Much better! 4MOT is a bad motor HDD is the HDD fan unit iMac Intel 27" (Late 2009-Mid 2011) Hard Drive Fan. We don’t have guide to get to it, but this guide will get you mostly there! Installing iMac Intel 27" EMC 2429 Dual Drive Kit (HDD or SSD) follow it to Step 33, carefully finish disconnecting the cables from the logic board being careful not the damage anything (there are a few fragile components near the sensor lines). With the logic board fully out you’ll have no problem getting to the fan.
