Sudden fps dropping and inconsistency

[LucidityyMC]

Suddenly about 3 days ago my fps in the games i play (LoL, CS:GO) has suddenly gone from its avg of about 200 to 30 - 40 spiking down even lower. I checked my BIOS and it showed the CPU at about 78 degrees which i am pretty sure isn't too good, and just today i blew the heat sink out with a compressed air can (made sure i didn't discharge static) and it hasn't changed any ideas?

Try reseating your CPU's heatsink back on, and reapply the thermal compound. If that doesn't work you might have a broken heatsink or something is wrong with your CPU. I honestly think it sounds like the heatsink from what you're saying and if it does turn out to be broken, heatsinks are fairly cheap.

Im not sure if i want to do this as it may void the warranty. Is it better just to replace the cpu as a whole?

Almost certainly isn't the CPU itself; simply sounds like overheating due to the Heatsink to me.

Important information would include what CPU you're using. 78c is definitely concerning with an AMD CPU, not so much with an Intel chip.
