Whats a good thermal paste for a GPU like rtx3080?

[Master]

Hello everyone,
Hope you are doing great.
I'm planning on reapplying thermal pads on my RTX3080, so I am looking for a decent thermal paste as well.
Could you kindly suggest a decent thermal paste that works well on GPUs as well. I've heard there's a (slight) difference when it comes to GPUs
I did a bit of research and Arctic 5 seems to have a good reputation. is it suitable for this task or should I go for a better one, if the latter, whats your suggestion and why
Thanks a lot in advance
really appreciate your kind help in this.

Mx5 or kryonaut and gelid pads tend to be my preference.

Any GPUs I've repasted I've used Arctic Silver 5 and it's done the job well. I used it on a GTX 280, GTX 570s and my old GTX 980Ti, never had any issues.

I went with mastergel pro v2 and dropped my gpu temps by 5 degrees over stock paste.

I think alot of stock pastes and pads are primarily made of custard so it's no great shock your temps drop a few degrees

I've used Thermal Grizzly Kryonaut and Thermalright Oddesey 12.8w/mk pads on mine.

EDIT for more context.

Asus TUF 3080 (non OC, non-LHR original day 1 batch). It came with decent pads and paste already, opening it fairly much didn't change anything but piece of mind, till I found there was an extra spot to add some 2mm pad to increase contact and memory temps dropped 10c (~90-94c mining ETH), no core temp drop at all, but by lowering mem temps, I believe this has shunted extra heat to the main heatsink, so it's admirable that it didn't result in a core temp increase, and that could be at least in part due to the Kryonaut too.

Latest iteration is the stock pads between the card and backplate, full front of the card (plus extra spot) is the Thermalright Oddesey pads, ecept the memory chips themselves, I now use 1.5mm thick copper shims and the Thermal Grizzly Kryonaut on those too (used nail polish all around the chips to protect PCB and components), and get memory temps mining more like 80-84c under similar conditions.

I definitely recommend Arctic Silver 5. I've using for years with no problem.

i would not use Arctic Silver on a GPU because this paste is electrically conductive, you got to be careful like with liquid metal!

my paste Tip would be Alphacool Subzero if you can get it from somewhere, it´s an extremly good paste for GPU Die application.

Ah, this brings back memories on 8800GT 512MB, in 2010 i was playing the game Aliens vs Predator with my friends
my pc would keep shutting down and i couldn't figure out what was wrong... and later i opened up the case and my gpu was ultra hot...
my mate had some arctic silver 5 lying around and upon opening up the gpu, the thermal paste was completely disintegrated and maybe only few specks remaining around the edges..
repasted my gpu and bam! temps dropped from 100 to 65 during gaming loads...

Thank you everyone. really appreciate all of your kind suggestions.
Concerning reducing the chances of short circuiting using electrically conductive pastes, can I use nail polish around the gpus and call it a day?
would nail polish have an adverse effect on the GPU temp in any way?
I mean these small things around the GPU die:

I used clear nail polish as you say, to cover the area broadly shown how I've colored in here, and it would protect the area you coloured too. It's the poor mans equivalent of conformal coating(?), so it should stop anything conductive shorting little components out, but it won't be necessary at all if you just use memory pads, and more a piece of mind precaution for non-conductive thermal paste like Kryonaut. I'm not quite game to use conductonaut (conductive thermal paste/material)

Nail polish is ok.
The best paste for GPU is Thermalright TFX because of its performance and
mainly because of its compound/viscosity it has less pump out effect.
It is very durable and can stand high temperatures well.

Is nailpolish cheaper than solder mask I wonder, also the added benefit of getting high as a kite using it.

Its capacitive, also never had a problem using it on anything
