PS3 FAT component identification

Hello guys.
Just took apart my nephews PS3 as it was over heating - The fan is not running at all and so took a quick look. There is a component burnt out on the motherboard. I suspect a resistor but have searched on line the last few hours and can not find anything about this component. Anyone have any idea where I'd be able to identify this component?
I attach a photograph (I hope it attaches) to see if anyone can shed any light.
Cheers,
Graeme

Hello Foster.
Wow - quick reply. Yes when "blown up" (quite literally) this is looking ilke a capacitor as per your pictures. Just trying to figure out a value for it. I've metered out the fan and there are no shorts and the fan is very free rotating and so not sure why this capacitor has burned up. I was going to replace it and just try again to see what happens. If it burns up again then I'll most likely go down the route of making a controller for the fan. But first it's getting the capacitor value. I've attached a larger photo if anyone out ther has any ideas.
Thanks again - Graeme

Just found a link to a "leaked PS3 service manual" so downloading that and hopefully it will have some information in there. If not I'll just make a modulator and external fan controller.

Ok, so I now have the full circuit diagrams for the PS3 and have almost identified the component that has failed. I have the full parts list for all capacitors, resistors, IC's etc but what the heck is an FB???
Some kind of fuseable protection??
Anyway - I attach a section of the circuit diagram in case anyone has any ideas.
Cheers, G

Ok, so now I have found the part and have just ordered a hand full of these components. At only 4 pence per unit I think the Nephew will be pleased that it may fix the dead fan in his PS3. Or at least get me a little further into fixing the thing.
Cheers, G.

I'm glad you find the component dude :p 4 pence you can't go wrong

Ok, so an update. Ordered and received the ferrite bead from Farnell Electronics (decided on an uprated 2.5Amp ferrite bead) and fitted that earlier today. Can confirm the unit is up and running like new again. Been powered up 5 hours and then under heavy test for > 8 hours - no issues. So my nephew now has a spare PS3 if his "slim" ever breaks. Simples....
Think I might start trawling e-bay for faulty units and start repairing them in my spare time.
