Fan problem on Galaxy 9600

Hi,

My graphics card has been fine for the first few months, but know its started this terrible wirring noise. I can't find my receipt anywhere to get it replaced, so I may be forced with having to fix it my self before it completly packs in.

I did try peeling back the sticker in the middle of the fan, in the hope that there would be a plug to remove and then drop some suitable oil in, but no luck. I can't see how to lubricate this fan from the front.

The card is the Galaxy GeForce 9600 GT 512MB DDR3, low profile to fit into a slim case.

The fan is sealed behind the plastic enclosure of the entire heat sink assembly, I'd have to completely take the hole thing apart. It also looks like the copper plate is bonded with sticky pads to all the chips underneath.

I've never done this before, so I'm worried about pulling to hard on the copper plate and breaking something, what if they've used glue to bond it to the card ? and I don't even know if I'll be able to find where to put the oil into the fan!

Any help is appreciated.

Thanks

Thanks for the help.

When you say 'cowling', which part do you mean?

There is no plastic cage for the fan, its only protection is the plastic shield for the whole assembly (including heat sink). There seems to be good clearance with this.

It heat sink assembly makes it impossible to get around the fan to brush away any dust. I don't know if compressed air might help ?

Thanks.

Hi, I don't seem to have any audible noises turning the fan manually. There are just the usual magnetic resting points.

Its almost like the Fan is either slipping on axel or its not working correctly of the PWM signal. Even when I use RivaTuner to fix the duty cycle at 100%, the wirring noise goes up and down in pitch and stops and starts. very strange.
