While playing Rainbow Six Siege, my CPU went as high as 98 degrees Celsius, and while it's on idle it goes as high as 59 Celsius. I was wondering if it's normal to for a cpu to go that high while under load. Also I've reapplied the thermal paste by using the cooler master maker, but I'm not sure if I am able to reseat my heatsink since I'm using a stock Intel heatsink which clips into the motherboard instead of screwing. I'm assuming the best possible way to fix my temp. solution is to buy a new heatsink, yes?
