Hey I have a question about my CPU, it's acting kind of strange..I'm looking at the temps on HWMonitor and for some reason my cpu temp will go to 40 degrees c and then back down to 31c and keeps doing this..it doesn't just stay at a steady temp, it's really strange..it used to not do this..even if I'm idle and not really doing anything on my pc the cpu temp will still fluctuate constantly from 31 up to 40 then back down to 31 then 40 keeps doing this..do I need to change my thermal paste or whats the deal with this..? any ideas..?
