The product is a CPU cooling fan with a heat sink, designed to effectively dissipate heat and keep the CPU temperature at optimal levels. The heat sink helps to transfer heat from the CPU to the cooling fan, ensuring smooth and efficient operation of the computer system. This component is essential for maintaining the overall performance and longevity of the CPU, making it an important consideration for computer users looking to enhance their cooling systems. I have 5 fans. Looks like they are all diffrent. They all look nee and 2 have the box. I can not test them because i know nothing about fans like this. The one fan may have a broke blade but i cant really tell (see pictures).
