980ti thermal paste question

[Dimetime35c]

Okay so I'm guessing that the stock thermal paste on the 980 ti acx 2.0 from evga isn't exactly the best but not the worst. I have replaced it using IC Dimond but I'm not sure I did it right??? I used the line technique and did a single line from the bottom of the chip to the top. Will that be enough????? I've been to scared to power it on. I noticed a lot more compond on the gpu then on the cpu when I first opened it. How much do I need? I'm just scared I f'ed up and the second I turn on the card it'll fry.

take the cooler back off and see if it has spread across the entire gpu chip, if it has then clean it off and use the same amount again. Is IC Diamond ok for gpu tim? hopefully someone will aswer this question as I cant.

Draw an X pattern then a + patter. Copy Jayztwocents example in this video

if the thermal paste is non conductive it will be fine

Also replacing stock thermal paste on GPUs is a waste. As Linus demonstrated here, replacing stock thermal paste only resulted in about a 1-2 degree difference.

Difference between CPUs and GPUs is that there is a heatspreader on the CPU, whereas there isn't on a GPU and you're placing it directly on the GPU, for that reason, more thermal paste is used so that it covers the entire GPU. With a CPU which uses a heatspreader, you don't need to cover it to the edges, only a reasonable area of contact is needed.

You can turn it on and see the temps. Too much is better than not enough, and it won't hurt the card. Even if you put WAY to much on there, it will run warmer, not WAY HOT. You will be fine, test it out, see if thermals are any better than before, and if they are, I would leave it, if they are the same, I would leave it, if they are worse redo it.

Most of the time yes.

But Gigabyte has for example used different thermal pastes on their G1 GTX 980. One of those thermal pastes is really bad and gets quickly hard after a few weeks.

I replaced it on mine and noticed an improvement of 4-5 °C.

Check temperatures at idle first, and if it's too hot, turn it off and try again. Most video cards throttle to stay at 80°C or less, so in the absolutely worst-case scenario it should just throttle heavily and/or shut itself down to avoid damage. In any case it's highly unlikely that it would overheat that much at idle. Just don't throw FurMark or Crysis 3 at it until you know it's running as it should.

 

Chances are, assuming you followed most of the advise we use for thermal compound on CPUs, that it's at least going to run at a safe temperature.

Typically how long should it take for the paste to harden? When I removed the heatsink thing it looked like there was hardly any paste on the actual gpu and most had like squished out the side. There was a bunch of it like built up round the sides and on the indentation where the chip sits higher then the rest of the board. I removed all the paste with 90% iso alcho on both the chip itself and the heat plate thing. Then applied the new paste to just the chip.

Thermal paste should not harden at all. It will eventually at some point, but that should take at least 2-3 years.

Good thermal paste is even after 5 years wet and easily removeable.

Come on man. Who are we kidding? In the video it's clear the temperatures dropped by 3-4C. Now, that's at roughly 65C. For someone who's GPU runs at 80C or so, the reduction will be greater, at about 5-6C at least.

Why on earth would you quote me on a topic from a year ago?
