My i5-3570k, and my asus gtx 670 have been idling 5°C hotter than normal recently. My cpu would idle around 28-30°C now it idles at around 33-35°C, and my gpu would idle at a constant 30°C and now it idles at 34°C. My ambient temperature has not changed and i haven't done anything to my case to cause this change. I have a corsair 500r with an extra intake fan at the bottom and exhaust in the rear top slot. Everything is at stock setting minus the voltage which i lowered using offset. My cpu cooler is an evo 212 with 1 fan on it.
