Question Does anyone know the thermal pad thicknesses for Zotac 4070 TI Trinity and have a guide or photo's of tear down?

[Darth Fattiest]

I have been using my Zotac 4070 TI Trinity OC GPU for about 5-6 months now for gaming and some mining when I'm not gaming. Was looking at GPUZ the other day and noticed that even though my running temps on GPU were within reason (75 degrees) the Hot Spot temp was over 100 degrees. I don't overclock my GPU even during mining(Nicehash). I cleaned my cooling fins and fans the best I could without taking the GPU apart. Never seen any difference as it wasn't that dirty to begin with. Fans work fine through every range of speed. I'm considering repasting GPU and replacing the Thermal Pads as I think they might have used cheap thermal pads or something. Wondering if anyone knows what thickness the thermal pads are and what should I be buying. What are my best options for good thermal pad solutions? Also, do anyone have a guide or Photos of tear down of this specific GPU. I haven't taken one of these apart before. Not that I'm nervous to do so, It's just nice to know of any potential surprises with this particular GPU before I do the tear down. Your guidance is much appreciated!

Decent pictures at least. Pads look pretty thick for the memory.

4070Ti, 4070, 4070 Super should all be the same design, maybe minor changes

Looks similar for sure. Thanks! That helps for sure! I was talking to Tech support and they said will void warranty which I already knew and don’t care about. But told me they bench test these all the time and not to worry about hotspot temp. As long as the gpu thermals stay less than 85 degrees it’s considered normal. At 85 throttle starts. Anything higher and you should be concerned. Thickness of the thermal pads range between 1.5mm to 2.0 mm. Which is quite thick. I’m still a little concerned as it shouldn’t be any higher than 20 degrees over gpu temp. Mine is hitting about 103. The GPU temp is hitting max 83-85 when she is working real hard! Normal around 73 degrees. Hot spot hitting 103 to me is concerning. What do you think? Should I risk replacing thermal pads or am I just tripping over nothing? Is there any better pads/brands then others? What do you recommend? If I do change the pads I’ll be sure to post some photos and such for anyone else who needs to do this in the future.

I water cool, so haven't really seen normal hotspot temps in GPUs.

FujiPoly is what I have laying around. But I have also used EK and Arctic pads before. The key is to have them, the differences between brands is relatively minor.

You could set a lower power limit and see if that helps. You can often retain most of the GPU performance while dropping quite a bit of wattage off the top.

Thank you for your recommendation on thermal pads. Good to know.
So I’m not convinced that the hotspot temp is accurate and seems to be affected by memory frequency. I’ve been playing around a bit and noticed that when at idle it’s less than 50 degrees and within milliseconds of starting and ramping to 100% usage the temperature jumps to 108.6ish and goes between 106-108.9. If I stop and go back to idle it immediately goes back to the normal idle temp. That’s not possible. In my opinion. Also manually changing fan speed does nothing to these hotspot temps. Maybe it’s an ave max temp? Not current temp.
Doing more research and talking to Zotac Tech support I have learned that the ram temp on GPU’s can get up to 120 degrees under normal operation depending on the frequency. Also there are no temp sensors near the ram on the zotac GPU’s only on the GPU chip itself. Depending on the GPU manufacturer they limit the GPU to 90 or 95 degrees max because the ram will be 20-25 degrees hotter. As long as the Zotac GPU is reading less than 85 degrees it’s at its top of optimal temperature range as soon as it hits 85 it will thermal throttle to prevent high ram temperatures. 108 degree hotspot and Gpu temp range between 70-80 degrees is fine for 100% load. Straight from Zotac Tech Support. The guy I spoke to repairs these GPU’s and bench tests them for Zotac. And gave me some normal results from their bench tests. They have asked me to record 15 seconds of GPUZ results when running at highest load and send them so they can confirm that everything is as per design. By the way they no longer support end users changing out their own thermal pads and say it voids the warranty. Any kind of modification voids warranty. So would changing from fan to water cooled void the warranty? I guess so. I’d love to try it! I Bet the results would be amazing for over clocking! Pushing the boundaries. I like it!

Well, overclocking isn't what it used to be. I do it because I have all the parts already.

You might gain one boost bin per 10C reduction in temps, so 50-100Mhz is about all I can expect over an air cooled card (tops out around 60C after it warms up). Not worth the money really. Now if were number crunching with this thing for days on end, then maybe. Or needed multiple GPUs (About the only way to cool more than one of these 350W+ monsters in a normal chassis)

As for the warranty, they actually can't enforce that in the US. Only physical damage would allow them to deny coverage. But because it costs more for you to sue them anyway, no one challenges them on it. So they are basically bluffing, but it would take a lot of time and effort to get them to pay out. Elsewhere they can still deny coverage.

Most of the time, you shouldn’t be scared of self-repair, no matter what a sticker says.

EVGA had a long standing policy that as long as you returned the card in the way it was shipped, all parts in place, they would still cover it. Which is why I have been buying from them for a while. With their exit, I will probably just go with whoever is cheapest and take my chances. Although, I want to give Intel a try when Battlemage comes out. I have my little A380 to keep an eye on the state of the drivers.

i have a 3060 12 gig and a 4070ti super, i use thermal grizzly conductanaut for gpu and cpu and xpc or kritical thermal pads on gpu and motherboard heat sinks as they are 20w/mk and best at conducting heat. both cards now do legendary in 3dmark and overclock very well. temp lowered quite a bit.
