In my G5, the one that cools the cards.

I was replacing it after having rmoved several components (the machine was on), saw smoke.

The fan now smells of burnt silicon and refuses to run at anything other than full speed.

I replaced it with a quieter fan, destroying two of those black rubber things on the mount in the process.

How did this happen?

Would there be any way to get a replacement fan?
 
if it smoked you need to call into tech support and talk to them or you can take to a local service provider and have them put the proper fan back in
 
Boooring.

Wouldn't that cost money? I am very well capable of installing the item myself and really would not feel comfortable having some brutish service guy fondling the insides of my box.

Would Apple just give the fan to me? I'm certain my warranty is void. What would a replacement cost?
 
Why the hell did you tinker with it ON :rolleyes:

Not a good idea, if you haven't learned that already.
 
that is a good question (both cost and warranty) as far as the warranty goes the entire thing would not be void..just the fans and mounting brackets but I would have to check to see if they are a customer installable part (I think they are) but I would still recomend calling in
 
>Why the hell did you tinker with it ON

Well, I really wasn't expecting a fan to short. It's never happened before.
That bastard is so difficult to install.

>Not a good idea

Well, this isn't discouraging.
 
Although I'm not an electrician, I know to NEVER mess with something electrical with juice still going through it.
 
yeah that's right, tell Darwin hi when you see him, sounds like you're up for one of his awards
 
It's still going to start pulling power all of a sudden when it WASN'T a moment before. Not only can it do this only partially connected (which can pull the wrong current and damage componants as well as the fan), but it can do things to the circut board you're connecting it too as well, since power will suddenly flow where none was before. Undervolting / overvolting things is bad.

You never, EVER, connect something with the system running. EVER. Those electronics are VERY sensitive, and that's a fast way to need a mobo replacement.

Yes, it's a fan, a fan on a Computer that costs thousands.

Don't connect things while it's running. Hopefully you got away with a dead fan... you could have killed something else. Learn from this...

I AM a cs major, and I HAVE taken EE classes. Don't do it again.

Yes, I have experience in electrical engineering.

Well, yes, but the system expects the fan to be in place, so this section recieves current at all times. If I had shorted something on the motherboard, what's the worst it could be?

The fan was very difficult to install, and I apparently connected the wrong pins first.

>Don't do it again.

LALALAALA!!! I CAN"T HEAR YOU!

I always work with electronics while they're powered on. How else will I know the hack was succesful? Besides, you can't measure voltages on a dead system.
Boot sequences take too long, and this is much more convenient for me.
 
>is that electrical engineering or "rigging"?

Is there a difference? You don't learn about EE by reading a bunch of text books.
 
Shut off your computer before you go fucking with it
eek, your making my kernel all panicky
 
I was joking, chill, I know there's a difference, there's also a huge difference between an EE and an Electrician, an EE can know all kinds of theory but know squat about application.

You could kill the motherboard.

It's your funeral, dude. Even the earliest pioneers weren't that stupid. You do not work on live electronics, it's the first rule of electricians and engineers both. But, if you want to play russian roulette with juice, be my guest.

Oh, and how do you do it properly? You turn it off, do your work, and then turn it back on. You take the time to:
a. Not kill your system.
b. Not kill parts (what you did).
c. Not kill yourself.

Are a few seconds worth the hundreds of dollars a G5 mobo costs?
 
Im locking this thread out of sympathy.

On a related note, when got my playstation 1 (it was almost brand new) i took it apart and watched it work with the power on. It was fascinating. Then I dropped the screwdriver on the main board. Fuck me. I never heard the end of this and it was a mistake telling my friends about it.

*cough cough* forgot to lock the thread. rectified now. :D
