The heat dissipation can be said to be the second parameter (the first is the screen) that the strokes evaluation room. A computer has a poor heat dissipation. The experience in all aspects will decline.
According to my impression, starting with Intel’s eighth generation Core, the laptop with poor heat dissipation is very rare. Most products are sufficient for heat dissipation, and they will make choices in terms of performance and noise.
So how can we judge the cooling of our notebook?
Let’s briefly analyze today:
HP Star 13 Air
On the left side of the fuselage
Right side of the fuselage
Its configuration is as follows:
R7 5800U processor
16GB 3200MHz memory
512GB solid state hard disk
13.3 inch 2560 × 1600 resolution 100%SRGB color gamut 16:10 ratio IPS screen
Battery capacity 43WH
The body weighs 0.96kg
The current price is 5999 yuan
R5 version priced at 5399 yuan
Its advantages and disadvantages are as follows:
1. The fuselage is extremely light, three -sided magnesium aluminum alloy material
2. Good screen quality, high resolution+high brightness+high screen ratio
3. There are many choices for body color matching
Moonlight Silver Ceramic White Liquor Gold Rose Gold: Available
1. The uniformity of the keyboard backlight is average, and the boot keys is too close to the DEL key
2. Under the high load, the temperature on the left side of the keyboard is very high
3. The battery capacity is small
This laptop is not difficult to disassemble. After tearing up the two foot pads, remove the 5 screws of the D shell, you can remove the rear cover with the help of the suction cup.
Dual -channel 16GB DDR4 3200MHz memory, the memory cannot be upgraded.
The solid -state hard disk capacity of the test machine is 512GB. The Magic OEM model supports PCIE3.0 × 4 and NVME. If you have special needs, you can replace the solid -state hard disk.
1. The requirements for computer portability are extremely high
2. Users who like white or high -value notebooks
3. The requirements for gaming performance are not high
The biggest feature of Star 13 AIR is light. Many small -sized laptops on the market are actually very heavy. Star 13 Air uses a magnesium aluminum alloy body.
, It uses a DC lighting panel with a measured color gamut volume of 102.5%SRGB, color gamut coverage of 96.6%SRGB, average △ E is 1.38, maximum △ E is 6.17, and the measured maximum brightness is 456.1nits. question.
On the left side of the fuselage are HDMI2.0, USB3.2 Gen1 Type-A, full-featured Type-C (supporting PD charging), 3.5mm headset interface, and a USB3.2 Gen1 Type-A interface on the right.
It is worth mentioning that the A port on the whole body is folded design and needs to be adapted.
, PCMARK10 endurance test scores are 11 hours and 10 minutes. (Scene: Modern Office)
Its full -loaded decibel value is 41.5DB, which is relatively quiet.
Star 13 AIR is a pure nuclear laptop. It is also the most conscience product in the HP Star series in recent years. The R5 version is cost -effective.
Now that it has risen
So if you care more about the portability of the fuselage and want a white notebook, then this computer is very suitable for you.
But if you have requirements for gaming performance, then it is not suitable for you.
【Pig King’s Conscience Conclusion】
The picture above shows the real shot of the HP Star 13 AIR, a combination of a single air fan single thermal tube.
Room temperature at 25 ℃
BIOS version: F.01
For the light and thin copy without independent display, we use the Stress CPU with a lower load for pressure testing.
In the full load, the CPU temperature is up to 77.8 ° C, and finally stabilizes at 72.1 ° C, the power consumption is 15W, and the frequency is 2.95GHz.
Left slide look at the back temperature on the back
Baked back temperature
The surface temperature is as shown in the figure above. The keyboard keycap is up to 47.9 ° C at the left position of the keyboard. The left wrist holds 34.1 ° C, and the back is up to 55.3 ° C.
In general, the heat dissipation performance of Star 13 AIR is quite satisfactory, the core temperature is not high, and the surface high temperature area is also well controlled, but the core position of the CPU core is obvious.
If you simply look at the CPU temperature, the heat dissipation of HP Star 13 AIR can be said to be quite good. The full load is only 72.1 ° C, which is cooler than the 95%notebook.
But in fact, the cost of low core temperature is that the performance is conservative, and the power consumption of only 15W is enough for business office. Therefore, this computer is destined to not be suitable for users who value performance.
Judging the heat dissipation of a computer, there are four aspects:
This is the easiest to judge and most important parameter. If the core temperature is extremely high, the computer will even be black -screen dead machines. Therefore, when looking at the evaluation, the core temperature in the full load state is critical.
In order to avoid overheating when the full load is full, some chickens manufacturers will limit the release of core performance, the performance is weak, the core fever is naturally low, and the restriction of performance is very common in creative design PCs.
Some computer core temperatures are very low, but the surface temperature is very high, so if the keyboard is not connected, it will affect the use experience.
The surface temperature contains “high temperature values” and “high temperature area”, and both need to be paid attention to.
Some manufacturers will use ultra -high -speed fans to increase ventilation efficiency. The temperature is indeed controlled, and the performance release is also good, but the noise collapse.
When the high load is running, the fan will inevitably have noise, but the noise noise with excellent heat dissipation, smaller decibel value, and poor noise control computers, sharp noise, high decibel value.
The perfect laptop computers of the above four points basically do not exist
You can judge and choose the right model based on your tolerance.
For example, when you are used to an external keyboard when you use your computer, the surface temperature does not matter.
Or you like to bring headphones when playing games, and the noise will not affect you. (Except for the dormitory))
For another example, if you are an ordinary office receiving email, the performance release is enough.
In addition to the four points mentioned above, the heat dissipation judgment also includes many details such as “maintenance convenience” and “thickness”. Only more professional practitioners can answer. Here I can only talk to everyone a brief talk.
All in all, the heat dissipation design is a science. As long as a computer is cooling, it should be a good computer worth buying.
