The guarantee is generally stable in the range of 30 degrees of temperature rise. In other words, the CPU's tolerance temperature of 65 degrees, according to the summer maximum of 35 degrees to calculate, it allows the CPU temperature rise to 30 degrees. By analogy, if your ambient temperature is now 20 degrees, the CPU is best not to exceed 50 degrees. The temperature is, of course, the lower the better. No matter how far you are overclocking, do not make your CPU higher than the ambient temperature of more than 30 degrees.
Now to add two points:
1. Temperature and voltage problems. The increase in temperature is due to the heat of U is greater than the heat of the radiator, once the heat and the thermal balance, the temperature will no longer rise. Calorific value is determined by U power, and the power is proportional to the voltage, so to control the temperature must control the core voltage of the CPU. However, it is easy to say that if the voltage is too low, it will cause instability, especially when the amplitude of overclocking is large. Most of the time the CPU temperature does not reach the critical value of the system on the blue screen, then the culprit affecting system stability is not the temperature but the voltage. So how to set a good voltage in the extreme overclocking is very important, set high, the radiator does not live, set low, U can't live.
2. A variety of motherboard temperature measurement methods are not the same, or even the same brand, model of the motherboard, due to the temperature sensor proximity to the CPU distance difference, will also result in a large difference in the temperature detected. Therefore, the general say how much the temperature is not completely scientific. I think in the summer high room temperature under the conditions of their own run a master or some 3D games, as long as the stability of the pass on it.
