Spikes while working intensively or spikes while measuring in idle?
Well, this is a laptop system. Usually it's no too much wonder as laptops get heat more easily than PCs, and this is partially normal. Max. operating temp. of this cpu is something like 101-105 degrees, I think 92-95 shouldn't decrease its lifespan...
A few months ago when I was doing some little DIY customizations in my mini-laptop it seems like in one of the steps actually I didn't make a good contact surface with the heatsink and in idle sometimes I saw 80-88 deegrees, but after adding some more metal, soldering and reapplying the thermal paste, things got better.
If it's a new machine under warranty then contact the seller/brand staff; in other case you can:
clean it inside - the fan, heatsink, etc may have dust on them; can put
mx-4 instead of whatever is there between the cpu & heatsink, it 'd probably improve a bit. The screws, tightening the heatsink have to be tightened well, though
not too much, but if it's loose the contact is then loose. I guess your laptop is with thermal paste layer there. If it's with thermal pad, then mb thermal grizzly make the best thermopads, but I don't think it's a pad there, but instead thermal paste as this is cpu. Personally I also use dual-120 mm fans below my mini-laptop and I keep it above the surface (table, desk or whatever) with minidesk/4 minilegs/2 books when I can.
It's a potato laptop of mine, but I still want it healthy.
I see other people also complain about hi-temps on this cpu, though different laptop brands and models:
