Just confirming that this cable works and is the right length as well so no y-splitter, adapter, surgery.

My big issue is my fan still goes nuts. In fact, my CPU fan seems to be pegged at a high speed. Anyone have an idea why the CPU fan would spin up and stay ? I hope all the motherboard reinserting stress wasn't too much and broke something. It's not fun having an iMac that sounds like a vacuum.

So you plugged the 22-pin to 13-pin cable from the empty SATA port into the SSD and it causes other fans to spin up? That's weird. Especially since your HDD is exactly the same.
 
Thanks to this thread as well as a few blog posts and other resources, I'm happily computing on my 120gb ocz vertex 2 + Caviar Black 2TB.

A few tips for people about to get at it:

-No matter how good an idea "anti-static gloves" may sound like, do not let the salesman talk you into them over a wristband. Working with those on was so incredibly clumsy. Goodness.

-Having used my torx set to add an SSD in my previous 24", I figured I had all the tools I needed. Wrong. You need "precision" torx tools, as the displays torx screws are recessed about a half centimeter too deep for my "torx multi-tip srewdriver" to reach. My screwdriver was a bit too fat to wiggle in, so I ended up using just the tip and some pliers to get them.

-Don't bother with trying to "just lift" the logic board. I got fed up after an hour of trying to get the SATA on and just unplugged everything and took the board almost totally out. Much easier, and I am hardly "experienced" at this stuff.

-Remember to TAKE OUT YOUR RAM! It slipped my mind for a bit and after I took it out, the logic board came right out.

-No suction cups required. Just Use your fingernails.

-When looking at blog posts or tutorials detailing the procedure, pay CLOSE attention to the orientation of the iMac. I was quite confused at points, because they had the iMac upside down in one photo, or something of the sort.

-I ended up unplugging the HDD SATA and plugging it into the "SDD" designated slot, and vice versa. I thought with the angled connector it fit better this way. It is mis-labled in the profiler, but everything works as it should.

-Don't even bother with "mounting" the SSD. There was hardly enough room to even jam the y-splitter in there, I don't know how people fit a cage of any sort inside.

-Don't let the little stuff slip your mind. Case in point: I had the iMAc back almost totally re-assembled and booted her up. When it asked me where to install the OS, no drives showed up. "OH S$%$^" I thought, and tore the machine apart again. Then I realized that I did not format them with disc utility, only after I had taken the LCD off again!

As for the fans/temps, I just installed SMC first thing, and set the HDD fan at about 5k. Running at 99 degrees just fine.

I don't think the cable was the cause. I think this is the correct cabler to use. When I had the y-splitter solution in there, it did the same thing. Probably something else isn't connected properly. Wish I knew what though.

Definitely DON'T use the y-splitter solution if you haven't bought cables yet.
 
In the imac 27 sata port 1, can i connect this cable?
I use a sata connector from power supply damaged and i connect
to a slimline sata dvd adapter cable.

One cable works...AGAIN!

As mentioned before:
Has 22-pin sata+power female to 13-pin slimline female.
http://www.amazon.com/Slimline-pin-SATA-Female-Cable/dp/B0056OB8GK

That cable works. Just did the install and I have a SATA III connection and some 480+ MB/s read/writes in AJA. I hope to post up my pictures and process a little later. Just need to devise a plan to remove some smudges from behind the glass:(

Fan issues? Where did you place the drive?

This morning I set up the SSD via USB so I could easily just boot from it and it worked nearly flawlessly off the bat (took 3 power button hits to go but everything's perfect now). Fans are silent on the SSD side and of course they're under control on the HDD side with smcFanControl, which I will soon put on the SSD/main side.

I stuffed the drive underneath heat sink apparatus that sits next to the optical drive, it fits there or maybe under the optical drive but the cabling would be tighter.

The install was not that bad for me. I had 0 previous experience taking computers apart. Most annoying thing is getting the motherboard back into place, took me about 20 minutes, because no number of sticky notes can help with that!

Thanks for the info, it is odd how the fans go crazy even when you do not touch the original cables, I am trying to find a solution that does not use fan control software.

I was a little confusing. Currently OSX is installed on both my SSD and HDD. So, I have smcFanControl installed on the HDD but the SSD was a fresh install of OSX (meaning no smc). Neither are acting out of control, it's the correct cable that is needed. I would've liked to have placed the SSD in a bracket but my velcro should work.

Bottom line. The 13 to 22 pin cable mentioned before works flawlessly, no fan issues whatsoever.

Excellent to hear, I am in the middle of my install now, I am using an OCZ vertex 3 120, I am trying a SuperDuper! copy of my boot partition but may need to do a fresh install. Did you do any kind of firmware upgrade on your SSD and are you dealing with trim support in any fashion?

