I have an i3-2120, it's a couple years old but recently I began noticing very high CPU fluxuations and idle temps. Going from 45-55 and back and forth and sometimes and often idling at 55 which is certainly not normal. I've tried cleaning the inside and it doesn't seem to fix it. Both fans are running fine. Any idea what the problem is?


Rest of my PC specs are


Operating System
            Windows 7 Ultimate 64-bit SP1
            Intel Core i3 2120 @ 3.30GHz
            Sandy Bridge 32nm Technology
            4.00GB Single-Channel DDR3 @ 665MHz (9-9-9-24)
            ASRock B75M (CPUSocket)
            Acer E230H (1920x1080@60Hz)
            1023MB NVIDIA GeForce GT 430 (EVGA)

Are you certain the cpu is actually idling and not running tasks in the background? I would keep an eye on the cpu usage in task manager under processes. Sometimes software, updates, or malware will use the cpu and cause higher than normal idle temps.
