Hello tom's hardware i have noticed my games been lagging lately and did a fix to the point of reformatting without any progress so i went to bios and saw my cpu running at 99 celcius. i tried cmos reset. I have also replaced my thermal paste with arctic silver 5. and still jumps to 99 within minutes at bios. i did not overclocked. my cooler is corsiar h60 and my cpu is i5 4670k. Although I noticed when replacing my paste the heatsink kind of had a burning or corrosion on both sides and old paste left a burnt mark on the heatsink. should i replace my cooler?
