When related to temperature or overheat, if the notebook is old notebook, most common things u want to look if the cooling fan is functioning perfectly and to apply thermal paste.
However this is not the case for Dell E5470. Looking physically this customer notebook, this Dell E5470 not too old and seems to me in good condition. So i would like to do software approach first
Format Dell E5470
First, I just want to make sure this is not high usage software / malware issue. Since this laptop contains no user data, so i just straight away format this laptop. However the same issue occurred even after i format and install driver. So this confirm the overheat issue on this Dell E5470 not caused by any applications or malware which trigger high usage.
The next step i do is to update the bios. This is quite dangerous as i afraid the notebook shut down while i updating bios. So just to be on safe side, i try to make sure the notebook really in cool state while i perform this task. You can download the latest bios version from Dell Driver website

This is the culprit. I’ve to disable Intel TurboBoost, only then the laptop cpu will not spike and causing overheat issue.
Verification – Dell Stress Test
I run Dell support assist to perform stress test. From image below, you can see the cpu being controlled around 90-92%. The stress test complete without any issue. Previously, you wont be able to install this application as it will automatically shut down your computer.
i also come across suggestion to control cpu usage through power options by controlling Maximum Processor State. Set it to 90% or below.
Power options - Advanced settings - Processor Power Management
This trick should do it if you not even want to change bios settings. I personally did not try this, as i think the bios will do a better job.
I understand that this may not the perfect solution. But as far as the laptop can be used without any interruption or sudden shutdown, i think the bios settings modification is a good solution. Hopefully Dell can come out with permanent fixes in future.
