GTX 480 fan wiring "schematics"

I am really curious to see how loud the GTX 480's fan is in person, but I have no way of testing it. So I butchered one of my 12v fan adapters and took off the shroud. But now I have no idea which wire is which on my 480. So... Any pictures that you can find would be really helpful, or if you can describe the wires well. I wasn't able to find any pictures or descriptions, but I'm in a rush right now to get my homework done anyway.

Aren't they color coded? Pictures would help since they are different from brand to brand..

 

Usually the red wire is (+) and the black is (-). On pwm fans theres a third color for the modulation usually yellow.. i think? It varies dude...

Nope. All black.

I just know a lot about certain things. With all black wires though, things are tough.

 

Look for a 480 teardown vid and look at the fan wires in the vid and match yours to them

That would do no good since I think they're all black wires on pretty much every reference 480 out there.

ssshhhhh, bad boy.

Not a problem mate... in that case what you have to do is commonly reffered to ''trial and error'' lol. But in all seriousness just try until the fan spins in the right direction.... had to do the same thing with my darn corsair case fan ( also all black wiring)

trial and error seems to be the only thing you can do 

I'm just really paranoid about killing the fan.

shouldn't be possible... either it spins or it don't. Just maybe don't touch the two powered wires together :P

Chances are

 

It spins correct

It spins backwards

It doesnt spin at all. At least that would be my thought.

are they PWM bae? then you only have to slightly worry about applying too much to the modulation wire. its trial and error, if you mix + and 0 youll be fine. if you put it on PWM, it just wont spin

I touched them together. :D Power brick just made a high pitched sound. All good. That fucker is loud at 12v, holy balls.

It spun really fast. ;)

 

Thanks for making me get the balls to wing it.

Well, most electric motors with 3 wires have the possibility of forward/backwards/nospin at least to my knowledge. Was it loud?

Yes, and the airflow was godly. Time for a high airflow bracket from EVGA.

Lol I just want to be able to stick two 120mm noctua 3000rpm fans into a card.

Actually no. It wont spint backwards when you reverse the power applied. Brushless DC motors dont do that. It will either do nothing or it will fry. The latter usually happens.

If you apply power to the RPM sense pin watch out for the magic smoke. I've tried it before. The fan was fine but the sensor was toast.

That...doesn't make any sense because it's DC, Direct current, so it should spin backwards

Only brushed DC motors do that. Brushless DC motors (found in most things nowadays) wont do that except if it has additional circuitry that will make it go backwards. But generally, apply reverse voltage and it fries
