushm]

Be careful about how much air flow you use, because you don't want to make it so fast it sucks screws and parts from the desk

A fume extractor has to be relatively close to the soldering iron tip to pull the fumes through the carbon filter or whatever you're gonna use, so imagine a person holding a 0805 resistor in tweezers trying to solder it to a board and your big fan sucks the part off the tweezers.

 

[Faisal A]

@mariushm I am going to use a pwm controller connected to a large capacitor connected to the input (+12v and GND) of the fan to adjust the power to the fan. I normally keep my fume extractor 1 meter away from the iron so my current one is useless. Also, I am going to put two fans and a splitter in a 3D printed enclosure to suck the smoke from my laser cutter so I might need that extra power, Generally, I use through hole components as they are easier to solder and I am not that good with the hot air gun

Excuse me to introduce you this new EK-Meltemi 120ER, an EK newly released 120x38 1800 RPM fan,

[RejZoR]

Well, Delta is always the answer if you want fast fans.

 

If you're looking for consumer products, look at Enermax TwisterStorm 12mm. 3500 RPM monstrosity. 260m3/h and static pressure of 11mm H2O It's actually not that loud at 38dB...

@PotatoCanDo!

 

And what's so special about it?

 

Besides being low rpm, it has just average pressure and air flow.  I guess it could be SILENT for the amount of pressure it does.

 

Yours is 37$ for some crappy specs... 62 CFM and 2.75mm H20 44dBa

 

Even this 14$ model has better specs : 

 

AUB1212H-CK15 Delta Electronics - 120mm L x 120mm H 25.40mm 88.6 CFM (2.48m³/min) 0.161 in H2O (40.2 Pa) (4mm H20) 2200 rpm  3.24w 38dBa

 

Here's beefier alternatives.

 

43$ 9GA1212P4G0011 Sanyo Denki America Inc. , 120mmx25.4mm , 134.3 CFM (3.76m³/min) , 1.470 in H2O (366.2 Pa) , ~ 2000rpm - 6400rpm

 

Lower power version (max 5400rpm, 7w version) is also available: https://www.digikey.com/product-detail/en/sanyo-denki-america-inc/9GA1212P4S001/1688-1865-ND/7102192

 

If you want to match the noise, at 44dBA you have this at 23$:

AFB1212HHE-TP02 Delta Electronics - 120.1 CFM (3.36m³/min), 0.354 in H2O (88.2 Pa) (9mm H2O) , 2900rpm , 4.8w , 44 dBA , 120mm x 38mm

 

You have another model that's cheaper at 19$ but with max 3400rpm and a tad noiser at 46dB: https://www.digikey.com/product-detail/en/delta-electronics/AFC1212D-F00/603-1168-ND/1850537

Lol

That's alot! Nice..

 

I just stumbeled upon that EK fan randomly, so I think I can share it to add more informations.
