CPU temperatures for Core i5 2400 model
Check for unusual background tasks or potential malware consuming CPU resources.
You have a fresh Windows setup and suspect the thermal paste might be the cause. Since you haven’t replaced it and the machine has been in use for two years, consider checking if the previous owner had it changed. If unsure, resetting the CMOS can help resolve boot issues.
Voltage appears normal, I plan to buy fresh thermal paste tomorrow and install it on the PC. I'll let you know after completing the task.
It sounds like a fresh paste and cleaning should help. Because it isn't an overclockable CPU, you might also lower the voltage slightly to cut power use and heat. A 0.050 to 0.075 reduction is usually safe for most Intel desktop CPUs; just verify stability afterward. Reducing 10-20W can noticeably affect temperatures and fan noise in certain systems.
Thank you for your message. I processed the new thermal paste today and chose a pea-sized amount. The results were noticeable—CPU temperatures fell considerably. At idle, they stayed between 40-45°C, while gaming reached up to 62°C at peak.
