Temperatures and comfort, Battery Life

Max CPU load

In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

Average core frequency (base frequency + X); CPU temp.

AMD Ryzen 7 7735HS (35W TDP)	0:02 – 0:10 sec	0:15 – 0:30 sec	10:00 – 15:00 min
MSI Bravo 15 C7U	3.64 GHz @ 72°C @ 65W	3.74 GHz @ 78°C @ 65W	3.75 GHz @ 87°C @ 65W
MSI Bravo 15 C7U Max Fans	3.77 GHz @ 65°C @ 65W	3.76 GHz @ 71°C @ 65W	3.77 GHz @ 84°C @ 65W
MSI Bravo 15 C7V	3.75 GHz @ 81°C @ 65W	3.74 GHz @ 84°C @ 65W	3.75 GHz @ 84°C @ 65W
Acer Nitro 5 (AN515-47)	3.94 GHz @ 73°C @ 75W	3.86 GHz @ 77°C @ 70W	3.87 GHz @ 85°C @ 70W

The MSI Bravo 15 C7U performs almost the same as the Bravo 15 C7V in terms of CPU clock and power limits. The Acer Nitro 5 (AN515-47) is doing a bit better job here but the MSI device is very close to its competitor. The CPU frequencies are always higher than the base clock and cooling can maintain ~65W which is a good score, given the fact that the Ryzen chip has a base TDP of 35W. You can also use the Cooler Boost function which will ramp up the fan to their max RPM speed. This will decrease the temperatures, but the noise levels are going to be higher. In Auto mode, the fans are spinning at around 4500 RPM. With Cooler Boost On, the rotation speed is ~ 5700 and ~ 5450 RPM for Fan 1 and Fan 2 respectively.

Real-life gaming

NVIDIA GeForce RTX 3050 6GB	GPU frequency/ Core temp (after 2 min)	GPU frequency/ Core temp (after 30 min)
MSI Bravo 15 C7U	1798 MHz @ 71°C @ 75W	1782 MHz @ 73°C @ 75W
MSI Bravo 15 C7U Max Fans	1824 MHz @ 63°C @ 75W	1814 MHz @ 67°C @ 75W
Acer Swift X 14 (SFX14-71G)	1484 MHz @ 72°C @ 50W	1481 MHz @ 75°C @ 50W
Lenovo Yoga Pro 7 (14″, 2023)	1718 MHz @ 72°C @ 58W	1714 MHz @ 74°C @ 58W

The 6GB version of the RTX 3050 isn’t a very popular video card and we have tested just three machines with this graphics chip up to date. We like what we see, the cooling can maintain a stable 75W TGP and a bit under 1800MHz core clock. Also, a 73°C GPU temperature after more than half an hour of gaming is a good result. You can activate the Cooler Boost mode but given the slight bump of the frequencies, it’s not worth it (at least for us) considering the increased noise.

Gaming comfort

When the machine is under heavy load, the center of the keyboard is getting hot. The thermals around the WASD section and the palm rest area are normal so you can use the machine for gaming comfortably. When the CPU temp is under ~55°C, the two fans aren’t spinning and the laptop is dead silent in this mode. Despite that the fans are working hard to cool down the internals during gaming or maybe video rendering, they aren’t too noisy even at max speed (well, not silent at all but the noise levels are kind of normal for a gaming laptop).

Battery

Now, we conduct the battery tests with the Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. This device features a 53.5Wh battery unit. It lasts for 7 hours and 42 minutes of Web browsing, or 7 hours and 9 minutes of video playback.
