I'm currently set up with a stock e8400 with a XIGMATEK HDT-S1283 120mm Rifle CPU Cooler. I was never concerned with CPU temps before, but I recently got the idea to try to start overclocking, and I noticed my readings with Real Temp while my PC being idle was 50°C; and close to 67°C when I run the Prime 95 sensory test on Real Temps.
I did some reading and saw my temps were waaaay too hot, even for an e8400 on stock cooling.
Thus, is there any way I can fix this? What are the usual causes for such a high idle temp? Is it safe to ignore and try to overclock my processor anyway? And at what temp should I start to worry about my processor melting or something?
I am a computer novice so any advice would be greatly appreciated.
That is crazy hot. You may need to reseat your heatsink. You also need to reapply thermal paste when you do.
Overclocked to 3.6 I idle at 28/29C and hardly ever go over the mid 50s even at load for hours. I think your cooler is actually higher rated than mine too.
For sure, that is too hot and either your setting temp software is not calibrated properly or your heatsink isn't seated properly or you put too little or too much thermal paste.
Check your mobo BIOS for the CPU fan profile and set it on performance (opposite of quiet or silent mode). Also check the CPU voltage to make sure it's not a case of overvoltage which will increase idle temps.
