Vostro 3491 possible design flaw block the air vent by the open lid
Dear Dell Community
This is a strange thing indeed. In most laptops the air vent in on the side of the laptop. Here in Vostro 14 3000 (i5 10 gen) the air vent is at the back of the laptop.
But when the Lid (screen) is open, the lower edge is COVERING those vents... Thereby making the cooling much less effective.
Is this a known problem? Is there any logic in this shape of the Screen bottom (it could have been less low there). I wonder.
Thanks

To an extent yes it blocks but definitely not fully. The laptop does heat a bit more than normal & for sure can't be kept on the lap. Poorly designed & cheap laptop. Have the same 3491 laptop.
I use it always always on study table or dining table.

As for the not heating - That depends on what's running. The latest Bios update (to 1.10) improve the situation, but still, the design is stupid... No other words.
I wonder if there are any electronics in that lower edge of the lid...
Thanks

Thank you for staying connected. I'm Vivek, and I will be assisting you.
If I have understood correctly, you’re facing an issue with the System Heating. We will look into this for you right away. I will need your help in performing some simple steps to identify what’s causing this.
As the system can result in heating due to multiple factors, we will need to perform a few checks and troubleshoot to find out the root cause.
Let’s first update all the drivers and BIOS on the system.
You may follow the instructions from the below video for the same.

Once this is done, test the system and check if the system still heats up.
If yes, then follow any of the below videos and disable the Turbo Boost.

From my own testing it doesn't make much (if any) difference to the CPU temperature whether the lid is up or down, measured under a steady load with the fan running. Wouldn't like to speculate on the effect on any components living near the exhaust vent.
Still it is quite curious how rapidly the processor on my copy hits 99C-100C under a full test load and has to apply TCC throttling to prevent a thermal 'event' (though it's easy to adjust the TCC offset on Linux so it stays under 96C, say).
