Did I Break my GPU?

post #1 of 6
Thread Starter 
So I decided I wanted to replace the stock thermal paste on my GTX 760. I removed the old paste using some rubbing alcohol and bounty paper towels. That went fine but I screwed up twice and had to remove and re-apply the paste. I finally got what I though was a good layer and put the card back together. Anyway, I'm really worried about the following things:

1. I got thermal paste on the little metal pieces right around where I put the thermal paste. I tried to remove as much as possible but there is still thermal paste left in there.

2. I think I applied too much paste. I would say the amount was slightly-larger-than-the-average-pea-size. How much will this affect performance?

2a. Because I applied too much paste, it kinda ran over the edge and got on the sides of the chip.

3. The stupid fan header was almost impossible to unclip and push back in. I banged the card around a little but I think it's okay.

4. There was one thermal pad that got pushed against some part on the GPU and it created one indent in it. I heard thermal pads were fragile but I don't think the damage was too severe.

I'm sure you can tell, but this was my first time doing this. I just really hope I didn't break my new $250 GPU.

Thanks

If it was new, why in the seven heavens would you replace the TIM?..

Good news is I don't think you broke it. The amount of paste recommended for CPUs is not enough for GPUs, because they dry it faster and generally are hotter and need more paste. It all depends, of course, but putting too much won't break your card. You may or may not see temps 2-5C higher than with less paste, but it will take longer to dry out.

1. Does your computer boot up?

2a. Usually a little too much TIM is fine, happens from time to time. Were you using IC Diamond by any chance? I would avoid using that TIM for GPU reseats, for CPU seats would be fine though. Just because the TIM is conductive and if it would get anywhere it could damage your card. I dont think many TIM's are conductive; IC Diamond is one of those exceptions.

3. Why would you bang the whole card if "one fan header" was the problem ? The fan header is a simple design. There is a plastic guide you follow, and then you plug in the header. I cant think of a good reason to bang the "whole" card around just because of one fan header? Thats like me banging my motherboard around just because i cant get a fan header out? Youre going to be damaging it from banging your card around like that.

4. Thermal pads just transfer heat from one source to another. If they bend or break or anything, just try to mend it back to its shape and put it back where it was and apply pressure the next time you reapply the heatsink/heatspreader. Its just like TIM in a different form. You cant really break your GPU; if anything you'll probably decrease the lifespan/effectiveness of the pad but thats just about it.

5. Does your computer boot up ? Or does it not, and this is why you have this thread up?

i can understand reseating a new card, my MSI Hawks had very poor TIM and the heatsink was on loose (dropped 2-3C just by tightening it...) I personally like the Antec diamond 7 paste. dropped my temps close to -7 which gave me a full -10 from stock.
hopefully it's not an asus 760 mini, heard they have gas-filled chamber around GPU... reseating one of those would be a mistake. My first reseat I used too much and got some around my GPU. it did increase my temps a little bit until I cleaned it off gently with q-tips and 90% rubbing alcohol. never use paper towels to wipe. I always use q-tips w/ alcohol to clean, then a coffee filter to polish die(always gentle), then I seat the heatsink. any kind of dust or even stray hair can ruin a perfect seat.

even if you don't overclock, you can use programs like MSI afterburner or Trixx to monitor your temps. best to use these before you do something like this, so you can see how much improvement you gained, if any. 1-2 degree drop wouldn't make up for all these hassles...

good luck with the card. thumb.gif they are expensive and even a little sensitive.. but they are not really all that fragile... as long as the components on the board were not damaged, then it should work fine. would be hard to crack the PCB or something that wouldn't be noticed immediately. BTW- most designs like that mean you plug the fan in before you put heatsink back on, usually just enough slack in cord to get it on there.

is antec 7 the same? swore I looked it up one time, but got to go to work now... I might need to consider new paste, which bites, I was getting it for next to nothing on sales and really like it.

In case you're wondering, I'm using Noctua NT-H1 thermal paste.

My case and PSU is getting here today so I'll test it out and let you know what happens.
