Question DELL very hot in sleep mode

[kalemaxon89]

I often leave my DELL Inspiron 15 (i7-1139H 16gb intel Iris Xe) in sleep mode with some programs on (youtube, edge, visual studio or stm32cubeIDE, word) and when I come back I notice 90°C in each core (I'm using CoreTemp 1.18.1).
I set the thermal management to "balanced" or "cool" because I don't need a lot of performance and I have practically no background programs.

1) I am asking if this temperature is normal and what, besides the two usual recommendations (check solder paste + clean fans), what I should/could do to reduce the temepearature.

2) Are there, for example, any programs I can install that, perhaps in the background, will detect any overheating or heating anomalies?

3) Since I've always been a bit fond of the computer, I'm asking if you think this DELL (I can give you all the specs you want) has any cooling issues that I should have taken into account when I bought it .. in order that I might need it in the future to make a better purchase.
I say this because I have a fear that such a "powerful" processor on such a thin pc was a bit of a gamble.
I mean, was this warming up predictable just by looking at the specifications alone?

Do you mean the Sleep mode?

Is it this hot when it's sitting on a desk, or did you put the laptop in a bag?

Some laptops don't truly go into sleep mode, because of Windows 10/11's "Modern Standby" which lets laptops have things running the background. You can think of it like how phone apps can receive stuff and send notifications... except when on much more powerful hardware tends to do bad things. The problem however is "Modern Standby" is a BIOS feature. And typically it's locked down.

Yes, I corrected the post.

In theory, when I close the laptop screen automatically it should go into slip mode (it is written in the settings). Heating happens in these cases often

It warms up when it's sittting on a desk. Thank you for the clarification regarding "Modern Standby."
So all I have to do is close the apps before I stray too far from the computer.

Modern Standby is a system wide thing, so closing apps won't help. You might be able to disable it if you follow the things described in https://www.makeuseof.com/windows-disable-modern-standby/

But I had a laptop that had it and it ignored whatever I did in the OS for some reason. The only way I could get it removed was to use a tool that basically unlocked my BIOS so I could find it and disable it.

Beyond the suspension, I think a lot is also due to Windows inevitably running applications in the background. Just open the task manager and see the dozens of applications that run.
