Taking advantage of this wave of offers at the end of the year, many people will plan to buy a new computer that is convenient. However, it's easy for novices to overlook some details when choosing a machine, such as the "mute" we're going to mention today.
The noise of the laptop mainly comes from two aspects, one is the sound from the cooling fan inside the fuselage, and the other is the tapping sound from the keyboard. Fan heat dissipation, in order to the hardware emitted heat can be quickly discharged from the fuselage, to ensure the performance of the play, the fan in the heat dissipation of full horsepower, will make noise; the noise of the keyboard may be the most easy to ignore when you choose the machine, but also the most annoying point after the realization, when the click of the keyboard sound is incessant, the impact is not only yourself, your roommates, classmates, colleagues, will be affected by this.
Especially in a relatively quiet environment, such as a study room, a library, a conference room, if your computer makes noise, it is definitely not a decent thing, and you will die directly in full view of everyone, but if you have the idea of "as long as I am not embarrassed, the embarrassment is someone else", it is only when I did not say it!
So in order to be able to find a relatively quiet notebook product, I found hp star 14 high-performance thin and light book, this product has an outstanding appearance, there are a variety of body color matching, smooth streamline design with metal material body, fashion and take into account the texture at the same time, coupled with a relatively high cost performance, star 14 high performance thin and light book is highly sought after by the student party and new people in the workplace. Let's take a look at how well this product, which is very popular among young people, behaves in silence.
1. Brief introduction of the test model
The test model I got was an integrated version of the Star 14 high-performance thin and light book. In terms of internal heat dissipation, the Star 14 high-performance thin and light book adopts the heat dissipation specifications of dual fans, and the enhanced version of the three-phase motor and thinner fan blades effectively improve the air flow and reduce noise. In addition, the A/C surface of the Star 14 high-performance thin and light book is made of metal, and the relatively better thermal conductivity also assists in heat dissipation.
In terms of keyboard, the lateral utilization rate of the entire C-side is very good, the key spacing reaches 19mm, the phenomenon of mistact occurs basically when typing, and the left and right keys of the arrow keys are also normal size, which is convenient for the correction of the code word; the key travel is longer, the feel is soft, suitable for code words; the surface of the keycap is coated, the touch is relatively slippery and not easy to oil.
2. List of test methods
Test environment: Quiet studio
Fan noise test:
First test the number of decibels in the conference room, the number of decibels in standby state, and use this as a benchmark. Hp Star 14 high-performance thin and light book use groups are mostly college students or workplace white-collar workers, there are needs for learning and entertainment, and the use scenarios are mostly places with quieter environments, such as dormitories, study rooms, libraries and so on. In view of this, I will test the noise performance of this HP Star 14 high-performance thin and light book while watching online videos and games. Finally, the number of decibels under the single baking of the Stress FPU, that is, the CPU is fully loaded, can show the noise level of the Star 14 high performance thin and light book under extreme conditions.
Keyboard noise test:
Place the decibel in the middle of the left side of the fuselage, type a 30-word sentence with my normal force, repeat it five times, take a random photo to grab the number on the decibel and then take the average, comparing it with the decibel in the standby state tested before.
The computer volume is adjusted to 0 during the test.
3. Start the test
After opening the HP Star 14 high-performance thin and light book, the decibel count is about 41, and the fan noise in the standby state is minimal, and it can be said that no noise is felt.
Then open the B station, watch "Water Margin", the resolution selected 1080P, in order to be more in line with the actual use of the scene, after playing two consecutive episodes to record the number of decibels, the decibel number displayed by the decibel meter is roughly 41.8 ~ 42.5, and the noise level during standby is almost the same.
Then play the LOL game, the image quality is set to the highest, turn on anti-aliasing and character strokes, choose a battle to watch in the game, and turn on the decibel meter after almost 10 minutes, the decibel value is about 43.5, and the noise increase is also minimal.
Use the AIDA 64 Stress FPU mode to single-bake the CPU, and after 10 minutes, the decibel count is recorded, hovering around 45. The noise in the fully loaded state is basically only slightly improved when watching online videos and playing LOL.
Finally, we tested the keyboard typing sound, and the decibels of the 5 random recordings were: 42.6, 43.6, 40.9, 43.2, 40.4, with an average of 42.14.
4. Test summary
The HP Star 14 High Performance Thin and Light book has a decibel of about 41 DB during standby
When watching 1080P video online at Station B, the decibel is: about 42 basically flat
In the game, the decibel is: around 43.5 slightly up
The decibel under the Stress FPU single bake is: around 45 slightly rising
The average decibel when typing is: 42.14 slightly up
Through the test we can see that the star 14 high-performance thin and light fan noise reduction performance is still very good, watching videos, playing games basically will not have any additional noise, only 1 to 2 decibels higher than the noise during standby, even if sitting in front of the computer will not notice the noise of the fan, in the CPU full load of the limit of the noise is also very little; in addition, in the keyboard, the normal force of the keyboard will not have much impact on the people around.
Returning to the topic, hp star 14 high performance thin and light book in terms of muting performance is good, fully able to bring it into the study room, if used in the dormitory, it will not affect others. In addition, the cost performance of the Star 14 high-performance thin and light book is also quite good, take advantage of the year-end discount, take it home quickly!
