Hey all!
An issue I've been noticing are these sudden drops in CPU utilization alongside GPU utilization from like 90ish% to 10ish% then back up. The result is several seconds of stuttering, where the audio/gameplay just stutters for a brief several seconds. After checking in the Intel Extreme Tuning Utility, it seems that these drops are being caused by thermal throttling. I checked with HWMonitor and the CPU core temperatures basically hit 100C all the time. However, this only happens when the computer is plugged in. I tested this by unplugging the laptop, setting the power plan to the best performance, and playing the same video game, and I don't see the same stutters. It reaches maybe 80C max at worst. I haven't overclocked anything, and, in fact, have been undervolting by -.128
Even on idle, while plugged in, my CPU is reaching mid 80Cs. However, once unplugged, it hovers around low 60Cs with the same best performance power plan. Is it typical for there to be a 20C difference between plugged/unplugged? Fans seem to be working afaik. My GPU temperature reaches max low 70C when plugged in, and is usually around mid 60Cs when gaming, so it doesn't seem to be the issue here.
Basically, in sum:
Ambient Temperature: 25C
Plugged in (Best Performance):
CPU temp (no gaming): 70-80C
CPU temp (gaming): 95-100C
Battery (Best Performance):
CPU temp (no gaming): 55-65C
CPU temp (gaming): 75-80C
Why it so different??
I also have a cooling pad coming in, but I just want to figure out what's going on. Because this wasn't a problem before and just started happening recently, I'm going to reapply thermal paste/clean out the fans and see how that goes.
