Applied new thermal paste to GPU - worse temps?

[Trumerik]

Hi!

I recently got a 1070 from a friend. He had it for quite a while and it was a bit dirty etc so I decided to refresh it.

I took it a part, cleaned it and I also applied new thermal-paste. I used Thermal Grizzly Hydronaut because I heard it was one of the better thermal paste. However when I put it back in my system the card reaches 80° which I don't really fancy since it was running closer to 70-75° before. What has happend? Do you think I should re-do my application?

 

Thanks.

Yes, re-do your thermal paste application. Check if you've put enough, and make sure that you tighten all the screws with the right amount of force. Also, when you take it apart, you should check the thermal paste imprint and see how it spreaded, so you know what you've done wrong.

Hi, thanks for the quick answer. Ok I will do this, can I just add some more thermal paste in that situation or should I remove and add new? I mean since I just recently put it on.

And also, how do I know how much force is the right amount? This was my first time.

Always remove and start over. You have thermal cycled it at least once and when you just add more you could introduce air bubbles which is basically an insulator.

Ok, thanks

*update*

Re-applied, reaches 80° but the fans seems to be running a bit slower. I am satisfied.

Did you play with the fan curve? Could up the curve a bit to get temps down if 80 is too high for you but seems like on a low noise profile 80 under load would be pretty standard.
