How did you disable Turbo? I regularly hit 90 when I start running unit tests or compile xcode. I've gotten into a habit of preemptively setting the fans to max before doing anything like that now.

I use https://www.rugarciap.com/turbo-boost-switcher-for-os-x/ to disable Turbo Boost - it requires some weird permissions, but seems to work alright.

Corollary: when in doubt, don't.

If you want to interact with the cpu directly it needs to be a ktext which is part of the kernel.

This ability will be removed in 10.16

That's what the TURBO button on the case is for, duh

I felt so cheated when I discovered that the Turbo button was actually a way to slow things down when you turn off turbo. I spent so long as a child "running the computer responsibly so it doesn't overheat"!

I also recall the patches people had for things like Jazz Jackrabbit that ran a busy-loop some number of times in hot code because timing was execution-dependent in games like that. Faster CPUs made the game unplayable!

I absolutely loved playing Jazz Jackrabbit, wasn't expecting to see a reference to it, thanks for the nostalgia :)

Intel Extreme Tuning Utility lets you tweak almost any parameter but it only works on Windows, if you have dual boot you can use it though (I think) as it persists settings to the firmware/BIOS. For MacOS there’s e.g. “Volta” I think which can help.
