Computer overheating how quickly to cooling the CPU cooling?

In order to avoid love machine in the high temperature, you can make a small improvement to their CPU radiator, to pay the lowest cost under the premise of the best heat dissipation effect.

The heat emitted from the CPU core is exported from the copper cover of the CPU, the radiator is first absorbed by the base, then passed to the radiator copper or aluminum heatsink, and then by the fan-generated airflow to take away the heat. Therefore, the heat dissipation effect of the radiator depends on many factors: the material of radiator base, Radiator base and CPU contact area, radiator fin area, fan exhaust air and wind pressure and so on. One of our DIY players can be simple to improve, there are two main parts: the radiator base and the CPU contact area and the radiator matching fan.

First, grinding radiator base

On the surface, the physical contact area between the heatsink base and the CPU is constant (because the CPU cap size is fixed), but the effective contact surface still has the promotion space, may the artificial improvement here explains, the so-called physical contact area refers to the radiator base visual actual area, but if the base contact surface is very rough, and cannot be in close contact with the CPU copper lid, So the effective contact area will be greatly reduced. So in practice, we use the heat sink to apply between the radiator base and the CPU copper cover, the heat transfer effect is enhanced by filling the small gap between the contact surface of the base and the copper cap. If the contact surface is coarser, the larger the gap, the more the heat sink is needed. Even if the best quality of the current silver-containing heat cream or the so-called Nano-technology heat dissipation paste, its thermal conductivity can not be compared with copper. So the first way to improve the radiator is to make the copper face of the radiator base (the same as aluminum) to be polished, so that it is as smooth as possible, then the contact surface of the gap is smaller, heat transfer effect will be better.

Operation Steps

Step 1: First with a clean wet cloth to the radiator base copper surface clean.

Step 2: Lightly on the base copper surface (or aluminum) on the smear a little polishing liquid, because the polishing fluid is irritating, recommended to wear masks and gloves when operating.

Step 3: Put the sandpaper in a good order, start with the trumpet 1000#. Note that the direction of grinding, should be maintained in a horizontal direction after several times, and then from the vertical to the original grinding line to continue grinding several times, and then upgraded to a large number of sandpaper, and finally with 5000# very fine sandpaper repeated gently grinding, Polished to the bottom of the copper has a similar "mirror" effect.

Step 4: Rinse the radiator base repeatedly with tap water until the white cloth is used to wipe no brown material residue on the rag.

Second, increase the cooling fan

To increase the fan exhaust air and wind pressure, the most direct way is to improve the speed of the fan, But at the same time it can also bring about the problem of increasing noise. Practice has proved that many of the fan speed below 1000rpm, noise control is very good, even if the two fans work together, its noise is much lower than a 1500~2000rpm high-speed fan. So we can choose to add a low speed fan to improve the heat dissipation effect of the radiator .

At present, many brands of radiators are using their own dedicated fan buckle, these fasteners are not sold separately, not compatible with each other, So it makes it difficult to add a fan. After careful study of these fan clips, it's not hard to find, in fact, they are the use of better flexible alloy metal strips to make a certain shape to play the role of fixed fans. We can use a large paper clip to copy these clips. First, the large paper clips are gently pulled straight into metal strips, and then according to the original buckle The curvature marks the paper clip with a pencil, then hand the paper clip metal strips into the similar shape of the clip, and finally used to fix the added fan. We can fine-tune the shape of the "cottage" fastener according to the fan's fixed hole position until the fan and radiator are tightly bonded, and there is no resonance phenomenon in actual use.
