Here's what the 4/11 (n/c) invoice said: "Removed 2 of the fans and cleaned buildup from housings. Reinstalled fans and ran 48 hrs. Highest fan speed observed was 4400 rpm. Removed midplane and blew out 'pocket lint' blocking airflow in heatsink grid of CP. Reassembled and ran for 3 hrs without fan running above 1800 rpm." Before this service I was seeing the HD fan speeds hit 6k rpm -- even higher sometimes. Right now the HD fan speed is 2806 rpm with a SMART temperature of 145.4°.
