Some fan makers also produce coolers, how do we see the cooler they have?

What matters about a good cooler is its overall design and compatibility to what CPU you use. It's not only about a powerful fan or a quiet fan or a fan with whatever kind of clips and heatsinks. Fan makers may offer cooler with better price, but if the cooler they offer can't reach your requirements, do you think they would change their fan and turn to some other fan suppliers? The answer is clear. Global WIN specialize in the overall performance, so we care for cooler's performance always under a total consideration of fan life, heatsink performance, clips and the kind of CPU you use, budget you have of course.
