How to connect power to SSD iMac 21.5-inch Mid 2011 without loosing hdd temp functionality

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.

Have a look at the guides on the iFix it website.

Try Amazon France, Germany and UK for any cables that you need.

Hi everyone, have a idea of what is the pinouts configuration of the SATA power cable for SSD in iMac Mid 2011 21.5" ? I have a theory but I'm not 100% secure....I think that (in MOBO - SSD Power) Pin#1 = Ground SS / Pin#2 = Empty, Pin#3 = 5V and Pin#4 = Ground....Please if you have made a test or SATA power cable by yourself please let me know the configuration....I want to do that by myself cos' here in my country can't find the cable. Regards...!!!!

If it is the SATA data or power cable then it is identical to pc hardware. That information will be detailed in various websites and videos on the web.

The pinouts of the SSD Power Cable J4531 (PP5V_S0_SATA) are as under:
Pin #1 = 5V
Pin #2 = GND
Pin #3 = NC (Not Connected)
Pin #4 = GND
My problem is I do not know which connector to use. It is 4 Pin Mini Connector, but I do not know the exact part no. and the name of the manufacturer. Otherwise it is very easy DIY cable.
