CPU tempreture and clocks jumping around, the same issue is in other software/monitors, had this issue over 6 month now, any suggestions on why this happens, does this indicates a dying tempreture sensor?

Sorry for the bad cropping on the GIF open it in a new tab

 
As noted above, fluctuating clock speeds is normal for a desktop environment with assorted WIndows background tasks and services starting/stopping randomly.

If you'd like to induce a constant load, CPU-Z has a 'bench' tab with an option labeled 'stress CPU' which, until stopped, will induce a relatively constant load across all cores; not as heavy a load as Prime95, but, a decent load that will raise temps to about the 'medium-heavy gaming level'... (a 9900K on a mainboard on most z-series mainboards would see all-core turbos of 4.7 GHz for 60-90 seconds or so, with reduced clocks thereafter, unless BIOS and/or Intel XTU tweaked with MCE enabled, power limits/boost duration limits disabled, etc....

Include system specs...CPU, GPU, motherboard, memory, CPU cooling, case and case fans at least.

Temps and clocks are supposed to move around and are considered normal CPU operation unless they exceed the stated Max specs for your particular processor.

If you're expecting a fixed CPU clock speed the only way you'll get that is to set a fixed CPU multiplier and disable CPU features like speed step.

Temps are entirely dependent on your cpu and case cooling choices...as long as your cpu is set to run stock voltages.
