MSI GS66 Stealth 10SGS Laptop Review: Core i7 or Core i9?
The cooling solution consists of two ~50 mm fans and a smaller ~40 mm one with seven heat pipes between them. Fan noise will always be present at about 30 to 30.9 dB(A) no matter the setting or onscreen load even if on the preset MSI “Silent” power profile. Though audible, we don’t find this to be bothersome when browsing or video streaming. Still, we recommend using the laptop in Power Saver or Silent mode if not gaming or else the fans will pulse frequently.
Speaking of fan pulse, our GS66 10SGS is able to remain quieter for longer than the GS66 10SFS before plateauing at the same final decibel reading. For example, fan noise when running the first benchmark scene of 3DMark 06 would top out at 53 dB(A) on the 10SFS while the 10SGS would return a lower fan noise of 39.5 dB(A). When considering the higher Turbo Boost potential of the Core i9 in the 10SGS, the results make sense. When running Witcher 3, fan noise would stabilize at 48 dB(A) on both laptops. Overall results are on par with the GS66 despite the thicker and heavier build of the GS66.
Fan noise tops out at about 53 dB(A) when under more extreme loads like Prime95 and FurMark. If Cooler Boost is enabled, fan noise will increase to a steady 59.4 dB(A). We prefer to keep Cooler Boost off when gaming as it will not boost performance by all that much relative to the extreme increase in fan noise.
