Subject: Reliability of Fans
Does anyone know where I can find reliability data for DC Fan Motors. The fan is used inside a computer and its a 40x40x28mm with ball-bearing construction. I referenced the NPRD data for a Fan, Axial, Tube but the failure rate for 46.8 to 1123.4 for ground benigh. I am esp interested in MTBF vs Temp and Fan Speed. Also, what are the failure modes (lock-up, electrical stress, etc) and % of occurence would be great. Thank you.
