Graphics card jumps from 50 degrees to 110 degreed and shuts down

[T0rvadaL]

Hi so i just opened my GPU and removed the heat sink (fan) to remove the dust, but after putting everything back together, it now jumps from about 40-50c degrees to 110c degrees and the whole pc shuts down when i load up a game like The witcher 3

I have a Nvidia Geforce GTX 760 3gb GPU

1. Take it apart again.
2. Clean off any old TIM remembering to note just how many places it was applied
3. Add new TIM to those places.
4. Reassemble.

Use 90% + isoprophyl alcohol (any pharmacy will carry) or Indigo Extreme Cleaner for cleaning

Did you reapply thermal paste to the GPU?

 

[timmoseus]

Did you clean the thermal paste off? Did you add fresh thermal paste afterward?

What are your pc specs? how did you remove the gpu fan and what program do you use to check the temps?

I didn't reapply the thermal paste (or remove it). So that's most likely the problem then? And do you have to reapply thermal paste everytime? If that's not it, could it be a static discharge or would that stop the GPU from turning on alltogether?

Take it apart again, clean off the thermal paste with rubbing alcohol then replace the thermal paste with this here http://www.newegg.com/Product/Product.aspx?Item=9SIA0AJ3KM0696&cm_re=arctic_silver-_-35-100-007-_-Product and make sure that the fan(s) on the cooler are connected properly to the board

You have to exchange the thermal paste every time, because it is designed to make a temporary thermal bond between the heat producing component (GPU in this case) and the cooler, but that bond is made impossible once the two are separated, you then need to remove the old thermal paste and replace it. It's also a common mistake to forget to plug in the fans on the cooler, I've even made that mistake once myself

the fan is working, according to MSI afterburner, GPU-Z and i can clearly hear them running. Ok thank you everyone for your freakishly fast replies, i'm going to order some thermal paste now

PS. Can i only pick one answer as the solution?

Note that which TIm you buy is important... because of the multiple application points, you will need more time to apply the TIM to appropriate locations ... depending on the card this might range from GPU to memory and VRM also. If that's the case, you will want a paste that remains pliable for along time. I'm not familiar w/ re-pasting a 760 but here's the application points on a 770

See step 2, block 3 and step 3, block 1

And remember, your cooler may not have direct contact with all those points. Many reference cards do not provide any pads, heat sinks and TIM for memory and VRM so apply ONLY to points where you can see traces of it previously being applied or for which you can conclusively determine that contact occurs.

IT WORKS! I bought the Arctic MX4 Thermal Compound, because it's the only one the computer shop had, and i read that it's really good. My GPU is even running about 9 degrees lower than what i had originally (Before i opened the GPU) Thank you everyone!!!!
