There is a store in the Central Square Computer City that sells overclocking triple cooling fans. I went to see them last month. The blades were too small and the price was relatively expensive, making them unrealistic. I've looked around the promenade area, but it's too old and looks like it's second-hand. Later, I bought it online. Not only does it have an LED light, it is also silent. If it is empty, I can upload a picture for you to take a look at.
