    While playing games I noticed I would get constant periodic stuttering due to my CPU reaching my throttlestop alarm temp and switching profiles to lower clock speeds.

    After a little investigation I discovered that only one of my cores, core 0, was spiking into the upper 90s while the rest of my cores were holding steady in the 80s. (i set the affinity for the game i was playing to 2-15 to rule it out).

    Here you can see core 0 on top and core 7 on bottom. they are within a few degrees of each other until there is a temperature spike on core 0 every 30 seconds or so.

    This tells me that there is a process running on core 0 exclusively that is loading the CPU every 30 seconds and causing the temps to spike and thermal throttling the machine.

    I did some more digging with windows ADK and discovered that OmenCap.exe was the culprit. Its loading my CPU on core 0 to nearly 100% every 30 seconds.

    OmenCap.exe is loaded by OMEN command center to display CPU and GPU temps. You can disable it by going into your services and disabling "HP OMEN HSA service". Command center wont be able to display your temps but the fan curve will still work properly (i think the fans get their temp info from the bios).

    After disabling this service all my cores stay within a few degrees of each other and I have no more thermal throttling.

    Hmm. What happens if you reenable the service?

    I take it you had the same problem?

    Spikes come back.

    I also noticed that display fusion and "windows 10 firewall control" were causing similar, but smaller, spikes. My theory is that when they all happened to fire at once I would get the highest temp spikes causing me to throttle.

    Nothing i did could get rid of the display fusion spikes so i uninstalled it but windows 10 firewall control has a "low cpu" option.

    Also, if you use msi afterburner it uses less cpu cycles if you disable low level monitoring.

    I probably do however I don't have the level of knowledge you do here. I just finished a thermal repaste to Thermal Grizzly Kryonaut and HOLY MOLY! I ran 3DMARK Time spy and gained almost 1000 points just stock everything but the repaste. 800+ points in Cinabench just now. NEVER went past 78*c on the CPU!!!!! She's already running better. Now to run the Division 2 and test some more. I'm speechless at the difference with the good thermal paste. I appreciate the tips and the inspiration!

    Also I'm not seeing any spikes at all now after the repaste through TIme Spy, Cinabench, and FIrst Strike so far.
