upgrade hdd to ssd
I need a detailed step-by-step guide on how to upgrade my late 2012 iMac standard hdd drive to SSD with a list of tools needed and from where to buy them. Thanks!

Just so were clear here you are swapping out the HD for a SSD correct?
First you will encounter issues with the built-in thermal sensor and the new thin designed '12 & '13 models use a unitized power & SATA connector so you might have issues fitting the connector on to your SSD.
I would strongly recommend you look at adding the SSD via the dedicated SSD connector on the logic board Vs swapping out the HD. IFIXIT guide to replace or install a SSD unit
With all of the said here is the procedure for replacing the HD use it to take your current HD out and just use your SSD instead of the HD. IFIXIT guide to replace HD
Again, I don't think you want to do this!!
Here's a good writeup on the differences of the '12 & '13 models "Tapered Edge" Aluminum iMac Q&A
iFixit has an excellent hard drive replacement guide for your iMac at - 27" iMac Hard Drive Replacement
Anytime you open your iMac you will need to replace the adhesive foam strips - Adhesive strips
Plastic cards will come in handy. iFixit sells sets of two but old credit or gift cards work fine as well - Plastic cards
The Late 2012 iMacs also require an opening tool to initially cut the adhesive around the display - iMac opening tool
As far as hard drives go you have limited choices in the 3.5" form factor that is native to the iMac. OCZ's Vertex hard drives are available in 3.5" form factor and should work for your application. Alternately you might consider a hybrid drive, one that combines small SSD storage with large traditional platter storage. Seagate's ST2000DX001 is one such model, a 2TB traditional drive with 8GB of embedded solid state storage.
Hopefully that helps!
for the fan issue :
this is a very good working software, you can leave the thermal sensor unplugged and let the fan depend on one of other sensors, and you can choose if the software or the system itself determines when the fan should blow.
So in case you replace your HDD with SSD, which don't have the connector) you can let the HDD fan depend on the ODD sensor and leave the ODD (and LCD) controlled by the system.
The fan will blow full speed at start up but stops once you activate the application .
I let the application start at log in, so once I log in, the fan stops after a moment (about 10 seconds i guess).
Another solution is to order an ODD thermal sensor cable at apple components and stick it on the SSD and plug it into the HHD sensor connector on the logic board, it does the exact same thing as the original thermal sensor cable with the connector) That's a hardware solution (which is normally a better one) but I don not want to open up the Mac again unless i'll put an extra SSD in it in the future. then i might fix it the hardware way.
