Question CPU clock speed drops randomly to 400mhz for 5 seconds ?

Whether watching a youtube video on one tab and with no other programs open or playing games, every once in a while the CPU clock speeds drop to 400mhz from the 3500-4000 range.

I have had task manager open at the same time it happens and did not notice any programs acting strange.

My CPU is a Ryzen 5900HX (inside a Razer Blade 14) and I am using AMD APU Tuning Utility to thermal throttle at 73c (issues have started in the past few days and the tool was working fine for weeks). However, the clock speed drop also happens when it is around 60c.

Any ideas for causes or solutions?

Hi, I have exactly the same problem on my laptop with the same processor. So far, the issue has not been resolved, the problem occurs precisely under load in games. This is terribly annoying
