How to use the CPU thermal cream

Now the heat of the cup is more and more big, so we often paired with a good radiator, but ignore the role of heat conduction paste. Many people install the radiator when forget to apply thermal paste or improper smear, the result of the system is unstable, and even burned the serious consequences of the processor, so good heat conduction paste is very necessary.

　　Preparation of heat-conducting paste before use

You need to carefully clean the smear surface before using the heat-conducting paste. The boxed processor surface is cleaner, and the bulk processor surface may have a lot of dirt and dirt. We should use a clean cotton or cotton wool ball, carefully wipe the surface of the processor. If the dirt is more, you can use alcohol and other volatile, no residue of solvents, the dosage should not be too large, feel the cotton cloth wet. Encounter thicker dirt, to avoid using too hard things to scrape, so as not to affect the smooth surface. After cleaning, the processor is fully dried to ensure the surface dry.

The underside of the radiator is made of copper and aluminum, so they rust. The rusty underside is covered with a layer of gray metal oxide, which loses luster, and the thermal conductivity becomes worse, affecting the performance of the radiator. So the radiator manufacturers will apply a layer of grease on the bottom surface, or cover a layer of transparent film to prevent oxidation. Before using the radiator, these grease and transparent film residue of the gum should be carefully removed clean, you can use household detergent. Similarly, in the end of the cleaning to ensure that the bottom surface of the radiator fully dry, to avoid hard objects scratch the bottom side.

Since cleaning the surface of the metal will soon be oxidized, it is recommended that you clean the processor and heat sink immediately after the thermal paste and install, do not put too long time.

Some of the heatsink for a long time to save the reason, or multiple installations, the bottom has been a certain degree of oxidation. At this time we can use fine sand cloth, uniform in one Direction gently polished, until the bottom of the metal gloss. After grinding, the cleanup work mentioned above will still be carried out.

　Correct smear of heat conduction paste

The main function of the thermal paste is to fill the gap between the processor and the radiator, so the thinner the better. Many friends deliberately on the processor coated a thick layer, in fact, the thicker thermal conductivity is worse, but also prone to the impact of bubbles and other performance. The best smudge tool is hard polyester plastic, such as transparent packaging of the product, or transparencies for the slide projector, cut out a long strip of scissors with a wider width than the processor.

Start with a little heat-conducting paste near the edge of the processor, and then smear it in one direction evenly with a transparent slice, as long as the surface of the processor is covered by a thermal paste. If it is a white thermal paste, you can see the processor thin cover a layer of translucent film, the thickness is just good.

The market also has a flake phase change material thermal paste, directly placed in the center of the processor, you can install the radiator. As for the near-liquid heat conduction paste, it is necessary to put a latex finger on the fingers, then dip in a little heat-conductive paste, evenly smear on the processor surface.

No matter what heat-conducting paste, after removing the radiator, all need to process the surface, apply the new heat-conducting paste to install.
