5970 fan suggestions

[lightlord]

This is what my card looks like



Getting it RMA is out of the question as its two years old, and I bought it from another person.
And The fan is having problems, and when I turn it with my hands I can feel a resistance, or a tug.
I went out and bought sewing machine oil, as I heard that works better then olive oil as they break down
eventually, though I did put it in one of my cheap fans, not a graphic card fan, but a $6 computer fan.
Ironically its been spinning and working for the last 4 months, and it spins extremely smoothly,
with no problems, and when I push the blade from turned off, it moves very smoothly, where before
it was hard to push.

Though eventually it will break down and destroy this fan supposedly.

Now I ask, where do I place the sewing machine oil? On top of the fan? Or I open up the card,
and turn it the other way, and put it from the other side?

I am not a computer idiot or anything, I have done some basic modding such as modding a 6950 card
with a wire from VCC to HDD in a controller on the card, and hacking it for more shaders.
I know basic computer stuff, but not as much as about the fan.

So I like some advice before I proceed ahead.

And one thing I like to say is I know enough about computers to know how truly little I know about them.

Best regards
Lightlord

The oil may prolonge the life of the fan a little bit.

But ultimately the best is to replace it with a new fan, as your bearings are probably worn out: http://www.ebay.com/itm/New-ATI-Video-Card-4870-5970-5870-5850-4890-5450-5650-4350-Replacement-75mm-fan-/271103944516?pt=PCC_Video_TV_Cards&hash=item3f1f0de744

My friend told me that this fan is completely detachable. The trick is to pull out turbine (not shaking) when the fan is holded with screws to metal plate of the cooler. I never did it  myself but he told me that this is not big problem, he uses graphite grease and told me that fans run very silent. Other thing (safer for me) is to drill holes on top of fan (maybe 3 is enough) carefully with dremel and put in little oil (engine). I have one defective fan 'modded' like this and it is working very fine.

I've re-oiled plenty of fans: GPU, laptop, case fans - they all respond pretty well. If the fan is seized or broken, they you're SOL. I wouldn't try to separate the fan, as not all of them do actually separate. Just take a 1/64 drill, and poke a small hole in the back side. Dap a few drops of machine oil into the hole, tape it up, and you're good. It's like $0.10 to try, and if it doesn't work, you can pick up a new fan on ebay for like $10-15.

This method works on the AMD Reference Card "Squirrel Cage" type fans. It is as easy as it appears in the video. I have used it on my 5850 and 5970 Reference Cards. I use 3 dessert spoons as levers instead of the screw drivers shown in the video. Once you pop the impeller off you will see why the "drilling a hole" method can work but its really not a long term fix, and you do need to get the hole in exactly the right position.

I did it today, just more little power and the fan is out, used universal lithium auto grease for bearings.

yes, i bought 5 fans from that guy as well -- about 6 months ago... back then they were like $10 each and a bit less in bulk, though.

i've used 3 of them, no problems from those

the non-ref cards get ziptied 120mm fans (or none at all, I have 3 running in a case w/ just a floor fan blowing at them.. i dont think that'd work in summer though... but I guess I wont have to worry about that!)
