Let me start by saying this is a new build i put together yesterday (sig). I feel like my temps are kinda all over which im not used to seeing. Below is a gyazo gif of my temps displayed via HWMonitor. This is while idle. how can a core temp jump and drop 18ºC.

Any feedback would be greatly apprecaited. I did use the thermal compound that came with the noctua but ive read several places that its high quality.

Your 1st screenshot shows the CPU is trying to idle ... look more carefully at Power and Frequency and watch it closely ... it momentarily drops to 10 Watts, which is close to idle, while 800 MHz is correct for idle. As I stated in my previous post, dead idle should be about 2 Watts.

You have Process(es) and / or Service(s) running in the background which is preventing your CPU from achieving a true idle. You need to get your idle Watts down closer to just 2 Watts. Under the Performance Tab in Windows Task Manager, you should see CPU Utilization consistently under 3% in order to be at a low state of idle.

Most PC's have a clutter of "tray-trash" which are unnecessary startups left behind from software installers. Windows, by default...

camf2xu,

Core temperatures respond instantly to changes in load.

Intel’s specification for Digital Thermal Sensor (DTS) response time is 256 milliseconds, or about 1/4th of a second. Since Windows has dozens of Processes and Services running in the background, it’s normal to see rapid and random Core temperature fluctuations, especially during the first few minutes after startup.

Your screenshot shows that Power is running around 30 Watts, which indicates a light load. Dead idle is about 2 Watts. Since you stated that your screenshot is at idle, there's obviously something running in the background.

Open Windows Task Manager and look under the Performance Tab to see what's running.

Also, you might want to give this Sticky a read: Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

I didnt, but i tried running AI Suites 3 and doing the 5 step optimization and it put something ridiculous like 1.45 volts to my cpu (13% OC) and blue screened me, so i uninstalled it but i guess some settings stayed. I just reflashed bios (cuz im not super familiar with bios and where everythings located) after you pointed out im running a constant 4.2ghz .
started out like this

and back to 4.2ghz constant (headscratch emote)

I do have XMP enabled in bios, but that pertains to my ram correct?

If you're using Windows 10, look at the Startup Tab in Task Manager to see what's running. For Windows 7 type msconfig in Start to see the Startup Tab.
