How to Check CPU Throttling in Windows 10 or Windows 11
Recent processors all have the ability to adjust the operating frequency to either decrease power consumption or make sure the processor does not overheat. That’s why for example Intel processors have a maximum junction temperature (Tj max) so that if this temperature is reached the processor can slow down (throttle) to cool things off and avoid damaging itself. That also explains why computers with the same processor, storage, and memory may have greatly different performance under load depending on their thermal design. I’m currently testing a fanless mini PC with an Intel Celeron N3150 Braswell processor, and yesterday I noticed the frequency would be stuck at 0.22 GHZ (yes, that’s 220 MHz) at all times, even when starting the web browser and loading long web pages. It was very slow, and I had a few “windows not responding” in the process. I checked the metal box temperature with an IR […]
