Environmental noise: 25.0dB classroom learning (quiet mode) This round of test will simulate students using computers in class, running common software such as Office, online notes, social communication, browsers, etc., setting HP VICTUS Light and Shadow Wizard 8 to quiet mode, and setting the fan speed to automatic. After testing, the running noise of HP VICTUS Light and Shadow Wizard 8 in this state is only 30.7dB, which is completely lower than the allowable noise level of various teaching rooms in schools in the design specification, that is, the noise of ordinary classrooms/laboratories/computer classrooms/teachers' offices/lounges/conference rooms is ≤45dB, and HP VICTUS Light and Shadow Wizard 8 in silent mode is really quiet. Daily Recreation (Balance Mode) This round of test will simulate students' daily use of computers in the dormitory, such as watching 4K local videos and running mainstream games such as CS:GO, and set HP VICTUS Light and Shadow Wizard 8 to balance mode, and set the fan speed to automatic. After testing, the running noise of HP VICTUS Light and Shadow Wizard 8 is still maintained at 30.7dB when watching 4K local video, and there is no additional noise. However, when running the game CS:GO, the noise of the whole machine began to increase with the speed of the fan because of the need to mobilize the independent graphics card to ensure the game effect. The noise of a simple scene is about 33. 1dB, and that of a complex scene is about 35.5dB. The school dormitory belongs to an educational and cultural residential area, so it should be compared with the 1 standard in the noise standard, that is, the noise should be less than 55 dB during the day and 45 dB at night. Under this standard, the noise value generated by HP VICTUS Light and Shadow Wizard 8 running the game is within the normal range.
