I finally dropped the money on a 3080 and while the switch allows me to run my oculus rift cranked up and my reverb G2 with most things medium or high setting quite comfortably, the GPU memory (just the memory, not the GPU itself) cranks up to about 106c in VR game play. Under the oculus it gets to about 102c. The card has 3 fans, the case has 3 inlet and 2 exhaust. This sim really puts your hardware to the test! Granted, I don’t really have any problems. The system runs great. Nvidia says these are normal temps for a 3080 but I was curious if others cards are running this warm as well. As soon as you come out of VR everything goes back down to say 50c-60c.
You have to have something wrong. The Gpu shouldnt go over 90c. I have the 3090 and it is between 70-75c on full load. If your card goes over 100c its going to destroy it.
Yeah I think my 3080 gets to around 70c or so in VR or just playing on the flat screen. I don’t think VR taxes the GPU any more than playing in 2D at 4K with most settings on ultra.

I’m just talking about the memory on the card, not the GPU. The GPU itself runs low-mid 80’s at full load.
106 on your memory GDDRX6 is fine. It can take up to 112 before it will reduce performance. My memory is most of the times around 104 a 108 with my MSI 3080 ventus in VR.
My GPU temp itself is most of the times around 60 till 65 max.
No worries on this temprature, it should be fine.
“For reference, Micron rates its GDDR5, GDDR5X and GDDR6 memory chips with a Maximum Junction Temperature (TJ Max or Tjunction Max) of 100C (degrees Celsius). The typical recommended operating temperatures ranges between 0C to 95C. The reading materials on Micron’s GDDR6X don’t reveal the TJ Max for the new memory chips so there’s still a bit of mystery to the topic. According to Igor, the general consent is around 120C before the GDDR6X chips suffer damage. This would mean that the Tjunction value should be set at 105C or up to 110C.”
My Gigabyte 3080 runs reasonably cool compared to the OP in FS2020 VR, sitting at around 62C GPU and 86C memory temperature on average. My case has 3 x 120mm inlet fans and 3 x 120mm outlet fans, 2 of which are for my AIO water cooler for my OCed i9 CPU, which runs at 5.2GHz on 1.35V Vcore, HT Off, and ranges between 50-60C itself in FS2020 VR. Room temp is around 18C (mid winter here in Oz).
What specific 3080 do you have? Some run hotter than others just due to better design and cooling. I have a Zotac 3080 amp holo model and it ran super hot. I ended up pulling it apart and replacing all of the thermal pads internally and re-pasted the heat sink. On average I dropped the temps a good 10-15c
On Zotac especially, but the stock thermal pads on most of these cards are junk.
ResetXPDR What headset are you using? My G2 is pretty taxing. My original oculus Rift not so bad. Runs the card a little cooler.
My card itself I wound up buying an HP Omen 30L that came with a 3080 and pulled the card and put it in my machine then sold the rest of that machine. It’s got three cooling fans on it that force the air upward and out a couple exhaust ports. I would rather it have a bunch of exit holes on the cover instead of the exhaust ports it has. Seems other aftermarket cards that I have seen have a bunch of holes in the GPU case for this very reason and I like this idea better. However, if you look at the Nvidia founders edition sold from Nvidia themselves, they are set up just like my card with just a couple exhaust areas.
Mine is the G2 too. I am running OpenXR with no custom render resolution set and in-game FS2020 RR at 100% and other graphics settings all high with a couple at ultra. GPU sits at 99% most of the time and even running FS2020 VR for a couple of hours, like I just did, my temps stay pretty constant.
Ok that’s pretty much the same setup I’m running as far as the game and WMR settings. I also have three inbound 120mm fans and two 120 exhaust fans. A bit warmer in the room though about 77f ambient. Running an I9-11900k stock configuration but that processor rarely gets out of 70c on full load. I think they should have provided a little better air flow on the video card but it does run within specs so I guess that was good enough for them.
Until I watercooled my 3090 (including a backplate waterblock) I was less than happy with the temps, however, my entire rig is built with a focus on watercooling so putting the 3090 in there with its stock cooler did skew my internal cooling - a case optimized for air cooling/air flow might have got a better result.
With the cooling blocks in place the temps are now well under control.
MSI Gaming Trio 3080 here. I replaced the thermal pads on the memory modules on the front and back of the PCB and saw a 25c improvement. I mine when I’m not gaming and the memory junction temps would throttle constantly without it.
Pretty frustrating. I get cheaping out on components for a Zotac card, but it’s unaccepatable to me on a higher end gaming card to use poor conducting pads that leave an oily residue all over the memory modules and PCB. I cleaned everything with 90% iso alcohol prior to adding new pads.
