20% - 25% of CPU being used at idle with all apps closed...?

[Prof.]

Like the title says, my MacBook Pro is using 20-ish percent of the CPU. This is causing my computer to run hot. The CPU heat-sink is 122ºF. Anyone know what's going on? This literally just started 20 mins ago when I booted up my Mac when I got home from work.

EDIT: Heat sink is now at 140ºF and climbing. Fans are turning on.

Sounds similar...

After 15-20 mins of going ******* crazy, just like that it stopped... I'm thoroughly confused right now

Mavericks has been one giant nightmare...

Don't watch it so religiously. 20 minutes of low-to mid CPU utilization is no indication of a problem.
