780ti INSTA Overheat

[KamuiSC]

Hi.

 

   So I recently upgraded to a 1080ti and I took my old 780ti out of its water block and back onto its default shroud but now, in a different system, it instantly overheats under any amount of load other than idle?!

I am told that VRM thermal pads may be the issue but how much of an impact will those tiny thermal pads that are in direct contact with the shrouds plastic really be able to have?

 

Other possible issues I can think of include;

 

1) Some sort of damage during reconstruction

2) Incompatibility with the old MOBO I was trying to put it into

3) Shockingly ineffective thermal paste on the GPU?

 

IDK, any help is appreciated.

Thanks.

Did you put thermal compound on the GPU die?

[Tiwaz]

do a clean eapplication of thermal compound (dont use too much) and properly mount the cooler

who and how is controlling the GPU fans?

sounds like you screwed up the thermal paste application, or forgot about it all together.

on a GPU you should use non-conductive either way, and you need to make DAMN sure that that entire die is covered.

I applied the thermal paste in the same way I would on a CPU, should I have applied more? I tried with 2 different, equally shoddy thermal pastes.

I tried with EVGA Precision.

wrong.

 

on a cpu you have the lid, and the moment you spill, it's all into the socket, which is a mess.

 

on a gpu you dont have a lid, which means that if the silicon isnt completely covered, it's not cooling everything.

 

in fact, gpu's come with quite a generous application of thermal paste out the factory

Alright, I'll try again. Thanks for the help

I learnt this the hard way when on Friday my 1080 got smashed up with an hammer from accidentally firing too much liquid metal paste on the die.

 

having to sell my phone to pay for the 1080 I've just had to purchase.
