i have the Intel core i5 2500k .i haven't done any overclocking or anything really just today i left my PC open to download something
when i got back home i found out the the PC is turned off due to there was no electricity for some time
when i opened instead of logging into windows he give me a choice to boot new windows or to start windows resume so
i opened the bios so while i'm there i noticed that my CPU temperature is too high it even reached 85 despite there was nothing stressing The CPU because as i said i'm in the Bios so i checked the CPU Fan (Stock cooler) and it was running at 2400 RPM and still the Temperature kept going up so i checked if it was installed correctly i even took it out and then put it again and nothing and when the Cpu is Idle the temperature is 55 i don't know what's the problem should i get thermal paste or get an aftermarket cooler ?
i should note that i installed a new windows because i couldn't log in the one that was installed
i think i will go with an aftermarket cooler because those temperatures are really annoying so what aftermarket cooler should i get? (the voltage of the CPU jumps to 1.200 could this be the cause for what this is happening )
1.2 will not give you too much heat(i do not even think that is over voltage for that cpu).
My personal favorite for the price is the Coolermaster 212+(easy install and works well). The new 212 Evo may be a good option if the price is not too much more.
In the bios, the cpu's power savings features are not running. This can result in higher temperatures as the system sits in the bios. But 55 idle in Windows would say you have either a loose/damaged pin on the cooler.
