HP Spectre 15 x360 Overheating?

[Ai_Ex]

Hi all,
I've recently had a swollen battery repaired by HP. This had caused damage to the outer-casing of the laptop as well as the touchpad/keyboard.
I've been trying to identify the cause so I can reduce the chance of this happening again.
It appears that overheating may be a cause of such. 
I have been checking my notebook's temperature since repair.
It has been idling between 55-70 degrees Celcius. When using certain applications, it reached temperatures of 85-90+.
I performed a thermal stress test, and these were my results:

Start Temperature: 71, 69, 64, 64, 62, 62, 61, 61
End Temperature: 87, 87, 87, 88, 84, 84, 88, 88

I have undertaken the recommended procedures: cleaning vents, checking for updated BIOS/drivers, ensuring space and a hard surface etc. 
Is this reason for concern? I don't know how else to reduce my notebook's temperature even when it is hardly utilising the CPU.
