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.

I have a strange problem...
I have done it on 2 cards and then the fans were working again - BUT only for a few minutes, then they freezed...
now the fans do nothing, but they are easy going if it rotate it manual Huh

you probably damaged one of the windings. you don't need to insert the screwdriver/tool in too far.

The screwdriver method works for sure, I have used it a couple of times on a problematic (read crappy) XFX 7970 fan.
Saw it first time demonstrated (with three screwdrivers) by this guy on a different type of fan, but the principle is the same:

Ok.
This method don't work for you.
Choose whatever you want.

Its really funny every one saying its my method.
They know how to install graphics cards, know how to put 1-8 or more graphics card in a system which designed to put only 2 graphics card & they calling it "whose" method.

Whatever, I got problem, asked forum, some one helped, problem solved.
The purpose of this thread is done.
I hope in future some others may find it useful.

Well I tried this method and destroyed the little PCB under the fan. Now it's super dead

Quote from: AndrewBUD on October 09, 2012, 09:22:39 AM

Well the fan and heatsink are identical to the ones in the picture...
I tried this method and killed it even more

I don't care.... Just stating that drilling a small hole is a LOT easier Cheesy

So far you didn't show any pics of YOUR BROKEN FANS & PCB's.
Stop trolling.

I threw out all my fans that broke even more with your method. If you want to buy me a fan so I can demonstrate how fans break with your method, I'll gladly show pictures or a video of how it breaks.

That's okay my 2 year old is demonstrating how broken the fan is...

I am trolling because I didn't put up pictures of the fan I broke? The fan already had it's connectors cut off.. I tried to separate it to test this "method"

Here are a couple pictures, you suck.... here's some tissue too..

1) Its not MY method. Some replied me & i thanked him.
2) If AndrewBUD can able to drill a small hole, near center without breaking any parts & make his fan works, saying he broke fans by opening is clearly absurd.
He can able to drill, but can't open?
Which is easier & safer?
Drilling or opening?

I've been able to pop reference fans and non-reference FirstD (Sapphire) fans no problem.
Obviously you need to be careful where you put the edge of the screwdriver and make sure you understand what you are doing.
You can't just go in there like you are using a crowbar on a 2x4

Your fan may be ball bearing type.
Remove sticker on back side of fan.
If you see a small black rubber piece on center or a silver ball bearing, then you broken a fan which can't open in the above methods.
So far, I have seen only 2 types.
Ball bearing back type, which needs to just remove sticker & put a drop of oil.
And no ball bearing type, which can be opened by the above method.

You better post pic of your fan, which you saying broken when opening.
Also, the fans you have, which so far not broken.

Without seeing any pics or details of fan type, NO ONE CAN HELP.
You keep on saying you broken fans. Better show pics of broken fans.
