Are these numbers okay for an Asus RTX 4090 Strix LC

Hello, got a great deal on a second hand "barely used" RTX 4090 Strix LC with the watercooling. The card still had all plastics on it and came with box and all, person selling said they didnt use it and decided to part ways with it since it was too much. Now i write barely used in qoutes because obviously thats what he said. So just hoping someone can help me make sure these numbers arent bad or okay, this is after 1 hour of call of duty mw2 MP with 1440p 240hz all settings high and RT ON no dlss or FG
Graphics card is OCd +150mhz on core +1000 Mhz on memory, cant seem to get core passed 180 without it messing up, thought id be able to push it more honestly.

Specs are
13900k
32gb DDR5
Hero z790
nzxt h9 elite

Processor AIO is mounted on side vents with push/pull config. GPU is vertically mounted with 3 120mm below intaking and the rad with 2 120mm on the top exhaust with 1 rear exhaust. 

THANK YOU AHEAD OF TIME FOR YOUR INFO AND HELP

The only concern here is the delta on hotpot and gpu temp.

You will have to change thermal paste, and try to keep below 20C the delta

Thank you for your response! If i may disect you a little more for info.

Are these temps something to worry about considering this is a fairly new card and its the Liquid Cooled version of it ? Also when u refer to keeping the delta below 20c what does that mean exactly?  

Would this be because of the overclocking that im doing? I ask because i feel like +150 isnt much on the core compared to some of the other post people have posted, where they have a rtx 4090 OCd a lot higher and still have way lower temps.

SORRY for so many questions, but thank you so much for all your help in advance! I am just trying to make sure i didnt spend a good chunk of money on whats going to be a paper weight in less time then warranty

Im talking about the delta between the GPU temperature and HotSpot temperature, from your screenshoots.

First one its a difference of 21C, 74C max on GPU core and 95C max hotspot.

Second one is about 25C delta, 75C core and 100C hotspot.

This delta means the difference from the GPU core and Hotspot and the normal difference for RTX 3000/4000 series its around 10C - 20C.

More then 20C difference means you have to change the thermal paste.

 

I mean you can keep going like this, because you are on limit it not really dangerous for the card, most likely when thsi hotspot goes on 105C it will start throttling the clocks, but nothign dangerours will happen. 

But as you mention its a new card, this is not a really great sign, so thermal paste always will fix this issue of big deltas.

Do you think this is something i should RMA the card for ? or does Asus allow us to reapply thermal paste?

Im very sure they will reject RMA because of this, it is still on official specs they will tell you the numbers are OK.

Because the thermal limit for the hotspot is at around of 105C and even if you card touch 105C the only thing that will happen is throttling and down the clocks.

But this is how it should work, so they will say everythign its ok,

Just like a CPU that touch 100ºC its on max and will trhorrle but no one will accept RMA because you have 100ºC on CPUs...

 

So you can do one thing, ninja change the thermal paste, like you change it by you own, with very carefful so thay never know you did it just in case.

Wait, "so they never know you did"? Are you not allowed to open the GPU? Will it void the warranty or something? Thermal pads/paste are essentially "wear parts", they have an upkeep to them. Whether they pump out or just degrade over time, you eventually HAVE to open the thing up for proper maintenance.

Its complicate....in theory you are alowed, but in practice you are not most of the cases.

This days ASUS and other brands aswell will reject RMA for any minimal product manipulation. Do you think you can do something legal against a million company after they reject you RMA even if they are not right ?

This is the cases of the majority of customers, they will just stuck with the product after RMA got rejected and nothing more will happen.

So Yes it is better to do the "maintenance" in the way that they will never know or beeing very dificult for them to discover it.

I wouldn't RMA due to this, no. The compound can break down over time, too. Hotspot is generally 15-20c higher than edge temp. Repasting the GPU is straightforward, and the AIO should be easier to disassemble.
