CPU temperature jumping at idle?

[Mechanics55]

I am using HWMonitor to monitor my i7-4790k. It usually idles around 33C with a Noctua NH-D14 but for some reason it will occasionally randomly jump up to like 40-50C for a split second and then return to my normal idle temps. Is this a software error? Also my clock speeds constantly jump around from 800MHz (my usual idle clock speed) and will soemtimes quickly jump up to 3-4.4 GHz then back down to the normal 800MHz.

Hi Mechanics55, I don't think there a very simple solution, this thread discusses problems that looks like yours http://www.techspot.com/community/topics/cpu-usage-spikes.10830/page-2. Did you have a look at your process usage or anything? Did you change anything in you configuration?

Your CPU sometimes has to work harder to process information. It should jump from 30C to 40C for a split second and come back down once every few minutes to an hour.
