(ChinaIT.com News) Since the beginning of summer, many places across the country have issued high temperature warnings one after another, and some areas even experienced extremely hot weather of 40°C.
In this high-temperature environment, many electronic devices will be affected, especially business office laptops, because they often need to face various complex usage scenarios. For example, when telecom engineers debug base station signals outdoors, or when home decoration designers discuss decoration plans with owners in rooms without air conditioning, they may face using laptops in a high-temperature environment of 40°C.PConline specifically testedThe performance of HP Z66 in high temperature environment.
In order to adapt to the use of notebook computers by business users in complex scenarios, business notebooks usually undergo rigorous tests such as high temperature, high humidity, high altitude, drop, and vibration.As the all-around king of business notebooks, HP Z66 has excellent performance in terms of portability, expandability, after-sales service, durability and adaptability, and provides users with a more comprehensive and efficient office experience among products at the same price.
In the previous evaluation, the CPU core temperature of the HP Z66 6th-generation Ryzen Edition is stable at around 77°C when the processor is fully loaded, and the overall power consumption is stable at 25 watts, which is 10 watts higher than the basic power consumption of 15 watts. This shows that Zhan 66 has excellent heat dissipation performance, can give full play to the performance of core hardware, and provide strong and stable performance output under daily office needs.
Zhan 66’s excellent heat dissipation system not only brings better performance release, but also brings a quieter user experience.In the office environment, we tested and found that the ambient noise was between 40 and 50 decibels, while the fan noise was only 40.9 decibels when the Zhan 66 6th-generation Ryzen Edition was fully loaded. In other words, in an office environment, even if the computer is working at full capacity, we can hardly hear the running sound of the Zhan 66 6th-generation Ryzen Edition.
At the same time, HP Zhan 66 has passed 19 military standard tests, and we have conducted a number of extreme tests on it, such as 138 kg football shot impact test, minus 10 ℃ ice rink extreme cold challenge, construction site dust harsh environment challenge, 110 kg trample challenge, etc. With its excellent performance stability, the HP Z66 can maintain stable operation in these extreme tests. So in the face of the high temperature of 40°C this summer, how will the HP and 66 perform? Next, we will meet today’s challenge.
How hot is it outside at 40°C?
Really heated up!
↑The ice cubes melted quickly
At noon at 40°C, in the high-rise office park, the reinforced concrete walls without vegetation reflect the energy of the sun, making people feel like they are in a baking oven. There didn’t seem to be any movement in the air, but the sultry atmosphere filled the surroundings, making it suffocating.
The outdoor bottom surface temperature is as high as 61.2°C
If you stay in this environment for a few minutes, you will start to feel the sweat pouring out of your body. Chocolate, popsicles melt quickly! Using an infrared thermal imager to measure the ground temperature, it was as high as 61.2°C!
40℃+environment
Zhan 66 is not only stable, but also fully released in performance
In the outdoor environment of 40°C + direct sunlight, let’s first take a look at the performance of Zhan 66 in such a high temperature environment. Because there is no way to connect to the power supply outdoors, we use PCmark10 to simulate daily office applications in the battery high-performance mode, and use the final score to compare and intuitively see the performance difference of the Zhan 66 at 40°C+ outdoors and 28°C indoors.
From the actual running score data, we can see that the PCmark score of the HP War 66 in a 40°C direct sunlight environment is at the same level as the score in an office environment of 28°C. This shows that the HP War 66 has better heat dissipation performance and higher processor performance. It can still provide stable daily office performance in a high temperature environment.
Video conferencing under the scorching sun at 40°C:
Mobile phone has overheated warning, Zhan 66 has no pressure
When using a mobile phone or computer for video conferencing, real-time video and audio codec processing and a large amount of network data transmission will take up a lot of computing resources, which will increase the heat generation of the device. Even in an air-conditioned room, using a mobile phone for video conferencing will also be hot. So what happens when using a Zhan 66 and a mobile phone for video conferencing in an outdoor high temperature environment of 40°C?
The Zhan 66 still maintains a stable video conference, and its CPU core temperature is stable at around 64°C, which is far from reaching the overheating protection temperature of 90°C~105°C. Therefore, when conducting video conferencing, laptops like Zhan 66 have better stability, and mobile phones will encounter problems of heating and rapid power loss. Therefore, many business users pay more and more attention to the video conferencing capabilities of laptops when purchasing computers.

