May be this help to someone, so i share my experience here. Firts of all sorry for my english i dont speak/write very well.
Most importent at the start. I find involuntarily how to install ssd to this iMac without loosing functionality of managing hdd fun speed on apple logic board, this is most important to this article in my mind. There are many tutorials on the internet how to install ssd, but many of them just say, split the power with Y-SATA power splitter and then manage your loosed hdd fun speed with installing speedfun app.
When i install Samsung 840 Pro 256 GB SSD do my friend iMac 21.5" mid 2011 model i wanted use original power/data SATA connector on logic board but i find something like this:

So i connect just data SATA cabel and put logic board back to iMac:

I dont have Y-SATA power splitter so i just cut original iMac HDD SATA power cables and get power from this cables with this tool:

after:

In other words i made Y-SATA power splitter myself but i find that pin 11 is for temperature sensor, so this is reason why temperature fan speed regulation dont work after apply original Y-SATA power splitter from ebay, because they dont use this pin number 11.
So with this parallel method get the power from original iMac SATA HDD power dont loose functioality of managing hdd fun speed on this iMac. Its fully working after install SSD inside.
Some pictures of my brutal "parallel" metod:

But the main one for share my experience with you is here:
Its pin functionality on power sata connector on the left and apple power sata hdd connector on the right side and how to join them together.

PS: Of caurse the best method is use original power connector for SSD on apple logic board, but i don have time with opened imac to wait 8 day for this connector from ebay ...
