Some netizens asked Xiaobian, how much is the CPU temperature normal? How much is the computer cpu temperature normal?
How much is the temperature of the computer CPU?
Under normal circumstances, according to Master Lu's tips cpu temperature, the maximum should not exceed 85 degrees, it is best to control the temperature below 75 degrees is considered safe. When the temperature exceeds 80 degrees, it is easy to cause the computer to crash or automatically shut down, etc., which is a poor heat dissipation of the computer. The problem that causes the computer to have a high temperature is generally a problem of heat dissipation. For example, the temperature of a typical laptop cpu is significantly higher than the cpu temperature of a desktop computer. Mainly because the notebook is affected by the small size. Here is a brief introduction to what causes the computer cpu temperature to be high.
One: ambient temperature
The cpu temperature has a lot to do with the ambient temperature, and it will be higher in summer. Generally, when the CPU is idle, the temperature is within 50°, it is less than 65° when it is busy, and it is normal within 75° when working at full speed. Therefore, we recommend that everyone's summer environment temperature is too high, and it is best not to open the computer for a long time. Affect the life of cpu; in winter, due to the low ambient temperature, we will find that the temperature of cpu is generally controlled at around 30 degrees. If the cpu temperature is too high, it will cause a restart or blue screen of death.
Two: cpu fan quality and host environment
If the quality of the cooling fan of the CPU is very poor, the slow rotation will seriously affect the heat dissipation of the CPU, resulting in a high CPU temperature. At the same time, if the design of the air duct of the host chassis is unreasonable, the internal heat can not be discharged in time, which will also lead to cpu. The temperature is very high. Therefore, it is recommended that when buying a computer, the chassis and cpu fan should also be considered.
Three: overclocking
If the computer needs overclocking, it needs to increase the working voltage of the CPU. When the working voltage is increased, it will definitely cause the power consumption to increase, and the heat is naturally increased. Once the heat and heat are balanced, the temperature will no longer rise. The heat is determined by the power of the CPU, and the power is proportional to the voltage. Therefore, to control the temperature, the core voltage of the CPU must be controlled. However, if the voltage is too low, it will be unstable. This is especially true when the overclocking range is large. Many times when the CPU temperature does not reach the critical value, the system restarts with a blue screen. At this time, the culprit affecting the stability of the system is not the temperature but the voltage. So how to set the voltage in the extreme overclocking is very important, set high, the radiator can not stand, set low, CPU can not stand, so the general editor does not recommend everyone to use overclocking technology.
Through the above detailed introduction, how much is the cpu temperature normal? This problem is related to many factors. Xiao Bian suggested that when you use the computer, don't use it for too long, and the computer needs rest. In this way, the CPU will not be prone to high temperatures or damage. .
Q: What does NiMH stand for?
A: The material is Nickel Metal Hydride (NiMH) which has many advantages over other battery construction materials.
Q: What is meant by battery memory?
A: Older generation and batteries with other chemical make-up were subject to a memory effect. This is when a battery must be fully drained before recharge or their capacity is reduced. The New Generation of NIMH batteries do not develop a memory effect and can be recharged at anytime during usage cycle. When uncertain about battery charge level or condition, recharge it.
Q: What is the mAh rating mean?
A: This is a rating of energy storage capacity mAh = [milli-ampere hours". So if you are comparing batteries to a AA with a 2000 mAh rating, it will have twice the capacity of a 1000 mAh rating.
Q: What is the best application for NiMH batteries?
A: Most all applications where there is a high energy consumption and demand, is where NiMH belongs. The most popular applications are digital cameras, flashlights, and toys. If you find yourself constantly buying alkaline batteries for an application, then you should consider using rechargeable NiMH.
Q: How many times can a NiMH battery be recharged?
A: Lower capacity rechargeable AA batteries of 1700 up to 2000mAh can be recharged up to 1000 times in overnight slow charge mode, while 2100 to 2400 mAh rechargeable batteries can be recharged up to 600 to 800 times in overnight slow charge mode.
The new higher capacity AA 2500 mAh rechargeable batteries have greater power capacity, but they can only be recharged approx 500 times in the overnight mode. Capacity improvement or quick charging will always decrease the number of cycles. Every cell available on the market above 2100 mAh will have below 1000 charge cycles.
Q: What applications are not good places to use NiMH batteries?
A: Any situation where the battery is not used within a 30 day period or low energy draw devices, for example smoke alarms, emergency flashlights, clocks, TV remotes, etc.
Q: Why won`t NiMH batteries work in some applications such as smoke alarms?
A: NiMH batteries self discharge about 1% per day so if used in a low energy consummation or stand-by device, the battery will only last about 90 days before requiring recharge.
Q: Can I use a higher rated mAh battery in my electronic device (i.e. 1800mAh vs. 2000mAh)?
A: Yes, the mAh rating will give you longer run times between recharges. The higher rated mAh of a battery has no effect on electronic devices other than they allow longer term use.
Q: Why are AA and AAA batteries rated at 1.2 volts and alkaline batteries rated at 1.5 volts?
A: In fact, over the course of their discharge, alkaline batteries actually average about 1.2 volts. The main difference is that an alkaline battery starts at 1.5 volts and gradually drops to less than 1.0 volts. NiMH batteries stay at about 1.2 volts for almost 80% of their discharge cycle. Once alkaline batteries discharge to 50% capacity, it will be delivering a lower voltage than a NiMH battery.
Q: What you NEVER want to do with replaceable batteries?
A:
- Never mix batteries from different manufacturers
- Never mix batteries of different capacities
- Never mix batteries of different chemistries, i.e. NiCd, NiMH, Lithium, etc.
- Never DROP the battery if you can help it as NiMH batteries damage internally quite easily
- Never store NiMH in the refrigerator
- Never expose to extreme heat
Q: Do NiMH batteries lose capacity over time?
A: Yes, but nothing drastic. About 10 to 15% of the battery mAh capacity will be lost at the 400 to 800 recharge level. This will vary greatly because of battery and charger quality, along with how the consumer treats their batteries.