Exposure to the 54°C high temperature challenge in the car
In the hot weather of summer, the temperature inside the car will rapidly rise to extremely dangerously high temperatures under the action of the sun. Due to the accumulation of heat in the confined space, various materials in the car will produce heat absorption effects. After an hour of exposure to the sun at noon, the temperature inside the car reached 52°C. In such an extreme environment, we conducted a PCmark test against the Zhan 66 again to see if the Zhan 66 can maintain its full performance after being raised from 40°C to 50°C.
After turning on the machine and standing in the car at 52°C for 10 minutes
The CPU temperature is stable at 56°C
Before the PCmark test, we first turned on the Zhan 66 and placed it in the car at 52°C. After standing for 10 minutes, when the CPU temperature stabilized, we turned on the PCmark to enter the test program.
The temperature inside the car rose to 54°C
War 66 runs stably
During the test, we could see through the car windowThe temperature inside the car rose to 54°C. In such an extreme environment, the CPU temperature of Zhan 66 also reached 75°C, which still did not exceed the overheating protection temperature. There was no problem in running various tests of PCmark.
54℃ high temperature environment
The performance of Zhan 66 is still fully released
In the car at 54°C+, Zhan 66 performed PCmark for about 20 minutes. During the operation, the whole machine remained stable, and the final score was consistent with the above test results at 28°C and 40°C. This shows thatZhan 66 can still provide complete office application performance in an extremely high temperature environment of 50°C+. And after the PCmark test, the CPU core temperature of Zhan 66 quickly dropped from 75°C to 59°C in less than 1 minute, while the ambient temperature remained stable at 54°C.
It can be seen that the power consumption control, heat dissipation design and CPU energy efficiency of Zhan 66 are relatively excellent.

How to maintain stability in a high temperature environment of 40°C
First of all, on the radiator, it can be seen through disassembly that it uses a double copper tube radiator. For a 15W low-power processor, a single copper tube design is sufficient, whileZhan 66 chose double copper tubes, which have a larger surface area and provide more opportunities for contact with air. This can speed up the transfer and dissipation of heat, thus improving the cooling efficiency.
Secondly, in terms of body material, the HP Z66 uses an all-metal body. Compared with ordinary plastic materials, metal has better thermal conductivity. We put an equal amount of candles in a plastic spoon and a metal spoon, and put them together on a constant temperature heating pad at 70°C. Soon the paraffin in the metal spoon has gradually melted, while the paraffin in the plastic spoon is still solid.
Through the thermal imager, it can be seen more accurately that the temperature of the metal spoon is significantly higher than that of the plastic spoon, which shows that the metal material has better thermal conductivity and can conduct the heat inside the computer body more efficiently, soZhan 66 metal fuselage can help the heat inside the fuselage to dissipate faster and ensure the stable operation of the hardware.
At the same time, the layout of the cooling system inside the computer is also very important. Reasonable air circulation path and radiator location arrangement can ensure that the heat is conducted from the heat source to the radiator as soon as possible, and can be discharged from the inside of the fuselage smoothly.A dense heat dissipation hole is opened in the key heat dissipation area of the bottom of the HP Z66 fuselage, so that the cooling fan can introduce the surrounding cold air into the fuselage and discharge the hot air.
In order to further improve the cooling performance, the HP Z66 also adopts intelligent temperature control technology. The internal temperature is monitored in real time by the sensor, and the system can automatically adjust the speed and power of the fan to ensure that the device is always kept within a safe operating temperature range. This intelligent temperature control technology can not only ensure the cooling effect, but also reduce noise and energy consumption.
High temperature is only one of the 19 military standards of the HP War 66. In addition, Zhan 66 has also passed many rigorous tests such as vibration, dust, sand, humidity, altitude, solar radiation, ESD (electrostatic discharge), low temperature, sudden temperature change, functional shock, drop, explosive gas environment, freezing/thawing, mechanical shock, and workbench operation shock. Comprehensive tests and evaluations have been carried out in terms of computer durability, reliability, anti-interference, and adaptability to harsh environments. Products tested in this way can be guaranteed to work normally under various extreme conditions, and have excellent performance and stability.
Although such extreme conditions may not be encountered in daily office applications, computers that meet such standards can provide us with a safer, more stable, and more durable experience.
