Many people always fall into a misunderstanding when applying silicone grease. They think that the more silicone grease is applied, the better. Theoretically, on the premise that the gap between the processor and the radiator surface can be filled, the thinner the silicone grease layer is. After all, in terms of thermal conductivity, no matter how good the silicone grease is, it can’t be better than copper and aluminum. < / P > < p > therefore, the application of silicone grease needs to be appropriate. It can not be too much or too little, which will affect the heat dissipation of the computer. Today, the author will choose a mainstream 360 water cooling system for testing. The test conditions are: evenly apply silicone grease and do not apply silicone grease for CPU pressure test temperature. < / P > < p > test software: aida64 — use the software for CPU pressure test and temperature monitoring through the software’s sensors. The ambient temperature was 25 ℃. CPU: Intel Core i7 9700K, thermal design power consumption (TDP) is 95w. < / P > < p > CPU without silicone grease: under full load, the power consumption of CPU will reach the maximum, of course, the heat will increase to the maximum at the same time. The measured temperature of i7 9700K is stable at about 75 ℃ after a period of full load. Of course, the standby temperature of CPU is almost the same under different conditions with or without silicone grease. < / P > < p > but in CPU full load test. After applying silicone grease, the CPU full load temperature is about 64 degrees. Without applying silicone grease, the CPU full load temperature is about 75 ℃. The difference between them is about 11 ℃. It can be seen that it is necessary to apply silicone grease to the radiator. Of course, the application of silicone grease also needs skills. It should be uniform, thin and finally covered completely, which is a technical work. [image] Google secretly tests 6GHz networks in 17 states of the United States
