How much do you know about CPU temperatures?
Do you know how to monitor CPU temperature? How to keep the temperature from rising? Learn to monitor, learn to cool down, and give your CPU a good working environment!
The CPU is the central processing unit. Without a network card, we can tolerate it, and without a sound card, we can continue to use it. And without the CPU, that's really nothing. However, the CPU generates a lot of heat and higher temperatures when it runs for a long time, and all this is hidden under your Windows desktop unknowable things. Now, what you need to know is the operating temperature of the CPU, from many aspects, to understand the environment in which the CPU operates, to ensure its health, and in this way, to ensure the health of the PC as a whole.
I. Temperature is critical
Early CPUs, whether Intel or AMD, have no internal temperature monitoring capabilities, and for the most part, they rely on just a thermistor inside the motherboard's CPU socket to monitor CPU temperature. The thermistor is a contact temperature measurement element, if the thermistor is not in close enough contact with the microprocessor, the heat from the microprocessor can not be effectively transmitted to, the measured temperature will be a large error. At the same time, the core of the microprocessor emits heat from the chip package to the external heat dissipation, the microprocessor surface temperature and the core temperature of the temperature difference between about 15 degrees to 30 degrees, while due to the different forms of the chip package, as well as different ambient temperatures, and let the real CPU temperature is difficult to determine.
Nowadays, new CPUs have integrated thermal diodes inside, such as Intel's Intel Pentium4, Pentium D, Core 2 Duo... processors; AMD's Athlon XP, Sempron, Athlon 64, and so on. In this way, real-time temperature monitoring can be achieved either through the BIOS or under the Windwos desktop, and the values are relatively much more accurate.
The CPU running temperature is a very delicate matter, and many PC crash and damage failures are closely related to CPU overheating. Therefore, real-time monitoring of the CPU running temperature is very necessary, although nowadays the CPU has overheating protection, but the mechanism of overheating protection is to shut down the computer, cut off the power supply, which is not something you are willing to accept in the use of non-stop shutdown how to use?
II. How to monitor CPU temperature?
The way to check the temperature in the BIOS is very simple. When you turn on your computer, press the "Del" or "F1" key to enter the BIOS according to the prompts, and you can find a program called "Hardware Monitor" or "F1" in the main BIOS interface. Hardware Monitor" or "PC Health" option in the main BIOS interface, there is also a setting for "Power--Hardware Monitor". Monitor", where you can see the no-load temperature of the CPU. Why is it called no-load temperature? When the BIOS drives the computer to do a self-test, the CPU doesn't do much work, so the temperature is only indicative.
The biggest use for viewing CPU temperatures under BIOS is to check that the CPU is running well at idle. With a cooler not installed, or with no silicone grease applied, CPU temperatures can climb quickly in a very short period of time. Temperatures that climb above 60 degrees in less than 5 minutes can generally be judged to be existential, as most CPUs usually run at around 50 degrees up and down at idle, and above 60 degrees is more dangerous.
In Windows, you now have the option of software such as Z Weapon, Evrest, and others to monitor temperatures. In addition, many name-brand motherboards from major manufacturers come with functional software for temperature monitoring on a random CD-ROM, through which you can find out the operating temperature of the CPU under system operation.
Three. Understand the CPU temperature value to protect the love machine
After the full range of CPU temperature monitoring, you need to check the heat sink, silicone grease, but you should also understand one thing - the normal operating temperature range of the CPU, long-term let the CPU in a higher temperature environment, although it will not be It's not going to cause too many problems, but it's going to shorten the life of the CPU considerably, so you need to know more than just a little bit about it.
Here are some normal ranges for CPU temperatures that I found online:
AMD processors:
AMD Althon, Althon Opteron, Duron, and Sempron series
AMD Athlon XP 1.33GHz+ 90 degrees
AMD Athlon XP T-Bred upto 2100+ 90 degrees
AMD Athlon XP T-Bred over 2100+ 85 degrees
AMD Athlon XP Barton 85 degrees
AMD Athlon 64 70 degrees
AMD Athlon 64 (Socket 939, 1.4 volts) 65 degrees
AMD Athlon 64 FX 70 degrees
AMD Athlon 64 X2 71 degrees
AMD Sempron (T-bred/Barton core) 90 degrees
AMD Sempron ( Paris core) 70 degrees
Intel processors:
Intel Pentium 4: 64 - 78 degrees
Note: The P4 will automatically downclock when it overheats, there is no definitive indicator, and theoretically it will never overheat.
Intel Pentium D (Dual-Core)
Intel Pentium D 820 (2.8GHz) 63 degrees
Intel Pentium D 830 & 840 (3.0 - 3.2GHz) 69.8 degrees
A few of the author's own computers:
Intel Core 2 Duo E4300, with temperatures between 30 and 50 degrees, depending on how many tasks are running.
Intel Core 2 Duo T8100, with temperatures between 40-60 degrees, depending on how many tasks are running.
Note: These temperature values do not mean that exceeding them will burn the CPU, but working below this temperature is certainly the safest. You can think of it this way: a refrigerator has its operating temperature settings, and generally manufacturers give recommended values to keep it cool. This list of values has a similar meaning - keep your CPU running at or below its normal operating temperature as much as possible to better protect your device.
