GTX 470 screw problems

Hi

Taken a guess at this being the right section.

My EK water blocks came in the post today so I thought I would fit the gfx card as its the one I can do and still use my pc. However couple screws wont come out the back so looking for advice on how to get them out.

1.Just turns on the spot but doesn't come out. I have tried gently turning with magnetic screw driver but it wont come out. Almost like there is a nut on the other side that is rotating too but I can't see a nut or anything similar. (I now have this screw out)

2. Was really tightly done up, applied a bit more pressue and the screw driver jumped and has wrecked the head of the screw. Anyone know a way to get it out short of drilling it out, as I could like to try to avoid it.

Thanks.

The only true way to get it out is by drilling in the center of the bolt & removing the head.

That is what I am trying to avoid but it is looking likely I will have to do it.

Thanks for the replies, I tried those tricks already Oldphart, seems to be stuck solid

After trying everything I can think of (short of epoxying a screwdriver to it) the head is well and truely ruined.

Well looking at the pcb, there is a small area of the orange which I guess it is to do with the screw holes and not something to do with the working of the board.. I am trying to find someone who has a bench drill to drill the screw out straight or a hand drill so I can do it slowly and carefully. Just insanely paranoid about having a gtx 470 paperweight. In theory should only need to drill down about a mm to drill out the head at the moment I am not concered with getting the thread out of the stock cooler.

Edit: Diggsy, that was suggested on another forum I asked on. The screw so close to being flush it makes so difference. No Pliers I have or could find in dads garage could get a grip on it.

It is only that screw that is holding this together now. So is the orange colour parts round the screw ok to to hit with the drill or does it need to be 100% accurate.

Wouldn't it make sense for the manufacturers to just sell the card without coolers to solve all this trouble.

Not sure why thermal pads came up, with the 470 ek block, they are the same thickness but different sizes and tells you where to put them.

As I couldn't fit the gpu block i spent most of last night fitting pump top, checking out rad, figuiring out where everything went and the final route of my loop etc. Oh well only 4 hours until I can do some more work on it

Yh this is my WC cherry popping. Everyone said it takes longer than you expect and to be honest I am hoping that to have it done asap to minimse downtime but I am going to take my time as nothing worse than killing a whole pc. I am confident in my pc building ability just not my drilling ability haha. I would love to be able to have it running by sunday night but I doubt I will be able to get 24 hours leak teasting in this weekend so maybe next weekend.

Hahaha well I hope I can get it build a bit quicker than that, don't know if I could cope with no computer for that long haha. I have no plans any evening and delibrately made no plans for this weekend so I am hoping I will have enough time.

Its off

My jewelyry friend re cut the head of the screw just enough to be able to get a flat bladed screw driver on it. The board is immaculate still.

One question though, cut the thermal pads slightly wrong and don't have enough of the one listed number 1 which goes on the chips, missing one chip. However I do have a square of number 2 big enough, can I use this or do I need to work something else out?

Greboth · 28 Oct 2010 at 22:19

yes they are all cut to shape, just I think I cut them a bit too big as the last bit for the last chip only covers about 1/2 - 2/3 of it but I have enough of the other left to cover it. Guess I will use that then, once that done it block on time.

It was like a dremel but a smaller than dremels I have seen and he was using what looked liked a really small routing tool, just a small diameter abrasive tool. He put it in the middle of the screw where the old philips head was a re channels just enough to get a small flat bladed screwdriver on it. The screw is totally ruined now though but at least its out so I can re attached stock heatsink if I need to.
