CPU is about to burst! First look at these points when changing the radiator!

Many friends will be very worried about the heat dissipation of the computer in the summer. The processor temperature is even more worrying. Consider a more powerful heat sink? Do n’t you know the knowledge of these radiators before you go? Believe that Xiaobian, understand these, definitely make your shot more stable and ruthless.

Is copper better than aluminum? not that simple!

The material of the CPU heat sink is mainly copper and aluminum. Because of the specific heat capacity and density of the metal, copper absorbs heat and heat quickly, but it also heats up quickly, and aluminum is just the opposite. The high-frequency processor heat sink combines their advantages. The design uses a copper core on the bottom and aluminum heat sink fins. The effect is very good and worth choosing.

How to choose the wind direction?

There are two fan designs for CPU radiators. One is the traditional downward blowing method, which directly blows the bottom of the radiator and has a more compact structure. The side blowing method is that the fan is on the side of the radiator, and a larger fan and multiple fans can be used. However, heat must be quickly transferred to the fins. The multi-heat pipe method is generally used, which has a high cost and takes up a lot of space.

Blow down

Side blowing method

The choice of down-blowing or side-blowing mainly depends on the design of the chassis and the air duct. The small chassis has no choice, and direct blowing can be installed. The large chassis can be installed with side blowing. The blowing direction should match the air path of the chassis as much as possible. After a good air duct is formed, it can also help the heat dissipation of the memory and the power supply unit.

When choosing a CPU cooler, pay attention to the size. If it is too large, it will suppress the memory slot. Some heat sinks will be made into a "floating" shape, leaving space for the memory, but only the general memory stick can be installed below, with a large The memory of the heat sink is still choking. Also pay attention to the height of the radiator that the chassis can accommodate. It would be embarrassing if the rear cover of the radiator was not attached to the chassis cover.

Heat pipe radiator, don't just look at the quantity

In fact, the thermal conductivity of three or four heat pipes can cope with the heat of high-end processors, so there is no need to pursue a particularly large number of heat pipes. The most obvious influence on the heat dissipation effect is whether the heat pipe can quickly receive heat from the bottom surface, which is related to the contact method of the heat pipe. The heat pipes in this way have been "shaped" or even polished, and they are relatively fragile.

Don't buy expensive radiators, this price is good

In terms of price, the editor recommends that if it is a mainstream configuration such as Core i3 / i5 and Ruilong R3 / R5, choose about 80 yuan to 100 yuan, 2 heat pipes to 3 heat pipes, and a radiator with a large diameter fan. The heat dissipation effect definitely exceeds the boxed original fan. If it is i7, R7, or you want to use overclocking, then 4 heat pipes around 200 yuan + dual fan radiator is enough. With higher specifications of radiators, the brand and design premium have far exceeded the performance improvement, which is very cost-effective.

In addition, when installing a new radiator, be sure to refer to "Poor heat dissipation? Is your silicone grease right? 》 Only the silicone grease can be applied correctly to give full play to the performance of the new radiator.
