There was a recent thread regarding GPU fan speed whilst playing games but this one is different....
After openning the Oculus desktop app (Core 2.0) GPU temp is rising from an ambient 37 deg to 65 wihtin 2 mins with no VR app being run.
Weirder still is that task manager is reporting no GPU use (well less than 1%), closing the desktop app returns temp to normal.
I've been running the latest nVidia 390.65 for 2 weeks and this has only just started happening so I don't think the driver is the culprit. Anyone else having this issue?

Hi @Asryan2a
This is still an issue and I haven't heard of a fix. I've gotten used to closing Home whenever I've finished using my Rift but that's not a proper solution. I'd really like to hear something official about why the GPU is being worked without the Rift being worn and whether a solution is being worked on... both for this and for the specific issue that Windows is not reporting any GPU use whilst this is happening.
By the speed that my GPU rises in temperature, I'd estimate it's running at maybe a third of its TDP. I can only guess how many people leave Home running after exiting a game not realising that this is happening if their card is like mine and remains silent. It's annoying if you're anything like me and super conscious of energy saving, not to mention avoiding unnecessary wear & tear on components. At least this GPU use isn't cumulative when using the Rift... it just shouldn't be there when not gaming.
All I can say is once again, close Home when not wearing the Rift.
Oculus, any chance of some input on this?

I think what I'd question is... why is Home a 3D app when all that's active is the desktop 2D browser. The virtual desktop is created but that in itself is just an extended 2D desktop with a higher resolution unless I'm mistaken. If Dash is running, does it need to be without the Rift being worn?
When you put on the Rift, there's still a loading process for the 3D environment so it doesn't appear thet your VR Home is being pre-rendered, so what exactly is the nature of the work being done?
As I say, a lot of people probably leave Home running on their desktop without using the Rift and that's drawing power, I think unnecessarily.
And the other important question being GPU use reporting... it just isn't happening for the virtual desktop. Windows reports 0% use with the card (at my guess) at 30-40%.

You misunderstand what @Asryan2a and I am saying, we're not saying that people are running high resource apps. We're saying Oculus Home is the app that's demanding GPU resource, when the only thing running is the desktop 2D browser element of Home. Which is what's happening for everyone that opens Home without wearing the Rift, i.e. before you put the Rift on or after you take it off.
This GPU use is not being reported by Windows, meaning when you open Windows task manager, GPU use is reported as being at 0% or close to it depending on what other apps you may have running. Even though GPU temperatures are rising to indicate approx. 30% to 40% use. So there is clearly a problem with GPU reporting for the Virtual monitor.... the virtual monitor is what's created as soon as you initiate Home, regardless of whether the Rift is in use.
If you don't have temperature monitoring software, you probably won't be aware that your GPU is being worked if it remains silent which mine does at this level of usage and that makes correct reporting via Windows quite important imo.

Hey LZ, where you been?
OK now I'm curious! The temp on my Maxwell Titan rises from an ambient 37 to 69 in approx. 5 minutes and takes around 3 minutes to return to ambient when Home closes, maybe less.
This high is no doubt a combination of factors including what speed the fan is set to and the power draw. Mine is at stock speeds which is around 1000 rpm at ambient rising to 1400 at 70.
You could be right that this is a result of a power state change, not GPU usage but for my card it's a huge rise in temperature for no gain during Home use without the Rift in use.
I guess what I'm saying is, there must be a lot of people like me (and Asryan2a) who are having significant temp increases indicating not insignificant power use and if this is the route cause, I'd still like to see a fix whereby GPU power state isn't increased until the Rift is in use.
I'd welcome other people's input regarding their cards temps and what their card is... also curious how this effects 2080ti cards which are already stretching the limits of the ATX power specification!

Yeah all totally valid points, that is quite a jump .... mine are not as sharp as yours, mine is cooled by water AIO, so the ramp up and ramp down temp takes longer to equalise. But the temp difference between Oculus App running and not running (without HMD being on) was quite minimal, a couple of degrees C.
