What on earth is "GPU Ambient" temp? (MSI N560GTX-Ti Hawk)

[Shepard]

My MSI GTX560 Ti HAWK seems to suffer from this, but what does it measure? Is it VRM's or something else? Or is it a false measurement?

My current GPU temps for idle;

gpu dioda 37c

and gpu 32c

but ambient rolls around 70c's on idle, and goes up above 90's on load. Other two temps doesn't go much above 70c's on load.

Now ambient temp just went from 70c to 50c in couple mins. It's normal for VRM temps to drop instantly after you leave a game but i haven't played anything for hours so i guess this can't be VRM's? So what is it?

Note: My case airflow should be perfect, my case is haf 932 and my other temps like cpu, disks and mb are just fine, they're about 30c's on idle and cpu doesn't go above 50c's or so, iirc.

GPU Ambient is usually the temperature of the GPU sensor chip. It is also known as GPU Environment temperature or Video Card PCB temperature.

Okay, thanks for the info, but are those temps and behaviours i just described normal? It's always higher than other temps, but on the searches i've made on google it seems to be the opposite? What is it's limit temps? Most of all, is it real? I feel like it's a false sensor or something. MSI's Afterburner tool doesn't show that temp. Please be more descriptive, i can't seem to find any info about this.

In order to give you a proper explanation, please copy-paste the full content of the Computer / Sensor page of AIDA64 into this topic.

Also right-click on the bottom status bar of AIDA64 main window --> Video Debug --> nVIDIA SMBus Dump. Copy-paste the full results into this topic.

Thanks,

Thank you for the data. We've done some test runs on a MSI N560GTX-Ti Hawk card, and found that the "GPU Ambient" measurement in AIDA64 equals to the "Memory temperature" measured by MSI Afterburner 2.2.0 Beta 11 (latest version).
