I have the same overheating issues with my Dell 5401.  I have the model with discrete Nvidia graphics card and whenever I use a graphics "intensive" application (inverted commas because they really aren’t that intensive) the computer gets very hot, the mouse and keyboard start to lag and audio goes crackly.   

I've noticed that Microsoft Teams will almost always cause my machine to grind to a halt within minutes, with the base of the machine getting roasting hot when sat on my desk.  This problem is exacerbated by using the Dell WD19TB dock with one or more external displays. 

Having diligently been updating the BIOS, firmware, etc since purchasing the machine 18 months ago, the problem has finally been solved by using a cooling pad.  I’ve followed similar posts for other Dell models with the same processor (i7 9850H) that recommended disabling C-states in the BIOS, which did improve things.  The problem is slightly bewildering because the model I purchased was supposed to support three external displays, which clearly it doesn't have the necessary cooling for.

I’d be very interested to know if anyone has similar issues that have been solved by providing additional cooling

Following a couple of service visits via Dell ProSupport, overheating was diagnosed and the cooling system replaced.  Just made it through my first MS Teams meeting with all peripherals attached.  Fingers crossed, this problem is solved. 

Hi,

I have replied to you from a private message.

Hi there,

I have the same problem. The 5401 laptop fan is always running at its maximum speed causing an unacceptable loud noise.

the laptop is so overheating to the pont that the mouse pointer is sometimes lagging.

Any recommandation ?

 4.Dell Power Manager Service 

https://www.dell.com/support/home/en-my/drivers/driversdetails?driverid=7866h&oscode=wt64a&productcode=latitude-14-5401-laptop 

• Launch the application and under the Battery Information, click “Settings” set for battery setting change to from “Adaptive” to “Primary AC Use”.  
• Go under Thermal Management, customers can select “Cool Mode” if they would like the system to run cooler. 

• Go under Thermal Management, customers can select “Quiet mode” if they would like less fan noise. 

5.Download and install the Intel Processor Power Management Utility à System will need to restart. 

https://www.dell.com/support/home/en-my/drivers/driversdetails?driverid=39kkn&oscode=wt64a&productcode=latitude-14-5401-laptop 

1. Users Must ensure Windows power plan is set to “Balanced”. 
2. End users Must also adjust OS performance setting to “Better Performance” when connected to AC power. 

• OS performance setting can be adjusted by left clicking on the battery icon located in system tray and just slider to “Better performance” as below. 

It's very possible that there is dust blocking air flow/coating the heat sink and causing thermal issues (hence high temp and loud fans). However, clearing this out might required a little more than spraying some compressed air into the fan, because this will just loosen the dust. You might have to take the machine apart, however because it sounds like you are talking about a corporate owned computer you probably shouldn't open the device up and should probably request someone do this from your IT department.

Hi,

As we have not heard back from you since our last interaction we will be archiving this case for now. Do reach back to us if you have any query.

did anyone noticed the fan AND the heat sink blades are a lot smaller than the 5490.
Also if I can read the charts correctly the CPUs use a bit more wattage than the prior models, this is particularly true in my environment (i5)

not sure how the engineers think that upgrading the fan to a brushless fan was a "good enough" trade off in order to make the heat sink blades a lot smaller

Did anyone else noticed this?

Go to BIOS and shut off Turbo-Boost.....Worked on multiple here.

5401 running HOT loud Fan Fix

Ensure latest BIOS is installed

Manually install the below driver & utility. These are not auto installed by windows or Dell Command Update

Intel Dynamic Platform and Thermal Framework Driver

https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=64c9j&oscode=wt64a&productcode=latitude-14-5401-laptop

Intel Processor Power Management Utility

https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=p9cyy&oscode=wt64a&productcode=latitude-14-5401-laptop

After installing these, fan noise is reduced except when CPU is heavily used. Laptop is cooler to the touch, especially when idle or light use.

Any updates on this? I've downloaded and installed the latest BioS, Intel Dynamic Platform and Thermal Framework Driver, Intel Processor Power Management Utility, and disable Turbo Boost, but it is still noisy like an airplane without a big workload

Bios 1.24.0 seems has solved this issue.

I think Dell manufactures some heaters with built in laptop in it I also face the same heating issues with my latitude.

Hi All

I’m experiencing the same issue with my Dell Latitude 5401 I5. At first, I thought this problem was unique to my machine, but after reading about the similar experiences from others, I’ve come to realize it’s a common issue with this model.

I’ve been regularly updating my BIOS, but it hasn’t helped reduce the problem. If anyone has successfully addressed or troubleshooted this issue, please share your experiences.
