Founded in 1999, Zaman is a giant in the Korean computer industry, Zalman's product line includes dedicated heatsink and fan solutions for CPUs, graphics card heatsink and fan combinations, laptop coolers, and more. Zaman's notebook radiator is relatively simple in terms of design, with a strong sense of wholeness, and it looks beautiful and atmospheric, and it is also the object of plagiarism by many copycat brands.
 
Zaman's radiator product line is divided into two series: NC and NS. Among them, the NC series is a relatively integrated notebook cooling pad, without a bracket function, and the larger the number of the general model, the more high-end. The NS series, on the other hand, offers a bracket function with multiple adjustable angles.
 
Both the NC2000NT and NC3500 are high-performance single-fan coolers with adjustable fan speed and a USB hub, the latter of which is additionally equipped with a power supply that does not occupy the laptop's interface while providing higher cooling power.
 
NC3 and NC2000T are mainly silent, with a working noise of about 20dBA and a weight of less than 1kg, which is light and portable. In terms of price, ZALMAN is much higher than other brands, and it is not sold on domestic e-commerce platforms, so it needs to be purchased overseas.
