Right Fan replacement, SSD and Memory Upgrade
The problem was a noisy fan.
After reading the instructions then finding the appropriate youtube video I proceeded with a repair anyone could have done. It was that easy. Do not be waived by the "requires advanced skill" warning.
I had laptop no. 2 next to me running the appropriate repair guide. This made the repair very simple.
