Each fan has a different purpose. Some are more for display, some are meant to be basic, some have no RGB and some have all of the RGB possible. Something like this is up to you as a customer and what you want out of the fans. Whether it is a radiator fan or a case fan, you can use them interchangeably but we recommend sticking to their uses, which will be part of the product description.
For instance, if ease of installation is what you are looking for, then our SWAFAN EX is for you because it connects magnetically to the other fans, and all power and data are transferred through one cable.
If cables don't scare you and you are looking for something versatile, our SWAFAN 12 or 14 are for you. The difference here is that the EX fans use magnetics while each of these fans requires a cable going to a controller in order to work.
If you are looking for something basic, without RGB, and are focused on performance, then our Toughfan Series is for you. These are your traditional PWM fans with high CFM and durability.
If you want a basic fan with RGB, then our CT120 and 140's will work for you. They are affordable, look great, and are durable.
However bright, reversible, or magnetic you like your fans to be, we have a fan for you. All of them are focused and cost according to the features you are looking for. Always see the product page for the products you are purchasing for the best examples of look and functionality.
