I still find it hard to believe the big leap in performance the 4090 has over the 3090 cards. Absolutely amazing and also combined with much better air cooling as well. My 3090 ran at 70c and my 4090 barely hits 60c on occasion, and that is with a temp controlled variable speed on the fans. The 3090 I would game with it at 100% fixed on all three fans. Nvidia must have worked some serious majic with that cooling design on the 4090 card so and also runs considerably quieter than my 3090 did. IMHO Nvidia hit a home run with this design. Only thing I did not care for was the power connecters on the side of the card rather than the rear. Can make for a pretty tight fit in some not so roomy cases. Thankfully I have a huge case so not an issue on my end. I wonder if the power placement on the GPU had anything to do with the better cooling? Not sure it would really but it is curious. That's weird because my 3090 runs cool as ice. Fans never even hit 30% and are off most of the time. But I know you had an overclocked card from EVGA. They must not have done a good job on the cooling solution. My rig with the Asus Strix OC 3090 does run in the 60 - 70c temps. But that's measured during the Heaven Benchmark, which is a rather tough test - so I might compare oranges to apples without using similar apps for testing. I'm using the quiet bios for the 3090, my PC rig is more quiet than the PS5 ;-)

I'm using the quiet bios for the 3090, my PC rig is more quiet than the PS5 ;-) I have one of the earliest 3090's which is not as fast as say a EVGA FTW or the Strix OC and it has a big beefy heat sink on it. I can get the fans to crank all the way up if I overclock it to the max but then I start losing stability. I stick to a modest OC and have no issues. I'm not familiar with the quiet bios as I've never tried to use it. Does it keep the fans throttled back to stay quiet? That would explain the heat rising if the fans can't cool enough. You should probably look into Undervolting if you haven't already Rune. The 3000 series can use a lot less power and heat from undervolting while still performing close to stock speeds. Giving up say 2-3 FPS can result in a much cooler and quieter GPU.

Giving up say 2-3 FPS can result in a much cooler and quieter GPU. My GTX 1080 ran just as hot or hotter - so I don't mind the temps. Apart from Lone Echo 2, I don't recall any game crashing - I don't think there're any problems. Asus made something special with the Strix - it comes with a quiet and a normal bios - the quiet bios does reduce performance, but not much (according to TechPowerUp). Fans are not activated before certain temps - and fans rotate at a reduced speed. Asus also allows for up to 480 watts power consumption, but not sure that's activated with the quiet bios. I care most about the noise, not the temps. The card also weighs about 2000 grams - it's very heavy, so the heatsink is quite big. I'm not really worried about anything - but have been wondering if I should try the normal bios and see if I can get more performance. Then again, I'd like much more performance than 5-10% extra, so not sure I should risk more noise... Guru3D found: - and The Silence of the Lam* *cough!* Gpus TechPowerUp wrote that Asus increased fan speeds too much for the normal bios: "Just like the Founders Edition, the ASUS GeForce RTX 3090 STRIX OC has fan stop, which is ideal for keeping system noise levels low outside of gaming as they shut down completely. Gaming noise levels with the default BIOS are a bit high; it seems ASUS focused too much on temperatures. I would have preferred a quieter default setting. The ASUS dual-BIOS feature has you covered though, as the "quiet" BIOS is just a button switch away and runs much better noise levels that are very quiet, especially considering the performance this beast offers. Only the MSI Gaming X is quieter, but it's also running a lower power limit, which means less heat output for the cooler to handle." Performance was quite good according to Guru3D, so I'll probably survive losing a few percent due to the quiet bios: - but no such thing as a free lunch - Greta Thunberg may not prefer the Strix to other 3090s: Not sure the quiet bios is much slower - but TechPowerUp did write: "This BIOS switch lets you toggle between the default (Performance) BIOS and a "quiet" BIOS, which runs the fans much quieter, at slower speeds with higher temperature, and also reduces clocks slightly." Maybe time to use the afterburner, lol. Or maybe I need to test it, although a bit of a hassle removing the glass cover from the rig... Sorry about the long post, I do love talking about gpus

Fyi most GPU's nowadays ship with a quiet bios or a performance bios. You can also adjust either in the GPU settings with Afterburner, Precision, or whatever program you use - in my case would be Gigabyte Control Center. Only reason quiet bios would be slower would be running at higher GPU temps. On my EVGA 3090 I would set a static fan speed of 100% for when I ran a game. I use earbuds so never really heard the fans. Gpu would top out around 70c. This Gigabyte 4090 has hardly even broke 60c yet and that is with a variable speed fan not even running full 100% much of the time. I have a custom fan curve that idle off till it gets to a certain temp then fans slowly kick in.
I don't know how they managed to lower the temps on this monster GPU that much and still increase performance as much as it did.

Ok, not gonna ask about OpenVR Benchmark again, but I use this for temps: benchmark.unigine.com/heaven

Touching 75c, still can't hear the fans... I think..

Second benchmark run - 76c
250 fps first run

Just touching 78c, seems to stabilize now.
Using quiet bios, of course
The rig sounds slightly more windy now.
EDIT: Still 78c after 5 more min, also seeing 77c, seems to have stabilized.
Old heavily oc'ed GTX 1080 usually got 81-82c with 20c room temp.

80c would have been really bad on a 1080 since it starts throttling down at 70 resulting in a significantly slower card and reduced fps. The 3090 I think starts throttling at 80c...so you're right on the limit.
Only problem with running the card that hot all of the time is that it shortens the life of the thermal paste. Which isn't a big deal if you don't mind repasting it in a few years or replacing the card.

Why a lot of guys started looking at undervolting them rather than overclocking and raising the voltage.

Think it varies among manufacturers but most I've seen is somewhere around 80. I've never run mine that hot to see a throttle so I'm not 100% sure. I have gotten into the 70's with my fans forced off and there was no noticeable throttle.
