If the spindle is broken, you need a new fan, no amount of oil will fix it.

I'm with the others who say mini zip tie a 2500rpm fan, similar diameter to the shroud hole blowing down into the heatsink.

I had 4 cards like that (3 5830's and one 5870 (gigabyte 5870s suck))... but I took all the fans off the 5830s... They're fine packed like sardines in a 3 slot motherboard running at 800/145 @ 0.95v, w/ just the heat sink and a 12" floor fan on them... i mean, if they were in a case (mine arent, hah) that was well ventilated and ambient temp was room temperature, you probably wouldnt even need any extra cooling.

though if they had fans i'd prefer to run them at 920 core & 1.063v

oh, they get about 260mhash. at the 920 setting it's about 295, if your elec costs more than 10 or 11c, probably better at 0.95 anyway.
