How to choose a computer CPU heatsink
With the coming of Summer , and the problem of computer heatstroke due to high temperature has also come. For some users, the host has been cleaned, silicone grease replaced and fan installed before, but as soon as the temperature rises, the CPU temperature remains high. Why?
Obviously, it should be the reason of CPU heatsink. What are the reasons why the performance of the CPU heatsink can not be brought into full play? This may be that some details are ignored when purchasing CPU heat sink, which leads to the above problems.
Nowadays, although the price of integrated water-cooled radiator has been greatly reduced, and it's easy for most user to get , air-cooling heatsink is still the mainly choice of . When users buy CPU radiators, in addition to the fan parameters, the number of heat pipes, the area of cooling fins and other parameters, what other details deserve attention?
The installation method impacts a lot:
There are two ways to install the CPU heatsink , metal clip and screw attachment.Metal clip is a fixed method that compresses the bottom of the heatsink and the top cover of the processor through the elasticity of the metal fastener. As long as it is installed correctly, this installation method can completely ensure the normal heat dissipation of the CPU. Otherwise, it may leads to poor contact between the radiator base and the CPU , and the heat dissipation effect is naturally poor.
The probability of errors in screw installation is relatively low. After long-term use, the pressure reduction caused by metal fatigue is also smaller than that of fasteners, which can be said to be a more reliable radiator installation method.
More fans doesn't mean better performance:
To improve the thermal performance, increasing the air volume is a good direction. The conventional approach is to use larger fans, increase the fan speed or increase the number of fans. However, the radiator itself is small and it is difficult to install a larger fan. If the fan speed is increased, the noise will also increase. The only feasible way is to increase the fan.
Actually , although the fan is added to improve the air volume, the bottleneck restricting the performance of the heatsink often lies in the number of heat pipes and the heat transfer efficiency of the base. If the heat cannot be transferred out fastly, it makes no sense no matter how large the air volume is. You will also face additional resonance, noise and other problems.
Base details also means:
In order to transmit the heat generated by the CPU quickly, it all depends on the base, so the heat absorption efficiency of the base is very important. As far as the base is concerned, the base includes heat pipe direct contact or metal base are common used in design.
Heat pipe direct contact design, because the heat pipe is in direct contact with the CPU shell, the heat dissipation efficiency is relatively high. If the manufacturing process is not good and multiple heat pipes at the bottom of the radiator are not flat enough, it will also seriously affect the heat dissipation effect.
Thermal solutions for every industry is very important as the power is gradually higher and higher, Sinda Thermal can provide varieties heatsinks and coolers which inlcuding aluminum extruded heatsink, high performance heatsink, copper heatsink, skived fin heatsink, and heat pipe heatsink. please contact us if you have any questions about thermal solution.
