the normal value of p>cpu temperature is generally stable within the temperature rise of 3 degrees. In other words, the cpu's tolerance temperature is 65 degrees, and the cpu temperature is allowed to rise to 3 degrees according to the highest temperature of 35 degrees in summer. By analogy, if your ambient temperature is now 2 degrees, the cpu had better not exceed 5 degrees. The lower the temperature, the better. No matter how much you overclock, don't make your cpu more than 3 degrees above the ambient temperature. Now I want to add a few points: 1. The problem of temperature and voltage. The increase in temperature is due to the fact that the calorific value of U is greater than the heat output of radiator. Once the calorific value and heat output tend to be balanced, the temperature will not increase any more. The calorific value is determined by the power of U, and the power is directly proportional to the voltage. Therefore, to control the temperature, it is necessary to control the core voltage of CPU. But it's easier said than done. If the voltage is too low, it will cause instability, especially when the overclocking amplitude is large. Many times, when the CPU temperature doesn't reach the critical value at all, the blue screen will restart. At this time, the chief culprit affecting the stability of the system is not temperature but voltage. Therefore, how to set the voltage well is very important in extreme overclocking. If it is set high, the radiator will not stand; if it is set low, the U will not stand. 2. The temperature measurement methods of various motherboards are not the same. Even the motherboards of the same brand and model will have very different temperatures due to the distance difference between the temperature measurement probes and the CPU. Therefore, it is unscientific to say how much temperature is safe in general. I think it's enough to run super Pi or 3DMark under the condition of high room temperature in summer, as long as it passes stably, and you don't have to trust the temperature data of software testing too much. 3. What is stability? This has always been a hot topic that everyone likes to discuss. The computer is an electronic product, and the coordination of various components is extremely subtle. No one can say that my computer is absolutely stable, and stability is relative. Overclocking within a reasonable range can resist the catastrophic consequences that may be brought by most minor unstable factors; Overclocking at the extreme edge of the hardware, a tiny current fluctuation may bring a series of subsequent reactions, which may eventually turn your screen blue or black:) The question of how much frequency to quantify is stable is only for specific situations, and there is no formula to apply, so we can only rely on experience and personal practice. So here again remind some friends who ask "how much can my computer overclock", or try it yourself according to the scientific overclocking steps! Generally, you can know it by entering the BIOS. I recommend several CPU temperature control software to you, and you can understand the temperature changes. First, Waterfall Pro (download address: Sina Download Center) is an old-fashioned computer refrigeration software, which is small in size and powerful in function, and can effectively control the temperature rise of CPU, optimize CPU speed, and monitor CPU occupancy and power consumption. Second, CPUIdle CpuIdle (download address: Sina Download Center) can significantly reduce the running temperature of CPU, prolong its service life, and at the same time reduce the power consumption of CPU. Different from other energy-saving software, CpuIdle can still play an obvious role even in the case of overload work. SoftCooler II SoftCooler (download address: Sina Download Center) is a green chip cooling software, which has the advantages of occupying less system resources and memory space, and can be used directly after decompression without any setting. 4. VCool VCool (download address: Sina Download Center) is a cooling software specially tailored for AMD CPU. Moreover, it is a portable application, which is very simple to use, occupies less system resources, and has a good cooling effect on AMD CPU. V. CPU Cooling Saint Hand CPU Cooling Saint Hand (download address: Sina Download Center) is a compact CPU cooling software. The system kernel processing adopts assembly technology to directly optimize the CPU unit, which is suitable for all types of CPU products and plays a good role in optimizing and protecting the CPU.
