How to make a USB Fan

[sickstyseven]

Yup, fan BLOWS

[cookie73942]

You should have connected the led before the switch so you could see when you had power or not.

I do its not workin

[shyb76ers]

@chiefequationP how did you strip those small red and black wires

[dramey03]

i love you you are the man

ive been looking for a simple design for quite a long time, i only find incredibly detailed harvard grad crap lol

thanks for breaking it down simple for us

a cheap computer a usb port expander and you got all the fans you need

youre the man

that fan is spinning slow... usb only puts out 5.25 volts. fan needs the full 12volts to run at full rpm

[blazingsamuri]

@norge696 use a joule theif and a speed controller switch.

Hello. will it be possible to connect another fan and power it using the two remaining wires which were previously cut off???.....

[lendemen95]

how can i make i faster?

[chiefequationP]

I did this for fun, I dont know much about volts. If you dont like it then you dont have to do it. It work for me and still works.

[hanrickjones]

Do u have an idea that the fan ur usin has a 12 volt motor and a normal led is off 3.3 volts I repeat normal

whereas the current in usb cable is off somewhere around 3 i would say max 3 volts

but u still not overeloadin it

on th same hand too you all youtube guys

dont wast ur time doin this at ur home coz thats of no use it will look cool oh ya the fan is movein but that is it nothin more

sorry chief don't take me wrong :)

[thedarkesmaster]

in my usb cable is red black green and white which to use you think

[izhan22]

i am low at these things

please tell can i use this one really without any circuit

will it work without DAMAGING my MOTHERBOARD

i am going to try

this

[sk8boiie559]

how meny volts is da fan?

[sk8wpg]

How long can u keep it running

[bmriches]

Worked perfect thanks! Now fuck your your mother...

[dudedxrox]

@feryxxx that is because a usb can only give about 5 units of power and a computer can give 12.

[CrewOfMasters]

Remove the LED and the fan will run slightly faster, you dont need the extra resistance, and its not like you can't tell whether its running anyway.

[AyashiFX55]

the led and the switch is a waste of time (not saying i dont like ur video) but they create extra resistance. If you try to measure the usb, it roughly produces 4.8V which is extremely slow and can be considered almost as useless at that speed ... Just directly use red / black from usb and direct fan ....

[feryxxx]

the thing is when i plug in an USB with a pc fan, it doesn't spin nearly as fast as in the pc... :(

[DjRazZ93]

it works only with usb cable connected direct to cooler?

[robcollinson190594]

thanks for the advice

[turewarrior0]

what's it for..?

[Atte93]

LED gets too much power and it won't last for long, you can see it at the led is meant to lhave a green light, the LED of yours glows in yellow. And yes, too low RPMs for the fan. And it would be nice to

[Atte93]

make it a bit more complicated, for example make the fan adjustable, you won't need more than 1 part to that. And you can fix that LED power thing with a resistor.

[67tr876]

i did it but am geting 5v to the fan i need 12 volt for full speed but its ok i use it to cool my labtop

[k4milo900]

przecież ten led sie spali ...

that LED will be smashed... because led have 3,2-3,6v but u give that led 5v.

[glitchmaster99]

too low rpm

[grennssleevs]

This overloads the usb fan usb?

[chiefequationP]

No I have had mine running several minutes with no problem.

[isawadeadfrog]

Could it not cause damage over time with the excessive load? I really want to try this idea but using a powered usb hub.

[grennssleevs]

how to connect the light to the fan? Need a transistor?

[chiefequationP]

I used a two prong LED and plug it into a plug that I got from a PC. Then connected the positive and negative wires to the switch.
