Problem solved! It wasn't any piece of hardware which was causing the CPU get hot and fan run like crazy. It was one of Dell-preinstalled pieces of software and namely: Realtek High Definition Driver! It was sucking over 25% of CPU resources, temperature of CPU would be always above 70°C. I removed the driver and during the restart Windows found its own driver which now run quiet. I see CPU won't go above 50°C now in idle-mode so back to life :-)
Those temperatures are too high. You should be idling at 50-55°C. a Temp of 70-75°C is reasonable during many applications. Check the Task Manager and see what the CPU usage is and what programs are using resources. There may be some programs running in the background using mucho CPU time. The Windows indexing program is one of these that will run a lot in the beginning till everything is indexed. You should stop this program in the services section, as it really is not too useful for most users.
Well, there were some services which could be causing this excessive CPU usage (dwm.exe, indexer, sidebar). I deactivated all of them. Before CPU was like 55% used, now 25-30% but still the fan spins like crazy. I am reading core0/core1 around 70°C.
I too have a excessive fan noise problem with my new laptop. I'd like to try this solution, can you please confirm the file name that I need to remove? Thanks
I had a similar problem where the Fan got very loud every time the CPU reached close to 30%.
I found out that the issue is with the integrated Intel Graphic controller. If you go into the the Control Panel -> Intel Graphics and Media -> Power (on the left side menu ) -> Select Power Source - "On Battery" , then uncheck the "Display Refresh Rate Switching" check box, the problem is gone.

Hope it makes sense,

Thanks for this suggestion. I'd like to give it a go. How do I locate the driver and remove it?

Thanks for the findings. It really helped me in reducing the temperature from 70 degrees centigrade to 45.
