You mean "mess up" your hardware? No. It's not supposed to. I mean every moment your hardware is being used, it's obviously kind of using up a period of it's lifespan but it's supposed to be designed to be used and still last a while. If you leave it on literally 24 hours a day 365 days a year, you might run into issues sooner than later if you had just turned it off though.

no
its gong to idle clocks, just lowering the cpu multi, until there is something to do, then instantly changing to turbo or base clocks

if its throttling at load, then its either temps or the mobo throttling it
again, not dangerous, just limiting performance

It's actually better on your PC to keep it running then constantly turning it off and on. If you are not going to use it for many hours or days then turn it off. If you are going to use it several times throughout the day leave it on.

This is not taking into consideration power use of course.

Thousands of reboots, nothing happens.
Leaving the PC on for 1+ months, nothing happens.
The only true threat to the PC is dust buildup and brownouts (and of course fan failures).

As for that dust build-up, the Noctua Industrial fan line IP56 and IP67 are gold standard and do not attract dust buildup.

A blanket of dust on any heatsink is the real PC killer along with humidity and very high air temperatures (oh, we should also include salt water humidity as well for those on the coast).

The PC I had that lasted the most was an "always on" machine. Only got powered off due to power outages and the occasional burned PSU (bad power grid). Went strong for probably 10+ years.

Wow

It reminds me of fans and how it is best to leave a fan running than to keep turning it on and off because the initial fan spin-up is what wears down the parts and bearings faster.

Now it reminds me of opposing air circulation force against fans that can spin them faster or slower which also wears down a fans bearings faster.

For the record, all fans should be blowing in the same direction, spaced apart, not blowing against each other or too close where one fan is spinning the other(s) faster (or slower).

I think I seen setups in mid-tower cases that use negative pressure which should be installed/applied to full tower setups but then again, these people are those types that deshroud a GPU and attach water blocks.

If it's a intel cpu.

I may hav an issue with my PC. Just installed a new CPU and GPU (did not have dedicated GPU before). and an m.2 drive. The m.2 is running hot (50ºC+ at assembly and 70ºC+ at sensor 1, whatever that is). I think it's mostly due to the design of the MB. The m.2 is pretty much wedged between the CPU and GPU. And while the fans keep heat way from these components, I think the heat that radiates directly to the drive is making it hotter, especially since the GPU is cooled "below" but not a the top.
I think I will install a heatsink on the m.2 and maybe check some extra case airflow. CPU and GPU are not that hot (although it is a hot day today).
Considering that for practical reasons my case as it's rear pointing directly at me, I might switch de flow and go back to front and add some fans at the front to suck the air out.

That’s a normal drive temp. If you want better, use the given Stick-On heatsink

nvme ssd can run hot
but they will throttle and slow when too hot

if its under the gpu, you can adjust the gpus fan profile o keep the min at 10-15% to cool the ssd

It's just over the GPU. I will look into adding more fans maybe. Increasing case fan helps a little, but one might not be enough now.

So is leaving the computer on for a while with no processes really going to slow cook it when you do it over and over and over?

Me ran on linux on old Dell laptop with 24/7 no issue but heat maybe thing I worry about and next part is your electricity grid maybe problem - most cases bad cables or mixed plug-in many devices. I wonder what about your place, any problems with electricity?

Almost any desktop or laptop have to be near cool zone not catching fire nor cause fire for other objects.

Going back to the basics here.
When you say leaving it on... as opposed to what? There is no particular danger in leaving the PC on (unless you have electrical issues in the house). However, if there is no particular reason to leave it on either, better shut it down. Electricity costs money too. And while risk of fire is pretty much negligible when a computer is on, it's never zero. A bad component is all it takes and it will happen to someone somewhere in the world.

Computers are designed to run 24/7. The only concern is power usage and even that is minimal when pc is idle.

I mean you are not worried a smartphone will break when powered on 24/7 and pc is basically the same thing.

I leave my pc on permanently because it takes a few minutes to open up all my programs and documents and everything and i find it inconvenient. Im not concerned about ~50w of power it is burning when im sleeping or working, its literally pennies.
