Hi, I have the GeForce RTX™ 3070 GAMING OC 8G (2.0) and I had an overheating issue causing the GPU to shut off (Screen black, No signal), but that was resolved by changing the thermal paste with Arctic Silver 5 and that actually fixed it, but like an idiot I also decided to change the thermal pads which was also a recommendation thinking an overhaul was due. So I got these from Amazon 1mm thickness https://www.amazon.com/dp/B09V52D1N1?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

I also cleaned the thermal paste and reapplied. Once put in, at idle temps were 35+ and I thought that was strange, its usually around 25-30 tops. Then I ran it through FurMark and instantly screen shut off and froze and I saw a hot spot jump to 108 instantly. Stupid stupid stupid. I should have just left it, it was working fine. Man, I didn't know how important the perfect thermal pad on the areas around the GPU processor actually are. So there's my problem.

So, I need to know the exact thermal pads that GIGABYTE uses on their GPU since this is the issue. They are a thin sticky rubbery gray type. It was working great with just new thermal paste replacement, but as soon as I changed the thermal pads, immediate overheats and shut downs under load. Those pads from Amazon must not be the right pads. The original one's I pulled off were stuck and ripped apart.

So, please tell me exactly what I need to get this card running the coolest it can be. Thank you.

It worked!!!!

The k5-pro putty paste came in as well as Thermal Grizzly Duronaut.

I am serious impressed. A huge huge improvement.

Normally using FurMark putting the GPU to the max stress, I was average 74c and hot spot 105. It would spike to 108 and crash it hence all my problems with the black screen no signal issue in my other post.

So I applied new Arctic Silver 5 just on the GPU core and it made it stable and was running average 74c and now 88c for the hot spot. It was steady under load, but not good enough.

So then I applied the K5-pro just like in the video. I gooped it on pretty thick fully covering the VRAM and the other areas that had the thermal pads. Then I applied the Thermal Grizzly Duronaut on the GPU main...

Gigabyte have a number of RTX 3070 cards in their portfolio, which one do you have? To add, do you yet have the original thermal pads or did you discard them? If you do, you can measure the thickness of said pads.

In any case, you might want to take a ruler or vernier caliper and measure the distance from the components to the heatsink's mating surface.

You could also use thermal putty if you don't want to go through the hassle of measuring;

Sorry, its this one GeForce RTX™ 3070 GAMING OC 8G (2.0)

I re-used the original pads that survived, but when pulling off the other two, they ripped, got stuck, and disintegrated.

In that video it showed the thicknesses needed. Is that my problem? I used 1mm, but in that video its showing 2.5mm. Can that be? The ones I pulled off were paper thin more like what I would assume 0.5mm would look like. Is that the issue, I didn't get them thick enough?

Important part is pad thickness.
Different graphics card parts will use different thickness pads. One thickness for vram, different thickness for voltage regulators, different for mosfets..
Using only single thickness pads will not be enough.

If some pads are too thick, they will prevent proper contact for gpu chip to cooler.
If pads are too thin, then component under pad will not transfer heat to cooler properly.

You have to measure old pads.
Then get appropriate thickness replacement pads.

You mean this one? Please be specific since not all cards are made the same and won't exactly have the same thermal pad thickness or amount, for that matter.

Take a look through this reddit;
and see if they conform to your card, considering you're the owner who disassembled the card.

Yes that is my exact model number.

I watched that whole video and read through and I am still slightly confused on what I need to go with. I don't want to do that messy paste, but would love to just get back to factory. In another thread, someone said Gigabyte got back to them and they said they use size 0.75mm, NOT 1.0mm like I currently have. Also, I think the quality of the thermal pads I have are just not good. Once again at any sort of stress test, immediately jumps to 105 hot spot. Prior to this, it was at 88 steady.

So, I need to know exactly what compound Gigabyte is using, because theirs feels like a sticky rubbery silicone in gray, but the stuff I got is like a non sticky gritty clay.



EDIT: After a lot of research I am going to give the K5 Pro paste where the thermal pads once were. I'm also going to go with the Thermal Grizzley Duronaut and will use that on the GPU chip as well as my CPU.

Before you settle on using thermal putty/paste to replace the thermal tape pads, just know that the clean up is or can be harder to do when or if you need to replace it. I would just try to get the correct thickness thermal pads or try multiple thickness pads and even stacking them.

This post seems to have what appears to be more accurate thickness pads.

If you are going to stick to thermal pads, don't buy the cheapest, because it's often intended for devices that have the tolerances for higher temperatures, but you also don't need the best on the market which are going to be very expensive.

When replacing pads, you need to properly clean all the components you are replacing the thermal pads on so you have proper application.

I would have recommended you don't change the thermal pads in your original thread about the GPU black screening, but I think I deleted that part of my post when I did a rewrite on one of my posts. I don't change thermal pads unless they become damaged like ripping them a lot or I have something on hand that is far better.

Then I applied the Thermal Grizzly Duronaut on the GPU main core. A huge drop now down to 53c average under full stress load and the hot spot is now 65 stable. Wow, seriously impressed.

Here's how I installed the K5-pro and Thermal Grizzly Duronaut

Here are the results.

I applied the Thermal Grizzly to my CPU and it actually didn't seem to make much of a difference. Maybe under extreme load temps were a little lower, but I am not sure sine idle seems to be exactly the same. Under heavy gaming and max load, the CPU temp is around 54c. So that's not bad for the Intel i7 13700k, but I am not sure if it made a huge difference for that. But for the GPU, day an night difference. A total game changer, literally.

Thanks guys for all the help. This case is closed and SOLVED!
