Question Need Help Regarding a Second-Hand Card

[Majhang]

Dear AnandTech Comminuty
Hi, I hope you're all doing well.

I purchased a second-hand MSI 3090 Gaming X Trio from a miner for an excellent price. Almost, as much as first-hand RTX 3060 Ti in my country.
The miner used the card in a very good environment, but before paying the guy, I deeply tested the card for a few hours with Furmark, Afterburner, and HWMonitor. Everything seemed fine: No artifacts, no fan noise, normal clock speeds, and the physics of the card were fine.
Now I installed the card on my system and the thing that is bothering me is the card temp. While on windows, the fans stop, and the core temp sits between 49c to 51c. But when heavily gaming, like Resident Evil 4 Remake with RayTracing, the card reaches as high as 80~83c.

My question is that should I be worried about these temps? My previous card was an ASUS 6700 XT and it never reached 70c, even in the most demanding scenarios. The guy gave me a week for testing the card and I can refund it if I want to before the end of said week, but other than the temperature, everything is fine.

PS: I updated the VBIOS via MSI Center to enable the Resizable Bar, which was a success.

Any help is greatly appreciated.

For a card that has previously been mined on, those are excellent temps. You can try to reduce the temps more by undervolting the GPU.

You may be able to drop the temps by 10 degrees celsius, or even more.

The core temperature sensor isn't too helpful by itself. Check out HWiNFO to see your GPU Memory Junction temperature. You will wanna be under 100C at max load. Stock RTX 3000 is inefficient, so anything over 0.850V (stock boosts over 1V) is gonna make your card really hot with minimal gains. Creating your own custom voltage curve inside MSI Afterburner is definitely the way to go.

I undervolted the card to 1850MHz 0.825V. That did help the temps by a few degrees. Should I undervolted it further? Any suggestion?

Only a few degrees? You should get your card repasted with fresh heatsink paste. Maybe you can find a shop that can do that for you, if you are not too keen on doing that yourself for fear of damaging the card. Maybe you could also get the RAM chips thermal padded by the same shop.

Also, make sure that your case has good airflow with fans arranged in a push-pull configuration.

Thanks everyone, but my question still stand: Now with undervolting to 0.825V, temps sit between 75-78ish. Are these temps safe or should I be worried? I ask this, because I still have a few days that I can return the card.
Regards.

I wouldn't be worried about those temps. They're warm, but within reason.

Ambient temps, case ventilation, these should be checked first before discussing undervolting and/o repasting. The MSI Gamign X Trio reaches 73C in a 21C room in a very well vented case. Any increase in ambient temp or decrease in case ventilation will result in higher temps even on a new card.
