Your CPU may have slowed down on Wednesday

I'm not familiar with the ZBooks, but if they're as thin as the EliteBooks and ProBooks, and the cooling is as much of a joke, I can't say I'm surprised, especially with a HQ CPU.

My ProBook with an i5-8250U spins up its fan for no reason while doing next to nothing on Linux with i3. And no, there's no "borken power management because Linux" issue, the battery actually lasts a long time (comparable to the official specs, which are presumably for Winows).

But curiosity got the best of me one day and I opened it up. The cooling system is an absolute joke. The heatsink is ridiculously small, my iPhone 7 probably has a bigger one.

Same story with an EliteBook something, with an i5-7xxxU CPU. I actually switched the EliteBook for the ProBook because I could add extra RAM.

However, I don't have any "slowdowns or stutters" with this machine, and I usually run it attached to an external 4k screen.

Mine is more than a inch thick, I'd say it's about an inch and half thick. The cooling system is probably a joke on mine too, it often reaches 80°C while being idle.

Could be worth a try: did you open it and blow some compressed air through the heat sink? I did this when my MacBook was some 5 years old for the first time, and it helped with temperature and the fans would stop revving up during normal use.

That's really bad, maybe it's an option to repaste the CPU. Because this isn't normal.
