Cooling fan - exact part?
The left fan in my MacBook Pro 17" 2.5GHz (Model A1261) has developed a noise (fluttering sound, bearings?). I got a replacement (sold as for this model), but it looks different from the original.
The original looks like the one on iFixIt's page for this fan, but the replacement I got looks like the one on the page for the Model A1151: same appearance (larger holes than the one in the computer now), design (fan has fewer vanes), manufacturer (Delta), even part # (KDB04505HA). Its connecting cord however is at the correct angle for the 1261 MBP (5 o'clock instead of 3 o'clock). Is this the only functional difference between the fans for the various MBP 17" models?
I'm concerned that having two fans of different designs in the computer might be a problem, since they work together. Does anyone know if this could be a problem?
