Ubuntu 22.x LTS

Are these temperatures ok for my desktop?
This is what they are when running an intensive Playstation 2 emulator.

Addendum: It sometimes reaches 89 or 90 degrees C. I have the Intel(R) core(TM) I5-4570 CPU@3.20 GHZ. 1 PHYSICAL PROCESSOR; 4 CORES; 4 THREADS. When Emulator isn't running nothing gets above 42 C.

p.s. Isn't the system suppose to shut down if it gets too hot?

Those do seem rather high to me.

The machine I'm using right now is registering 54C (so I'm going to see about clearing the vents and heat sinks for dust tomorrow). The other machine, which I'm using to watch an episode of the old mystery series, Hawaiian Eye, clocks in at about 35C.

It's not that it's supposed to. It's that it will. My understanding is that overheating is the primary cause of unexpected shutdowns.

Thanks for your answer!
Yes, I noticed my HP Desktop's fan sound faster and I almost think I smelled something.

Do you, and anyone reading this, think I should stop using the Playstation 2 emulator?
I know it' realling taxing the system as the emulator itself often runs from 70% to 100% Performance (sometimes getting choppy, etc..). I even changed a setting to let the emulator run above 100% to help make the games run "seemingly at the right speed."

Or, would you wait and see if the desktop shuts down before giving up on the PS2 emulator?

Clicking that your answer was helpful.

Check if thermal paste is ok, check if fans are clean...

Fans are cheap, so perhaps add fans for air in and air out, airflow is key.

Your cpu fan could maybe be upgraded to more efficient type, not knowing which one you have, though.

Watercooled here and highest temps never been above 40C...

Addendum: Right now I want to add an extra fan & I typed this previously & would like assistance:

Can I get another fan and just duck tape it inside the box. Is there an extra place to plug the fan in to get electrical and tell it when to kick on/turn up, etc... ?

I have about a 6 to 8 year old HP EliteDesk G1 SFF. I always think of HP having good stuff & extra connectors inside (?)

Attached is my computer.

Duct tape?

Had a search and found an image... and there's the problem with those cute, little computers...

Pretty, but there's just no options for adding fans.

I would start checking thermal paste. Based on age and recent temps, there's probably a problem here.
And make sure the "exhaust duct" and fan is clean from dust...

Best option is otherwise find another cabinet and move parts to that. You can probably find one used for nothing...

Adding a fan inside the enclosure will only hurl air around and won't help.

I think, because HP makes so many computers and names them the same, that you think my computer is smaller than you think it is.
Here is my computer, approximately:

Another solution to a too hot running cpu is:
https://man.archlinux.org/man/commun.../cpupower.1.en

Works great. Drop the CPU max frequency a little, and you'll lower the temp. I do that all the time on the 4 and 6 core machines when using ffmpeg. Fewer fps output, but a cooler running cpu, that will extend it's life.

If you have cleaned the heat sink, have good air flow, and still too hot, a solution would be to put better cooling on the cpu, even liquid cooling. Or drop the cpu frequency.

The higher the frequency with the same voltage, the more current flowing in the conductor, the more wattage dissipated.

When ffmpeg is churning wide open, I turn down the 4 core 8 thread cpu's to around 3.0 GHz, and that makes them run at around 135F.(57C)

Some CPUs are designed to run hot, and can regulate their own temperature with throttling. (I've no idea if yours is one of those.)

Even then, it depends on the case having adequate cooling, otherwise nearby components might get hotter than they want to be. (SSDs have lower maximum temperatures than CPUs.)

Check if there are relevant settings in the BIOS - maybe you can manually set the throttling temperature to something you're happy with.

Just for reference, Noctua makes some of the best air cooling solutions available, but they are rather large so not sure if they will work in your situation. My last 2 homebuilt systems (i7 7th gen) and i5 12th gen ran in the 20's at idle and the 12th gen runs in the 60's under load (gaming). I used either Noctua or Arctic brand thermal paste.

That's the same link as I posted, now isn't it?̀

Can only repeat post #6...

How small do you think my desktop is?

It's
15" x 4" x 13"

It's not one of those mini computers, but it is considered a small form factor.... I've got 2 hard drives in it & a dvd/rw

Those are questions to ask the manual(s) for the mainboard and case - presumably there's a PDF download available on the HP site if you don't have a physical version.

However, fans are not magic - mindlessly adding them does not automatically improve airflow / cooling, so if taping them is required (rather than attaching to a designated mount point) then that might be a sign it's not an effective location.
