Under AIDA64 CPU & GPU pressure test, the Intel i7-10750H is throttling down around 33%
The CPU package temperature is around 96℃±2℃, GPU temperature is around 73℃±2℃

These results are definitely not normal. We suspect that because the machine is an engineering sample, which may have a contact problem caused by bumps during transportation. We disassembled the machine and reinstalled the whole heatsink and re-applied the thermal grease with an industrial graded Xinyue 7921, then turned on the Cooler boost function.

The Intel 10th gen i7 does generate a huge amount of heat, the previous cooling system easily suppress the 8th and 9th generations’ i7. This problem does not only happen on laptop CPUs but also desktop CPUs. This is indeed the biggest pain point of Intel’s new generation of Coffee Lake CPUs. After the test, we thought MSI’s new Cooler Boost Infinity+ was not that efficient for the 10th generation until MSI switches the whole heatsink module to their latest version.

SUMMARY

As a gaming laptop, the MSI GS66 Stealth 10SE laptop has very powerful performance. The Intel Core i7-10750H processor is easy to deal with whether it is for gaming or creative needs. The Nvidia RTX 2060 graphics card has a good balance between performance and thermal control. It meets the performance requirements of various AAA game, but also has the support of Ray-Tracing technology. The 240Hz refresh rate IPS screen has good colour performance, and 3ms response time is also a great addition for e-sports players.

For laptop computers, it is usually difficult to have both size, performance and endurance together. In fact, MSI GS66 Stealth 10SE has made a good balance. Not only is it equipped with a 99.9Wh battery, but at 20mm, it’s not thick either. Under the battery life test, this gaming laptop will stand around 4 hours of in-game playing, while the daily work life is About 6 hours, it is basically consistent with its hardware specifications and battery size.

Of course, the Killer E3100 2.5Gb network card not only has strong performance but also supports Killer’s unique QoS function, which can prioritise gaming network data and reduces lag. The dual 2 watts Dynaudio sound effects also brings users an excellent sound experience

For heat dissipation, it is probably an unavoidable problem for thin and light laptops. The heat generated by the 10th gen i7 and i9 is terrifying, and this is not something that ordinary heat dissipation modules can solve. Just after our first bench feedback, MSI quickly responded and replaced the new version of their thermal module. This new version thermal module is currently built-into the on sales GS66 and WS66 workstations laptops. The heat dissipation performance is very good. For the latest stress test, please refer to our previous review article on WS66.

At present, the MSI GS66 gaming laptop has a variety of different hardware configurations. The processor range is from Core i7-10750H to Core i9-10980HK, the graphics card ranges from GTX 1660 Ti to RTX 2080 SUPER Max-Q, and the screen refresh rate ranges from 144Hz to 300Hz. We believe that users with different needs will find their favourite model.
