I have bought in i3 9100f and it sometimes during loading windows boot up and specially game booting gets to about 85 to 90 degree celsius!<BR /><BR />I used the fan with chipset that had thermal paste. Should I replace the thermal paste?<BR /><BR />Yours Respectfully Mon, 04 Jan 2021 09:47:03 GMT https://community.intel.com/t5/Mobile-and-Desktop-Processors/CPU-Temperature/m-p/1243022#M48808 Samul 2021-01-04T09:47:03Z https://community.intel.com/t5/Mobile-and-Desktop-Processors/CPU-Temperature/m-p/1243035#M48810 <P>No, it is perfectly normal to see sustained temperatures of 85-90c when the processor is under load.
