Today I will be looking at the "Bluegears b-COOL120" fan. This fan has a blue LED, and has 8 rows of little lights that lit up to show three important informations. One of them is the RPM, the second one is the temperature of the air being blown out of the case, and the third one tells you if the air that is being blown out of the case is COOL, WARM, or HOT.
