I need help to locate where the smc chip is the logicboard.

Текст:

I have an issue with fan spinning when the iMac is shutdown. SMC and PRAM reseting does not help. From the forum, someone have similar problem with bad smc component on his imac 21”. But as the logicboard design is different than the iMac 27”. Anyone got a boardview so that I can locate the smc part, so that I can take a look if there is some bad component and check it for contuinity?
+=== Update ===
The logicboard has a history of problems. There were a blown L4400 a 120 Ohm 3A fix inductor (ferrite bead) which I have replaced with new one. This fixed fan spinning while the iMac is on. Now the only problem is that it is on while the iMac is shutdown. Beside that the iMac have 2 defective ram slot. Not to mention a brokken glass screen. It is a problem child, but it works at least normally while it is on.
