[Official Guide] Modifying/Removing NVidia GPU Heat Spreader/IHS - Page 13

post #121 of 257
My experiance would show that if you still having heat issues after modding the issues are with the TIM application. It is so easy to mess the TIM when reinstalling the cooler, more so as without the heatspreader as you have even less cooling surface and the effects of a poor TIM job can be maginfied greatly. The tell tale sign will be hash flutuations in temps. Simple things such as web surfing and seeing temps fluctuate 10c, this would be a good indicator of poor TIM application. IMO, if your going to go through all the work of removing, lapping and reinstalling you may as well leave the IHS off completly and run directly on the chip. When using zipstraps youll never get them so tight as to crush/damage the chip anyways......in most cases that is...things happen lol.


Nice change to the first page layout. Only thing i dont like is how the wording is lost with the backdrop image, or that way when viewing on my cell phone.

With the side panel on furmark hits about 84 top card and 80 lower card, they idle @ 35/33 as well. I believe my airflow could improve and be much better lowering it into the 70s, with a more aggressive fan profile it does go down about 5c to 75/76 on 65% "palit fans are noisy as hell". The mod corrected the heat issue i had with the upper card tenfold given i even down clocked that card at it was hitting 99c while the other hit like 55c on the lowest frequencies. I suppose i could work on my cases airflow with stronger fans and applying a stronger side fan. think t he haf 912 supports a slightly larger side one which i can add in.

I googled to see which cooler people were using and found this thread. I dont wanna sound like a dick but has everyone gone soft or something? It's just a heat spreader...

There's a lot of misinformation in this thread also. Whoever said that the leads on the PCB are raised at the same level as the die is wrong. They're not. If you have an aftermarket cooler like mine it will not short the contacts on the card, because the die is raised.

I'm shocked that anybody on here would leave that piece of crap on their card.

And whoever said 10/10 risk level...

Few things since your new here...
387

anyway...

1. I think a concern was the possibility of the heat spreader mounted improperly which would lead to the transistors connecting and frying the chip... The way the heat spreader is designed if you were to put it back on the chip and you placed it improperly or something shifted, then yes, because the heat spreader has lower levels on it, it can infact touch the transistors on the side of the chip. You can tell visually that the transistors are not the same height as the die.
2. When you say, "a lot"....explain.. you just mentioned 1 thing. One possible concern someone raised of a potential short in the chip is not misinformation, its called people being concerned for their GPU.
3. Some people don't have a choice but leave that piece of crap on the chip. If you mod the IHS right, you can get nearly as low temps if you had the thing completely removed. Some coolers due to height won't allow you to mount it directly to the die. For instance, stock ASUS Direct CUII heatsink won't allow it because the heatsink hits the VRM heatsinks. If you tried to seat it on the die it'd be a mess.
3. Yea it was kinda being a D*ck. You can ruin your card quite easily trying to remove the IHS. It's a concern that should be raised because people might not be as handy as you are and thus the reason why to display that concern to people. The last thing you'd want to do is make this guide sound SUPER easy then have someone break their GPU because you didn't warn them enough to be careful.

I think all parties that plan on using an aftermarket cooler should remove the heat spreader. It's a pretty major hindrance and is clearly only there to lower the number of RMA's due to people cracking die's. Kind of reminds me of when Intel threw the liability of bent CPU pins in the motherboard makers lap for the same reason.

Remember when CPU's had pins?

Its a great mod. Obviously its very dangerous but its nice actually modifying the parts and then having a 10C+ drop in temps!
Gnom,
Yea I know. I see charts of ATI cards running lower temps than Nvidia and thats probably so because of this heat spreader issue.
My guess, they add the heat spreader to protect the chip. Maybe ATI has more damaged chips by vendors...I don't know, and Nvidia is trying to be proactive in reducing the margin of error for bad chips...? Since older chips seem to be without this heat spreader. That would be my only guess. It's just proactive safety measures to reduce the cost of ruined chips. Think, it's probably a good 5-10% cheaper to just add a 2mm piece of copper to the chip and glue that down than have to replace chips on cards that have been damaged in production. If I had to point to a reason, that's my reasoning....But that's just the business side of me talking...I could be wrong, it could be some engineering spec? who knows

That's what I said. Removing the IHS is a good idea but, like I said before, people might not be as technically inclined to do so. Yea it might be a great thing but if you were that person that either left your card alone and just changed the TIM or tried this mod and ruined your card...yea I think we get the point.

Seems like with AMD they have like a copper shim to protect the die since they don't use a heatspreader...I'm hoping NVIDIA goes to this with their kepler but we'll see...might need to crack the IHS again with keplers...
post #127 of 257
Well there's a reason that they put that IHS on there, it clearly is not a performance enhancement. A shim would be a better idea, like you said. This way you have protection so that the heatsink surface cant wobble off the die and crack an edge.

Like some other people said in here too, the stock cooling solution on the Galaxy is really not very impressive when you get it off the card. It's dwarfed by the Arctic Twin despite the identical fan size.

I was so tempted today to attempt to remove the heatspreader on my i5-2500k.... I think I might want to practice it on a few dead chips before I attempt it on a $220 CPU... You can actually see the glue between the green chip and the IHS....ARG! So temping! My only fear with modding the CPU is the way the CPU is seated in the socket, if I sand the edges, it could potentially reduce the pressure that the mount has to push the pins on to the CPU...so that could potentially be dangerous...hmm

Do it, and let us know how it goes. Just dont use my CPU. Really like the thread though

Ok, someone please help me understand.

Is there a risk of shorting something out with the antec 620 strapped directly to the die? In other words, if the cooler's copper surface came into contact with a couple of those transistors, it would fry my gpu?

Also, is there not a reason that there's a space between the top of the die and the bottom of the IHS?
