APC ACF600 fan replacement model

[syberia81]

One of the 4 fans in my ACF600 is dead. Any idea of the reference for a fan to replace the dead one? After taking off the dead fan, there is no reference on it except sunon, I deduce that it is a sunon fan, 92x92x25 dimension, 12V DC, around 135/4=33 CFM, no speed signal, just ground and 12 V. Does any one has an idea of the sunon reference to use for a replacement? Thank you
