Sparkle gtx460 non-reference runs loud

[edgaraslt]

I know that it's crap card because it's non-reference. But when it was brand new,for about 1 month, it ran with no sound at all (idle).
Any suggestions how to fix it? Oil fans? Clean "heatsink"? Or put aftermarket cooler?
It makes bad sound even when it idles (40% fan speed(minimum)). I undrestand that I can't make it silent on load,it sounds like a boeing.

Yes to cleaning the card and if the fan sounds like the bearing are grinding then oil.

But if it is like this

Then you are in trouble.

Well yeah, when I set fan to 60-90% it sounds like this. Maybe little queiter.
But at 40-60% it's queiter.

Would it be very difficult to remove heatsink? Ir it's maybe possible to put some oil without removing anythink?

btw. temps 29c(idle) - 70c(nasty load)
