my 3090 suprim x is under water with ek block and backplate but memory still reaches 50c in games and 75c when i was just trying mining setup and i have stopped on mining setup due to high temp in memory.

Memory is "happy" til 100C really. It will start throttling only at 108C.

Mining causes much load therefor it is a lot of stress. More than in most games. Beides as nichrome said there is no problem with the memory temps.

Agreed that mining certain Crypos hits the memory hard. Temperature wise, I prefer to side with the manufacturer for 27/7 running (95c), if people are mining.

@robert.dorian That's really good!

I'm happy now when I stay below 70C with the GPU fans spinning between 75-100% to accomplish that when I'm in Microsoft Flight Simulator. That title seems like a PITA workout for your system!

I recently got my MSI Suprim X 3090 the first thing I did was ran Superposition 1080p Extreme on it, set the power limit to 107% with a fixed fan speed and completed that short benchmark run with a max temp of 69c which I took a screenshot, My case during this time was a Meshify C and I had to remove one of the front fans to make the card fit, test was done with 28-29c ambient and side panel off, front intake fans used was a Arctic Cooling P12 and P14

After a few days of gaming, I've moved components into its new case which is a Corsair 5000D Airflow and I was a bit surprised when I ran superposition 1080p extreme with the same 100% fan speed settings, 107% power limit and with an open side panel, I am now getting 82-83c, its like the thermal paste/GPU contact has gone bad in just a few days. I am not sure what else to check, this case has significantly better airflow than my previous one.

With an open side panel, won't that pretty much destroy the airflow through the case?

At the same time, I suppose the overall temp inside the case would be lower with an open side panel 🤔

The open side panel test was only done to replicate similar conditions done on my Fractal, which I also did an open side panel ONLY during the test, with normal use my side panel is closed. Apologies for the confusion.

In that case, it does sound very odd how your temps would be so different in this new case. As long as any other components in your system generating heat are the same as well. Also, the physical position of the GPU inside the case and how close it is to any other heat-generating sources can make a difference I guess.

If everything is the same, maybe it would be worth replacing the thermal paste. When I did this, I can't say I saw a massive drop in temp but maybe a couple of degrees.

No change of other components, but even if there was, a delta of 13-14c is very high! It still baffles me why this sudden increase in temperature. I may look into changing the paste however MSI has a tamper sticker on the GPU screw and those stickers are legal in my country.

Check with MSI in your country to ensure it's ok. >>How to contact MSI.<<

That extra 12 cm of distance of the front fans from the gpu wont help a lot may not be getting as much directed air flow over the GPU as you were in the other case.

With my older case, I had to remove the front fan to fit the GPU so it had no direct airflow. The fans I am using for my new case is a Arctic Cooling P12 and two P14's the airflow is very good and I can even feel them coming out of the PCI slots and on the vertical slots.

Wow tight fit for sure and a lot more volume of air to shift in the new case. And that bottom fan in the Meshy may have been helping to keep the temps down
I recently changed out my case fans and it dropped the GPU temp by about 7 to 8 deg in games from the old fans I had in the case.
Corsair 5000D AIRFLOW = 66 liters in volume
Meshy was 36 liters in volume
So you have almost twice amount of air to move in that case.

There is no problem with the airflow on the case, I even have the top part of the case fully sealed so that all of the airflow is directed to the rear of the case and fairly decent. I've pointed an industrial fan in a direction that blows the hot air away from the GPU and the change of temperate was just 1c. I was thinking that maybe my stiff cable extensions is some how bending the PCB and affecting GPU to heatsink contact but it seems unlikely as the card has a very sturdy metal frame that supports it."


EDIT: Even undervolting to 0.900v still gets me close to 80c, so this really tells me something is up with the thermal paste or its contact.

Seems to be getting worse, I am now getting 86c when gaming and its not even 100% GPU load!

EDIT
Attempted to undervolt down to 0.850 with 1920Mhz, still getting 75c even at at 100% fan speed, this tells me that there really is bad contact with the GPU/paste/heatsink

EDIT2:

I returned everything back to the original case same fans and placement used, Still not getting the original temperatures I used to have. Not too much of an effort as I have two sets of power cables for my PSU, still getting the high temperature so its really not the case no matter how obvious it already was.

Something definitely seems wrong.

I would follow the advice you got from MSI to have the thermal paste replaced if you're not comfortable doing it yourself.

I found a good PDF on how to do it yourself. Let me know if you want it.

Is that PDF specific to the Suprim?

Ive done a few repastes with the Gigabyte Auros Master 3080 (swapped pads with Gelid), seems like the Suprim X is far for straight forward.
