It's the DC board making the whine. If it were the processor, then people that own the iMac or Mac mini would be complaining about it too.

The trick with the kext worked fine on 10.4.6, but I did it with 10.4.7 (you're meant to download the 2.4 version, not the 2.5) and my built in isight stopped working, so it's a no…

No such whine from my machine. If you're convinced its a pin on the processor, then no amount of software will fix it. Send it in for a motherboard swap.

dialo is right. There are two types of whines. The inverter whine depends on the screen brightness setting. If your whine doesn't, it's the CPU whine. The CPU whine starts when the…

Yeah, I think you're right. I don't recall having heard reports of the inverter whine on a MB sans pro.

It's the Power Supply that causes the whine. It all depends on how much power is going through it. I've heard whines and similar sounds on PCs, Desktop Macs and Laptops...all relat…

Quote: Originally Posted by Simon I concur. The CPU whine has to do with the processor entering a certain operation state. I'm pretty certain a vibrating lead isn't the cause. I…

There has been several reports about similar whine in other brands as well...

I see something of merit here, though I still don't think it's a lead. I think tt's the whole CPU that's vibrating, albeit in very small increments. Just like switching power sup…
