if I stacked two USB cables like this, what measure of V would the fan be receiving?

here's a sketch of it,

Whatever the adapter allows
Jordan Long
Power sources in series increase voltage
Power sources in parallel increase amperage
They are in parallel so no voltage increase
Bentley James
What he said.
Thomas Mitchell
It is a parallel circuit; therefore the voltage is +5v and the current is the sum of the adapter currents.
Noah Nguyen
your problem is that the USB voltage is 5V but the fan is designed for 12V.
Just buy a wall wart that outputs 12V, there are tons of those out there for cheap
Brandon Thompson
The circuit would be in parallel, so it wouldn't increase the voltage. It would increase the current/amperage.
Ethan Gomez
look at us all, science anons helping someone out.
Joseph Moore
More along the lines of pointing out stupidity
Sebastian Young
It also depends a lot on if the power supplies are isolated or not. Really cheap USB power supplies generally aren't so even if you do put them in series, you'll just blow one of them up as they'll be sharing a common ground.

You will electrocute yourself
Elijah Lee
this nigga knows his voltages and shit!
Jose Davis
google probably would've worked but most people do not even know the vocabulary let alone the specifics.
Carson Rogers
What if he stuck a capacitor in there? Could that make it 12v?
Josiah Collins
No lol
Samuel Smith
what if he stuck a flux capacitor in there? coud that make it to 88mph?
Jonathan Johnson
only if the positive pin of the capacitor is stuck in the pee-hole
must be at least 47 uF, voltage rating 16V (for the ripples)
Liam Gonzalez
dont do this youll be sorry
Blake Turner
Yes
Kevin Watson
Yes but you need a couple more components too.
Cooper Clark
Inductors are very fun
Thomas James
I prefer 8 AA batteries in series :D
Alexander Smith
I too are masochistic enough to like changing batteries every 5 minutes

Simplest is buy a "wall wart", or plug in power supply as most call them, and output +12v. You can however make a "boost" circuit or use a boost IC to make up the voltage. The cost however is going to be a lot more than a wall wart or transformer and rectifier.
Also, your PC have 12v inside. Use that. If however you're using a small USB wall charger the you're fucked. Go by an LED power supply for $2 on eBay.

Is this a DigiKey thread?

>hipsters trying to into wiring diagram
instead of drawing the fucking fan out like its art class, try [M]
