Must be used. Water-cooled radiators also require an appropriate amount of silicone grease to ensure good cooling effects.
The function of thermal grease is to fill the gap between the CPU and the heat sink to conduct heat. Because there is inevitably a gap between an excellent heat sink and a CPU.
Therefore, whether air-cooled or water-cooled CPU radiator is used, thermal grease needs to be used to fill the gap between the CPU and the heat sink so that the CPU can achieve better heat dissipation.
Extended information:
The main function of silicone grease is to help dissipate heat. The CPU and many other chips need to dissipate heat when working, especially under heavy load, otherwise they will burn out.
Therefore, a radiator should be used. However, since the contact point between the CPU surface and the radiator cannot be absolutely smooth, that is to say, there will be many small internal pits (invisible to the naked eye), which affects heat dissipation. The role of silicone grease is to fill these gaps so that the heat dissipation and CPU can conduct heat better.
The difference between CPU thermally conductive silicone resin and thermally conductive silicone resin is that it has no adhesion and will not dry, so re-applying foam thermally conductive silicone resin is very simple, just wipe off the previous cloth or other materials, and Just apply new thermally conductive silicone over the foam.
