So I have a i5-3570k cpu and i just bought a new heatsink (hyper212 plus) to replace the stock intel one. So i removed the old one and then began putting in the hyper212. I messed up with the placement of the heatsink 3 times and each time i removed the thermal paste with a cutip that i dipped in 91% isopropyl alcohol. The the fourth time i set the heatsink down it wasn't in place so i lifted it off the paste and put it back down and got it in the right place and screwed it in. Now that everything is back in place i turned on my computer, and everything seemed fine. The temps are lower than normal at around 35C and go highest to like 45C. But my cpu% usage has gone through the roof. I can't even play games because they begin to studder and the CPU usage is at like 90%. It has never been that high until i put in the new heatsink. Could the alcohol have ruined the cpu? Or what do i need to do to fix this??
