? In my configuration here, Ive got the Intel i7 8750H CPU with Nvidia GTX 1050 Ti Max Q. Graphics, so expect different results. With the 1050 version., Thermal testing was completed with an ambient room temperature of 23 degrees Celsius so expect warmer temperatures in a warmer environment. Also keep in mind. There are heatpipes shared between processor and graphics, so a change in one component may affect the other.. Its also worth noting that both the CPU and GPU are cooled by just one fan, so lets see how well it does., Starting at the bottom of the graph at idle. The temperatures are warmer than average shown by the light blue bars.. The gaming tests were done with Watch Dogs 2 as I find that to use a good combination of CPU and GPU. Continuing up in the green bar. Both the CPU and GPU reach 91 degrees celsius with the fans at default speeds. By enabling cooler boost mode to max out the fans shown by the yellow bar temperatures, drop back significantly. With the fans back at stock speed, but with a 0.120v undervolt applied to the Cpu shown in orange its a little cooler compared to gaming at stock in the green bar., When we combine the CPU undervolt with MSIs cooler boost mode in the red bar, we see the coolest temperatures while gaming, with both the CPU and graphics in the mid 70s. A nice improvement., The stress tests were done by running Aida64 and the Heaven benchmark at the same time, in order to attempt to fully utilize both the processor and graphics.

Continuing up in the graph with the dark red bar, I was seeing the combined CPU and GPU Load limit the CPU to a 35 watt TDP, and there was both thermal and power limit, throttling taking place on the CPU and thermal throttling on the GPU., With cooler boost mode enabled, with the stress tests running shown by the pink bar theres. A big improvement to the temperatures.: This stops thermal throttling, but power limit throttling was still present.. The CPU undervolt, with the fans at stock speeds shown in purple wasnt enough to cool the components and then, with the undervolt and coolerboost mode, enabled together at the top of the graph in the dark blue bar. We get a little improvement in CPU temperature.. These are the average clock speeds for the same tests just shown. Again starting down the bottom. We can see that CPU clock speeds raise the most when the CPU undervolt is applied shown by the orange and red bars, as this helps reduce the power limit. Throttling. Its worth, noting, though, that in all of these combined CPU and GPU tests, the 8750H wasnt able to hit the full 3.9GHz turbo speed, although it does get very close in gaming, with the 0.120v undervolt applied to the CPU, with the fans in coolerboost mode shown By the red bar., We also see improvements to the graphics clock speed when we turn coolerboost mode on, and this is because the graphics were often experiencing thermal throttling with the single fan at default.

Speeds.. These are the clock speeds I got while just running CPU. Only stress tests without any GPU load. Without the undervolt, the power limit throttling, was preventing a CPU only stress test from reaching the 3.9GHz turbo speed of the 8750H. But this was possible once undervolted shown by the green bar. To demonstrate how this translates into performance. Ive got some Cinebench CPU benchmarks here with the older 7th gen i7 7700HQ, just down the bottom for comparison., While the CPU clock speeds were closer together in the previous graph, the Cinebench scores between stock and undervolted are quite different.. This is because, while running cinebench, the CPU TDP was not passing 35 watts, while under the Aida64 stress test, it was running at 45. Watts. Here are the GPU, only clock speeds, while under a graphical, only stress test and were seeing an improvement of around 126MHz with a manual 200MHz overclock applied. It didnt get further due to power limits.. So how do these performance boosts actually translate into games? Ive tested with the exact same Windows, Nvidia and game updates installed, the only changes were the ones listed. Here. Far Cry 5 was tested using the built in benchmark. The average frame rates at ultra settings were 5.6 better compared to stock speeds, and there was also a little improvement to the 1 low results at other setting levels, though, results will of course, vary between games.. As for the external temperatures, where youll actually be putting your hands at idle, it was in the low to mid 30s around the keyboard.

. While gaming, the middle of the keyboard, gets to 50 degrees and up to 56 right up. The back. Very similar results with the stress tests running and then a fair bit cooler once we enable cooler boost mode to max out the fans, but lets find out just how loud this gets. At idle. The fans were still slightly audible., While gaming and under stress test it was about the same, and this was significantly quieter than most other gaming laptops Ive tested, but as we saw before, the temperatures are suffering as a result, with thermal throttling taking place. With coolerboost mode Enabled and the single fan maxed out it gets quite loud, though, as we saw earlier, this improves the temperatures quite a lot. Overall, the performance was acceptable once you boost the fans and apply a CPU undervolt, despite the single fan to keep it all cool. Its. Definitely the i7 8750H thats getting the temperatures up there. I think the 1050 Ti Max Q. Graphics are just suffering due to the shared heatpipes. Im, not sure why MSI went with quieter fans at the expense of thermal throttling out of the box. Looking in the Dragon Center software, it looks like the fan is configured to only reach 55., Although, as you heard, it was quieter than most other laptops, Ive tested, while gaming as a result, however, Id prefer it to be a little louder and not throttle or run As hot at least youve got the option of adjusting the fans for yourself, though, so you can improve this at the expense of more noise.

, As this is the highest specced version of the GF63 laptop. The results shown here should be a worst case. Scenario., The 8RC model is the same, but has 1050 graphics instead, so it may run a little cooler as its not quite as powerful its hard to say, though, as most of the heat seems to be from the 8750H CPU.. These differences in performance shown arent hard and fast rules. There are different factors which will vary results, primarily the temperature of the room, youre running in application of thermal paste, and even the specific hardware which comes down to the silicon lottery.. You may not be able to undervolt or overclock your hardware the same as me. It depends on the chip and its specific power requirements, so dont just blindly copy my settings and do some testing to find out where your stable point is for best results.. While you could improve the temperatures by swapping out the thermal paste thats, not something I can test in a review unit.. If I go ahead and remove the stock thermal paste and replace my own, I can't put the old paste back, so the next reviewer would experience something different from what you'd actually see with the product and unknowingly report incorrect information due to what Ive, done. Undervolting and Raising the fan, speed, on the other hand, arent physically intrusive and as we've seen, it did improve temperatures and gaming performance a little in this particular unit.

With no downside once youve got a stable undervolt.. Let me know how much of a performance boost youve found by undervolting your hardware and what you thought of the improvements here and dont forget to subscribe for the full review of the MSI GF63 gaming laptop as well as future tech.
