Pure copper has higher thermal conductivity than pure aluminum. By exchanging heat with air, the heat exchanger can dissipate heat more quickly. This radiator is suitable for notebook computers and some narrow spaces. Through professional air duct design, the contact area with air is increased for heat exchange, and the heat dissipation is faster. Please place the silicone cooling pad between the radiator and SSD to prevent damage to SSD and SSD particles, which can effectively prolong the service life of SSD. It is suitable for dissipation of PC, notebook computer, notebook computer and hard disk to prolong their service life. Equipped with silicone insulation pad and rubber belt, it has performance and more obvious heat dissipation effect. Easy to install and disassemble.