Not sure how I plan to copy my stuff over. I will probably just go old school and do it folder by folder.

Vertex 3 doesn't need TRIM on, in fact it's often slower when the trim enabler is used to activate it through OSX. Didn't think about the firmware update until you just mentioned it but I have a Windows partition to deal with that later ;)

I did not know that about trim, I enabled it with the app, I wonder if I should undo that.

So I am up and running, no major issues, fans are working fine, I used the solution where I took the two cables and soldered it together, I think your solution and cable you used would be nicer, I did put it under the optical drive, it seemed to have a bit more room there.

What worked for me is before I did anything I made a partition on my original hard drive and did an fresh install and had everything up and running just how I wanted it with the new partition as my boot partition, then hooked up the SSD via usb externally, formatted it and used SuperDuper! to make a bootable copy of that partition, then after I put the drive in I was able to boot straight to it.
 
I upgraded my new iMac without a problem you just need a hard drive that is s.m.a.r.t. verified and all works out fine. I used a 3TB seagate barracuda XT. I even took the liberty to install an intel x25m SSD in the third sata port. so i don't know what owc is talking about but for me this was not even close to a problem. "hddfancontrol" is also a handy tool for anyone that is doing this because not all hard drives operate at the same temperatures so it might throw off what mac perceives as hot and run the fans to slow. but thats nothing that should discourage the type of person that would go out and buy a brand new imac only to take it apart the same day. everything checked out perfect when i ran the hardware test as well.

Hi, I want to know if the fans are running on normal speed even without hddfancontrol? Or do you still have to install the hddfancontrol app?

Can I really exchange the Hard drive for another brand/model? Cause I read that someone had problems with the fans.

Are you upgrading for size or because you want to put in a SATA III drive? It's really not worth it to get the SATA III HDD at this point, throw in a SSD and call it a day! No fan issues and a much faster end result
 

That all looks good (why not Intel 510?). But you will also need:
1) Torx T6 for the Airport card, or something, I know you need it. As well as a screwdriver to take out RAM.
2) Some way to blow lint off screen (I used compressed can) and large microfiber cloth
3) A laptop with charged pc walkthrough and I also had iFixit's teardown open as well because some steps weren't clear enough for me

Good luck with install! Shouldn't be too bad. Took me 2 hours with no prior experience (although I like this stuff and am an aero engineer) and another 2 hours to completely clean the debris from the screen (I'm OCD).
 
Ok just to be sure, I have a 27Inch mid 2011 Imac.

I ordered:

Cable:
http://www.microsatacables.com/all-products/slimline-13-pin-sata-female-to-22-pin-sata-female-cable/

SSD:
Intel SSD 320 series 160gb

Torx T10

Is this the way apple does the mid 2011 models?
With this setup there are no fan problems? (also in Windows)?

Has anyone else used this cable from microsatacables.com? I just got done installing my 510 SSD using this cable and it appears the cable only supports 3 GBS data speeds.... or did I do something wrong....? I'm hoping I don't have to redo the whole procedure. Anyhow, this particular cable has the right connections on both ends so it's a winner if you only have a 3 gbs speed SSD. On a positive note, my fans are running at normal speeds after the install. Also, I didn't move any existing cables from the logic board, only added the microsatacables.com cable to the data1 port and hooked that cable up to the 510 SSD

That's my cable and I fortunately have 6Gb/s...before installing I looked at the connections and didn't feel comfortable so I scratched/shined them up a bit. Maybe it's just an update issue on your computer? Seems that this cable has worked for many of us...

Thanks for the reply. Unfortunately for me, I don't know where I went wrong. When I initially installed the SSD I found the link speed under snow leopard 10.6.8 which should have supported the 6 gbs speed. I just did a clean install of Lion on the SSD and I'm still showing the slower negotiated speed....:confused:

Which connections did you clean up? The copper pins on the SSD...?
 
Didn't touch the SSD. Just scraped down the metal on the cable ends, didn't look bright and shiny enough to me so I decided to use the side of a knife or something. Obviously very careful and only slightly scraping. Seems like you have some cabling issue if both OS's didn't show it as 6Gb/s. If/when you do take it apart I would obviously just shine up the SSD connection first, reassemble and see if it works. Then go through the pain of dissembling the motherboard. Good luck! Again, I used that exact same cable except that I ordered from Amazon, same supplier

Sounds like a plan. Will do that this weekend and report back in case others have similar issues.
 
I mean, since you're going to allot time to it this weekend you might as well take the motherboard out again and make sure the other side is nice and clean. It isn't that much of a pain. Annoying yes, but not as annoying as getting all the last bits of dirt and dust from behind the glass panel.
