What is this big piece of metal doing on my gtx 470m?

Whats the deal here? its about 3mm off the board.

Any way to get it off? or what laptop this was even made for?

Its so big that I think I'd have to bend my heatpipe and then I'm not sure the screws would reach to the right places.

Spoiler :

I haven't really tried to just stick it in there yet. I really don't think it would be a good idea without any modifications.

Do you think it would be an extremely bad idea to try and file it down?



Last question that needs to be asked, out of the sheer small possibility; could this be a quadro 3000m or 4000m?

Its a gf104-400-a2.

At first, I would assume it was a quadro card based on where I got it from and how much they know. Then the SLI connector made me think it couldn't be a quadro, but lo and behold, the newest quadro cards are pictured with an SLI connector.

Also in the past with the g9* cores, all the quadro cards had a 900 number, 770m, 3600m & 2700m were 975 and 3700m was 985, so I don't know what 400 could mean (actually I've never seen a model number so low). perhaps things have changed. what do you think?

Only option I see is tinfoil the full board except the heat-spreader and try to heatgun melt it off.

Most likely is is glued on by thermal epoxy.



Or if it's done like at the cpu-s then gl .. only hard force can remove it .. and that is more then dangerous.

Really? That is the GPU... Why would you want to tamper and remove the heatspreader on your GPU? And a GTX 470M is a GF104 part.



I suppose if you didn't care about your warranty then go for it, have fun taking the risk of destroying your GPU and with no warranty afterwards.

Because he can't re mount the heat pipe system.



Took a few cpu apart .. and the metal heatspreders is 1 waste of material ...

Only good they do is to protect the silicone .. but they keep the heat on it more then taking it away.

Without it the cpu stays a lot cooler.

That 470M looks a lot different from the ones I've seen.

Are we talking plastic surgery or microelectronics?



My guess is that it was put there for a reason. But then again, what does NVIDIA know, they only designed and fabricated it.

I would go for the 5850 for 300$ with a free copy of MW2.

Reply 7 : What is this big piece of metal doing on my gtx 470m?

Where did you get it from?

Five finger discount...

haha^ I guess so...



superdooper49: And you would be paying more money for an older, worse performing card. I dont think I need mention the value of MW2.



sama98b: Actually I could remount the heatpipe. I just don't feel like it. If I did that I would probably go ahead and get a new copper sink and 2 bigger pipes. But is heatgunning it really the only option you see?



Any comments on filing the heat spreader?



mushishi: I know its gf104. And I know its the GPU. I bet you didn't know the quadro 3000m and 4000m are also both gf104 and the the 4000m is 100w with a 256-bit memory bus. Aaaand what warranty are you talking about?? who bought an OEM laptop??



H. A. L. & ichime: Yep, yes it sure does. Nvidia likely had no idea what they were doing, especially considering the 100% chance of this being an ES card.







I don't know how I'm going to mod my heatsink or the card yet. I do think it is a 4000m however. So I'm going to hold off on anything ambitious for now until I write up why I think its a 4000m
