cpu sensor faulty?

ive got an i5-650 with it's stock cooler. ive recently been beginning to notice that after about 15 mins or sometimes less of gameplay on games like Sea of Thieves and fortnite, the frames drop from a solid 60 (cap) and go down to about 20 and less, so im guessing some thermal throttling. however, when i went to feel the heat made by the cpu, there was not much more heat coming from the cpu than it was when its idle. So i installed msi afterburner, and when launching a game the cpu temp increases to 105^oC! so im wondering if my frames drop because my cpu throttles becuase it thinks its overheating? i dont know ¯\_(ツ)_/¯ (when its idle though, its about 60-70^oC)

Yes you're thermal throttling. You either have a cooler than is no longer holding its pressure with the janky mounting system that intel uses, or you have dried up thermal paste.

Yep those are bad temps all around. Check the cooler. If it's full of dust clean it, change the thermal compound, make sure the fan is spinning.

Yeah you are for sure thermal throttling 105c is terrible, and 60-70c idle is defenitely higher than what you want, most coolers can keep a cpu while idle under 35c and full load is usually in the mid 70s not the hundreds, anything over 90c is not good. Like others have said check the cooler/thermal paste get it switched out asap.
