High CPU usage & temperature until Task Manager is opened

[qwertyk1d]

Hi everyone - got a weird one. My CPU temperature and usage is high until I open Task Manager when it drops down to normal temperatures. I've done the usual Malware check and nothing has shown up so I'm not sure its that.. I've also tried a third party process manager and nothing looks out of the ordinary.

Anyone else come across this before?

Personally I'd reinstall the OS sounds weird

Anything less drastic? Do you think its a rogue Windows process?

need lot more info than that.

are temps high at boot-up?
are you opening task manager right away after boot-up?

They seem normal then over a little time they climb up when I check them in NZXT CAM or HWMonitor. Then as soon as I open Task Manager, they drop down to 38-44 degrees at idle..
