Quite smart idea, not for throttling when the fans are heard, but SPEEDING THEM UP while they are NOT heard, based on the noise floor of the current environment.

This, combined with an assessment how much of the environment the user currently hears (i.e. maybe he is watching a movie), could provide a lot of headroom for additional cooling without bothering the user.

Maybe to give additional fans when the environment is so loud you can't hear them anyway

Sounds like a recipe for Heisenbugs.

Somewhat, although I guess the idea is still to keep perf flat and just throttle the cooling.

If your face gets hot, turn on the radio.

The goal is probably not to absolutely manage cooling but to focus on the audio experience and try to keep noise below some threshold. I think that's an interesting idea, even if not everyone might be happy with the tradeoff (comes down to how much you care about noise vs getting throttled), especially for a vr device.

It seems a mis-prioritization of the kind that makes me dislike Apple products. To avoid the imperfection of a bit of fan noise, throttle the entire experience. Great.

It is a machine you literally have on your head. I have not tried it, but I can believe that it requires some different UX considerations than normal computers. I would definitely not like to hear fan noise vibrating through my head.

I can certainly see things like this causing a lot of unintended consequences. "It speeds up when I play loud music" is going to confuse many who don't know about this "feature".

Being purely subjective if the user is less likely to notice the throttling than they are the fan noise, then it seems like the right call.

Wait till you experience visual stutter in VR then...

For those who are confused: the title is a bit misleading, it's actually the other way people might expect (if you read the thread)

Noisy environment: turn the fans all the way as the user -> more cooling -> processor doesn't throttle

Quiet environment: turn the fans down -> processor throttles
