This $30, 90W option is lightweight, small, and is working well for me so far, and will keep you topped off during a day of work. The 180W AC adapter that comes with the laptop is large and heavy. You can use these to make sure your laptop is stable over time.Įxample thermals change by someone else who did this on Fortnite, unverified)
Intel XTU has built-in CPU, memory, and graphics stress tests. You can use a utility called PowerPlanSwitcher for two-click power plan changes from the taskbar. I’ve been switching to the processor-limited plan for daily use when I’m not editing or encoding video. Now, you can choose this power profile when you’re doing things that require GPU and not CPU, or when you just want super quiet, cool performance, like when the computer is on your lap. Change “Maximum processor state” to 98% for both “On battery” and “Plugged in”. Scroll down to “Processor power management”. Select “Balanced” to start from, and change Plan Settings. Very quiet and cool.Disable Intel Turbo Boost by setting max CPU to 98% (from 100%) CPU will max out at 2.09GHz instead of ~3.9GHz, but has full GPU performance. My tests are stable at -0.160V (I haven’t pushed it further). Undervolt the GPU using Intel XTU tuner (settings are locked, and are not accessible from MSI Afterburner)
There is noticeably-lower fan noise during normal use.The CPU continues to throttle from high temps at 100% load, but stays between 3.6-3.8 GHz.My tests are stable at -0.150V, but not at -0.160V.
Undervolt the Intel i7-8750H CPU using Intel Extreme Tuning Utility. If you’re OK tinkering with Windows tools, can you make the laptop run more efficiently (cooler/quieter), and set up a secondary power profile that makes it almost silent, while retaining all of the GPU power. MSI Stealth GS65 laptop owners will notice that they run hot, and the fan kicks in pretty aggressively (and loudly!).
