Is there a timeout?

and thus an exploit was born.

Ya, I cant imagine that they'd forget something like that. Certainly on my iPhone Siri stops listening, which should on the PC restart the fan.

I would be very entertained if you could melt chips with an overly patient Siri.

They have to. Any time my MBP is working really hard, say, compiling, or talking on skype, or watching a video, or loading a web page, or browsing the filesystem, the fan ramps up like a turbine. It gets so bad that the microphone can't accurately pick up my voice.

Are you using an older model that hasn't been cleaned in a while? I use an early 2013 15" MBP and the only time I ever hear the fans is when I'm doing compilation with 8 threads (100% CPU usage on all four cores).

My fan rarely turns on, and it is barely audible.

It seems the tolerance is far beyond leg-scalding for my MBP, though it only gets to that point when recompiling a bunch of version specific libraries in a sandbox for over 10 minutes.

I have an MBPr and do frequent 1080p/4k renders that utilize all 4 cores to max, and I can barely hear the fans...

I'd assume it wouldn't be a timeout, but a higher temperature threshold. If the machine is on the verge of melting already then you wouldn't want to turn off the fans at all.

I've got a 2015 15" mbpr, and it doesn't take much for the fans to reach noisy speeds. one core pegged will do it after a few seconds. I run into this a lot with the new docker daemon.

edit: just timed it (yes > /dev/null), it takes about 60 seconds of one core pegged to ramp up the fan to audible. And I'm used to silent so audible is noisy to me.

Two cores pegged gets loud.
