Dell Inspiron 5570 heat problem

I disabled the turbo mode but it isnt the solution.It is a spec of the laptop.It should run fine even at 4GHZ.The cooling system is really bad

Dell basically made a joke out of this computer. Put a powerful CPU only to limit it by an extremely poor thermal solution. It's only a 15W TDP CPU... I installed ubuntu on mine and within 4s from a cold bootup, the OS is already reporting that the BIOS is thermally throttling the CPU and that's even before the OS is finished loading. Have to treat this Dell as a 1.8GHz Max CPU.

I am also having heat problems with my Dell Inspiron 5570. It gets too hot in 15 minutes that i can't touch even the keyboard comfortably.

I don't have the same Inspiron model as you, but my experience may be helpful. I am posting this on every "why is my Dell laptop so hot" thread I can find in hopes that more folks will see it.

From the time I bought this Inspiron 13 7000 brand-new in January of 2019, the built-in keyboard has gotten hot enough, especially on the left side of the keyboard, to make typing uncomfortable. Since I make my living as a medical transcriptionist, this is not a good thing. I use it with a laptop pad with a USB-powered fan, and even that was not of enough help to cool down the keyboard.

I followed all the suggestions I could find on multiple online searches, including updating the BIOS as well as making sure all the Dell updates had been downloaded and installed. Still too hot. I even went so far as to remove the back of the laptop to check and see the condition of the fan. (It was fine. No dust.)

And then I happened upon a suggestion to disable the Intel Turbo Boost Max technology in the BIOS. This is enabled by default and, if I understand it correctly, basically overclocks the CPU, which makes it run hotter. I had earlier downloaded and run a program called Open Hardware Monitor which told me my CPU core temperatures were running in the high 60s to low 70s degrees Celsius.

So I rebooted the computer, hit F12 on restart to get into setup, and found my way to the Turbo Boost. On my system, it is found under "Performance." (Your mileage may vary.) I unchecked the box to disable it, saved the changes, and finished booting up the computer.

And now the keyboard is no longer burning my fingers, and the CPU temperatures are running in the high 40s to low 50s. And I can put my hand on the bottom of the computer without it hurting.

this is exactly what happened to mine as well. it was new so dust wasn't the issue and so as thermal paste. curious really about why this happens.
