GPU hotspot and Gpu tem differences

[hermesa]

So on my ASUS TUF A15 with ryzen 7435hs and rtx 4060 8gb laptop I have in stress tests(furmark) like 78-79 gpu temp with 90-92C hotspot temperatures while in my desktop pc with ryzen 5600x and rx 7700xt the gpu temp is 50 while stress testing and hotspot is 80-81C while stress testing with furmark.On my laptop I changed the factory thermal paste with MX-6 and the thermal pads(it was factory liquid,not pad but I pasted Upsiren U6 pro for VRM,chokes and mofsets) , I don't know if that's normal for laptop or for dekstop pc...While gaming I have no bigger than 8-9C difference on the laptop.I know that under 10C difference is ok , but is 15C difference during stress test good ?

15C diffo is fine. You have your hotspot way below 110C so don't you worry but 50 to 80 is kinda unhealthy. Your desktop GPU heatsink doesn't have a proper contact with the die. But since you're at 80C at most you don't need to worry.

My desktop GPU(rx 7700 XT steel legend x3 fans) is never opened for maintance (it's still under warranty but), I bought it 9-10 months ago and never dared to opened it since it's temperature never reaches more than 55-60C while heavy gaming with full max ultra giga settings at 1440p

Are you seeing any thermal throttling? No? Then relax. Furmark is not a particularly realistic workload anyway. And a hotspot of 80 is still within the reasonable realm.

rx 7700 xt VRAM temp is 70C ,hotspot 82 , GPU temp 47C with fun curvature - 30C-40% , 40C-50% and so on,And the laptop gpu reaches 140watts only under stress testing , never saw more than 95-100w during gaming

No , not at all at least my desktop. In laptop I see thermal throttling a cpu(45watt tdp cpu with default enabled boost reaches up to 75-80 watts with 90-91C and jumping to 95C in loading screens) but I limit it to 50W via G-helper and temperature max is 80C in the cpu intensive games without loosing much FPS , when I disable boost at all it reaches 70C max during heavy cpu intensive games and 60-65 in gpu intensive games

Your question is fundamentally scuffed. I mean this one:

While gaming I have no bigger than 8-9C difference on the laptop.I know that under 10C difference is ok , but is 15C difference during stress test good ?

You just cannot reasonably compare laptop GPU with a desktop discrete one. Especially from different manufacturers. They will behave differently. But, as I said, for your 7700XT those temps are fine and the delta between GPU and hotspot is an irrelevant metric - the hotspot temp varies wildly between different samples of the same model of card from the same AIB. It just doesn’t matter unless you get actual throttling.

Now I saw it's more than 30C , 78C hotspot with 45C in-gaming CyberPunk 1440p Max settings

It’s fine. I don’t know what else to tell you my dude. Do you want to just confirm your biases that “high hotspot = scary”? It’s not even high. And the delta between it and core GPU is, again, irrelevant. If you are really bothered you can try disassembling the card and swapping the factory TIM for a PTM pad or something. Might make a difference. I wouldn’t bother.

I wouldn’t bother.

Me neither. Their temperatures are very safe. I'm running my GPUs hotter for decades and nothing dies.

In all my years using PCs I've never "opened" a GPU for maintenance. The result is I've never repasted a GPU or laptop CPU. The opposite is true of CPUs, because I upgrade systems regularly and occasionally treat them to new CPUs. The result is I don't worry about hotspots, even when I'm running a GPU flat out at full rated power for 36 hours in a rendering run.

Some of my GPUs are more than 10 years old and they still work. The most I do is clean the fans, but only when moving a GPU to another PC. Stop worrying. It'll be fine.

That delta is kind of high. You could try taking it apart, applying new paste and putting it back together (if thats an option with the laptop, idk), being sure to screw each screw in one turn at a time for even pressure. Or you could just... not do anything. Up to you.

That's what I think of but not sure because of the warranty(it's a 3 year warranty and only 10 months passed since purchase). I'm talking about the 7700xt desktop gpu.On the laptop after reapllying thermal paste MX-6 and Upsiren U6 pro thermal putty again I got lowered temperatures , max 66C on memory temperature(it turned out I have sensors for VRAM on my laptop) and the problem turned out to be that I applied too much thermal paste on the GPU die.But what bothers me now is the GPU hotspot temperature on my rx 7700xt desktop gpu.At idle my gpu is 21C with hotspot of 24C , but when I start gaming I get max 55-56C depending on the game with hotspot of 81-84C.I take a look at the vram pads from what I can see without opening it , and it seems like they are in good condition and in good contact with the vram.

Update , changed thermal paste , not much difference - from 35C difference now its 20-25 difference :v
