My Problem
My right side fan was going out after a few years of hard service. Time to replace both for good measure.
My Fix
Easy, thanks to your excellent service documentation.
My Advice
One word of caution when replacing fans, make sure that the connectors are completely seated. I checked my fan RPMs using iStat immediately after the initial power on, post repair. My right fan was turning at zero RPM. I popped the cover and reseated the connector. powered up and observed it spinning. Checked iStat and have continued to do so every few operating hours. All is well at around 2K RPM.
