The Thermaltake 20cm Blue LED Case Fan fan pushes a colossal air flow of 65.3 CFM at 800 RPM. Compatibility is not limited to thermaltake cases either so everyone can take advantage of this colossal fan. A 3-pin to 4-pin peripheral connector adapter is also included, so you can run this fan off either a 3-pin header, or connect it directly to your PSU. With a starting voltage of 9v and a standard rated voltage of 12v, this fan is perfect for connecting to your fan controller so that you can lower or raise the RPMs as required based on PC loading and thermal output.
