22 weeks now and still performing like new “temperature wise”. I use It with a thermaltake core p3 and it does not seem to accumulate dust but i don’t have carpet either. Overall was a great buy, very silent (has different speed modes). Only wish I could control It with software and not Have to press the buttons which could be an inconvinience Depending on how your set up is. Colors are nice and good buy, but the new version seems much nicer.
